01 Guangdong Provincial Power Trading Center issued the "Bidding Rules for the Sustainable Development Price Settlement Mechanism for Incremental New Energy Projects in Guangdong Province (Draft for Comments)" and the "Differential Settlement Rules for the Sustainable Development Price Settlement Mechanism for New Energy Power Generation Projects in Guangdong Province (Draft for Comments)" (May 12)

On May 12, the Guangdong Provincial Power Trading Center issued the "Bidding Rules for the Sustainable Development Price Settlement Mechanism for Incremental New Energy Projects in Guangdong Province (Draft for Comments)" and the "Differential Settlement Rules for the Sustainable Development Price Settlement Mechanism for New Energy Power Generation Projects in Guangdong Province (Draft for Comments)", giving relevant requirements on the detailed rules for new energy bidding in Guangdong Province.

Bidding Organization Time

Bidding transactions are organized at the end of each year for new energy projects that have been put into operation and will be put into operation in the following year. The first bidding transaction will be organized in mid-2025.

Bidding Power Scale

The annual scale of newly included power under the mechanism is determined by the Guangdong Provincial Development and Reform Commission and the Guangdong Provincial Energy Bureau and will be announced before the bidding.

The upper limit of the mechanism power declaration ratio is no more than 90%.

The upper limit of the mechanism power ratio declaration is linked to the mechanism power ratio of existing projects and is no more than 90%. For medium- and long-term transaction power and green power that have been traded within the bidding cycle, the upper limit of the bidding declaration ratio will be reduced accordingly.

Bidding Mechanism

A centralized bidding method is used for bidding transactions. According to the declared power ratio of new energy projects, the absolute value of power corresponding to the declared ratio of new energy projects is calculated based on the historical hourly data and project capacity of the same type in the past three years. The absolute value of power is sorted according to the bids of new energy projects from low to high. If the prices are the same, the order is determined according to the priority of the declaration time until the total bidding scale is met, and all new energy projects within the total bidding scale are traded. The declared ratio of the last project traded is fully traded. The mechanism price of all selected projects in this bidding transaction is determined according to the highest bid of the selected projects, and the mechanism power ratio is the declared mechanism power ratio. Unsuccessful new energy projects can continue to participate in subsequent bidding transactions.

Mechanism Price Implementation Period

The implementation period of the mechanism price for incremental projects is 14 years for offshore wind power projects and 12 years for other new energy projects. The mechanism price will no longer be implemented after the expiration date. After the incremental project successfully participates in the bidding, the start time of the implementation for projects that have not been put into operation is determined according to the commissioning time declared at the time of bidding; for projects that have been put into operation, it is determined according to the selection time.

Commissioning Time Determination

New energy projects of 10 kV and above: The final date of the two is confirmed according to the grid connection date specified in the power business license and the time when the project quality supervision grid connection opinion is issued;

For projects below 6 MW that are exempted from power business license processing and quality supervision: The official commissioning time document issued by the project owner is used for determination, and the power dispatching institution is responsible for providing it.

For new energy projects below 10 kV, the local grid enterprise provides the grid connection acceptance time of the last batch of projects that meet the capacity of the filing certificate as the commissioning time.

Penalty for Failure to Meet Grid Connection Deadline

Photovoltaic and wind power projects that do not meet the requirements of "four availabilities" (observable, measurable, adjustable, and controllable) at the time of commissioning will automatically invalidate the mechanism power and will not be settled before meeting the requirements of "four availabilities", and the start date of the mechanism price implementation will remain unchanged. If a new energy project that has already implemented the mechanism price registers to participate in the bidding transaction, the selection result of that project in that bidding will be invalidated.

After an incremental project successfully participates in the bidding, if the actual commissioning time of the project that has not been put into operation is delayed by less than 6 months compared to the commissioning time declared at the time of bidding, the bidding result can be retained, and the contract-covered power before the actual commissioning date will automatically become invalid and will not be settled. If the delay is 6 months or more, the selection result of that bidding will be invalidated, and the bidding qualification of that project will be cancelled for three years.

Projects Eligible for Bidding

The first bidding transaction will be organized in mid-2025, covering new energy projects put into operation, approved, and filed after June 1, 2025. Projects participating in the first bidding must be put into operation before December 31, 2025.

Settlement Price

New energy projects implementing the differential settlement mechanism for mechanism power must clearly state the mechanism power ratio and the source of the mechanism price level in the contract. Among them, the mechanism price and mechanism power ratio of existing projects are implemented according to the "Implementation Plan for Deepening the Market-Oriented Reform of New Energy On-Grid Prices and Promoting the High-Quality Development of New Energy" (hereinafter referred to as the "Plan") issued by the Guangdong Provincial Energy Bureau. The mechanism price of incremental projects is implemented according to the bidding results provided by the power trading institution and combined with the implementation period. The mechanism power ratio is implemented by taking the smaller value of the plan or the bidding results provided by the power trading institution, and the results of the new energy project application adjustment.

