Global BESS Capacity Exceeds 800 GWh by 2028
This prediction targets a total global installed capacity of **Battery Energy Storage Systems (BESS)** exceeding $800$ GWh before the end of 2028. This requires a Compound Annual Growth Rate (CAGR) of over $50\%$ from the estimated 2025 capacity.
Grid Decarbonization Mandates
The high **'Yes'** vote is supported by consensus forecasts from leading energy agencies. The need to integrate variable renewable energy (solar and wind) into the grid requires massive storage. Driven by regulatory mandates in China, the EU, and the US (particularly California and Texas), the investment in BESS is non-linear. BloombergNEF and other analysts project that given the cost decline and project pipeline, the $800$ GWh milestone by 2028 is a highly achievable target.
