Steve Holliday added: "In the UK, we submitted comprehensive business plans for our Transmission businesses to Ofgem, incorporating the output of the significant stakeholder consultation which is critical to securing investment in this essential UK infrastructure. At the same time, we continued to invest in the engineering teams and processes to allow us to deliver the major step up in capital investment over the next few years.

In the US, we delivered our new operating model on time, significantly reducing headcount and embedding our new regional structure. I am confident that this new structure will improve customer service in our jurisdictions and underpin the continuing drive for efficiency in our US operations and the associated improvement in financial performance.

As a result, notwithstanding the exceptional US weather, we remain well positioned to deliver another good year, although comparative progress will be impacted by the timing differences that benefited 2010/11."

BUSINESS REVIEW

National Grid delivered good operational and financial performance in the first half of the year. In May, we set out our strategic priorities for 2011/12, focused on delivering our core investment programme, implementing our new operating model and achieving our cost reduction programmes.

At the same time, we sustained our focus on delivering the level of service that our customers need and continue to operate in a way that places safety at the forefront of our considerations. We kept our lost time injury rate consistently low and continued our work on further enhancing process safety. We will use the lessons learned from incidents over the period to further reduce risks for our people, our customers, our contractors and the public. We made significant improvement in our customer satisfaction performance scores in our UK Gas Distribution business and further improvements in reliability in our US operations, excepting the impact from the extreme weather in the US.

Growth and Investment

Growth in our core asset base, underpinned by good regulatory frameworks that focus on operational cost efficiency and customer service to provide incentive driven performance, is a major driver of long term value creation for our investors.

We continue to invest in regulated assets at rates significantly in excess of depreciation levels looking to invest capital only where we expect to be able to earn an acceptable return. Capital investment(5) in the period decreased by GBP160m, compared to the same period in 2010/11 on a constant currency basis led by a reduction in expenditure related to our other activities, including non-regulated businesses and joint ventures.

In July, we submitted to Ofgem our UK Transmission business plans for the eight years from 2013/14 through to 2020/21. These plans set out proposals for a material increase in capital investment, driven mainly by the changes in the UK generating fleet, including additional wind generation as well as new gas and nuclear power stations. As a result, taken together with investments in 2011/12 and 2012/13, our UK Transmission regulated asset value (RAV) would be expected to increase to over GBP35bn by March 2021 from the GBP13.3bn we reported at March 2011, an annual growth rate of around 10%.

Regulatory developments in the UK

In August, Ofgem published its initial proposals for the one year rollover of the Transmission Price Control Review 4 (TPCR4) to cover the year 2012/13. These proposals set out a proposed increase in allowed revenues for both Electricity Transmission and Gas Transmission. This increase is driven in part by the growth in RAV due to our increased capital investment over recent years. The proposals also recommended that real returns on equity remain unchanged at 7.0% and that the real cost of debt be reduced from 3.75% to 3.25%, reflecting underlying changes in the cost of borrowing in recent years. Final proposals are expected in November, with the new control running for one year from 1 April 2012.

The subsequent price control period will be for the eight years from 2013/14 through 2020/21. This will be the first price control under the new RIIO regulatory framework, set out by Ofgem in July 2010. In July this year, we submitted business plans that set out GBP31bn of total expenditure (totex) over the eight year period, including proposals for incentive schemes, revenue adjustment mechanisms and our view of the financing requirement for these plans. This included a proposed 7.5% return on equity, a 55% notional gearing level (i.e. 55% debt and 45% equity in the notional businesses) and a 16 year (2 price control periods) transitional arrangement for our Electricity Transmission business around changes to future asset depreciation.

In October, we received Ofgem's initial assessment of our business plans. Feedback on many areas was positive and identified areas for further consultation and clarification over the coming months. As expected, we were not identified for potential fast-tracking and now have clarity on the timings of the next steps in the process. We will develop our business plans further and following ongoing discussions with stakeholders will submit updated plans in March 2012. Subsequently, initial proposals are expected in July 2012 with final proposals by the end of 2012, to come into effect from 1 April 2013. Our UK Gas Distribution businesses will submit their business plan in November 2011.

We continue to believe that the emerging regulatory framework around our future investment plans will present National Grid with positive opportunities to invest for long-term profitable growth and reasonable returns.

Regulatory developments in the US

As set out in our full year results in May, further rate-filings in a number of our US jurisdictions will be an important component of our long term performance improvement in the US, allied with delivering further improvements in customer service and cost efficiency. By combining new filings with more efficient operational and capital investment processes we are seeking to achieve and sustain higher returns from our combined US operations than the current level.

Consistent with the objective to be responsive to our regulators in each of the jurisdictions in which we operate, we have been making a number of changes to our organisational model, cost base, accounting systems and processes. These changes are already providing a much stronger alignment around managing regulatory engagement and customer service, as well as delivering necessary changes to our controls and accounting processes, in line with the recommendations set out in the recent Liberty Consulting Group audit of our US operations.

In July we filed with the New York Public Service Commission (NYPSC) for the recovery of $236m of deferred costs in Niagara Mohawk Electric, in line with the timetable set out in the rate case approved in January 2011. These recoveries relate to costs that have been incurred by the business over a number of years in relation to pensions, environmental costs, capital expenditure and other activities not yet charged to customers. We expect an order from the NYPSC in December for cost recovery commencing in January 2012. We continue to work with Overland in respect of the audit of our upstate New York business which was commissioned by the NYPSC last year.

In November, the Massachusetts Department of Public Utilities issued an order in response to our request to correct certain calculation errors appearing in the gas rate order issued last year. The new order issued approved a further increase in gas distribution rates of $2.8m p.a. We are awaiting a decision in response to another pending request for reconsideration of other issues in the same case.

Our appeal of certain aspects of the Rhode Island Commission's last electric rate order in 2010 continues. The highest court in the state heard oral arguments in relation to this appeal and a decision is expected by the end of this calendar year. In the period, revenue decoupling mechanisms were put in place for our Rhode Island businesses.

We continue to expect to file new gas and electric rate cases for Niagara Mohawk in New York and Narragansett in Rhode Island in 2012.

Efficiency Programmes

National Grid has a number of efficiency programmes underway in different parts of its business to ensure the cost effective delivery of our services and investments.

