01 National Development and Reform Commission Issues "Management Measures for Cross-Provincial and Cross-Regional Power Emergency Dispatch (Draft for Comments)"

On June 13, the National Development and Reform Commission issued the "Management Measures for Cross-Provincial and Cross-Regional Power Emergency Dispatch (Draft for Comments)". It proposes that the landing-side electricity price in the receiving province during emergency dispatch should be determined by the highest value of the upper limit of the inter-provincial spot market settlement price or the upper limit of the clearing price of the Southern Regional spot market.

If the receiving province's landing electricity price minus the sending province's on-grid electricity price, transmission prices at various stages, and line loss discount is positive, the relevant costs will be included in the sending province's system operating costs, shared by the sending province's users and power generation enterprises at a ratio of 80% and 20%, respectively; if it is negative, the relevant costs will be included in the receiving province's system operating costs, shared by the receiving province's users. Power generation enterprises will be settled according to the sending province's market transaction price plus the shared portion. The transmission price and line loss discount for emergency dispatch shall be implemented according to the standards determined by the national price-regulating authorities.

Following the principle of "whoever supports, whoever benefits, whoever benefits, whoever bears the responsibility", the allocation and sharing methods of emergency dispatch electricity and electricity charges in the sending province's power generation and user sides and the receiving province's user side are clarified. Grid enterprises and power trading institutions shall separately collect the relevant electricity and electricity charges for emergency dispatch in accordance with regulations. Emergency dispatch electricity shall not be included in the allocation of auxiliary service fees and deviation electricity assessment.

01 Hunan Regulatory Office of the National Energy Administration Publicly Solicits Opinions on Hunan Power Market Series Rules

On June 17, the Hunan Regulatory Office of the National Energy Administration publicly solicited opinions on the Hunan power market series rules. It mentioned that operating entities refer to entities that meet the requirements of the power market and have observable, measurable, adjustable, and controllable capabilities, mainly including thermal power (including coal-fired, gas-fired, and thermal storage), hydropower (including pumped storage), energy storage, and virtual power plants.

Among them, the detailed rules for the implementation of the Hunan Provincial Power Frequency Regulation Auxiliary Service Market Transaction mentioned that grid-side independent energy storage with a voltage level of 110 kV and above shall have a frequency regulation capacity of no less than 15 MW and a duration of no less than 1 hour.

Independent new energy storage, pumped storage, and virtual power plants will not participate in the sharing of frequency regulation market service fees for the time being.

In addition, the frequency regulation market parameter table mentions that the comprehensive frequency regulation performance index entry threshold is 0.3, the frequency regulation mileage price bidding range is 3 yuan/MW-15 yuan/MW, the independent energy storage clearing capacity upper limit is the rated capacity, and the upper limit of the total winning capacity of energy storage accounts for 30% of the total demand.

02 Wenzhou Development and Reform Commission Announces the "Implementation Plan for Peak-Shaving and Summer (Winter) Power Supply Subsidies at the Wenzhou Municipal Level (Draft for Comments)"

On June 17, the Wenzhou Development and Reform Commission announced the "Implementation Plan for Peak-Shaving and Summer (Winter) Power Supply Subsidies at the Wenzhou Municipal Level (Draft for Comments)", mentioning that industrial users who use electrochemical energy storage peak discharge during the specified period according to municipal instructions will receive a subsidy of 1 yuan/kWh.

It is worth noting that this policy adds an air conditioning management subsidy, providing a subsidy of 0.2 yuan/kWh to commercial users such as office buildings, hotels, and large supermarkets that effectively reduce their power consumption during periods of power tension.

Demand response subsidies: For industrial and commercial users who effectively respond during periods of power tension, the subsidy will be supplemented to 4 yuan/kWh based on the provincial demand response subsidy.

This policy will be implemented from June 15, 2025, and will be valid until January 31, 2026.

03 Hainan Provincial Development and Reform Commission Solicits Opinions on the "Implementation Rules for Hainan Provincial Power Demand Response (Draft for Comments)"

On June 16, the Hainan Provincial Development and Reform Commission solicited opinions on the "Implementation Rules for Hainan Provincial Power Demand Response (Draft for Comments)". It mentioned that scheduled peak-shaving response will follow the principle of "one-time application, cycle rolling, and day-ahead dispatch", with a fixed compensation price of 1.0 yuan/kWh, compensated according to the dispatched electricity. In the month of demand response implementation, the un-dispatched portion will enjoy standby capacity compensation, with a compensation standard of 0.3 yuan/kW month.

Day-ahead invited peak-shaving response will be compensated according to the clearing price and response electricity of a single response, with an upper limit of 1.5 yuan/kWh for the compensation unit price.

