Core Viewpoint - The establishment of the "1+6" foundational rule system for the electricity market in China facilitates the transition from "hard connections" to "soft connections," addressing key issues such as renewable energy consumption, inter-provincial barriers, and market vitality [2][5]. Group 1: Development of the "1+6" Rule System - The "1+6" foundational rule system aims to extend the electricity market in both time and space dimensions, promoting long-term contracts and shorter trading intervals [3][4]. - In the time dimension, long-term contracts will stabilize market supply and price expectations, while shorter trading intervals will enhance market responsiveness to trading demands [3][4]. - In the spatial dimension, the system promotes a unified national electricity market and supports the development of micro-markets, accommodating new entities like energy storage and virtual power plants [4][5]. Group 2: Importance of a Unified Electricity Market - The establishment of a unified electricity market is crucial for enhancing infrastructure connectivity and regulatory coherence, allowing for the free allocation of renewable resources across the country [5][6]. - The foundational rule system addresses disparities in market models, trading sequences, and organizational structures that have emerged from local explorations, ensuring a cohesive national framework [6][7]. - It resolves core contradictions in market operations, clarifying the roles of inter-provincial and intra-provincial markets, thus laying a solid foundation for a deeper integration of the national market [7]. Group 3: Balancing Security and Marketization - Ensuring reliable electricity supply is fundamental to the construction of a unified electricity market, while market mechanisms are essential for discovering electricity prices [9][10]. - The long-term market plays a foundational role in stabilizing supply and price expectations, benefiting both power generation companies and large electricity consumers [10]. - The spot market reflects real-time supply and demand dynamics, providing price signals that encourage efficient energy use and generation [10][11]. Group 4: Auxiliary Services and Capacity Market - The auxiliary services market is essential for maintaining system stability, incentivizing various resources to participate in system regulation [11]. - A capacity market mechanism will be established to ensure long-term system reliability, compensating resources that support stable operations [11].
