China's Coal Comeback: 30 GW Added, Record Clean Energy Unused, and What It Means for You

Beijing, China, MMN Correspondent: What happens when a nation builds record wind and solar capacity and adds 30 gigawatts of coal in the same six months? China just showed us.

China added 30 gigawatts of new coal capacity in the first half of 2026 and retired 2.7 gigawatts. Coal-fired generation rose 3 percent compared with the first half of 2025. That followed a modest decline across 2025. All of this took place during a stretch when wind and solar installations reached record highs.

The numbers come from a new report by the Centre for Research on Energy and Clean Air and Global Energy Monitor. Renewable capacity grew faster than ever in the same period. The challenge is that the grid could not absorb all of that clean power. Curtailment, the intentional reduction of renewable output, rose roughly 50 percent year on year. The unused electricity equaled Indonesia's entire annual electricity output.

This expansion did not appear overnight. A wave of coal plant approvals began in 2021 after high coal prices caused blackouts and factory shutdowns in about 20 provinces. Local governments fast-tracked projects to protect against future shortages. That wave is now showing up in real capacity.

The report also notes that another 274 gigawatts of coal capacity is under construction or permitted. That equals about one fifth of China's existing coal fleet. These projects are largely locked in for years, no matter how fast renewable energy scales up.

Qi Qin, the report's author, called the situation a climate concern. New coal plants need to earn revenue and run for decades. That can keep older units active for longer and reduce the space available for cleaner energy on the grid.

In parallel, Beijing's policy language is evolving. Recent documents call for reasonable control of both coal capacity and the amount of electricity generated from coal. The latest five-year plan targets a 17 percent cut in carbon intensity, or emissions per unit of GDP, between 2026 and 2030, with net zero by 2060. Qi Qin notes a gap between that direction and the reality on the ground, where coal remains protected.

The reason coal keeps its position is structural. Coal generators must sign long-term contracts covering 70 percent of their previous year's output. The contracts give them predictable prices and utilization rates. In practice, that shields coal from direct competition with cheaper renewable power.

China has also introduced capacity payments this year. These payments reward coal plants for being available to generate, even when they are not running. Each mechanism can make sense for grid reliability. Together, they make it difficult for renewables to take priority. When wind and solar output is high, coal operators have little reason to reduce their own generation and no rule requiring them to do so.

The report suggests a different set of options. It proposes lowering or suspending coal contract minimums in provinces with high clean energy curtailment or zero or negative electricity prices. This would let coal transition into a flexible backup role. It also calls for a pause on new coal permits and a review of approved projects. On the grid side, the authors recommend more investment in transmission lines, cross-provincial power trade, and storage. Those steps can strengthen reliability and support clean energy at the same time.

The timing matters far beyond China. Its energy choices affect the global goal of limiting warming to 1.5 degrees Celsius. The report is essentially a practical guide for aligning infrastructure and policy with climate targets. The technology for a cleaner grid exists. The market design now needs to evolve.

For anyone following the transition, the message is clear. Building more wind and solar farms is only part of the equation. The grid, the contracts, and the incentives around them must change in parallel. That is the real opportunity here. With the right adjustments, coal can fade into a backup role and wind and solar can take the lead.
