Puget Sound Energy seeks all-sources power, including hydro

Puget Sound Energy seeks proposals from power producers, marketers, and power plant developers to supply up to 1,340 average MW 2015. Bids are due Feb. 29.

All types of power-generating fuels or technologies are eligible for consideration, PSE said. The utility said it would consider various contract arrangements, such as investment in existing power plants, ownership of new power plants, and long-term power purchases.

To meet a 2006 voter mandate of Washington State Initiative 937, PSE noted it would need to acquire about 1,000 MW of renewable power by 2020. (HNN 11/14/06) The initiative requires utilities to acquire 15 percent of their energy from new renewable sources, which may include incremental electricity from efficiency improvements at regional utility-owned hydro projects and irrigation pipes and canals.

PSE, a subsidiary of Puget Energy, said customer growth and the expiration of large purchased-power contracts in coming years will require the utility to acquire a large amount of new power supplies. PSE estimates it will need more than 1,600 aMW of new electricity in the next decade, and more than 2,600 aMW by 2025, roughly equivalent to the power demand of two cities the size of Seattle.

The Jan. 11 request for proposals can be obtained from the utility’s Internet site at www.pse.com/energyEnvironment/energysupply/Pages/pse2008RFP.aspx. A conference for prospective bidders is planned Jan. 23. For information, contact Sheri Maynard by e-mail at sheri.maynard@pse.com.
