Lithium battery overcapacity leads to solar container development

Fleets of lithium-ion battery units now absorb surplus solar power at midday and release it during evening peaks when electricity prices soar. In the five years since, battery storage capacity across California has surged more than 3,000 percent – from roughly 500 megawatts in 2020 to about 15,700 megawatts by mid-2025 – transforming how the grid manages supply and demand. A particular focus of attention on the overcapacity debate has been China’s “new three” sectors of solar power, electric vehicles (EVs) and lithium batteries – products that are also central to China’s and the world’s. For PVs, leading Chinese players have sought to bolster their market share by rapidly expanding production capacity. Welcome to the paradoxical world of energy storage battery project overcapacity – where green ambitions crash into economic realities.
