California’s single-largest solar energy project is scheduled to come up for a vote next month by the Kern County Planning Commission before going on for final consideration by the Board of Supervisors. Proposed by San Diego-based developer Avantus, the nearly 12,000-acre Buttonbush Solar and Storage project would generate 2 gigawatts of electricity. … [Avantus Vice President of Development Kevin] Brokish noted the project was initiated in 2019 in an area where land is being pulled out of production because of pumping limits imposed by California’s Sustainable Groundwater Management Act.
