PG&E Announces 250 MW SPWR Power Plant

Two Large Solar Plants Planned in California Companies will build two solar power plants in California that together will put out more than 12 times as much electricity as the largest such plant today, the latest indication that solar energy is starting to achieve significant scale.

Here Comes the Sun Power Pacific Gas and Electric Co. announced plans Thursday to buy 800 megawatts of photovoltaic solar power from two Bay Area companies - a giant deal that would provide enough electricity to power 239,000 homes and would create the country's first utilityscale photovoltaic plants.

PG&E Announces Two Huge Solar Deals SunPower, Optisolar Plan Nation’s Biggest Plants in San Luis Obispo County

PG&E Orders Photovoltaic Plant PG&E, a California power company, has placed an order for what are believed to be the world’s two biggest photovoltaic solar farms, giving a strong endorsement to a technology that few power generators have yet considered to be ready for utility-scale use.

For more than a year, San Jose's SunPower has been touting a 14-megawatt photo-voltaic solar array at Nellis Air Force Base in Las Vegas as the largest in the nation. That's about to change in a big way. Pacific Gas & Electric announced two deals Thursday that will result in 800 megawatts of power from massive facilities using PV panels — enough to power nearly a quarter-million homes, according to the utility.

Why Combine Energy Efficiency and Solar? Electric Rate Escalation: Rates are rising faster than inflation

Carbon Neutrality: Combining is a great path to carbon neutral

Cost Reduction: Reduce Peak Demand, total usage and rate fit Increased Energy Hedge: Rates can be unpredictable - lock in a higher percent of your load from PV by doing EE Leverage a Single Project: Capture the benefits of reducing emergency expenses and improving quality and control LEED, ZEB, and Best Practices: Advance your company’s standards 22