Intraday emergency (interruptible load) peak-shaving response will be compensated according to the clearing price and response electricity of a single response, with an upper limit of 2 yuan/kWh for the compensation unit price.

Day-ahead invited valley-filling response will be compensated according to the clearing price and response electricity of a single response, with an upper limit of 0.3 yuan/kWh for the compensation unit price.

Intraday emergency valley-filling response will be compensated according to the clearing price and response electricity of a single response, with an upper limit of 0.4 yuan/kWh for the compensation unit price.

Demand response resources include electricity loads for production, auxiliary, and office life in industrial production, cooling electricity loads such as centralized air conditioning and decentralized air conditioning in buildings, ice storage cooling, energy storage facilities, electric vehicle charging piles, V2G electric vehicles, and other smart electricity facilities. "Two High" project resources are encouraged to register and participate in demand response preferentially.

Virtual Power Plants. Entities with legal person qualifications, independent financial accounting, good credit, and the ability to independently bear civil liability, such as load aggregators, power sales companies, or power users, can register as virtual power plants, achieving the aggregation and coordination of adjustable loads, new energy storage, distributed power generation, electric vehicles, and other demand-side resources. Aggregable resources need to be identified by the provincial power load management center, and the total regulation capacity should generally be no less than 1000 kW.

At present, the valley-filling demand response does not assess the implementation effect. During the peak-shaving demand response, if the actual response capacity of the operating entity does not reach 50% of the winning response capacity, the invalid response capacity of the winning operating entity will be assessed. The assessment fee will be calculated hourly, and the specific calculation formula is as follows: Hourly assessment fee = (Winning response capacity × 50% - Actual response capacity) × Clearing price × M (0.5), where M is the penalty factor, adjusted according to the market operation situation.

Shaanxi Provincial Development and Reform Commission and Northwest Regulatory Bureau of the National Energy Administration Issue the "Implementation Plan for Serving the Construction and Operation of Virtual Power Plants in Shaanxi Province"

On June 16, the Shaanxi Provincial Development and Reform Commission and the Northwest Regulatory Bureau of the National Energy Administration jointly issued the "Implementation Plan for Serving the Construction and Operation of Virtual Power Plants in Shaanxi Province." The plan mentions that distributed photovoltaic, energy storage, and other types of regulating resources aggregated by virtual power plants should meet the technical performance standards and grid management requirements for the corresponding resource types. When the power grid experiences emergency supply-demand imbalances or operational safety issues such as equipment overload, the aggregated resources of the virtual power plant should, in accordance with dispatch management regulations, unplanned power curtailment and accident power curtailment plans, orderly power use plans, and emergency plans, undertake the obligations of grid balancing and safety, strictly execute dispatch instructions, and virtual power plant operators must not interfere with the transmission and execution of dispatch instructions.

In addition, aggregated resources should be operating entities with independent marketing account numbers from power grid enterprises and registered on the power trading platform, promoting the gradual entry of existing virtual power plant grid-agent electricity purchasing users into the market. Generation and energy storage resources directly managed and dispatched by power dispatching institutions are not included in the aggregation scope.

In terms of settlement, for virtual power plant operators participating in demand response services, the load management center will calculate subsidy fees for operators and aggregated power users according to the agreed terms, and transmit the settlement results and basis to the electricity fee settlement management department.

For virtual power plant operators participating in the medium- and long-term electricity energy market, the spot electricity energy market, and the ancillary service market, the power trading institution will conduct settlement in accordance with the "Implementation Plan for Innovative Support of Virtual Power Plants Participating in High-Quality Development of the Power Market in Shaanxi Province," relevant rules, and regulations of the Shaanxi power market, and push the settlement basis to the power grid enterprise. Based on the settlement basis provided by the power trading institution, the power grid enterprise will issue monthly settlement bills to the virtual power plant operators and aggregated power users and make payments to and collect payments from the virtual power plant operators and aggregated power users according to regulations.

Virtual power plant operators should abide by the relevant assessment rules for power demand response, electricity energy market, and power ancillary service market and bear the corresponding assessment fees. For deviations caused by policy changes or force majeure in market transaction settlement rules and transaction prices that require adjustments to settlement fees, the Shaanxi Provincial Power Company will provide refunds or supplements according to the corresponding power market transaction rules.

The Henan Provincial Development and Reform Commission issued the "Work Plan for the First Settlement Trial Run of the Henan Power Spot Market in 2025"

On June 13, the Henan Provincial Development and Reform Commission replied, agreeing to conduct the first settlement trial run of the Henan Power Spot Market in 2025, and simultaneously issued the "Work Plan for the First Settlement Trial Run of the Henan Power Spot Market in 2025."