The first release of our Gas Distribution Front Office system was rolled out across all of our UK Distribution networks and the second release was rolled out in two of our networks. Roll out will continue into the remaining two networks after the peak winter workload period is completed, together with the continuation of the third release. In addition, implementation of a revised UK Gas Distribution structure was substantially completed in October, involving a number of management and staff changes. These initiatives are designed to bring our businesses closer to the efficiency frontier of all UK gas networks. We have already seen both absolute and comparative improvements in customer satisfaction scores in our UK gas networks with further benefits expected later this year and in 2012/13.

Implementation of our new US organisational model has been completed, together with a reduction of over 1,150 mostly management and administrative positions. Benefits of the changes are already being seen with a stronger jurisdictional focus and reductions in controllable costs.

Strategy

The Group's strategy is unchanged. In early 2011/12 we set out how we manage our business using a portfolio approach. We own developed assets with minimal investment requirements and strong cash generation, businesses with low to medium levels of growth and positive cash generation, and businesses with high levels of investment and growth. Maintaining an appropriate mix of businesses enables our portfolio of activities to deliver an overall balance between long-term capital growth and cash generation for the benefit of our shareholders.

This year we streamlined the business further through a number of small divestments. In October, we completed the sale of our Seneca Upshur exploration and production business for $153m and the sale of our OnStream UK unregulated metering business for GBP274m.

In addition, the agreed sale of our Granite State Electric and EnergyNorth businesses in New Hampshire, for $285m, continues to progress, subject to regulatory approvals.

New return metric

We outlined in May our intention to publish clear, comparable measures of financial performance for our UK and US businesses. At an operating company level, we will continue to publish our regulated returns, which are clearly understood and are a very effective way of managing towards our regulated targets and driving efficiency. However, due to differences in the way each regulator sets these targets, these are not suitable measures for comparing each part of the business with one another. Our new return metric is intended to look through these differences and provide a measure that can be used, in conjunction with others, to assess future investment decisions.

This measure of return on capital employed ("RoCE") is designed to show a better comparison between our UK and US businesses and set out in detail one of the measures that we use to make decisions around our portfolio and our investments. Our RoCE calculation is a post-tax measure based on an IFRS operating profit measure less taxation at the statutory rate. We make adjustments to capture the difference between the treatment of certain costs, including taxation and pension costs, by regulators and their treatment in the financial accounts. We adjust to better match the costs and the timing of recovery of revenues associated with those costs and to take account of the impact of inflation on UK regulated returns. The capital employed is, in so far as possible, consistent with the regulated capital as defined in our regulated return on equity calculations.

The RoCE for our businesses over the last two years is shown in the table below:

 
                 2010/11   2009/10 
--------------  --------  -------- 
 UK Regulated     8.5%      9.6% 
 US Regulated     7.1%      5.5% 
 

The movement in UK Regulated RoCE was principally caused by the lag in RPI indexation benefits on UK allowed revenues which, as a result, did not increase materially in 2010/11. In contrast, the RAV increased as a result of actual inflation over the year to March 2010 of 4.4%. In the US, the improved RoCE was the result of stronger performance and increased revenues under new rate plans. The 140 bps difference for 2010/11 between the UK Regulated and US Regulated RoCE largely reflects a US business which, while improving significantly, does not yet meet our expectations. A detailed breakdown of our RoCE calculation is available on page 20 of this statement.

Financing

Our balance sheet remains in a strong position. Contributing to this are strong cash flows from the business and growth in our regulatory asset base. The latter item is partly driven by the positive impact of retail price index (RPI) inflation, currently running at over 5% p.a., approximately 2-3% above long term rates. Our UK RAV, which was approximately GBP21bn at 31 March 2011, increases each year with RPI inflation. As a result, higher inflation delivers a stronger financial position by increasing growth in our regulatory asset base by around GBP500m in the first 6 months of the year, partially offset by the impact of accretion on our RPI-linked debt.

Board changes

In December 2011, Sir John Parker will step down from his position as Chairman of the Board of National Grid after over 10 years as Chairman of National Grid and previously Lattice Group. Sir Peter Gershon joined the Board as Deputy Chairman on 1 August and will assume the role of Chairman of the Board of National Grid when Sir John steps down with effect from 1 January 2012.

In July, John Allan, a non-executive director of National Grid for the last six years, stepped down from the Board. In September, Ruth Kelly, Managing Director, HSBC Global Asset Management and a former UK government minister, joined the Board as a non-executive director.

DIVIDEND

The Board has approved an increase in the interim dividend to 13.93p per ordinary share ($1.0967 per American Depositary Share) in line with our policy of targeting 8% growth until March 2012. The interim dividend will be paid on 18 January 2012 to shareholders on the register as at 2 December 2011. A scrip dividend alternative will again be offered.

The existing dividend policy expires in the current financial year and so applies to the interim dividend to be paid in January 2012 and the final dividend to be paid in August 2012. We expect to announce a one year policy in January 2012 to cover the year 2012/13. During 2013, we expect to announce a dividend policy to run from 2013/14 onwards, after the outcomes of the RIIO price control reviews are known.

OUTLOOK

The strategic priorities we identified for the 2011/12 financial year remain unchanged: developing our portfolio of assets to maximise value for shareholders, delivering our investment programme in a disciplined manner, improving returns in our US business, inputting to the development of the UK regulatory framework and continuing to drive efficiency across the business.

The restructuring of our US business is now largely complete and is delivering operational and financial benefits to underpin our progress on further improving US returns alongside our efforts for further cost reductions. Our existing price controls in the UK continue to deliver attractive returns and we are working to ensure that this can continue under the RIIO framework.

As a result, notwithstanding the impact of some exceptional US weather, we remain well positioned to deliver another good year, although comparative progress will be impacted by the timing differences that benefited 2010/11.

BASIS OF PRESENTATION

Unless otherwise stated, all financial commentaries are given on a business performance basis(6) at actual exchange rates. The results for the period are presented in line with the new reporting structure, separated into segments for our UK Transmission, UK Gas Distribution and US Regulated businesses. The results for the same period last year have also been re-presented in these new segments.

