山西加快建设新型能源体系（奋勇争先，决战决胜“十四五”）

Core Viewpoint - Shanxi province is advancing its energy development path by integrating traditional coal power with renewable energy sources, aiming for cost reduction and pollution mitigation while ensuring energy security and stability [1][2][3][4]. Group 1: Energy Supply and Integration - Shanxi has achieved over 50% of its installed capacity from renewable energy, necessitating enhanced support from traditional coal and thermal power [1]. - The province is implementing flexible modifications to coal power units to improve peak load capacity, ensuring that electricity supply can meet demand fluctuations [2]. - A new 20 MWh thermal storage system has been introduced to enhance the peak load response of coal-fired power plants, allowing for better management of energy supply during peak and low demand periods [2]. Group 2: Transmission and Stability - Shanxi is addressing the volatility of renewable energy by promoting integrated development between traditional and renewable energy sources, facilitating the absorption of renewable energy [3]. - The province has established a robust transmission network, including ±800 kV ultra-high voltage lines, capable of delivering 270 billion kWh of clean electricity annually to the Beijing-Tianjin-Hebei region [3]. - The energy transmission system is designed to support a maximum delivery capacity of 36 million kW, enhancing the stability and reliability of energy supply [3]. Group 3: Market Mechanisms - The real-time electricity market in Shanxi allows for dynamic pricing, where coal power plants adjust output based on the availability of renewable energy, optimizing market space for green energy [4]. - Over 21,000 market participants are engaged in the electricity spot market, which serves as an effective mechanism for energy dispatch and pricing [4]. - Shanxi aims to continue integrating energy security with green development, contributing to national energy security and the establishment of a strong energy nation [4].
