The National Electricity Market of Australia (NEM), which manages the energy supply of six Australian states, including New South Wales, believes that with the decline of solar power generation and the increase of nighttime demand, peak power plants will provide about 3 to 4 hours of electricity every night from 6pm.
The Clean Energy Commission of Australia (CEC) said that the battery energy storage system can provide rechargeable power during this period of time. In view of the declining charging costs of solar and wind power generation facilities, the declining battery costs and the increasing efficiency, Australia has no sufficient economic reason and necessity to build new natural gas power plants。
Solar battery storage system cost australia？It is found that the total capacity leveling cost (including capital cost, fixed operation and maintenance costs and various operation and maintenance costs) of a battery energy storage system with a continuous discharge time of 2 hours is about AUD 119/kW/year, the total capacity leveling cost of a 4-hour battery energy storage system is about AUD 197/kW/year, and the total capacity leveling cost of an open cycle gas turbine power plant with the same installed capacity is about AUD 203/kW/year. At the same time, based on the levelized energy cost (LCOE), the 2-hour battery energy storage system is AUD195/kW/year, the 4-hour home battery energy storage system is AUD156/kW/year, and the open cycle gas turbine power plant is AUD234/kW/year，
