H Battery Energy Storage Power Plant Investment Benefit Analysis

The development of battery energy storage is an important means to achieve the goal of carbon peaking and carbon neutrality,and provides an effective solution to make up for the short board of energy and electricity,which is of great significance to guarantee energy security and promote the development of industrial chain.Battery energy storage is an emerging energy storage method,with the advantages of short construction cycle,flexible arrangement,fast response,and various application scenarios.The large-scale operation of battery energy storage power plant reduces the investment in power supply and power grid on the one hand,and ensures the smooth operation of power grid,on the other hand,it improves the consumption of clean energy and plays an important role in slowing down the abandonment of wind and light by renewable energy.Large-scale grid-side battery storage power plants have been deployed on a large scale and play an important role,but the construction cost and operation cost of battery storage power plants still have no way to be channeled in a reasonable and scientific way.In order to study the investment income of large-scale battery energy storage power plants,the economics of battery energy storage power plants are analyzed from three aspects:commercial operation mode,investment and construction costs and economic benefits.In the peak-to-valley price difference,auxiliary peaking services and other profit models to H battery storage power plant as an example of analysis.The article compares the benefits of grid-side battery energy storage power plants with the cost of the entire life cycle of the battery by analyzing the net present value,static payback period,and embedded payoff rate to evaluate their cost effectiveness.The results show that under the existing market and policy conditions,the application of a single price for battery storage power plants cannot recover the investment cost,and the price mechanism and price subsidy should be improved to actively promote the participation of energy storage in the spot market and improve the income of storage power plants in order to promote the development of battery energy storage.
