China Electric Power Spot System: Summary, Practice & Analysis
This document provides a comprehensive summary and analysis of China's electric power spot system and its practical implementation. It begins by outlining the electricity market reform process, emphasizing the need for dynamic balance through spot pricing. The spot price is determined by time-sharing supply-demand balance, with significant fluctuations observed in Shanxi province from 2021 to 2023, where monthly averages varied by up to 83% and daily averages by 500%. The future trends include high fluctuation risk, high transaction frequency (up to 1524 windows annually), financialization of transactions, trading specialization, coal-electricity linkage, and market nationalization. The document then reviews differentiated practices across provinces, covering user-side, new energy, and energy storage declarations, as well as medium-long term curve and time-sharing systems. Virtual power plants are highlighted as emerging entities that shift from load to generation based on price signals. Case studies include electricity sales companies, large users, independent energy storage, new energy, and thermal power companies, each optimizing costs or revenues through refined trading strategies. Opportunities for users, virtual power plants, and energy storage in spot trading are discussed, focusing on cost reduction, risk control, and management optimization.
