China’s renewable power output is being held back by inadequate grid infrastructure, raising curtailment risks
Executive summary: China’s solar and wind power generation is increasingly curtailed due to grid bottlenecks, according to a Handelsblatt‑cited analysis. Curtailment reduces the economic returns of renewable projects and threatens the country’s ability to meet its 2030 carbon‑neutral goals.
Who is involved: Chinese renewable developers, state grid operators, and policymakers overseeing the 14th Five‑Year Plan.
Likely next: Grid operators are expected to announce new transmission line projects and storage pilots in the second half of 2026 to alleviate congestion.
The Handelsblatt report cites an analysis showing that despite China’s world‑leading solar and wind installations, a growing share of that generation is lost because the transmission network cannot accommodate the output. The bottleneck stems from insufficient inter‑regional lines and limited storage capacity, which together force operators to curtail renewable output. Analysts warn that unless grid expansion accelerates, the country’s clean‑energy targets could be undermined and investment returns weakened.
