Core Viewpoint - The article outlines the "Hebei Province 2025 Power Load Management Work Plan," which aims to address power supply shortages and ensure stable operation of the power grid in Hebei Province, particularly during peak demand periods in summer and winter [7][9]. Supply and Demand Situation - In summer, the maximum load for the Hebei South Grid is expected to reach 55 million kW during peak hours, with a supply gap of approximately 3 million kW during the evening peak. The Hebei North Grid is projected to have a maximum load of 32 million kW in the morning and 31 million kW in the evening, maintaining a balanced supply-demand situation. In extreme conditions, the supply gap could increase to 5 million kW for the South Grid and 473 million kW for the North Grid [3][9]. - In winter, the maximum load for the Hebei South Grid is anticipated to be 51.5 million kW in the morning and 49 million kW in the evening, with a supply gap of about 150,000 kW. The North Grid's maximum load is expected to be 33 million kW in the morning and 34 million kW in the evening, also maintaining a balanced supply-demand situation. In extreme conditions, the supply gap could rise to 350,000 kW for the South Grid and 707,000 kW for the North Grid [3][9]. Key Tasks - The plan emphasizes comprehensive energy-saving strategies, including reducing energy consumption in landscape lighting and air conditioning, promoting energy efficiency in industrial enterprises, and encouraging residents to participate in energy-saving activities [11][12]. - Industrial enterprises are encouraged to implement flexible maintenance schedules to reduce peak load during high-demand periods, and users with energy storage systems are advised to optimize their charging and discharging strategies [12][13]. - The plan aims to expand the demand response resource pool by promoting the inclusion of flexible load resources such as energy storage, cold chain logistics, and self-generating power plants [14][15]. Load Management Indicators - The plan establishes load management indicators for both the Hebei South and North Grids, detailing various warning levels based on the percentage of supply gap, with specific thresholds for different regions [18][20]. - For instance, in Shijiazhuang, the indicators range from a 5% gap (36,000 kW) to a 30% gap (307,000 kW), while in Tangshan, the range is from a 5% gap (75,000 kW) to a 30% gap (451,000 kW) [18][20]. Implementation Requirements - The plan mandates strict adherence to load management measures, including timely notification to power users about load management strategies and the establishment of internal operational plans [21][24]. - It also emphasizes the need for periodic reviews and adjustments to the load management strategies based on the execution outcomes and any emerging challenges [25].
