The massive volume of discarded electricity could have met the country's entire power demand growth for the first half of 2026, potentially allowing for a reduction in coal consumption. Instead, rising coal-fired generation has created a system-wide oversupply, leading to lower utilization rates for thermal plants and record volumes of wasted clean energy. A report by the Centre for Research on Energy and Clean Air and Global Energy Monitor notes that the rapid addition of coal capacity has exacerbated these grid bottlenecks.
China's Renewable Energy Grid Faces Critical Curtailment Surge
China wasted 360 terawatt-hours of wind and solar energy during the first half of the year, a 49% increase from 2023. This surge in clean power curtailment highlights a growing misalignment between the nation's rapid renewable capacity expansion and the physical limitations of its aging power grid infrastructure.
Analysts at Wood Mackenzie warn that this instability threatens the financial viability of future projects. With wind and solar curtailment rates projected to exceed 5% across dozens of provinces over the next decade, market volatility is becoming a major deterrent for investors. Senior analyst Sharon Feng advises developers to prioritize grid capacity and long-term pricing data over raw installation targets. Without significant upgrades to transmission infrastructure, the gap between renewable potential and actual delivery will likely continue to widen.
