Local Policies and News

01 Anhui Provincial Energy Bureau issued the "Notice on the Implementation of the (Management Measures for the Development and Construction of Distributed Photovoltaic Power Generation)" (Draft for Comments) (May 20).

On May 20, the Anhui Provincial Energy Bureau issued a letter soliciting opinions on the "Notice on the Implementation of the (Management Measures for the Development and Construction of Distributed Photovoltaic Power Generation)" (Draft for Comments).

It points out: Effectively manage distributed photovoltaic power generation projects for natural persons, non-natural persons, general industrial and commercial enterprises, and large industrial and commercial enterprises, and actively promote the on-site development and utilization of distributed photovoltaic power generation. The "Notice of the Anhui Provincial Energy Bureau on Doing a Good Job in the Construction Scale Management of Ground Photovoltaic Power Stations Below 6 MW in 2024" (Anhui Energy New Energy Letter [2024] No. 94) clearly states that ground photovoltaic power stations below 6 MW included in construction scale management are managed as centralized photovoltaic projects.

Given the significant differences in the load characteristics of various industrial and commercial enterprises, our province does not currently require a proportion of annual self-generation and self-use electricity for industrial and commercial distributed photovoltaics, and encourages the improvement of the self-generation and self-use ratio through methods such as energy storage synergy and flexible load scheduling. Large-scale industrial and commercial distributed photovoltaics should, in principle, adopt the all-self-generation and self-use mode, but can also adopt the self-generation and self-use surplus power grid-connected mode to participate in the province's electricity spot market. When the user load changes significantly, an application can be submitted to the Provincial Energy Bureau to adjust to a centralized power station.

Regarding the "four available" function transformation, new projects should pass the relevant function tests before grid connection acceptance, and existing projects should be upgraded by grid companies and project units based on the investment and construction efforts at the point of ownership division. In principle, the transformation should be completed before December 31, 2025.

Regarding filing, the Municipal Development and Reform Commissions should strengthen guidance on local filing work, and shall not suspend or delay project filing on the grounds of coordinated development, market rectification, or capacity restrictions. If the construction of distributed photovoltaic projects is temporarily inappropriate due to reasons such as demolition and relocation planning and rural landscape protection, it should be publicly announced to the public in accordance with the law, and the filing entity and grid company should be informed when handling the filing. After the project starts, the filing entity should promptly report the project's commencement, construction progress, completion time, and operation and maintenance entity through the Anhui Provincial Investment Project Online Approval and Supervision Platform. Before the project is put into production, it shall not be transferred to other investors without authorization. The filing work should be completed within one month after the project is completed and connected to the grid.

Regarding the load, it encourages distributed photovoltaic power generation projects to improve on-site consumption capacity through integrated photovoltaics, energy storage, and charging, and synergistic interaction between source, network, load, and energy storage. Projects with all self-generation and self-use distributed photovoltaic power generation based on new loads are not subject to the limit of the accessible capacity.

02 Wenling Municipal People's Government of Zhejiang Province issued the "Notice on Strengthening the Management of New Energy Storage Power Stations in Wenling City" (May 20).

On May 20, the Wenling Municipal People's Government of Zhejiang Province issued the "Notice on Strengthening the Management of New Energy Storage Power Stations in Wenling City." The document stipulates that the construction unit of new energy storage projects should apply for fire protection acceptance or备案抽查 to the Municipal Housing and Urban-Rural Construction Bureau after the completion acceptance is qualified.

For special projects, after receiving the application for fire protection acceptance, the local construction department will organize or entrust a third-party technical institution to conduct on-site evaluation of the construction project and issue a "Construction Project Fire Protection Acceptance Opinion" in accordance with relevant national regulations.

Grid-side new energy storage projects are generally located in load centers, areas with weak grid regulation capabilities, and areas where new energy consumption is limited. Projects with a power of no less than 50 MW and a capacity of no less than 100 MWh are encouraged.

Power-side new energy storage is planned by the investor based on the scale of new energy storage in each region and the needs of other power generation projects planned and constructed by the enterprise.

User-side new energy storage is planned by the investor based on their own needs.

04 Guizhou Development and Reform Commission issued the "Notice of the Provincial Development and Reform Commission on Optimizing and Improving Peak-Valley Time-of-Use Electricity Prices (Draft for Comments)" (May 16)

On May 16, the Guizhou Development and Reform Commission issued the "Notice of the Provincial Development and Reform Commission on Optimizing and Improving Peak-Valley Time-of-Use Electricity Prices (Draft for Comments)". Under the new adjustment, the midday period from 13:00 to 14:00 outside the winter season will be changed to off-peak electricity prices, while the flat-rate electricity prices, which previously included transmission and distribution prices, will now exclude transmission and distribution prices from the fluctuation range, meaning that the peak-valley electricity price difference will be reduced.

It clearly specifies that the scope of implementation includes: industrial and commercial users with two-part tariffs, centralized charging and swapping, and independent energy storage power station charging.

For industrial and commercial users, the flat-rate electricity price participating in the fluctuation is the on-grid electricity price (transaction electricity price or agency electricity purchase price), and the transmission and distribution price, system operation fee, government funds and surcharges, and on-grid line loss fee do not participate in the fluctuation.

