Solar and Storage Projects in the US Making Big Moves

Several solar and storage projects across the United States are making significant advancements. The Westlands Water District Board of Directors have given their approval to the Valley Clean Infrastructure Plan’s environmental review, which is set to be the largest solar farm in the country. The state of Arizona is welcoming four new solar projects brought by SOLON Corporation and Onyx Renewables, while Recurrent Energy has sold its 200 MWh battery energy storage system project to Texas-based Hunt Energy Network. Furthermore, Meta’s American data center operations are receiving support from MN8 Energy’s solar project in Pennsylvania. Other notable movements in the field include PowerBank, Arevon and OCI Energy securing project financing, Empact Technologies and Sabanci Renewables collaborating for tax credit compliance, and Willdan Group partnering with Mt. San Antonio College for solar power additions and infrastructure enhancements.

Westlands Water District Board of Directors Approves Valley Clean Infrastructure Plan

The Westlands Water District Board of Directors have certified the environmental review of the Valley Clean Infrastructure Plan (VCIP), which is projected to be the biggest solar farm in the United States. The VCIP is expected to introduce more than 20 GW of solar energy and an additional 20 GW of energy storage in California. This could drastically alter California’s energy grid. According to representatives from Golden State Clean Energy (GSCE), the project will incorporate a 500 kV transmission system to carry the clean energy onto the existing California grid. GSCE also mentioned that the project will save ratepayers approximately $9 billion by 2050.
