Core Viewpoint - The article emphasizes the urgent need to establish a new capacity pricing mechanism for energy storage in China to support the growing demand for renewable energy and ensure grid stability [2][8]. Group 1: New Energy Storage Capacity Support - The construction of a new power system in China is accelerating under the "dual carbon" goals, with significant increases in installed capacity for wind and solar energy. However, the intermittent and volatile nature of these energy sources poses challenges for grid capacity during peak load periods [6][8]. - In 2023, the State Grid's summer peak demand for new energy storage reached a maximum discharge capacity of 44.53 GW, equivalent to nearly three Three Gorges hydropower stations, providing substantial support during evening peak electricity usage [7]. Group 2: Need for Capacity Mechanism - The previous revenue models for independent energy storage included energy market revenue, ancillary service market revenue, capacity leasing revenue, and compensation revenue in some regions. However, recent policy changes have significantly impacted the demand and pricing space for capacity leasing, making it difficult for independent storage projects to cover their investment and operational costs [9]. - The current market rules do not fully reflect the value of new energy storage capacity, which could deter social capital investment and affect the stability of electricity supply and grid operations [9]. Group 3: Provincial Capacity Compensation Policies - Multiple provinces in China have begun to implement capacity compensation policies for new energy storage to address the lack of revenue mechanisms. These policies primarily adopt capacity compensation mechanisms, transitioning towards capacity market mechanisms in the future [12]. - Compensation methods vary across provinces, including: 1. **Discharge Volume Compensation**: Inner Mongolia has set a compensation standard of 0.35 CNY/kWh for 2025, while Xinjiang's compensation starts at 0.2 CNY/kWh in 2023, decreasing annually [13][14]. 2. **Capacity Compensation**: Hebei has established a capacity price of 100 CNY/kW for projects connected to the grid by May 31, 2024, with a gradual reduction thereafter [14]. 3. **Mixed Compensation**: Shandong and Gansu have implemented compensation mechanisms that consider both discharge and capacity [15][16]. Group 4: Summary and Outlook - The ongoing exploration of capacity compensation policies across various provinces is accumulating valuable practical experience for establishing a unified national capacity pricing mechanism. However, significant differences in compensation forms and fee structures exist, and many provinces have yet to implement such policies [17]. - It is recommended to adopt a phased and regional approach to policy implementation, considering local power supply and demand characteristics, to lay the groundwork for future market-based capacity trading [17].

Core Viewpoint - The article discusses the release of the "1+7" rule system (V4.0 version) for the Hebei Southern Power Grid electricity market, detailing revisions in market structure, spot trading, capacity leasing, ancillary services, and settlement mechanisms [2]. Market Structure and Participant Access - The Hebei Southern Power Grid electricity market includes three main trading segments: energy trading, ancillary service trading, and capacity trading. Energy trading is further divided into medium-long term and spot trading, while ancillary services include frequency regulation, ramping, and backup services [2]. - The scope of market participants has been expanded to include new entities such as energy storage companies, virtual power plants, aggregators, and smart microgrids. Specific technical parameters have been set for participation, such as a minimum independent storage charging power of 10 MW for frequency regulation [3]. Spot Market Trading Mechanism - The spot market operates on a model where generation side reports quantity and pricing, while the user side only reports quantity. The goal is to minimize system generation costs through centralized optimization [4]. - Pricing mechanisms involve node electricity prices for the generation side and a unified settlement point price for the user side. New entities must submit operational discharge curves for day-ahead market participation [4]. Medium-Long Term and Capacity Leasing Trading - Medium-long term trading requires segmented time periods, forming 24-hour segmented electricity and pricing, categorized into segmented trading and curve trading [5]. - Capacity trading is managed under the medium-long term market, with independent storage companies as lessors and renewable energy companies as lessees. Lessees must meet specific charging and discharging power and duration requirements [5]. Ancillary Services Market Operation - Currently, the Hebei Southern Power Grid primarily conducts frequency regulation auxiliary services and plans to establish a backup market. The frequency regulation market is organized after determining the day-ahead generation unit combination, using centralized bidding and marginal clearing [6]. - New market participants must declare parameters such as adjustment rate and rated power, with restrictions on their share of total frequency regulation rate demand set at a factor of k, currently defined as 0.3 [6]. Retail and Settlement Management - The retail market adopts a package system, divided into public and private packages, with various pricing methods including market linkage, fixed prices, or profit-sharing [7]. - Settlement for spot trading participants generally follows a "daily clearing, monthly settlement" model, with green electricity trading separating energy and environmental value settlements [8].
