China Has Too Much Solar Power for Its Grid to Use

China has invested heavily in solar and wind power generation. However, parts of its electricity grid struggle to handle all the renewable energy these sources could produce. In the first half of 2026, China had to curtail some wind and solar power generation.
The exact amount of curtailment is debated. Official Chinese data shows lower curtailment rates than independent research groups estimate. Despite this disagreement, both sources highlight the same issue: renewable energy projects are expanding faster than transmission infrastructure, storage systems, and other grid components.
Solar power requires transmission lines to transport electricity and sometimes battery storage before reaching consumers. When supply exceeds the capacity of these systems, available renewable energy goes unused. China is not unique in facing this challenge. Australia, Japan, and India also struggle to integrate growing amounts of solar and wind power into their grids. Building renewable energy capacity is essential, but upgrading grids, storage, and management systems must keep pace.