Under our regulatory frameworks, the majority of the revenues that we are allowed to collect each year are governed by a regulatory price control or rate plan. If we collect more than this allowed level of revenue, the balance must be returned to customers in subsequent years, and if we collect less than this level of revenue we may recover the balance from customers in subsequent years. These variances between allowed and collected revenues give rise to "over and under recoveries". In addition, in the US, a substantial portion of our costs are pass-through costs (including commodity and energy efficiency costs), and are fully recoverable from customers. These timing differences between costs of this type being incurred and their recovery through revenues are also included in over and under-recoveries. We identify these timing differences in order to enable a better comparison of performance from one period to another.

Allowed revenues for our UK regulated businesses are set on an annual basis. Over and under-recoveries in the first 6 months of the year in these businesses, described as "timing differences", are therefore estimates based on an assumed allowed revenue profile. Opening balances of under and over-recoveries have been restated where appropriate to correspond with regulatory filings.

-------------------------------  ---------------  ---------------  ----------------- 
 

As a result, operating profit excluding timing increased by GBP26m (2%) on a constant currency basis. This increase was partly driven by an increased contribution of GBP30m from our other activities, principally our Grain LNG and our UK metering businesses. In our regulated businesses, net regulated income increased by GBP86m partly due to the impact of RPI+X indexation on our UK regulated revenues. Post-retirement costs(8) decreased by GBP3m and bad debts increased by GBP3m. Depreciation and amortisation increased by GBP7m and regulated controllable costs increased by GBP16m. This excludes the impact of Hurricane Irene in the US, which decreased operating profit by a further GBP69m. Other costs, including property taxes and capex related costs decreased by GBP2m. The period-on-period movement in exchange rates decreased operating profit by GBP28m. As a result, reported operating profit for the period was GBP1,420m.

Across our businesses, regulated controllable costs increased by GBP16m (2%) on a constant currency basis compared to the same period last year, reflecting inflationary pressures on salaries and other costs and some increased recruitment in our UK transmission business. The continued drive for efficiency in our businesses and some early impacts from our US cost saving programme helped to mitigate these impacts. Adjusting for inflation, regulated controllable costs reduced by 1.6% in real terms.

Net finance costs were GBP468m, 15% lower than the same period in 2010/11 at constant currency partly driven by lower average net debt and lower pension interest.

Profit before tax was up 2% to GBP953m.

The tax charge on profit was GBP254m, GBP25m lower than the same period last year, reflecting an increased proportion of UK profits and a lower UK tax rate. For the same reasons our effective tax rate decreased to 26.7% from 29.7%.

As a result, earnings were up GBP41m on the same period last year at GBP697m. Earnings per share decreased 2% from 19.9p (restated) last year to 19.6p, reflecting the increased weighted average number of shares in the first 6 months of the year compared to the same period last year, as new shares resulting from the rights issue only impacted this measure part way through the period in 2010.

Exceptional items and remeasurements and stranded cost recoveries increased statutory earnings by GBP98m after tax. A detailed breakdown of exceptional items, remeasurements and stranded cost recoveries can be found on page 29. Included in exceptional items are a provision of GBP54m related to environmental remediation liabilities and a GBP55m charge relating to severance and pension costs associated with our US restructuring programme. After these items and non-controlling interests, statutory earnings for continuing operations attributable to shareholders were GBP795m. Statutory basic earnings per share from continuing operations were 22.3p compared with 23.1p (restated) for the same period last year.

Operating cash flow, before exceptional items, remeasurements, stranded cost recoveries and taxation, was GBP1,802m, GBP131m lower than the same period in 2010/11.

Funding and net debt

Net debt rose to GBP20.0bn at 30 September 2011 compared with GBP18.7bn at 31 March 2011, reflecting the impact of our investment programme and foreign exchange movements, which increased debt by GBP342m due to the strengthening of the US dollar.

We continue to utilise our cash balances to invest in capital expenditure and retire maturing debt. As a result, at 30 September 2011 cash and cash equivalents and short term financial investments were GBP3.0bn, compared with GBP3.3bn at 31 March 2011.

Despite having cash within the group at this time, our approach to long term debt financing is unchanged and we continue to issue long term debt where attractive opportunities exist. As a result, in October we issued a total GBP273m of index-linked retail bonds from National Grid plc at a real coupon of 1.25%. This is the largest retail bond issued in the UK and the first index-linked retail bond ever issued by a company in the UK debt markets. We also issued a 4 year maturity EUR500m note from National Grid USA in May, paying a coupon of 3.25%.

US Regulated Return on Equity calculations

As part of the development of our new published return metric, we reviewed our US Regulated Return on Equity calculations with particular attention to the recent rate case outcomes that have occurred since we began publishing these metrics.

We have made some adjustments to the calculations to simplify them and account for inconsistencies between the treatment of certain items by different regulators. We have also focused on the definition of rate base used by the regulators when setting recent rate plans. We are publishing the results of these revised calculations for the calendar year 2010 plus comparatives for the year 2009. The revised calculation methodology will be used for the current calendar year. The results of the revised Regulated Return on Equity calculations are provided below.

US Rate Base as at 31 March

Going forward we are proposing to publish an estimate of rate base as at 31 March rather than as at 31 December. This is intended to better aid comparability between the published UK RAVs and the published US rate base numbers and match with our other reported financials. It will also form the basis of the Return on Capital Employed calculation.

The value of our reported rate base changed between December 2010 and March 2011 for a number of reasons. The point in time at which the rate base is reported affects the value, in part due to the movement in working capital between December and March in our US gas businesses as gas stocks are utilised over the winter heating period. In addition, the move to using the latest regulatory definition of rate base particularly affects our Massachusetts and downstate New York gas businesses, which had previously used invested capital as an estimate of rate base. As a result, as at 31 March 2011, $600m of regulated assets are now classified in this method of presentation as outside the regulatory definition of rate base in those companies. As before, we expect to recover these and, for over half, to attract a return under the regulatory arrangements in the meantime. As a result of these changes, the rate base used for the purpose of calculating Regulatory Return on Equity for 31 March 2011 would have been $14.3bn.

TECHNICAL GUIDANCE

We provide technical guidance to aid consistency across a range of modeling assumptions of a technical, rather than trading or core valuation, nature. We will provide appropriate updates to this information on a regular basis as part of our normal reporting. The outlook and technical guidance contained in this statement should be reviewed together with the forward looking statements set out in this release in the context of the cautionary statement.

