More Green Power For San Diego Utility

Driven by California’s renewable portfolio standardSan Diego Gas and Electric (SDGE) is having a big year in bringing clean energy into its portfolio. The company, which had already added some 1,200 megawatts (MWs) of capacity since January 1, recently announced two more contracts that will give it an additional 190 MWs of green power.

The new deals consist of a 25-year power purchase agreement with Solar Gen 2 for up to 150 MWs of solar power, and a one-year contract to buy up to 40 MWs of geothermal power from Silicon Valley Power.

Solar Gen II’s development will generate up to 150 MWs using photovoltaic panels with single-axis tracking. Plans call for the project to be completed in three 50-MW phases at separate sites in California’s Imperial Valley. The panels are expected to generate 361 gigawatt-hours (GWhs) each year during the length of the contract, amounting to nearly 2 percent of SDGE’s total renewable energy portfolio. The first phase of the project is slated for completion next summer.

Silicon Valley Power has already begun delivering geothermal power from fields it owns in Northern California. The 350 GWhs of steam energy over the course of the one-year contract. For the year, the contract will provide around 1 percent of SDGE’s total portfolio.
