Lawrence Berkeley National Laboratory

Lawrence Berkeley National Laboratory compiled and synthesized empirical data on the U.S. utility-scale solar sector. The focus is on ground-mounted systems larger than 5MAC, including photovoltaic (PV) standalone and PV+battery hybrid projects (smaller projects are covered in Berkeley Lab’s separate U.S. Distributed Solar and Storage annual data update). Data sources are diverse and include data from the Energy Information Administration (EIA), the Federal Energy Regulatory Commission (FERC), and state agencies. The latest update contains project-level data on 1,760 solar projects installed through 2024. The update includes data synthesis covering: 1. Deployment and Technology Trends 2. Capital Costs (CapEx) and Operation & Maintenance (O&M) Costs 3. Performance (Capacity Factors) 4. Levelized Cost of Energy (LCOE) and Power Purchase Agreement (PPA) Prices 5. Wholesale Market Value and Net Value 6. PV+Battery Hybrid Plants (Deployment, CapEx, LCOE, PPAs) 7. Concentrating Solar Thermal Power (CSP) Plants 8. Capacity in Interconnection Queues