Further information about our principal risks and uncertainties for the next six months of the financial year is provided in Note 14 on page 35.

Earnings Items

There are no changes to the items described as "technical guidance" in relation to earnings items given at the time of results in May 2011. In addition to those items, we are providing the following additional technical guidance.

We expect net finance costs to be approximately GBP100m lower in the current year than 2010/11. This is partly due to an expected GBP50m movement in the non-cash pension finance charge. In addition continued low interest rates on new debt and the maturity of existing, higher coupon debt, are expected to contribute around a further GBP50m reduction in net finance costs.

We expect the impact of US storm costs to adversely affect reported earnings for 2011/12. In the first half of the year the impact of Hurricane Irene had a negative GBP69m impact on operating profit. We expect this to be reflected in the full year results along with an estimated GBP50m impact from the snow storms experienced in the US in October. Recovery of storm costs in jurisdictions outside of Long Island will be subject to filings that, with the exception of the deferral filing in upstate New York, are unlikely to be approved before the end of the financial year.

Investment and other items

Capital expenditure(5) for 2011/12 is expected to be in the range GBP3.2bn to GBP3.3bn, lower than the prior year due mainly to reduced investment in our non-regulated businesses and joint ventures, particularly Grain LNG and BritNed. In the US, investment is now expected to be at the low end of our medium term guidance of GBP1.0bn - GBP1.2bn per annum, largely reflecting the benefit of a stronger regional focus on prioritising activities and exchange rate movements. In the UK, forecast investment in Gas Distribution remains in line with expectations, albeit lower than the prior year. Investment in UK Transmission is expected to be lower than early forecasts, reflecting process and procurement efficiencies and re-phasing of projects to align with updated regulatory funding allowances.

There are no other changes to the items described as "technical guidance" in relation to investment and other items given at the time of results in May 2011. In addition to those items, we are providing the following additional technical guidance.

The UK RAV is adjusted each year to account for RPI inflation in the UK. Based on the assumption that inflation at March 2012 will be approximately 4% year-on-year we expect our UK RAV to grow to over GBP22bn by March 2012.

Performance in the first 6 months of 2011/12

UK Transmission operating profit was down GBP43m (7%). This included an estimated under-recovery of revenues of GBP23m in our regulated businesses. Combined with an opening balance of GBP7m owed to the business from previous years, this leaves a total balance owed to our businesses as at 30 September of GBP30m which, in the normal course of events, would be recovered in the second half of the year. In the same period last year, revenues were over-recovered by an estimated GBP31m. As a result, adjusting for the timing differences of GBP54m, operating profit for the period excluding timing increased by GBP11m as set out in the following table.

-------------------------------  ---------------  ---------------  ----------------- 
 

The increase in operating profit excluding timing reflected GBP38m of increased net regulated income driven by RPI+X indexation on UK regulated revenues and included a GBP14m decrease in French Interconnector auction revenues partly as the result of essential maintenance work. Depreciation and amortisation increased by GBP13m, reflecting the growth in asset base due to our investment programme. Regulated controllable costs increased by GBP15m partly reflecting further investment in people as the business continues to prepare for the RIIO review and the associated increase in investment workload. Post-retirement costs increased by GBP3m and other costs decreased by GBP4m. As a result, reported operating profit for the period was GBP602m.

We are preparing the business for a period of increased capital expenditure whilst maintaining our focus on efficiency and customer service. We have also enhanced our internal capabilities by recruiting 162 new engineers. At the same time we have published our Transmission customer commitment detailing how we will communicate with customers and deliver what they need while we are significantly expanding our existing network.

As we outlined in the business review, we filed our business plans for RIIO in July and received Ofgem's initial view of these plans in October.

Investment activities in the first 6 months of 2011/12

Capital investment in our UK Transmission business for the period was GBP603m, GBP24m down on the same period last year. Investment in new gas transmission pipelines reduced compared to the same period last year and contributed to a GBP34m reduction in gas transmission spend. Partly offsetting this, we increased capital investment in electricity transmission by GBP10m. We have increased investment in our London cable tunnels project and are continuing to invest in other major load related projects. We also increased investment to enhance the security, reliability and efficiency of our system through our programme of non-load related investment.

Future activities and outlook

The outlook for our UK Transmission business for the remainder of the year is unchanged. We expect continued upward pressure on operating costs, in part due to our recruitment of more engineers to deliver our investment programme. Offsetting this are increased revenues from indexation and higher gas transportation tariffs in the second half of the year.

-------------------------------  ---------------  ---------------  ----------------- 
 

The increase in operating profit excluding timing reflected GBP37m of increased net regulated income driven by the impact of RPI+X indexation. Regulated controllable costs increased by GBP7m with the impact of inflation and resources to support the implementation of new systems. Depreciation and amortisation increased by GBP10m and other costs increased by GBP4m. As a result, reported operating profit for the period was GBP381m.

As part of our drive to improve efficiency and customer service we are restructuring and transforming our Gas Distribution operations. We have made improvements in both areas, with customer satisfaction improving whilst holding regulated operating costs approximately flat in real terms compared to the same period last year. As discussed in the business review, we have implemented the second release of our Front Office system in two of our four gas networks to date.

The new systems and ways of working have been designed to enable us to ramp up our efficiency by giving our people excellent technology and tools. These new systems are expected to give us a better view of our assets, where they are and what work is being done on them. They are designed to assess what skills are required to complete the work and match those needs to the right people. As a result, we expect to significantly improve our capability to profile our workload and resources across the year, and dispatch work to the right individuals with the right skills at the right time.

Investment activities in the first 6 months of 2011/12

Capital investment in our UK Gas Distribution business continues at a broadly steady rate and continues to be dominated by our work on mains replacement, which accounted for GBP245m of our total GBP325m capital expenditure for the period. This was GBP4m down on the same period last year mainly due to a reduction in spend on information systems.

Future activities and outlook

The outlook for our UK Gas Distribution business for the remainder of the year is unchanged. One of our key priorities for the year is to provide the foundation to bring our networks closer to the efficiency frontier that Ofgem measures. We will continue our restructuring to drive further efficiencies in our operations. We plan to close our Northampton site and consolidate operations on our Hinckley site once the peak winter workload period has completed.

