The revenue per kWh exceeds 0.25 yuan/kWh. Hunan's electrochemical energy storage has earned more than 10 million yuan in the peak-shaving market.

As an auxiliary means to improve the flexibility of the power system and ensure power supply, new energy storage can play an important role in the process of building a new power system. In view of the current development situation of new energy storage in Hunan, the Hunan Energy Regulatory Office has started to conduct a survey on the development of new energy storage in Hunan in combination with the annual survey plan.

As the construction of the power market is not yet mature, the price support policy for new energy storage is imperfect, the construction standards are incomplete, and there is currently a lack of mature business models and effective profit-making means, so the enthusiasm of society to invest in new energy storage is not strong. It is reported that Hunan currently has an installed capacity of 190,000 kilowatts of electrochemical energy storage, all of which are centrally dispatched by power grid companies. The profit model is mainly to participate in the peak-shaving auxiliary service market and capacity leasing. From January to October 2022, Hunan's electrochemical energy storage revenue in the peak-shaving auxiliary service market exceeded 10 million yuan, and the charging electricity revenue exceeded 0.25 yuan/kWh.

The survey focused on the development costs, profit methods, dispatching and operation modes, and market participation methods of new energy storage in Hunan, focusing on four aspects. First, to understand the current status of new energy storage development in Hunan, cost-benefit, fair participation in the Hunan power market, and the role played in the safe and stable operation of the power grid; second, to analyze the main problems in the development of new energy storage in Hunan, and listen to the opinions and suggestions of the development and operation entities; third, based on the actual development of the Hunan power market, adhere to the market-oriented direction, promote the fair participation of new energy storage in the Hunan power market, and provide support for the optimization of the Hunan power market; fourth, report the survey results to the National Energy Administration and put forward opinions and suggestions on optimizing the development of new energy storage.
