2、 Strengthen the construction of peak shaving capacity
(1) Focus on improving the peak shaving capability of supportive power sources. Deepen the flexibility transformation of coal-fired power units, and achieve “all that should be improved” by 2027 for existing coal-fired power units. In areas with a high proportion of new energy and insufficient peak shaving capacity, exploring deep peak shaving of coal-fired power units while ensuring safety, with a minimum power generation output below 30% of the rated load. In areas with guaranteed gas sources, affordable gas prices, and high demand for peak shaving, a moderate number of peak shaving gas and electricity projects should be laid out, fully leveraging the advantages of rapid start and stop of gas units, and improving the system’s short-term peak shaving and deep regulation capabilities. Explore nuclear power peak shaving and study the feasibility of nuclear power safety participating in power system regulation.