We will file our business plans for the period April 2013 to March 2021 with the regulator at the end of this month as part of the RIIO price control process. We expect to see feedback on these plans in February 2012, with initial proposals in July 2012 and final proposals towards the end of 2012, with the control running for eight years from 1 April 2013.

Performance in the first 6 months of 2011/12

US operating profit was down GBP46m (13%) on a constant currency basis. This included the return of GBP25m of revenue owed to customers from over-recoveries in previous years. Combined with an opening balance of GBP96m owed to customers from previous years, this leaves a total balance owed to customers as at 30 September of GBP71m which, in the normal course of events, would be returned in the second half of the year. In the same period last year, revenues were under-recovered by GBP10m. As a result, adjusting for the timing differences of GBP15m, operating profit for the period excluding timing decreased by GBP31m, as set out in the following table.

The reduction in operating profit excluding timing also included a GBP69m charge in respect of Hurricane Irene. As a result, operating profit, excluding the effect of timing and Hurricane Irene, increased by GBP38m. Net regulated income increased by GBP11m, partly due to increases from new rate cases in our Massachusetts gas businesses, offset by a reduction in income from our New York electricity business where warm weather in the same period last year positively impacted profits excluding timing. Depreciation and amortisation decreased by GBP16m primarily due to a reassessment of our asset lives. Regulated controllable costs reduced by GBP6m, post-retirement costs decreased by GBP6m and bad debts increased by GBP3m. Other operating costs decreased by GBP2m, excluding the GBP69m impact of Hurricane Irene mentioned earlier. The period-on-period movement in exchange rates had a GBP28m unfavourable impact on operating profit. As a result, reported operating profit for the period was GBP306m.

The impact of Hurricane Irene, flooding and tornadoes in Massachusetts combined to make it an exceptional summer for weather in our US operating territory. In the immediate aftermath of Hurricane Irene, over 30% of our US electricity customers were without power. Around 3,500 of our non-field force employees combined with our front line employees to contribute to the restoration efforts. As a result, 90% of our customers were restored within 5 days. Over 12,000 employees and contractors were mobilised, working in excess of an estimated 1 million man hours.

The costs to date of Hurricane Irene within the Long Island Power Authority service territory have not significantly impacted operating profit as we expect to recover prudently incurred storm costs with minimal lag under our contractual arrangements. These represent approximately 60% of the total costs of the hurricane within the areas we serve. We have filed for recovery of a substantial portion of the estimated costs in upstate New York and expect to file for the remaining recoverable costs which are not already covered by existing storm funds in our other territories. The timing of recovery will vary by jurisdiction and recovery of the costs is expected to positively impact operating profit in future periods.

These exceptional storms will clearly have affected the reliability performance in our US business and we expect that these impacts will be exempted from any regulatory measure. Prior to the impact of the storms, progress in our US business was positive, with further improvements in reliability in our US operations.

Despite the exceptional weather, we have continued with our cost reduction programme targeting a run rate of $200m of savings by March 2012. The final appointments into the structure were made in September and the transition to the new structure with jurisdictional focus is now complete.

Investment activities in the first 6 months of 2011/12

Capital investment in our regulated US business continues at a broadly steady rate. Capital expenditure for the period was GBP462m, GBP59m down on the same period last year, primarily due to movements in exchange rates. On a constant currency basis, capital investment was GBP21m lower than the same period last year. We increased spend on the New England East-West System transmission project, offset by lower spend in our upstate New York electric business.

Future activities and outlook

The outlook for our US business for the remainder of the year, excluding the impact of storms and timing is unchanged. The full year results are expected to be impacted by the storms we have experienced to date.

As discussed in the business review we have filed for the recovery of deferred costs in our Niagara Mohawk Electric business. These will not impact the 2011 Regulated Return on Equity that we will report for Niagara Mohawk. Also, in 2011, benefits from the cost reduction programme will be offset by the non-recurrence of a one-off benefit from warm weather experienced last year, before decoupling came into effect. We do not expect returns to improve materially in that business until both the benefits of new rate filings and the cost reduction programme are achieved. For the US overall, the outlook for returns in 2011 remains positive.

We continue to progress with the implementation of a single financial system across all of our US businesses. This system will address a number of findings from the Liberty audit and is expected to deliver greater transparency and consistency of cost treatment.

* Excludes investment in joint ventures.

Operating profit from our other activities increased by 30% to GBP131m. This was mainly driven by an increase in operating profit from our Grain LNG and Metering businesses.

Metering operating profit was up GBP10m at GBP97m. During the period, capital investment in this business was GBP35m. GBP12m of Metering operating profit and GBP12m of Metering capital investment related to the OnStream business which was sold in October this year. In our National Grid Metering business, the contracts which governed the majority of our meter charges last year were not in place for the first six months of the current year. The affected customers have instead been charged for regulated services at the full tariff cap rate, resulting in an increase in revenues and operating profit.

Our Grain LNG business delivered an operating profit of GBP45m, up 61%. The phase III capacity expansion, which commenced commercial operations in December 2010, made an increased contribution to operating profit in the first half of the year. As construction of phase III completed last year, capital investment in Grain LNG was GBP24m lower period-on-period.

Our Property business delivered an operating profit of GBP18m, up 50%. The increase relates to our lettings business, with profits from disposals at approximately the same level as the first 6 months of 2010/11.

Other capex increased by GBP7m to GBP43m. This principally represents spend on US financial systems.

JOINT VENTURES

In the first half of this year we did not invest further in our joint ventures compared to GBP72m in the same period last year. The reduction in investment is principally due to the completion of the BritNed interconnector between England and the Netherlands, our joint venture with TenneT, which entered commercial operation on 1 April 2011. In addition capital investment in our Millennium Pipeline joint venture completed last year.

