China’s Green Power Trading Surges, Signaling Maturity of Market Mechanisms and Energy Reform

China’s green power market is accelerating into a new phase, with trading volumes surging nearly 50% year-on-year in the first five months of 2025—surpassing 220 billion kilowatt-hours, according to data from the China Electricity Council (CEC). The sharp rise underscores the country’s ongoing pivot from centrally planned electricity dispatch toward a market-driven system that more effectively integrates renewable sources into the national grid.

Experts say this momentum reflects a maturing power market and robust demand for clean electricity. Lin Boqiang, director of the China Institute for Studies in Energy Policy at Xiamen University, emphasized that green electricity’s growing market share is not only a testament to successful policy reforms but also a key step toward decarbonization. “Participation of renewables in market mechanisms is now essential for ensuring grid stability, optimal dispatch, and the economic viability of new energy,” he said.

The numbers tell a story of structural change. Since 2016, China’s market-based power trading volume has climbed from 1.1 trillion kWh to 6.2 trillion kWh in 2024—now accounting for 63% of total national electricity consumption, up from just 17%. Within that, over 1 trillion kWh of power generated from new energy sources—mainly solar and wind—was traded via market mechanisms last year, representing 55% of all renewable generation.

The rapid adoption is also being fueled by growing demand for corporate sustainability. Yang Kun, executive vice-chairman of the CEC, highlighted that green power is now viewed not just as an environmental good but as a driver of enterprise competitiveness in the low-carbon economy. “The environmental value of green electricity is enhancing corporate branding, while pushing the green and low-carbon transformation of the energy sector,” Yang said.

Behind this growth lies improved infrastructure. China’s interprovincial transmission capacity has exceeded 300 million kilowatts, enabling more frequent cross-provincial and cross-regional trades. The construction of a unified national electricity market, now encompassing long-term contracts, spot markets, ancillary services, and green electricity certificates, has laid the foundation for an efficient and flexible energy system capable of supporting a high share of renewables.

China’s energy reforms have also catalyzed massive participation. Market entities registered for electricity trading have ballooned nearly 20-fold in less than a decade, from 42,000 in 2016 to over 816,000 today. With more than half of new energy generation already being sold through market channels, 2024 marked a watershed moment for electricity reform in the country.

The rise of green power trading positions China as a global leader in the integration of renewables through market mechanisms. As it continues building a smarter, greener grid, industry watchers say the country’s approach may offer a blueprint for other emerging economies seeking to transition from fossil-fuel dependency to clean energy leadership.
