Solar Siting Surveys

The Clean Coalition conducts Solar Siting Surveys to help utilities, cities, and communities assess the potential for local solar generation. Below are our publicly available Solar Siting Surveys.

San Diego Solar Siting Survey

The Clean Coalition completed a Solar Siting Survey for the City of San Diego, as part of the San Diego Solar Energy Innovation Network (SD SEIN) Initiative. The San Diego Solar Siting Survey identified approximately 500 megawatts (MWac) of technical solar siting potential for large commercial-scale solar on built environments within the City. The survey pinpointed the location and estimated project sizing for over 120 prospective solar sites that could host solar PV systems of at least 1 MWac. While a portion of the solar siting potential is on large rooftops, more than 75% is on parking lots and parking structures, which are often overlooked as siting opportunities for clean local energy. In total, this survey identified enough local solar capacity to fulfill the average power needs of about 500,000 homes during peak solar production hours. Learn more about our San Diego Solar Siting Survey and see the results.

East Bay Community Energy Solar Siting Survey

The Clean Coalition completed a Solar Siting Survey for East Bay Community Energy’s (EBCE) Local Business Development Plan. The Local Development Business Plan is intended to develop a comprehensive framework for accelerating the development of clean energy assets within Alameda County in California. It will include details on how EBCE’s Community Choice program can contribute to fostering local economic benefits, such as job creation and community energy programs, plus identify opportunities for clean local energy development. The Clean Coalition’s EBCE Solar Siting Survey identified over 650 megawatts (MW) of technical solar photovoltaic (PV) siting potential on over 250 discrete sites — enough to power 165,000 homes. Each site identified has the potential to host at least 1 MW on rooftops, parking lots, and parking structures located at the site. Learn more about our EBCE Solar Siting Survey and see the results.

Peninsula Advanced Energy Community Solar Siting Survey

As part of the Peninsula Advanced Energy Community (PAEC), an initiative designed to streamline policies and showcase projects that facilitate local renewables and other advanced energy solutions, the Clean Coalition conducted a Solar Siting Survey to assess the potential for commercial solar PV in southern San Mateo County. The PAEC Solar Siting Survey evaluated thousands of potential locations — based on site characteristics, existing loads, and grid infrastructure — to identify those in built environments that are best suited for a solar PV installation of at least 100 kW. In total, this Solar Siting Survey identified over 65 MW of technical potential for commercial solar installations within the PAEC region. Many more siting opportunities of different capacities in the PAEC region are coming soon. Learn more about our PAEC Solar Siting Survey and see the results.

SCE Preferred Resources Pilot Solar Siting Survey

The PRP Solar Siting Survey highlights significant levels of local solar PV energy that can be generated within an area in southern and central Orange County. The grid area assessed by the survey comprises the Preferred Resources Pilot (PRP), an effort by Southern California Edison (SCE) to study and demonstrate how distributed energy resources, including local solar PV, may support local reliability needs. The PRP Solar Siting Survey identified over 160 MW of technical potential for large commercial solar installations 500 kW and larger within the PRP grid area. Learn more about our PRP Solar Siting Survey and see the results.