CAUTIONARY STATEMENT

This announcement contains certain statements that are neither reported financial results nor other historical information. These statements are forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. These statements include information with respect to National Grid's financial condition, its results of operations and businesses, strategy, plans and objectives. Words such as 'anticipates', 'expects', 'intends', 'plans', 'believes', 'seeks', 'estimates', 'targets', 'may', 'will', 'continue', 'project' and similar expressions, as well as statements in the future tense, identify forward-looking statements. These forward-looking statements are not guarantees of National Grid's future performance and are subject to assumptions, risks and uncertainties that could cause actual future results to differ materially from those expressed in or implied by such forward-looking statements. Many of these assumptions, risks and uncertainties relate to factors that are beyond National Grid's ability to control or estimate precisely, such as changes in laws or regulations and decisions by governmental bodies or regulators; breaches of, or changes in, environmental, climate change and health and safety laws or regulations, including breaches arising from the potentially harmful nature of its activities; network failure or interruption, the inability to carry out critical non network operations and damage to infrastructure, due to adverse weather conditions including the impact of Hurricane Irene and other storms; performance against regulatory targets and standards and against National Grid's peers with the aim of delivering stakeholder expectations regarding costs and efficiency savings, including those related to investment programmes, restructuring and internal transformation projects; and customers and counterparties failing to perform their obligations to the Company. Other factors that could cause actual results to differ materially from those described in this announcement include fluctuations in exchange rates, interest rates and commodity price indices; restrictions in National Grid's borrowing and debt arrangements, funding costs and access to financing; National Grid's status as a holding company with no revenue generating operations of its own; inflation; seasonal fluctuations; the funding requirements of its pension schemes and other post-retirement benefit schemes; the loss of key personnel or the ability to attract, train or retain qualified personnel and any disputes arising with its employees or the breach of laws or regulations by its employees; accounting standards, rules and interpretations, including changes of law and accounting standards and other factors that may affect National Grid's effective rate of tax; and incorrect or unforeseen assumptions or conclusions relating to business development activity. For a more detailed description of some of these assumptions, risks and uncertainties, together with any other risk factors, please see National Grid's filings with and submissions to the US Securities and Exchange Commission (the 'SEC') (and in particular the 'Risk factors' and 'Operating and Financial Review' sections in our most recent Annual Report on Form 20-F). The effects of these factors are difficult to predict. New factors emerge from time to time and National Grid cannot assess the potential impact of any such factor on its activities or the extent to which any factor, or combination of factors, may cause results to differ materially from those contained in any forward-looking statement. Except as may be required by law or regulation, National Grid undertakes no obligation to update any of its forward-looking statements, which speak only as of the date of this announcement.

METRIC DEFINITIONS

The financial metrics we have reported today are designed to give greater transparency on National Grid's relative performance and our performance against regulatory contracts.

US REGULATED RETURN ON EQUITY (nominal)

This is a US GAAP metric as calculated annually (calendar year to 31 December).

Calculation: Regulated net income divided by equity rate base.

-- Regulated net income calculated as US GAAP operating profit less interest on the adjudicated debt portion of the rate base (calculated at the actual rate on long term debt) less tax at the adjudicated rate

-- Regulated net income is adjusted for earned savings in New York and Narragansett Electric and certain material specified items.

-- Equity rate base is the average rate base for the calendar year as reported to our regulators or, where a reported rate base is not available, an estimate based on rate base calculations used in previous rate filings multiplied by the adjudicated equity portion in the regulatory capital structure

_________________ (1) Excluding exceptional items, remeasurements and stranded cost recoveries. For definition of business performance results see footnote 6. (2) Hurricane Irene struck the North East US on Sunday 28 August 2011, affecting power supplies to over 1 million National Grid customers. (3) \'Constant currency' comparison uses recalculated results for H1 2010/11 using the average US$ exchange rate for H1 2011/12. For detailed definition of currency adjustments see footnote 7. (4) Prior year EPS adjusted to reflect the additional shares issued as scrip dividends, refer to note 7 on page 33.

(5)    Including investment in joint ventures (6)    Business performance results are the primary financial performance measure used by National Grid, being the results for continuing operations before exceptional items, remeasurements and stranded cost recoveries. Remeasurements comprise gains or losses recorded in the income statement arising from changes in the fair value of commodity contracts and of derivative financial instruments to the extent that hedge accounting is not achieved or is not fully effective. Stranded cost recoveries are costs associated with historical generation investment and related contractual commitments that were not recovered through the sale of those investments. Commentary provided in respect of results after exceptional items, remeasurements and stranded cost recoveries is described as 'statutory'. Further details are provided in note 3 on page 29. A reconciliation of business performance to statutory results is provided in the consolidated income statement on page 21. (7)    'Constant currency basis' refers to the reporting of the actual results against the results for the same period last year which, in respect of any US$ currency denominated activity, have been translated using the average US$ exchange rate for the 6 months ended 30 September 2011, which was $1.64 to GBP1.00. The average rate for the year ended 30 September 2010, was $1.52 to GBP1.00. 
(8)    Post-retirement costs include the cost of pensions and other post employment benefits

Notes to the 2011/12 Half Year Financial Information

1. Basis of preparation and new accounting standards, interpretations and amendments

The half year financial information covers the six month period ended 30 September 2011 and has been prepared under International Financial Reporting Standards (IFRS) as issued by the International Accounting Standards Board (IASB), and IFRS as adopted by the European Union, in accordance with International Accounting Standard 34 'Interim Financial Reporting' and the Disclosure and Transparency Rules of the Financial Services Authority. The half year financial information is unaudited but has been reviewed by the auditors and their report is attached to this document.

The following standards, interpretations and amendments, issued by the IASB and by the IFRS Interpretations Committee (IFRIC), are effective for the year ending 31 March 2012. None of the pronouncements had a material impact on the Company's consolidated results or assets and liabilities for the six month period ended 30 September 2011.

   --      IFRIC 19 on extinguishing financial liabilities with equity instruments 
   --      Amendment to IFRIC 14 on pension minimum funding requirements 
   --      Amendment to IFRS 1 on first time adoption of IFRS 
   --      IAS 24 related party disclosures 
   --      Improvements to IFRS 2010 

The half year financial information does not constitute statutory accounts as defined in Section 434 of the Companies Act 2006. It should be read in conjunction with the statutory accounts for the year ended 31 March 2011, which were prepared in accordance with IFRS as issued by the IASB and as adopted by the European Union, and have been filed with the Registrar of Companies. The auditors' report on these statutory accounts was unqualified and did not contain a statement under Section 498 of the Companies Act 2006.

