Promote energy storage cost recovery to establish capacity compensation! The Southern (starting with Guangdong) Electricity Spot Market Construction Implementation Programme (Trial) was issued!

October 27, Guangdong Province Development and Reform Commission, the National Energy Board Southern Supervisory Bureau issued the "South (to start in Guangdong) power spot market construction implementation programme (pilot)". The document proposes: in order to promote the effective recovery of fixed costs such as energy storage power stations, study the establishment of capacity compensation mechanism. The capacity compensation cost standard is measured according to the investment and construction cost of the unit (power station) and the market operation. Subsequent studies will be conducted to establish a capacity market mechanism.

Compensation for variable costs on the power generation side. In order to solve the problem of large differences in fuel costs among different types of units, the power generation side variable cost compensation mechanism is applied to compensate power generation enterprises for the actual amount of power on the grid, so as to realise competition among different types of units on the same platform. The cost of variable cost compensation is borne by all industrial and commercial users.

Peak-valley balancing mechanism. In order to strengthen the connection with the time-sharing tariff policy and guide users to cut peaks and fill valleys, a temporary user-side peak and valley balancing mechanism is established, and the profit and loss funds generated by the application of the peak and valley balancing mechanism are proportionately shared by the market users who purchase electricity.

The construction objective is that the spot market refers to the day-ahead and real-time electricity energy trading market, adopting the mode of all-electricity bidding, and starting in accordance with the mode of "power generation-side quoted quantity, user-side quoted quantity not quoted quantity", and gradually transitioning to the mode of bilateral quoted quantity for power generation and use.