02 Hebei Provincial Development and Reform Commission issued the "Hebei Province 2025 Power Load Management Work Plan" (May 9)

On May 9, the Hebei Provincial Development and Reform Commission issued a notice on the issuance of the "Hebei Province 2025 Power Load Management Work Plan."

The document is formulated in combination with the electricity consumption characteristics of summer and winter in 2025.

Hebei Province's supply and demand situation:

In summer, the estimated peak and off-peak maximum loads of the Hebei Southern Grid are 55 million kW and 51.5 million kW respectively, with a power supply gap of approximately 3 million kW during the off-peak hours; the peak and off-peak maximum loads of the Hebei Northern Grid are 32 million kW and 31 million kW respectively, with a stable power supply and demand balance.

In case of extreme situations, the power supply gap may further increase, with 5 million kW for the Southern Grid, and 4.73 million kW for the Northern Grid, which will be shared with Tianjin at a ratio of 2:1 according to the unified balancing principle of Beijing, Tianjin, and Hebei.

In winter, the estimated peak and off-peak maximum loads of the Hebei Southern Grid are 51.5 million kW and 49 million kW respectively, with a power supply gap of approximately 1.5 million kW; the peak and off-peak maximum loads of the Hebei Northern Grid are 33 million kW and 34 million kW respectively, with a stable power supply and demand balance.

In case of extreme situations, the power supply gap may further increase, with 3.5 million kW for the Southern Grid, and 7.07 million kW for the Northern Grid, which will be shared with Tianjin at a ratio of 2:1 according to the unified balancing principle of Beijing, Tianjin, and Hebei.

Energy storage related content:

During periods of tight power supply, users with energy storage equipment should optimize their charging and discharging strategies, enhance peak discharge capacity, and reduce grid load during peak hours. Users with self-owned generators, such as steel mills and large data centers, are encouraged to increase production and generation or switch to off-grid self-supply without compromising safety, participating in demand response to obtain subsidies. Langfang and Zhangjiakou cities should organize large data center users to carefully verify the off-grid self-supply capacity of diesel generators, establish an off-grid operation plan for each user in case of tight power supply and demand, and sign demand response agreements.

Continuously expand the demand response resource pool. The power operation management departments and grid companies of various cities should widely carry out publicity on demand response policies, and guide user-side energy storage, cold chain logistics, air conditioning, industrial flexible maintenance, and self-owned power plants and other flexible load resources into the demand response resource pool.

03 The Shandong Provincial Development and Reform Commission recently issued the "Shandong Province New Energy On-grid Electricity Price Market-oriented Reform Implementation Plan (Draft for Comments)" and the "Shandong Province New Energy Mechanism Electricity Price Bidding Implementation Rules (Draft for Comments)" (May 7).

On May 7, the Shandong Provincial Development and Reform Commission recently issued the "Shandong Province New Energy On-grid Electricity Price Market-oriented Reform Implementation Plan (Draft for Comments)" and the "Shandong Province New Energy Mechanism Electricity Price Bidding Implementation Rules (Draft for Comments).

Shandong has become the first province in China to publicly release the implementation rules of Document No. 136.

The "Implementation Plan" points out that after the full amount of electricity from existing new energy projects put into operation before May 31, 2025 participates in market transactions, the mechanism electricity price level will be implemented according to the national policy upper limit, which is uniformly defined as 0.3949 yuan/kWh (including tax); the upper limit of the mechanism electricity for a single project will refer to the non-marketization rate of new energy in other provinces, and will be moderately optimized; the implementation period will be implemented according to the remaining hours of the reasonable utilization hours of the full life cycle.

For incremental new energy projects put into operation from June 1, 2025, the provincial development and reform commission, together with relevant units, will clarify the scale and implementation period of mechanism electricity, and determine the mechanism electricity price level through price competition. A lower limit for the application sufficiency rate will be set to guide sufficient competition among new energy sources, reduce the cost of energy use for the whole society, and the bidding application sufficiency rate in 2025 will be no less than 125%. During the bidding, the selected projects will be determined in ascending order of the reported price, and the mechanism electricity price will be determined in principle according to the highest bid of the selected projects (not exceeding the bidding upper limit).

The electricity included in the mechanism is protected by the mechanism electricity price, and the corresponding electricity will no longer participate in green electricity trading and will not receive green certificate income repeatedly.
