National Policies and News

01 The National Energy Administration Releases the "Implementation Rules for Issuance of Green Power Certificates for Renewable Energy (Trial)" (Draft for Comments)

On March 26, the National Energy Administration released the "Implementation Rules for Issuance of Green Power Certificates for Renewable Energy (Trial)" (Draft for Comments). It states that green certificates will not be issued for the electricity discharged from energy storage facilities of renewable energy power generation projects. Projects should separately measure the charging and discharging electricity of energy storage facilities. For projects currently without independent metering devices, green certificates will be issued based on the principle of deducting off-grid electricity from on-grid electricity.

For integrated projects including various power generation types and energy storage devices, such as source-grid-load-storage, wind-solar hydrogen production (ammonia/alcohol), and renewable energy replacement of coal-fired self-owned power plants, the project owner should commission the power grid enterprise or other legally designated metrology and verification institutions to separately meter the different renewable energy power generation facilities.

02 The Central China Regulatory Bureau of the National Energy Administration Releases the "Operational Rules for the Hubei, Jiangxi, and Chongqing Power Frequency Regulation Ancillary Service Market"

On April 2, the Central China Regulatory Bureau of the National Energy Administration released the "Operational Rules for the Hubei, Jiangxi, and Chongqing Power Frequency Regulation Ancillary Service Market". New operating entities include energy storage enterprises, virtual power plants, and load aggregators. New energy power generation facilities with energy storage that are not independently controlled by dispatch can participate in the frequency regulation market as a frequency regulation unit in the form of wind-storage or solar-storage.

The comprehensive frequency regulation performance coefficient K of the frequency regulation unit participating in providing frequency regulation ancillary services should not be less than 0.6. If the frequency regulation unit fails to reach 0.6 for eight consecutive successful bidding periods on the same operating day due to its own reasons, it will not receive frequency regulation mileage compensation for that day.

The upper and lower limits of the frequency regulation mileage reported Price are tentatively set at 15 yuan/MW and 5 yuan/MW respectively. Frequency regulation units that have received capacity electricity charges but have not actively participated in market bidding will automatically participate in market bidding, with a default quotation of 5 yuan/MW.

Before the continuous operation of the power spot market, the generation-side operating entities (including the on-grid electricity of new energy storage) will fully share the cost, and the entities participating in the sharing among generation-side operating entities will remain consistent with the sharing entities in the Central China region's "two detailed rules".

The "Rules" clarify that the adjustment process of wind-storage, solar-storage, wind-solar renewable energy less than 10 seconds, new energy storage less than 3 seconds, and new operating entities such as virtual power plants and load aggregators less than 30 seconds is considered random fluctuation and will not be included in the adjustment process statistics, assessment, and compensation.

According to the operational parameter table of the frequency regulation ancillary service market, the total successful bid capacity ratio of new operating entities is 30% for Hubei, 30% for Jiangxi, and 30% for Chongqing.

0 3 The Northeast Regulatory Bureau of the National Energy Administration Releases the "Operational Rules for the Northeast Power Ancillary Service Market (Draft for Comments)"

On March 31, the Northeast Regulatory Bureau of the National Energy Administration released the "Operational Rules for the Northeast Power Ancillary Service Market (Draft for Comments)". The document clarifies that the upper limit of the real-time deep peak-shaving transaction Price for each province (region) is the on-grid Price of the local parity renewable energy project. Specifically, it is 0.3749 yuan/Wh for Liaoning, 0.3731 yuan/Wh for Jilin, 0.3740 yuan/Wh for Heilongjiang, and 0.3035 yuan/Wh for Eastern Mongolia.

Northeast power peak-shaving ancillary services are divided into basic obligation peak-shaving ancillary services and paid peak-shaving ancillary services. The operating entities of the power ancillary service market are grid-connected power plants in the Northeast region, including thermal power plants, wind farms, photovoltaic power stations, and nuclear power plants.
