Guizhou: independent energy storage spot market charging and discharging prices are adopted node time-sharing tariffs
August 18, Guizhou Provincial People's Government issued "Guizhou Province, the new energy storage to participate in power market trading implementation plan (draft)". It is clear that independent energy storage can carry out medium- and long-term transactions with other market players, and in charging time is regarded as power users purchasing electricity, and in discharging time is regarded as power generation enterprises selling electricity. Independent energy storage spot market charging and discharging prices are used in the node of the time-sharing tariff.
The participation of new type of energy storage in spot electricity energy trading explicitly requires that the independent energy storage of the whole amount of electricity to participate in the spot market clearing, with the conditions to participate in the way of quoted quantity, without the conditions to consider the use of other ways to participate in the way of quoted quantity without quotes.
Power-side energy storage connected to the grid within the metering gate of a power generation enterprise maintains the operation mode with the power generation enterprise as a whole, and the corresponding power generation enterprise as a whole participates in power market transactions, as well as the specific requirements for power-side energy storage to participate in the transaction process of electric energy transactions, auxiliary service transactions and transaction settlements.
User-side energy storage connected to the grid within the metering gateway of the power user, maintaining the operation mode with the power user as a whole, the overall participation of the corresponding power user in the market transactions, as well as the user-side participation in the transaction process of electric energy transactions, demand response transactions and transaction settlement of the specific requirements.
Shanxi: pumped storage as the main direction of energy storage development, source network load three ends of the rational layout of new energy storage
The morning of August 14, the Shanxi Provincial Government Information Office "to promote the green transformation of the energy industry" special conference, Shanxi Province, deputy director of the Energy Bureau, spokesman Hou Bing let said, the next step will be pumped storage as the main direction of energy storage development, in the source, network, load the three ends of the reasonable distribution of new energy storage, the formation of pumped storage is the main new energy storage for the supplementary storage and regulation system. Supplementary storage and regulation system.
Yunnan FM market rules: compensation cap of 8 yuan / MW, independent energy storage, virtual power plant can participate!
On 16 August, Yunnan Energy Supervision Office issued Yunnan FM Auxiliary Service Market Operation Rules (2023 Exposure Draft). Independent energy storage power station can participate in the market as a third party independent subject, including energy storage devices, energy storage power station and other third party auxiliary service providers can also serve as the market subject. It is clarified that independent energy storage power stations only include electrochemical energy storage power stations.
According to the opinion draft, the lower limit of rated power access for independent energy storage power stations is 30MW, and the lower limit of declared value of FM capacity for third-party independent subjects is 5MW.
Yunnan FM market compensation is divided into two forms: FM mileage compensation and AGC regulation capacity compensation.
The AGC regulation capacity compensation standard of the generation unit that has not won the bid and has not been called up in the Yunnan FM market is in accordance with RMB 4/MWh, and the AGC regulation capacity compensation standard of the generation unit that has won the bid or has been called up due to the need for grid security is compensated in accordance with RMB 5/MWh.
The upper limit of the declared price for FM mileage is RMB 8/MW, and the lower limit of the declared price for FM mileage is RMB 3/MW. Market participants should set default values for the FM mileage declaration price of their generation units; if no default value is set, the lower limit of the FM mileage declaration price will be the default. The smallest unit of the declared price is RMB 0.1/MW.
Gansu: Encourage differentiated allocation of energy storage and clarify the distribution of revenue from energy storage power stations!
On 15 August, Gansu Development and Reform Commission issued a "notice on matters relating to the configuration of energy storage for centralised new energy projects in Gansu Province".
The document puts forward, encourages new energy projects to differentiate the configuration of new energy storage by region: "14 five" the first batch of wind power projects continue to be implemented in accordance with the previous energy storage configuration requirements. Hexi region (Jiuquan, Jiayuguan, Jinchang, Zhangye, Wuwei) at least 10% of the installed capacity of the power station configuration, the other regions at least 5% of the installed capacity of the power station configuration, energy storage facilities are not less than 2 hours of continuous energy storage.
The second batch of wind power projects in the "14th Five-Year Plan": the west region (Jiuquan, Jiayuguan, Zhangye, Jinchang, Wuwei) is allocated with 15% of energy storage, with a continuous duration of 4 hours; the central and eastern region (Lanzhou, Baiyin, Tianshui, Pingliang, Qingyang, Dingxi, Longnan, Gannan, Linxia, Lanzhou New Area) is allocated with 10% of energy storage, with a continuous duration of 2 hours. .
In addition, the document also specifies the revenue allocation of the energy storage power station: shared energy storage gained by the new energy enterprises involved in the construction of their own allocation; third-party enterprise-led construction of shared energy storage, revenue allocation and new energy generating enterprises to determine the negotiation.
Guangzhou: strive for new energy storage revenue in 2027 to reach 100 billion yuan!
On 15 August, Guangzhou Municipal People's Government issued the "Implementation Opinions on Promoting the High-Quality Development of New Energy Storage Industry". According to the Guangzhou Municipal Bureau of Industry and Information Technology disclosure, Guangzhou is currently under construction in the new energy storage project 11, with a total investment of nearly 40 billion yuan, the output value can exceed 100 billion yuan after reaching production.

Among them, in the transmission line corridor resources, substation site resources tense power supply area reasonably allocate a certain scale of new energy storage, encourage to meet the requirements of grid security, adapt to the premise of grid planning, relying on the existing substation and the surrounding land construction of energy storage power station. Support distributed small-capacity energy storage in urban villages power management, remote rural areas and power sensitive users power management and other scenarios.
India's National Thermal Power Corporation to pilot gravity energy storage project
Recently, India's National Thermal Power Corporation (NTPC) issued a tender for its Talcher thermal power plant in Orissa, which includes the design and installation of the thermal power plant as well as the commissioning of the mechanical energy storage project, which will become a demonstration project.
India's National Thermal Power Corporation is said to be building a mechanical energy storage project at its Talcher thermal power station in Orissa, the tender reads, adding that the system will be designed to convert electrical energy into potential energy for storage, and then convert it back into electrical energy as needed, so the odds are that it will be a gravity energy storage project.
The National Thermal Power Corporation of India said the existing structure at the Talcher thermal power station was about 50 metres in height, and the structure was refitted with a mechanical energy storage system.
