Chilean electricity distributor Empresas Emel SA (EMEL.SN) has awarded power generator Empresa Electrica del Norte Grande SA (EDELNOR.SN) a 14-year contract worth about $3 billion to supply its distribution subsidiaries in northern Chile from 2012 to 2026.

Edelnor will supply Emel's subsidiaries Empresa Electrica de Arica SA, or Emelari; Empresa Electrica de Iquique SA, or Eliqsa; and Empresa Electrica de Antofagasta SA, or Elecda, with a total 1,800 gigawatt hours of energy annually from 2012, gradually increasing to 2,300GWh by 2016 and remaining at that level until 2026.

Edelnor submitted the lowest economic bid - $89.99 per megawatt hour indexed 60% to the monthly average Henry Hub liquefied-natural-gas price and 40% to the U.S. consumer price index - for all 23 sub-blocks of energy supplies on offer.

The generator linked its bid to the LNG price because it is controlled by state copper miner Corporacion Nacional del Cobre de Chile and Belgian-French energy giant Suez (SZE.FR), which are developing a project to import LNG to northern Chile. The Mejillones regasification terminal is scheduled to start receiving LNG in early 2010.

Edelnor's 250 megawatt CTM3 unit at its Mejillones thermoelectric complex is currently operating with diesel in the absence of Argentine gas supplies, but will switch back to burning natural gas once LNG arrives. Argentina began restricting gas exports to Chile in 2004, forcing power generators to switch to diesel.

Edelnor has told the local securities regulator that most of the energy supplied to Emel's clients will be generated using regasified LNG from Mejillones.

But it does not need to burn imported gas to supply Emel. Plants in northern Chile's Sistema Interconectado Norte Grande, or SING, grid are dispatched in order of the lowest marginal cost, which means that coal-fired plants, which are cheaper to run than plants using LNG, would be dispatched before Edelnor's CTM3 plant.

Edelnor's CTM1 and CTM2 plants burn coal and there are several new coal projects in construction in the SING, so it is likely CTM3 would act as back-up supply while most of the energy would come from coal generation, said Jorge Donoso, an analyst with brokerage LarrainVial.

"Either way, whether Edelnor generates with LNG or buys cheaper power on the spot market, it is good business for Edelnor," Donoso told Dow Jones.

Moreover, Edelnor does not have to make any new investments to meet its contract obligations. "It can switch over its CTM3 plant [to gas], but it doesn't have to build any new ones," said Donoso.

The contract will double Edelnor's capacity and energy sales with a total contracted capacity of 680MW from 2012, the company said.

"It's good for Edelnor to secure its supply volumes and operating income going forward," said Adolfo Moreno, a utilities analyst at IM Trust.

Edelnor's bid came in well below the maximum price set by Emel for the tender, which was $138.22/MWh, and below those of its rival generators.

AES Gener (GENER.SN), owned by AES Corp. (AES) of the U.S., bid $105/MWh for one sub-block indexed 65% to the U.S. CPI and 35% to the monthly average coal price.

The other bidder, GasAtacama Chile SA bid between $105 and $138 for four sub-blocks indexed 90% to the monthly average diesel price and 10% to the U.S. CPI.

GasAtacama is controlled by Chilean generator Empresa Nacional de Electricidad SA, or Endesa (EOC) and Latin American private equity fund Southern Cross.

"We are happy, the tender attracted great interest in the market and we received bids that exceeded by a large amount the energy required," said Emel's general manager, Cristian Saphores.

Energy Minister Marcelo Tokman also applauded the result of the tender, highlighting that energy supplies are now assured in Chile's central and northern grids for the next decade.

"This is a sign that the country has entered another stage of energy development," Tokman told reporters Thursday.

As to how the deal will affect consumers in the SING grid, the price offered by Edelnor is lower than consumers currently pay for power, which is over $100/MWh, but it depends on the future Henry Hub gas price, which is linked to the oil price, Donoso said.

According to its Web site, Emel supplies power to 575,634 clients in northern Chile through 895 kilometers of transmission and sub-transmission lines.

Edelnor operates the 591MW Mejillones thermoelectric complex in the SING as well as several smaller diesel plants and one hydroelectric plant.

Edelnor posted net profit of $129 million in 2008 with profit expected to fall 24% to $98 million in 2009 due to lower energy prices in the SING as a result of lower fuel prices, according to LarrainVial

As a result of the contract, LarrainVial changed its recommendation for Edelnor's shares to attractive from not attractive.

Edelnor's shares were trading up 3.4% to CLP827.00 midday Thursday, while the Ipsa blue chip index was up 0.6% overall. Edelnor has traded at a 52-week high of CLP799.91 and a low of CLP401.10.
