The cost of building energy storage power station mainly includes the following aspects:
1、Equipment and material costs：The equipment cost of energy storage power stations is the main component of construction costs. This includes energy storage devices (such as battery packs, supercapacitors, compressed air energy storage devices, etc.), inverters, transformers, cables, control systems, etc. In addition, there is the cost of auxiliary equipment and various materials, such as brackets, cooling systems, protective equipment, etc. The quality and quantity of these equipment need to strictly comply with the operating scale of the power station.
2、Building and land costs: In the early stage of the construction of energy storage power stations, suitable operating sites are required, and the size of the site must meet the operational needs of the power station. Energy storage power stations usually require the construction of corresponding buildings and infrastructure, including power plant buildings, control rooms, distribution rooms, cable tunnels, etc. In addition, land acquisition and preparation are also a part of the cost.
3、Engineering and construction costs: The engineering and construction costs of energy storage power stations include engineering design, civil engineering, equipment installation, power access, etc. This involves the costs of engineers and technicians, as well as the costs of construction teams and equipment. In order to ensure normal operation, it is necessary to carry out relevant spatial planning work, which will also bring corresponding convenience to later operations.
4、Operation and maintenance costs: The operation and maintenance costs of energy storage power plants include personnel salaries, equipment maintenance, system monitoring and management, insurance costs, etc. These costs are usually long-term and require consideration of factors such as battery replacement, equipment maintenance, and system upgrades. In the process of market operation, there will be certain operating costs, including the costs incurred for operational development and promotion, and ensuring the brand's visibility and advantages in the market.
5、Environmental impact assessment and monitoring costs: Environmental impact assessment is required during the construction of energy storage power plants to ensure compliance with environmental requirements. In addition, it is necessary to establish an environmental monitoring system to continuously monitor the impact of power station operation on the environment.
6、Regulatory and approval costs: The construction of energy storage power stations needs to comply with relevant regulations and approval requirements. This involves various approval fees, license applications, security assessments, etc.
In summary, in the calculation process of energy storage construction costs, it is necessary to consider the decreasing proportion of total construction costs, unit energy construction costs, and energy storage capacity parameters.
