Recently, Shandong State Grid Shandong Electric Power Company "Announcement on the release of 2025 time-of-use electricity price implementation period". Since January 1, 2025, Shandong energy storage has ushered in the era of two charges and two discharge.

Changing aspect

(1). The biggest change in January, February and December is the increase of 2 hours in the peak period and 4 hours in the trough period.
(2). In June, 0-6pm changed from the original trough to a flat segment; From 7 to 12 o 'clock from the original flat to the trough, the peak hour increased by 1 hour.
(3).From July to August, the off-peak electricity in the early morning hours is delayed by 1 hour, and the peak hours are increased by 1 hour.
Overall, the further improvement of the TOU tariff mechanism has maintained the basic stability of the average price of industrial and commercial users, which is conducive to better guide users to cut peaks and fill canyons, improve power supply and demand, and promote the consumption of new energy, which is of positive significance to both short-term protection of power security and stable economic operation, and the realization of carbon peaking and carbon neutrality in the medium and long term.

1.Scope of implementation of TOU tariff

Industrial and commercial user capacity compensation price, online link line loss cost, system operation cost, and power grid enterprise agent purchasing power users (excluding the state has special provisions for electrified railway traction electricity) agent purchasing power price to implement the TOU price policy, various kinds of sharing profit and loss and other electricity price parts do not implement the TOU price policy.

Note: The metering device for customers with less than 1 kV agent power purchase has been dynamically adjusted, and the same time-sharing period has been implemented with high-voltage industrial and commercial users since January 1, 2025.

2.Time-of-use tariff floating ratio

70% float up during peak hours, 70% float down during trough hours, 100% float up during peak hours, and 90% float down during deep valleys.

3.Industrial and commercial energy storage challenges

Security challenges. The safety of industrial and commercial energy storage systems is a primary concern. Faults such as short circuit and overheating may cause fire and explosion, especially in large business districts and factory parks with dense personnel, and the potential risks are huge.

The economic return challenge. Economy is another major pain point restricting the development of industrial and commercial energy storage. The initial investment of energy storage equipment is large, and affected by factors such as electricity price policy and market demand, the return cycle of the project is long, which increases the investment risk of enterprises.

Technical challenges. There are technical problems in capacity calculation, performance optimization and operation and maintenance management of industrial and commercial energy storage systems. At present, the technical level of energy storage systems on the market is uneven, and some systems have problems such as inaccurate capacity calculation and unstable performance, which affect the application effect of energy storage systems.

Market competition challenge. Market problems are mainly manifested as insufficient market demand, fierce competition and so on. At present, the industrial and commercial energy storage market is still in the early stage of development, the market demand has not yet been fully released, and the competition in the industry is increasingly fierce, and enterprises are facing greater market pressure.

The policy challenge. Policy problems mainly include policy uncertainty and insufficient policy implementation. The uncertainty of the policy increases the investment risk of the enterprise, and the lack of policy implementation may lead to the smooth implementation of the project.
