said Monday that it plans to invest more than $3 billion in a coal-fired power complex and transmission network in eastern Nevada.

Sierra, the holding company for Nevada and Sierra Pacific Power Cos., plans to develop two 750-megawatt units, with the first unit becoming operational during 2011 and the second within three years. The power complex, the company said, provides for expansion through two 500-megawatt coal gasification units when such technology becomes commercially viable.

The transmission network will also allow power generated by renewable sources in the state to be transported.

In December 2005, subsidiary Sierra Pacific Power Co. received clearance from the state regulator for the construction of a 514-megawatt natural gas power plant at an estimated cost of around $420 million.
