Constructing a new type of power system with new energy as the main body is a major strategic deployment made by the Party Central Committee for the development of China’s energy and power industry in the new development stage，guided by the new development concept. Improving the ability to adjust the power load and strengthening the collaborative interaction between the supply and demand sides are inevitable requirements for accelerating the construction of a new power system with new energy as the main body. This paper selects 21 key industries and 129 companies in Henan Province to conduct an in-depth investig-ation and analysis of industry power consumption characteristics and adjustable capabilities. Based on big power data，this paper systematically studies the power load capacity of key industries in the province by season and time period. Regulating capacity status and 2025 scale potential，combing the status quo of load-side resources participating in power system regulation and related policies，and proposing market-oriented implementation paths and related policy recom-mendations. The research conclusions are of positive significance for promoting the province’s load-side resources to participate in the operation of the power market，improving the overall flexible adjustment capability，promoting the construction of a new power system，and serving the achievement of carbon peak and carbon neutral goals.
