san diego community college district borrego solar power purchase agreement
DESCRIPTION
SDCCD's Green Building Policy requires that 10 percent of a project’s total energy is generated from renewable resources, such as solar energy and thermal energy. Data from the California Center for Sustainable Energy show that San Diego Community College District installations generate more renewable energy than any other higher education institution in SDG&E territory. Of the 7.718 megawatts (MW) installed or pending installation under the California Solar Initiative, SDCCD constitutes 2.367 MW of the total. Combined, installations across the District represent the generation of 4,876,129 kilowatt hours (kWh) of renewable energy each year.TRANSCRIPT
