Influencing factors of Yunnan electricity price

According to the query of power grid and Chinese government network, the influencing factors of Yunnan electricity price mainly include the following aspects:

1. Hydropower resources: Yunnan is a major hydropower province in China, with hydropower accounting for 73% and more than 80% of the total installed power generation in the province. The abundance and decline of hydropower resources are affected by climate change. Drought and insufficient rainfall will reduce hydropower production, thus affecting the formation of electricity prices.

2. Thermal power cost: Yunnan thermal power accounts for 14% of the province's installed power generation, and thermal power generation only accounts for 9%. The cost of thermal power is affected by coal price, transportation cost, environmental tax and other factors, and thermal power enterprises often face the risk of loss and bankruptcy. In order to ensure the survival of thermal power enterprises and the regulation ability of the system, Yunnan has implemented the market-oriented reform of coal-fired power and regulated the capacity market, allowing the price of coal-fired power to fluctuate by 20% around the benchmark price, and allocating the regulation capacity cost according to the different needs of various power sources and users.

3. New energy consumption: Yunnan's new energy accounts for 13% of the province's installed power generation capacity, mainly including wind energy, solar energy and biomass energy. New energy has the characteristics of intermittence, uncertainty and fluctuation, so it needs to be equipped with energy storage facilities or other flexible regulating power sources to ensure the stable operation of the system. Through the implementation of the time-of-use electricity price mechanism, Yunnan determines the period when the supply and demand of the system are tight and the marginal power supply cost is high as the peak period, and determines the period when the supply and demand of the system are loose and the marginal power supply cost is low as the trough period, so as to guide users to save electricity, avoid peaks by shifting peaks and promote the consumption of new energy.
