Multiple regions in China, including Guizhou, Hubei, and Shaanxi, are discontinuing the fixed time-of-use (TOU) electricity pricing system, which has been in effect for over four decades. This change transfers the authority for setting peak and off-peak electricity rates from government bodies to market mechanisms.
The rationale behind this reform stems from changes in the electricity supply structure. The increasing integration of renewable energy sources, such as solar and wind power, has led to more variable supply patterns. The traditional fixed TOU system, with its predetermined price periods, is seen as increasingly inadequate in reflecting these real-time market conditions and the actual cost of electricity generation.
This shift is supported by the expansion of provincial electricity spot markets across China, which provide a platform for real-time price discovery. The move away from fixed TOU pricing is also aligned with national policies that encourage market-based formation of electricity prices. Provinces are implementing this change through different approaches, including full market integration for all users and phased rollouts with transitional measures.
For consumers, the immediate impact on residential electricity prices is expected to be minimal in the short term. However, the long-term objective is to use these market-driven price signals to guide users towards more rational electricity consumption planning. The reform also necessitates adjustments in business models for entities like energy storage providers, who previously relied on fixed price differentials.
