Xcel Energy Announces Renewable Energy Project Selections

12/06/2007

MINNEAPOLIS--(BUSINESS WIRE)--

Twenty-two proposed renewable energy projects featuring wind, hydroelectric, solar, biomass and biofuel technologies have been selected to receive nearly $23 million from the Xcel Energy (NYSE:XEL) Renewable Development Fund.

An advisory board with representation from Xcel Energy, environmental groups, Xcel Energy customers and the Prairie Island Indian Community today recommended to the Minnesota Public Utilities Commission that $8,223,922 be awarded to projects for energy production and $14,397,817 for research and development.

Nearly 100 renewable energy proposals were reviewed during the current funding cycle. In previous cycles, more than $52 million has been awarded for renewable energy research and renewable energy production. Currently, more than 23 megawatts of renewable energy are under development from fund initiatives.

"Innovative and new renewable technologies, such as solar and biomass, have trouble competing with conventional energy in the marketplace," said Scott Wilensky, Xcel Energy acting vice president of regulatory and government affairs. "The fund's objective is to remove barriers to entry of new renewable energy technologies by funding research on emerging technologies and supporting development of renewable energy projects."

Money for the Renewable Development Fund, which was created in 1999, comes from Xcel Energy customers. Each year the company transfers $16 million to the fund in accordance with state statute. Owners of energy production projects sell the energy to Xcel Energy or use the energy themselves. All selected projects are subject to final approval by the Minnesota Public Utilities Commission.

"The Renewable Development Fund provides research support for marketable advancement of innovative renewable energy and environmental technologies that will benefit Minnesota customers as well as promote renewable energy within the region, nationally, and worldwide," said Bill Grant, associate executive director, Izaak Walton League, and Renewable Development Fund advisory board member.

"This round of grants appropriately focuses on the goal of making solar and biomass resources more cost-effectively available for Xcel Energy customers, which is entirely consistent with our state energy policy goals," said Mike Bull, assistant commissioner of renewable development and advanced technologies, Minnesota Department of Commerce, and Renewable Development Fund advisory board member.
