Sierra Pacific Resources subsidiaries Nevada Power and Sierra Pacific
Power are seeking proposals to help them meet Nevada's renewable portfolio
standard.

The utilities are interested in buying renewable projects or entering
into power purchase agreements with developers, according to the request for
proposals. The companies said they will consider three types of asset
purchases: buying the development rights to a project, buying a turnkey
project and entering into a PPA with an option to buy the plant. Potential
projects must be at least 1 MW and online by 2010, the RFP said.

Projects must be in Nevada, while PPAs can be for up to 20 years. Bids
are due November 13 and the utilities hope to execute contracts by the summer.

The utilities face an RPS that climbs to 20% by 2015. At the same time
Nevada is growing rapidly, which is driving up the amount of renewable energy
needed by the utilities.
