In depth analysis of common problems in the construction of industrial and commercial energy storage power stations.

The domestic industrial and commercial energy storage market is currently in a golden period of vigorous development, with the market size continuing to expand. During this process, the safety and economy of energy storage project construction have always been the focus of attention for the industry and society. In order to ensure the successful implementation of energy storage projects, a deep understanding of the energy storage system and its design and construction process is particularly important. We are now sorting out and answering common questions in the design and construction of industrial and commercial energy storage power stations, providing reference and inspiration for everyone.

What are the site requirements for industrial and commercial energy storage power stations?
1) The venue is located outdoors, preferably away from office spaces and dense crowds, and there are no hazardous chemical warehouses within 10 meters;
2) Choose a location that is close to the access point distribution room (recommended within 30m) and convenient for cable layout;
3) Consider a hardened site that is convenient for transportation, lifting, and load-bearing. The actual project needs to reserve safety protection passages and isolation passages according to the requirements of the local fire department;
4) The user's internal site or adjacent locations should be adjacent to the enterprise fence, and there should be no public roads, other buildings, or isolation between them.
What information does the owner need to provide for the installation of commercial and industrial energy storage power stations?

Before installing industrial and commercial energy storage power stations, the owner needs to provide information including the corresponding project's corporate property rights, electricity load, electricity usage situation, and electrical equipment. Technicians need to calculate the energy storage construction capacity based on the enterprise's electricity load data, average/maximum load power, transformer capacity, and load data.

In addition, the owner is required to provide information such as the primary power system diagram, factory floor plan, distribution room layout, cable routing, etc., to determine the construction location of the energy storage power station and the location of the connected transformer.

What approval procedures are required for the construction of industrial and commercial energy storage power stations?

The installation of industrial and commercial energy storage power stations requires project registration on the website of the local Development and Reform Bureau and application for power access approval from the local power company. In addition, according to specific regulations in different regions, other processes such as fire design review, environmental impact assessment report, and case evaluation report may also be required. Therefore, before starting the project, it is necessary to have a deep understanding of the acceptance and audit standards for local industrial and commercial energy storage projects, and to prepare for the budget and preparations in the early stages of the project. The above procedures are the responsibility of the integrator, and the owner only needs to cooperate in providing the required materials.

What are the construction processes for industrial and commercial energy storage power stations? How long does the construction period take?
The construction process of industrial and commercial energy storage power stations includes capital survey, scheme design, project filing, drawing design, access approval, construction, equipment commissioning, and grid connection acceptance. The overall project construction period is determined by the time required for different project processes. The construction period of Hongzheng Industrial and Commercial Energy Storage Project is generally about 15 days to 1 month for low-voltage connection and about 2.5-3 months for high-voltage connection; When connecting to the grid, a certain period of power outage is required according to safety requirements, which can be carried out in different areas for installing grid cabinets. The power outage time is about 4 hours, and the specific time depends on the situation.
Will energy storage power stations increase the basic electricity bill for the owner?
The basic electricity bill of electricity consuming enterprises can be charged in two ways: capacity based billing and demand based billing. In the case of capacity billing,