The half year financial information has been prepared in accordance with the accounting policies expected to be applicable for the year ending 31 March 2012 and consistent with those applied in the preparation of our accounts for the year ended 31 March 2011.

Having made enquiries, the Directors consider that the Company and its subsidiary undertakings have adequate resources to

continue in business for the foreseeable future, and that it is therefore appropriate to adopt the going concern basis in preparing the half year financial information.

Date of approval

This announcement was approved by the Board of Directors on 16 November 2011.

2. Segmental analysis

The Board of Directors is National Grid's chief operating decision making body (as defined by IFRS 8 on operating segments). The segmental analysis is based on the information the Board of Directors uses internally for the purposes of evaluating the performance of operating segments and determining resource allocation between segments. The performance of operating segments is assessed principally on the basis of operating profit before exceptional items, remeasurements and stranded cost recoveries. The following table describes the main activities for each operating segment:

 
 UK Transmission       High voltage electricity transmission networks, 
                        the gas transmission network in Great Britain, 
                        UK liquefied natural gas (LNG) storage activities 
                        and the French electricity interconnector. 
 UK Gas Distribution   Four of the eight regional networks of Great 
                        Britain's gas distribution system. 
 US Regulated          Gas distribution networks, electricity distribution 
                        networks and high voltage electricity transmission 
                        networks in New York and New England and 
                        electricity generation facilities in New 
                        York. 
--------------------  ---------------------------------------------------- 
 

Other activities primarily relate to non-regulated businesses and other commercial operations not included within the above segments, including: UK-based gas and electricity metering activities; UK property management; a UK LNG import terminal; other LNG operations; US unregulated transmission pipelines; US gas fields; together with corporate activities.

Sales between operating segments are priced having regard to the regulatory and legal requirements to which the businesses are subject. The analysis of revenue by geographical area is on the basis of destination. There are no material sales between the UK and US geographical areas.

As a consequence of the introduction of a new operating model, which took effect on 4 April 2011, there has been a corresponding change to our reported segments. The former US Transmission, US Gas Distribution and US Electricity Distribution & Generation segments have been combined and are now reported as 'US Regulated'.

Exceptional items, remeasurements and stranded cost recoveries are items of income and expenditure that, in the judgment of management, should be disclosed separately on the basis that they are material, either by their nature or their size, to an understanding of our financial performance and significantly distort the comparability of financial performance between periods. Remeasurements comprise gains or losses recorded in the income statement arising from changes in the fair value of commodity contracts and of derivative financial instruments to the extent that hedge accounting is not achieved or is not effective. Stranded cost recoveries represent the recovery of historical generation-related costs in the US, related to generation assets that are no longer owned by National Grid. Such costs are being recovered from customers as permitted by regulatory agreements.

3. Exceptional items, remeasurements and stranded cost recoveries continued

1) Restructuring costs for the period include: transformation related initiatives of GBP17m (2010: GBP26m; year ended 31 March 2011: GBP103m); and costs related to the restructuring of our US operations of GBP55m (2010: GBPnil; year ended 31 March 2011: GBP10m) which include severance costs and pension and other post-retirement benefit curtailment gains and losses. For the six months ended 30 September 2010 and the year ended 31 March 2011 restructuring costs also included: costs related to the integration of KeySpan of GBP6m and GBP15m respectively; and a release of GBP39m in both periods of restructuring provisions recognised in prior years.

2) Environmental charges include GBPnil (2010: GBP69m; year ended 31 March 2011: GBP70m) and GBP37m (2010: GBP6m; year ended 31 March 2011: GBP58m) related to specific exposures in the UK and US respectively. Costs incurred with respect to US environmental provisions are substantially recoverable from customers.

3) During the period we recognised a net credit of GBP19m in relation to disposals of businesses made in prior periods representing additional charges and release of various unutilised provisions. During the year ended 31 March 2011 we sold three wholly owned subsidiaries and an interest in an associate resulting in a gain of GBP15m (six months ended 30 September 2010: GBP19m net gain).

   4)   Impairment charges and related costs for the year ended 31 March 2011 included: 

- a charge of GBP49m relating to our investment in Blue-NG, a joint venture investing in combined heat and power generation. The charge comprised an impairment of the carrying value of the investment together with committed funding and associated exit costs (six months ended 30 September 2010: GBP58m);

- an impairment charge of GBP34m against the carrying value of the goodwill relating to our US companies in New Hampshire, following our announcement in December 2010 of the proposed sale of these businesses; and

- a charge of GBP50m relating to our US generation assets for impairment and associated decommissioning.

5) Other exceptional charges for the period include an amortisation charge of GBP3m (2010: GBP3m; year ended 31 March 2011: GBP7m) in relation to acquisition-related intangibles. In addition the charge for the year ended 31 March 2011 included a GBP8m penalty levied by Ofgem on our UK gas distribution business.

6) Remeasurements - commodity contracts represent mark-to-market movements on certain physical and financial commodity contract obligations in the US. These contracts primarily relate to the forward purchase of energy for supply to customers, or to the economic hedging thereof, that are required to be measured at fair value and that do not qualify for hedge accounting. Under the existing rate plans in the US, commodity costs are recoverable from customers although the timing of recovery may differ from the pattern of costs incurred. These movements are comprised of those affecting operating profit which are based on the change in the commodity contract liability and those recorded in finance costs as a result of the time value of money.

7) Stranded cost recoveries include the recovery of some of our historical investments in generating plants that were divested as part of the restructuring and wholesale power deregulation process in New England and New York during the 1990s. Stranded cost recoveries on a pre-tax basis consist of revenue of GBP170m (2010: GBP176m; year ended 31 March 2011: GBP355m) and operating costs of GBP3m (2010: GBP4m; year ended 31 March 2011: GBP7m).

8) During the year ended 31 March 2011 we reached agreement with the US tax authorities on the settlement of pre-acquisition tax liabilities which resulted in the repayment of tax and interest accruing.

9) Debt redemption costs for the year ended 31 March 2011 of GBP73m (six months ended 30 September 2010: GBP57m) represented costs arising from our debt repurchase programme, undertaken primarily in the first half of last year, to manage our cash resources efficiently following the rights issue.