Trial Run Time: The first settlement trial run of the Henan Power Spot Market in 2025 will be conducted from June 19 to 27. Day-ahead market reporting will begin on June 18, and June 19 and 20 will be for power adjustment trial runs. During the power adjustment trial run, unit combinations will be executed according to market clearing results. Settlement will be implemented from June 21 to 27.

It is worth noting that during the power adjustment trial run, the peak regulation ancillary service market will operate normally. On June 18 and 19, operating entities should normally report to the peak regulation market for use in peak regulation ancillary service market dispatch and settlement.

Scope of Operating Entities: Generation side—all grid-connected coal-fired power generation enterprises and centralized renewable energy power stations participating in the current medium- and long-term transactions; user side—ordinary market-oriented electricity users; independent energy storage, virtual power plants.

Day-ahead Reporting:

Independent Energy Storage: Participate in the spot market with "reporting quantity without reporting price." Report the day-ahead operation curve in day-ahead reporting. The on-grid electricity volume will accept the day-ahead spot price of the generation side in the sub-area where the energy storage power station is located, and the off-grid electricity volume will accept the day-ahead spot weighted average price of the generation side across the entire grid. The real-time market will be dispatched according to the day-ahead operation curve. The deviation of the on-grid electricity volume will be settled according to the real-time price of the generation side in the sub-area where the energy storage power station is located, and the deviation of the off-grid electricity volume will be settled according to the real-time spot weighted average price of the generation side across the entire grid. If the inconsistency between the real-time operation curve and the day-ahead operation curve is caused by the energy storage power station itself, the deviation gains and losses will be borne by the energy storage power station itself; if the inconsistency is caused by the power grid, the deviation profit will be retained, and the loss will be compensated according to the day-ahead deserved income.

Reporting Parameters: For this trial run, the minimum limit price for the spot electricity energy market is 50 yuan/MWh, and the maximum limit price is 1200 yuan/MWh. The limit price range will be gradually adjusted according to national requirements.

According to the list of participants in the power spot market trial run, a total of 12 independent energy storage power stations participated this time.

Settlement Plan:

During the settlement trial run, when the charging and discharging curve of independent energy storage is inconsistent with the day-ahead reported curve due to grid dispatch, when the deviation is settled between the day-ahead curve and the real-time curve, if the total cost is lower than the day-ahead income, compensation will be made for the reduced cost. This is counted as compensation for independent energy storage due to grid adjustments.

Profit and Loss Risk Control:

Independent energy storage will be compensated if the daily average electricity energy income per 10,000 kW capacity is less than 7,650 yuan due to a small spot price difference.

During the settlement trial run, when the total settlement cost of independent energy storage (per 10,000 kW) in the spot market is less than the product of the number of settlement days and 7,650 yuan, compensation will be made for the insufficient part.

06 Qinghai Power Market Management Committee issued the "Notice on Voting on Matters Related to the Price Mechanism of the Power Ancillary Service Market"

On June 11, the Qinghai Power Market Management Committee issued the "Notice on Voting on Matters Related to the Price Mechanism of the Power Ancillary Service Market."

The notice points out that the Northwest Regulatory Bureau of the National Energy Administration has clarified (draft for deliberation) matters related to the price mechanism of the power ancillary service market: the upper limit of the peak regulation ancillary service market price has been adjusted, and it is proposed to strengthen the connection between the ancillary service market and the spot market.

I. Adjustment of the Upper Limit of the Peak Regulation Ancillary Service Market Price

Adjust the upper limit of the peak regulation ancillary service market price according to the principle of not exceeding the on-grid price of local parity renewable energy projects. Peak regulation transactions in the ancillary service markets of Shaanxi, Ningxia, and Qinghai will no longer be divided into grades:

The upper limit of peak regulation transactions for virtual power plants in Ningxia will remain at 0.19 yuan/kWh, and the upper limit of the reported price for other types of peak regulation transactions will refer to the execution of deep peak regulation transactions for thermal power plants.

The peak regulation price for grid-dispatched energy storage in peak regulation transactions in Qinghai is tentatively set at 0.3247 yuan/kWh.

II. Strengthening the Connection between the Ancillary Service Market and the Spot Market

When the power spot market is not operating, the power peak regulation ancillary service market will operate according to market rules; during the settlement trial run, peak regulation ancillary services will not be compensated. After the continuous operation of the spot market, the peak regulation ancillary service market will generally no longer operate, promoting operating entities to respond to spot market price signals to participate in peak shaving and valley filling, and the corresponding functions of the peak regulation market will be integrated into the spot market.
