Satcon Selected for 5 Megawatt CalRENEW-1 Solar Farm

Satcon Technology Corporation (NASDAQ CM: SATC), a leading provider of utility scale power solutions for the renewable energy market, today announced that it has been selected for the CalRENEW-1 installation, the first utility-scale photovoltaic solar farm to be approved by the California Public Utilities Commission under the state’s Renewable Portfolio Standard program.

The 5 megawatt AC facility, located in Mendota, CA, will utilize five, one megawatt Prism solutions, Satcon’s fully integrated utility platform that comes complete with factory integrated medium voltage transformers, switchgear, and electronics. Introduced in June of 2009, Prism is the industry’s most advanced 1 megawatt solar PV power conversion solution, and is built on the market leading PowerGate 500 kW inverter line, which has been installed on over 170 megawatts of large scale solar power plants since 2005. Each 1 MW Prism solution is delivered complete in an all-climate outdoor enclosure and ready to connect to the PV array and utility grid, enabling rapid installation through a modular prepackaged design.

CalRENEW-1 will be one of the most advanced photovoltaic solar facilities in the world. The 5 MW plant will generate zero emission electricity for sale to Pacific Gas & Electric under a long term power purchase agreement.

“We are excited to be a part of the CalRENEW-1 project, which clearly demonstrates the increased role of large scale solar power production as an integral part of tomorrow’s energy network," said Steve Rhoades, President and Chief Executive Officer of Satcon Technology. “Our continued focus on developing the highest performing, most reliable, and most advanced utility ready solar PV inverter systems allow us to deliver the solutions that enable utilities to effectively integrate solar power as a secure and cost effective renewable energy source.”
