San Diego Gas & Electric (SDG&E) to Expand Use of Biomass Energy

http://www.renewableaccess.com/rea/news/story?id=48931

San Diego Gas & Electric (SDG&E) signed a supply contract with Envirepel Energy, Inc. for renewable, biomass energy that will be online by October 2007.

SDG&E also reported that it has received nearly 5,000 megawatts (MW) of renewable-energy-supply proposals in response to the utility's most recent renewable Request for Offers (RFO) solicitation that ended May 30, 2007. Envirepel's agreement is the result of an earlier competitive solicitation.

The nearly 5,000 MW proposed in the most recent RFO represents a mixture of renewable energy, including about 2000 MW of wind, 2,700 MW of solar, and 300 MW of geothermal, biomass and landfill gas. Several of the proposals submitted would require the addition of new transmission infrastructure to deliver energy to San Diego customers.

"Developers are signaling their willingness to build these renewable projects," said Debra L. Reed, president and chief executive officer for SDG&E. "We are committed to providing the transmission pathway necessary to ensure renewable energy from any of the projects developed reaches San Diego." SDG&E is more than halfway toward meeting its 2010 goal with approximately 12 percent of its future energy supply under contract to be delivered from renewable sources.

amounts of sewage for methane (aka "natural gas") production and subsequent electricity generation rather than sending it, partially treated, into waterways and the sea?

The waste of a valuable resource is criminal.

the investment would pay for itself and reduce local tax burdens.

wrong for a switch of that magnitude??

Current processes, IIRC, rely upon oxidative breakdown of the nitrogenous wastes, whereas to get methane you need anaerobic processes.
