A key feature of the Capella Solar project is the integration of a 3 MW/1.9 MWh battery energy storage system (BESS). This technology enhances grid stability and ensures a consistent power supply, addressing the intermittency challenges of renewable energy.
[pdf] Spearheaded by Terra-Gen, this behemoth stands in California, USA, as the largest battery storage system worldwide, boasting an impressive 875 MW / 3,287 MWh across 4,600 acres. Launched in 2021, it utilizes 1.9 million solar modules and over 120,000 batteries.
[pdf] $280 - $580 per kWh (installed cost), though of course this will vary from region to region depending on economic levels. For large containerized systems (e.g., 100 kWh or more), the cost can drop to $180 - $300 per kWh.
