LA County Community Solar Opportunity Map
The solar opportunity map is a web tool built to assist community-based organizations to access data necessary to identify high potential sites for community solar or resiliency centers within LA County.
The California Center for Sustainable Communities at UCLA has developed this tool as an interactive, web-based platform which aids in locating, filtering, and prioritizing sites on publicly-owned properties throughout the county that can host rooftop and/or carport canopy solar PV systems. Installing additional distributed solar PV can help improve local energy system resilience, advance community-scale Zero Net Energy goals, and enhance grid reliability.
Community solar enables renters, as well as homeowners who are unable to install solar, to purchase power generated by local PV systems, helping to overcome some of the barriers to under-served communities benefiting from the clean energy transition. Resiliency centers serve community members during grid outages by providing cool (or warm) spaces, charging points for critical electronics, wifi connectivity, and other resources. Our aim is to support community-based organizations and local governments accelerate their planning and implementation efforts to bring community solar and resiliency centers to their constituents.
The map uses cutting-edge data and analytics to show community assets that may be prime locations for installing solar. This capability has not been publicly available to date. The tool focuses on the service territory of the regional investor-owned electric utility in LA County, Southern California Edison. The tool supports many types of energy systems planning activities, including siting DERs and electric vehicle charging stations, understanding geographic variations in congestion of local transmission and distribution grid infrastructure, and high-detail areas best poised to achieve ZNE goals.
The tool builds on one of the capstone products of an Advanced Energy Community (AEC) Phase I design grant from the California Energy Commission (CEC). As part of that design process, the AEC project team compiled multiple sources of data for unincorporated communities of Eastern LA County, including Bassett and Avocado Heights, on electricity and natural gas consumption, community characteristics, and existing grid capacity. The planning process devised methods and datasets to support Net Zero Electricity designs in these parts of the county.
This Community Solar Opportunity Map applies the knowledge gained in that work, expands the geographic scale, adds new data, and employs new data integration methods . Funding for this work is provided by a grant from California’s Strategic Growth Council, under the California Climate Investments Initiative.
Specifically, the tool integrates data for:
- Publicly-owned or community-oriented parcel locations,
- Rooftop and parking lot canopy structure solar potentials,
- Community level aggregated electricity consumption from the UCLA Energy Atlas,
- Net solar potential considering historic on-site demand for potential installation sites,
- Detailed grid distribution circuit capacity data published by Southern California Edison (SCE) as part of their Distributed Energy Resources Integration Map (DERiM),
- Socio-demographic information from the U.S. Census’ American Community Survey,
- Data on environmental pollution burdens and other sources of community disadvantage from CalEnviroScreen 3.0
In developing the tool, we devised custom methods to calculate net solar potential within the constraints of available data on grid capacity limitations and operations. The new methods include calculating hourly net solar potential and attributing groups of parcels to local circuits across a vast metropolitan area that comprises nearly 16% of the population of California.
The development of this tool was guided by our project partners, listed below, who provided input on their priorities and goals for the energy transition, and who gave iterative feedback on the tool content, functionality and user interface through meetings and discussions starting in June of 2019.