10) Remeasurements - net gains and losses on derivative financial instruments comprise gains and losses arising on derivative financial instruments reported in the income statement. These exclude gains and losses for which hedge accounting has been effective, which have been recognised directly in other comprehensive income or which are offset by adjustments to the carrying value of debt. The tax credit on remeasurements includes GBPnil (2010: GBPnil; year ended 31 March 2011: GBP104m credit) in respect of prior years.

11) The exceptional tax credit arises from a reduction in the UK corporation tax rate from 26% to 25% included and enacted in the Finance Act 2011 and applicable from 1 April 2012. Other UK tax legislation also reduced the UK corporation tax rate in the prior periods (2010: from 28% to 27%; year ended 31 March 2011: from 28% to 26%). These reductions have resulted in a decrease in deferred tax liabilities.

12) The exceptional tax credit for the year ended 31 March 2011 primarily arose from a settlement of pre-acquisition tax liabilities with the US tax authorities.

5. Taxation

The tax charge for the period, excluding tax on exceptional items, remeasurements and stranded cost recoveries is GBP254m (2010: GBP279m; year ended 31 March 2011: GBP722m). The effective tax rate of 26.7% (2010: 29.7%) for the period is based on the best estimate of the weighted average annual income tax rate by jurisdiction expected for the full year. The current period rate reflects the varied seasonality of earnings in the US. For the full year we expect the group effective tax rate to be approximately 29%. The effective tax rate for the year ended 31 March 2011 was 29.2%.

Save as disclosed below, there have been no significant changes in relation to litigation and claims, from the position reported on page 152 of our Annual Report and Accounts 2010/11.

In respect of the Gas Distribution mains replacement investigation, following the receipt of the Final Penalty Notice on 13 May 2011, we paid the penalty in full on 20 June, within the relevant deadline.

In respect of the KeySpan class actions, the claim dismissed in the federal court on 22 March 2011 was appealed by the plaintiff on 3 June in the Second Circuit U.S. Court of Appeals. In respect of the claim in the New York State Court our initial application for dismissal was denied on procedural grounds; we are filing a notice of appeal against this and the claim will enter a customary procedural discovery phase pending the decision on

appeal.   We continue to believe that both complaints and their allegations are without merit. 

As reported in our 2010/11 Annual Report and Accounts, the severe winter weather significantly increased emergency workload and hindered our engineers' travel. As a result we fell short in six of our eight standards of service for gas escapes where we are required to attend 97% of the escapes between one and two hours of the report. As a result, in October Ofgem announced that it will investigate whether we complied with the emergency standards included in our gas transporter licence.

11. Businesses held for sale

As at 31 March 2011, our EnergyNorth gas business and Granite State electricity business in New Hampshire were classified as businesses held for sale. As at 30 September 2011, these businesses continued to be classified as held for sale as they are expected to be disposed during the year ending 31 March 2012. As at 30 September 2011, Seneca-Upshur our oil and gas exploration business in West Virginia and Pennsylvania; and OnStream our non-regulated metering business in the UK were also reclassified as businesses held for sale and were sold on 3 October 2011 and 24 October 2011 respectively.

The results of these businesses have not been separately disclosed from those of continuing operations as they do not constitute a separate major line of business or geographical area of National Grid's operations.

12. Exchange rates

The consolidated results are affected by the exchange rates used to translate the results of our US operations and US dollar transactions. The US dollar to pound sterling exchange rates used were:

The Directors of National Grid plc are as listed in the National Grid plc Annual Report for the year ended 31 March 2011 with the exception of the following changes to the Board:

Independent review report to National Grid plc

Introduction

We have been engaged by the Company to review the condensed set of financial statements in the half year financial information for the six months ended 30 September 2011, which comprises the consolidated income statement, statement of comprehensive income, balance sheet, statement of changes in equity, cash flow statement and related notes. We have read the other information contained in the half year financial information and considered whether it contains any apparent misstatements or material inconsistencies with the information in the condensed set of financial statements.

Directors' responsibilities

The half year financial information is the responsibility of, and has been approved by, the directors. The directors are responsible for preparing the half year financial information in accordance with the Disclosure and Transparency Rules of the United Kingdom's Financial Services Authority.

As disclosed in note 1, the annual financial statements of the group are prepared in accordance with IFRSs as adopted by the European Union. The condensed set of financial statements included in this half year financial information has been prepared in accordance with International Accounting Standard 34, "Interim Financial Reporting", as adopted by the European Union.

The maintenance and integrity of the National Grid Plc website is the responsibility of the directors; the work carried out by the auditors does not involve consideration of these matters and, accordingly, the auditors accept no responsibility for any changes that may have occurred to the financial statements since they were initially presented on the website.

Legislation in the United Kingdom governing the preparation and dissemination of financial statements may differ from legislation in other jurisdictions.

Our responsibility

Our responsibility is to express to the Company a conclusion on the condensed set of financial statements in the half year financial information based on our review. This report, including the conclusion, has been prepared for and only for the Company for the purpose of the Disclosure and Transparency Rules of the Financial Services Authority and for no other purpose. We do not, in producing this report, accept or assume responsibility for any other purpose or to any other person to whom this report is shown or into whose hands it may come save where expressly agreed by our prior consent in writing.

Scope of review

We conducted our review in accordance with International Standard on Review Engagements (UK and Ireland) 2410, 'Review of Interim Financial Information Performed by the Independent Auditor of the Entity' issued by the Auditing Practices Board for use in the United Kingdom. A review of interim financial information consists of making enquiries, primarily of persons responsible for financial and accounting matters, and applying analytical and other review procedures. A review is substantially less in scope than an audit conducted in accordance with International Standards on Auditing (UK and Ireland) and consequently does not enable us to obtain assurance that we would become aware of all significant matters that might be identified in an audit. Accordingly, we do not express an audit opinion.

Conclusion

Based on our review, nothing has come to our attention that causes us to believe that the condensed set of financial statements in the half year financial information for the six months ended 30 September 2011 is not prepared, in all material respects, in accordance with International Accounting Standard 34 as adopted by the European Union and the Disclosure and Transparency Rules of the United Kingdom's Financial Services Authority.
