China’s clean-power curtailment highlights global grid bottlenecks

Curtailment occurs when wind or solar generation is available but cannot be accepted because networks, dispatch rules or demand flexibility are insufficient. China’s 360 TWh first-half curtailment figure is large enough to show that capacity additions alone do not guarantee usable clean electricity. For global solar markets, the lesson is that transmission, storage, flexible demand and interconnection reform must scale alongside PV and wind deployment.
