The “14th Five-Year Plan” period is the key period to accelerate the construction of new power system and promote the realization of “carbon peak and carbon neutral”. As an important technology and basic equipment to support the new power system，new energy storage can play the role of “electrical power warehouse”，realize the division of power production and consumption in time and space，and provide a variety of services for system operation such as peak regulation，frequency regulation，standby and black start，which is an important means to enhance the safety，flexibility and economy of power system. It is an important means to enhance the security，flexibility and economy of power system，which is of great significance to ensure reliable power supply，promote green energy transformation and build modern energy system. This paper systematically compares the policy requirements for the development of new energy storage，addresses the problems of insufficient peaking capacity of Henan’s power system and high pressure on power security，calculates the overall scale demand for new energy storage in the province，studies the energy storage configuration strategy and layout plan，and puts forward countermeasures and suggestions to promote the development of new energy storage.
