China accelerates market integration of wind and solar generation

On 27 January 2025, China’s National Development and Reform Commission (NDRC) and the National Energy Administration (NEA) jointly issued a policy titled “Notice on Deepening the Marketisation Reform of Feed-in Tariffs for New Energy to Promote High-Quality Development of New Energy”. This policy marks a shift in China’s approach to pricing wind and solar power, transitioning from fixed tariffs to a market-based system. 

The policy allows market mechanisms to determine the feed-in tariffs for wind and solar power in China. It seeks to make resource allocation more efficient, promote a fair competition, and contribute to the sustainable development of the renewable energy industry. This shift aligns with China’s broader strategy to build a modernised power system and achieve its carbon neutrality targets. 

The policy delineates distinct rules for projects based on their commissioning dates. For wind and solar projects commissioned before 1 June 2025, the current pricing mechanism is applicable, ensuring price stability. The feed-in tariffs for these projects will not exceed the local benchmark prices for coal-fired generation. Projects commissioned after 1 June 2025 will follow the market-based pricing. The electricity price will be entirely determined by competitive bidding, with an upper price limit set by local authorities. Projects with electricity prices set in that way will participate in a price difference settlement mechanism, which will be established outside the market. The settlement mechanism is similar to a contract for differences and will compensate projects for the difference when the market price is below the mechanism price, while it deducts the excess when the market price is higher. Grid companies will be responsible for carrying out price difference settlements, with the settlement costs included in local system operating costs. 

It also calls for enhancing market trading rules by improving the spot and long-term power market mechanisms. It emphasises the need to refine both spot market transactions and long-term power trading mechanisms. This includes adjusting trading cycles, increasing transaction frequencies, and allowing flexibility in contract terms to better accommodate the characteristics of renewable generation.  

The policy promotes green electricity trading by encouraging the development of green electricity trading markets, where renewable energy certificates (green certificates) can be traded. This initiative aims to standardise trading practices across regions and reduce reliance on subsidies.  

It underscores the importance of policy coordination recognising the complexity of this transition. Provinces are mandated to finalise and implement their specific plans by the end of 2025. These plans should align with national renewable energy development goals and ensure a smooth transition to the new pricing mechanism. The policy calls for active engagement with stakeholders, including energy producers, grid operators, and consumers, to address concerns and ensure that the reform’s objectives are met without causing undue disruptions.

China establishes assessment system for carbon peaking and carbon neutrality targets

Jointly issued by the General Office of the Communist Party of China (CPC) and Central Committee and the General Office of the State Council, this policy “Measures on Comprehensive Evaluation and Assessment for Carbon Peaking and Carbon Neutrality”, establishes a formal assessment system for evaluating how provincial-level Party committees and governments implement China’s carbon peaking and carbon neutrality objectives.
The assessment work is coordinated centrally and implemented by the National Development and Reform Commission together with relevant departments. It applies to provincial-level Party committees and governments, including provinces, autonomous regions, and municipalities.

China sets new framework for energy conservation and carbon reduction

The General Office of the Communist Party of China (CPC) Central Committee and the General Office of the State Council jointly issued two policies to strengthen energy conservation, carbon reduction, and the assessment of climate-related targets.
This article looks at the first policy, “Opinions on Advancing Energy Conservation and Carbon Reduction at a Higher Level and with Higher Quality”, which sets out a broad policy framework for improving energy efficiency, reducing carbon emissions, controlling fossil fuel consumption, and accelerating green industrial transformation.
