Substation Upgrades Bring Renewables Home

摘要

SDG&E upgrades transmission substations and switchyards to meet California Renewables Portfolio Standard. To meet the state-mandated California Renewables Portfolio Standard, San Diego Gas & Electric (SDG&E) constructed, energized and put into service a Sunrise Powerlink project connecting San Diego, California, U.S., to the renewables-rich Imperial County, California. The standard requires investor-owned utilities in California to increase procurement of renewable energy resources (RERs) to 33% by 2020.
