China’s government has initiated fundamental reforms in renewable energy pricing, transitioning from fixed coal-linked prices to competitive auctions, which may significantly lower renewable energy costs and facilitate coal’s exit from the power sector. Governed by a new mechanism similar to the UK’s Contract for Difference, the system’s effectiveness will depend on practical implementation and policy design, with three potential outcomes for the future of renewables and coal in China.
The recent announcement by China’s central government regarding a significant overhaul of renewable energy pricing aims to shift towards a competitive auction system for wind and solar electricity. Previously, operators were guaranteed fixed prices tied to coal rates, but the new approach eliminates this linkage, potentially leading to a reduction in renewable electricity costs and a greater displacement of coal power. Local governments are mandated to implement this auction-based pricing mechanism by year-end, affecting projects initiated after June, while older projects will continue under the existing fixed-rate model.
This revised pricing structure mirrors the Contract for Difference (CfD) mechanism utilized in the UK, where renewable energy producers compete to offer electricity at a predetermined strike price. If market prices dip below this strike price, the government compensates the difference; conversely, excess earnings must be returned to the government. Although CfDs have successfully provided stability in revenue for renewables in other markets, they can lead to certain risks, such as continued generation during negative price conditions, which occurred in Germany’s wind sector.
China’s power market presents unique challenges distinct from western systems, given the continued dominance of coal, which comprised approximately 60 percent of power generation as of late 2024. The country’s spot electricity market is still developing, and coal pricing remains significantly influenced by coal generation costs. Due to these intertwined factors, the determination of an equitable market reference price for the CfD system raises concerns about whether it will reflect the true generation costs.
Declining costs for wind and solar energy pose another potential hurdle, as upcoming strike prices may be significantly lower than current coal benchmarks. Consequently, companies could push bids lower to secure contracts, resulting in decreased returns on investment. Moreover, strict local government regulations on bidding could undermine the competitive nature of auctions, reverting the pricing system to one dominated by government control.
The pathway to effective implementation of CfDs in China entails navigating the balance between government control and market-driven initiatives. Three distinct scenarios elucidate possible futures: the first involves a rapid coal phase-out as renewables gain priority and operational efficiencies; the second depicts a slower transition where policy facilitates gradual shifts; the third scenario presents a scenario of entrenched coal dominance with minimal impact from renewables.
The potential of China’s CfD system profoundly hinges on strategic policy design and implementation. For CfDs to spur substantial emissions reductions, they must enable a significant transition from coal to renewables rather than simply increasing capacity. A crucial indicator of success will be whether the CfD system remains profitable or continually incurs deficits, reflecting the competitive viability of renewables against coal. Overall, robust policy frameworks and proactive market adjustments are indispensable to facilitate this energy transition in China.
In conclusion, China’s reform of renewable energy pricing through the introduction of competitive auctions marks a critical step towards minimizing reliance on coal. The success of this transition will depend on effective implementation and strategic policy adjustments, ensuring that renewables can not only coexist with but predominantly replace coal power. As the situation evolves, monitoring the profitability of the CfD mechanism will be essential for evaluating progress in decarbonizing China’s energy sector and reducing carbon emissions significantly.
