Now, if the industrial and commercial energy storage is already a weapon for many enterprises to reduce costs and increase efficiency, for some ordinary users, they also want to enter the industrial and commercial energy storage and participate in investment. What are the benefits of investing in industrial and commercial energy storage, and in what cases is it suitable to invest? The following is an analysis one by one.
1, reduce the cost of electricity
Peak shaving and valley filling is one of the scenarios in which industrial and commercial energy storage is applied on the household side. In China, the peak-valley price difference of industrial and commercial electricity is large, with the energy storage system charging during the low period and discharging during the peak period in order to get arbitrage through the peak-valley price difference and reduce the electricity cost of enterprises. In addition, different provinces in China have also formulated various subsidies for each kilowatt-hour of electricity according to system capacity and discharge capacity, as well as investment subsidies, which will increase the income of industrial and commercial energy storage. The specific income situation should be calculated according to local policies, peak and valley electricity prices, and installed capacity.
2. To provide stable and reliable power
The energy storage system can smooth the load fluctuation of the distribution network, which is especially important for enterprises and facilities with high requirements for power quality. To those with high demand for power stability, when power fluctuation occurs, it will do great harm to enterprise production. Therefore, choosing investment in industrial energy storage is able to meet the needs for smoothing out grid fluctuations.
3. Response to grid demand
In the peak summer and peak winter, the power grid’s load increases and the energy storage system can take an active part in the interaction on the grid and obtain a higher compensation. In other words, simply stated, the response of power grid demand refers to the power demand of a power grid. The user side applies for the response power, and when the response time reaches the response demand of the applied power, the corresponding high subsidy can be obtained. It is also an important way for energy storage systems to gain income.
4. Dynamic capacity
In some cases of overload for the old transformer, users do not want to spend too much money reinstalling or transforming the equipment. When upgrading the system, the energy storage system can expand the transformer capacity virtually through discharge, and reduce the cost of distribution equipment and transformer transformation.
5. To reduce the peak demand of an enterprise
Real-time gathering of the transformer’s true power can be done through the energy storage system. It will automatically release the demand when the power reaches maximum demand, reducing the basic charge of electricity. Some customer electricity statistic items are billed according to their peak demand, the peak demand refers to the average electric power of a customer during some duration (15 minutes just now in China execution), its biggest indication value is recorded for the peak demand value in this accounting cycle, thus, the peak cuts in energy storage installation, could help the customers to decrease costs.
6. To improve emergency backup capacity
The emergency power backup at important places such as enterprises and public institutions is to avoid the occurrence of power outages at important moments, which will use energy storage system backup to achieve seamless switching when the power grid fails or there is a power outage, in order to ensure the continuous operation of important enterprise loads. At present, these benefits not only allow enterprises to save costs on all sides but also improve power supply stability and reliability in an important investment direction, both industrially and commercially.