05 Tianjin Municipal Commission of Industry and Information Technology, etc., issued the "Implementation Rules for Demand-Side Management of Electricity in Tianjin" (May 15)

On May 15, the Tianjin Municipal Commission of Industry and Information Technology, etc., issued the "Implementation Rules for Demand-Side Management of Electricity in Tianjin". The document proposes that electricity users in industries such as industry, communications, finance, and the internet, which have high requirements for power supply reliability and power quality, should reasonably configure new energy storage equipment according to system operation needs, release energy storage electricity during peak electricity consumption periods, and thereby reduce the pressure on peak-shaving and frequency regulation of the large power grid.

Encourage enterprises, parks, and electricity demand-side management service agencies and other market entities to actively promote the construction of rooftop photovoltaic power generation and the integrated application of photovoltaic buildings, improve the proportion of renewable energy consumption, and accelerate the demonstration application of new energy storage in multiple scenarios. Encourage electricity users to purchase renewable energy electricity to promote the flexible consumption of renewable energy.

The Municipal Bureau of Industry and Information Technology and district power management departments should promote the transformation of power grid operation methods to source-grid-load-storage interaction and multi-level and multi-zone coordinated control, encourage various market entities to participate in green electricity trading or purchase green certificates and use green electricity; encourage industrial enterprises and industrial parks to carry out the construction of green and low-carbon microgrids and integrated source-grid-load-storage systems.

Support industrial electricity users, large commercial complexes, hotels, public buildings and other groups of electricity users to actively participate in the construction of virtual power plants. Promote virtual power plant operators to participate in demand response and ancillary service electricity market transactions.

It applies to virtual power plants constructed and operated by units under the State Grid Ningxia Electric Power Company or self-built and uniformly accessed to the autonomous region's virtual power plant management platform by social operators.

Grid-connected electrochemical energy storage systems should meet the requirements of the grid connection design specifications for electrochemical energy storage power plants. They should be able to participate in peak regulation, frequency regulation, and voltage regulation of the power system, and possess functions such as active power response and control, inertia response and primary frequency regulation, damping control, voltage regulation and reactive power control, black start, on/off grid switching, grid-forming mode and grid-following mode switching.

Equipment technical requirements mainly include primary system equipment such as grid-connected energy storage units (energy storage batteries, grid-connected energy storage inverters, step-up transformers), reactive power compensation equipment, secondary system equipment such as dispatch automation and communication systems, relay protection and safety automation devices, and related auxiliary equipment.

Among them, under rated voltage, a single grid-connected energy storage inverter should be able to operate continuously at 110% of rated current; at 120% of rated current, the continuous operating time should be no less than 2 minutes.

After the energy storage power plant step-up substation has been started and put into operation, the energy storage unit has completed the phase check and load test, and the station has the conditions for grid connection testing, the on-site test for grid connection can be carried out. The grid-connected energy storage system should complete the grid connection test within 3 months of grid-connected operation.

07 The Development and Reform Commission of Guangxi Zhuang Autonomous Region solicits opinions on the "Implementation Rules of the Sustainable Development Price Settlement Mechanism for New Energy" and the "Implementation Plan for Deepening the Market-Oriented Reform of On-Grid Electricity Prices for New Energy in Guangxi Zhuang Autonomous Region".

Recently, the "Implementation Rules of the Sustainable Development Price Settlement Mechanism for New Energy in Guangxi Zhuang Autonomous Region" and the "Implementation Plan for Deepening the Market-Oriented Reform of On-Grid Electricity Prices for New Energy in Guangxi Zhuang Autonomous Region" were released. It is clearly stated that: the mechanism electricity price for distributed new energy is 0.4207 yuan/kWh, which is the Guangxi coal-fired benchmark price, and the proportion of electricity included in the mechanism is 100%. The mechanism electricity price for centralized new energy projects (excluding offshore wind power projects) is 0.324 yuan/kWh, with the electricity in 2025 already guaranteed by the 2025 medium- and long-term contract, and no mechanism electricity is set.

The implementation period of the mechanism electricity price is determined by the earlier of the year corresponding to the remaining reasonable utilization hours of the entire life cycle and the year corresponding to 20 years after commissioning.

The mechanism electricity price for incremental projects is formed through voluntary bidding by projects that have been put into operation and will be put into operation within the next 12 months and have not been included in the mechanism implementation scope, divided into wind power and photovoltaic categories. During the bidding, the selected projects are determined in ascending order of bids. The upper limit of the bidding is tentatively set at 0.4207 yuan/kWh, and the lower limit of the bidding can be initially determined by calculating the per-unit cost based on the construction cost of the most advanced power plants, and will be cancelled later as the situation warrants.

The scale of electricity included in the 2025 mechanism electricity is determined according to the proportion of non-market-based new energy in Guangxi in 2024, which is 33% (65% for the whole year) / 8% (16% for the whole year) according to the current non-market-based proportion of new energy in Guangxi.

The scale of newly added electricity included in the mechanism each year from 2026 onwards will be determined based on the completion of the renewable energy consumption responsibility weight and the user's affordability, but it should not be higher than the previous year. If the consumption responsibility weight is exceeded, the scale of electricity included in the mechanism in the following year will be appropriately reduced; if it is not completed, the scale of electricity included in the mechanism in the following year will be appropriately increased. The proportion of electricity applied by a single project to be included in the mechanism shall not exceed 80%.

The electricity included in the mechanism will be settled at the mechanism electricity price every month. The difference between the market transaction average price and the mechanism electricity price will be included in the system operating costs and shared among all industrial and commercial users.

Clarifies the way new energy participates in the market. Centralized new energy projects participate in the spot market in the way of "reporting quantity and price" or "reporting quantity without price", while distributed new energy can participate in the spot market as a price taker or be aggregated by aggregators.
