San Diego Gas & Electric (SDG&E) reported to the California Public Utilities Commission (CPUC) on March 1 that 20.8 percent of the energy delivered to its retail customers in 2011 was provided by renewable energy sources, such as wind, geothermal, biomass, hydroelectric and solar facilities. Surpassing the 20 percent mark represents SDG&E’s largest single year increase in renewable power in proportion to overall power sales – 9 percent over the utility’s 2010 results.
The 9 percent increase reported to the state regulators was due to the delivery of power from agreements involving wind and geothermal energy, the utility says.
Of the overall 20.8 percent in retail renewable sales, geothermal, biomass, biogas, and solar projects accounted for almost 40 percent of the power. About 60 percent of this total can be attributed to wind power.
In 2011, SDG&E signed 17 new power contracts with mostly solar and wind energy sources, representing 1,482 MW. In 2012, SDG&E expects five new renewable energy projects within its energy portfolio will become operational.
