Wind and solar power goes to waste in China due to poor integration with coal and nuclear base-load

China’s renewable energy expansion is not the clean energy revolution it appears to be. Behind the headlines of record-breaking solar panel installations and towering wind turbines lies a troubling reality: The country is wasting vast amounts of wind and solar power because its coal-dominated grid cannot flexibly integrate them. A neglected study from the Centre for Research on Energy and Clean Air (CREA), summarized by the South China Morning Post and brought to light by analyst Ethan Tan, reveals that China’s renewable capacity is largely a mirage. The installed hardware exists, but the electricity it could produce is squandered due to inflexible grid management, medium-term coal contracts, and transmission bottlenecks. For Western nations racing to adopt wind and solar, China’s failure offers a stark warning: capacity without integration is not just waste, it is a costly deception.

Key points:

• China’s renewable capacity hit 60.4 percent of total installed capacity by March, but actual generation lagged at 37 percent.
• Wind generation showed almost no growth despite a 23 percent rise in capacity, and solar output dropped in efficiency.
• Inflexible coal plant operations, locked into fixed-price contracts, prevented grid operators from scaling back coal to make room for renewables.
• The wasted clean energy potential exceeded France’s total power generation for the same period.
• Nuclear power, which provides steady baseload electricity, is essential for integrating variable wind and solar without relying on coal.

China’s National Energy Administration reported that in the first quarter of this year, electricity consumption rose by 5.2 percent year on year, an increase of about 120 terawatt-hours. The country’s record-breaking expansion of solar and wind capacity should have been able to cover that increase comfortably. According to CREA, that new capacity alone could have generated an extra 160 terawatt-hours compared to the same period last year. If nuclear and hydro-power were included, the potential clean energy supply reached 170 terawatt-hours, exceeding France’s total power generation over the same period. Yet the actual increase in clean power generation was just 60 terawatt-hours.

Wind generation showed almost no growth despite a 23 percent rise in wind capacity and a 33 percent rise in solar capacity compared to the first quarter of 2025. The culprit was a drop in the capacity factor, meaning the electricity output per unit of installed capacity fell sharply. It’s poorly integrated and not dependable in a consistent way. This drop in renewable output forced a growth in fossil fuel-based power generation to fill the gap.

The coal contracts fill the gap left behind by renewables

The key reason for this wasted wind and solar generation was not a lack of grid infrastructure, as some officials have claimed. CREA stated plainly that the problem was the inflexible management of coal power plants and power grids. Coal-fired power generation in China is largely operated via medium- and long-term contracts that require supplying fixed amounts of electricity at fixed prices. This system creates no incentive for coal plant operators to adjust their output downward when solar and wind are abundant. Instead, coal plants keep churning out power, and renewables are curtailed.

This is a structural flaw that Western energy planners must take seriously. Many European countries and U.S. states have set aggressive renewable targets without first reforming how base-load power plants are dispatched. If coal, or even natural gas, is locked into inflexible contracts, adding more solar panels and wind turbines only increases the amount of wasted energy. China now loses money on its wind and solar buildout because transmission capacity to move power from remote desert installations to coastal cities is insufficient. The country has a tiger by the tail: massive installed capacity that cannot deliver.

Why nuclear power is the missing link for renewable integration

China’s experience demonstrates that wind and solar cannot stand alone, especially when coal plants refuse to budge. Nuclear power, by contrast, provides steady, dispatchable baseload electricity that can be ramped up or down to complement variable renewables. Nuclear plants operate continuously, but modern reactor designs allow for load-following, meaning they can adjust output to match grid demand without the rigid contractual constraints of coal. In France, nuclear power already supplies over 70 percent of electricity, and the grid there integrates wind and solar far more effectively because nuclear plants can be coordinated with renewable output.

The lesson for the West is clear. Building vast amounts of wind and solar without simultaneously reforming grid management and deploying nuclear base-load leads to waste, higher costs, and continued reliance on coal or gas. China’s renewable push is more bark than bite, as Tan put it, because the underlying systems are not designed for flexibility. Western countries that follow the same path without nuclear integration will repeat China’s mistake, only with higher electricity prices and lower reliability.
