Xcel Energy Solicits Bids for Colorado's Largest Solar Facility

03/30/2006

DENVER--(BUSINESS WIRE)--March 30, 2006--Xcel Energy today began soliciting bids for a photovoltaic (PV) solar power plant that will be located in Colorado's San Luis Valley to produce about 13,700-megawatt hours of electricity a year.

Today's announcement coincides with the company's solicitation of request for proposals for bidders to build, own and operate the plant. The solicitation may be viewed at www.xcelenergy.com/rfp.

The PV facility will benefit Colorado by using the sun to generate electricity for homes and businesses. It will produce no air emissions and use no water on site. When complete, it could supply power for as many as 1,800 homes. The company anticipates construction will begin in 2006 and be completed by the end of 2007.

"This facility will put the San Luis Valley on the map for solar power production and will also add significantly to the region's economy," said Pat Vincent, president and CEO, Public Service Company of Colorado, an Xcel Energy company. "This PV plant combined with Xcel Energy's Solar Rebate program will help bring us closer to meeting the state's Renewable Energy Standard."

This project and the rebates being offered for on-site solar installations will be paid for out of funds approved by the voters when they passed Amendment 37.
