The difference between industrial and commercial energy storage and large-scale storage.
At present, the global renewable energy generation is constantly increasing, but due to its high volatility, it is difficult to effectively and stably supply. The application of energy storage technology provides a good solution to this problem and has received attention from countries around the world, continuously introducing relevant policies to promote the development of energy storage. For example, the Energy Storage Investment Tax Credit (ITC) introduced by the United States, the Green New Deal in Europe, and the energy storage development plans of various governments in China have all played a positive role in promoting the development of the energy storage market.
According to the International Energy Agency (IEA), in order to promote the rapid deployment of new solar photovoltaics and wind power and achieve triple growth in renewable energy, global energy storage capacity must increase sixfold to 1500GW by 2030. In the net zero emissions (NZE) scenario by 2050, battery energy storage will account for 90% of energy storage growth, and by 2030, it will increase 14 times to 1200GW. Battery energy storage shows broad development prospects in the global energy storage field.
Energy storage can be divided into power side, grid side, and user side energy storage according to application scenarios. Among them, power side and grid side energy storage are also known as pre meter energy storage or large-scale energy storage, while user side energy storage is also known as post meter energy storage. User side energy storage is divided into industrial and commercial energy storage and household energy storage. At present, large-scale energy storage still holds the majority of the global energy storage market share. However, in the past two years, industrial and commercial energy storage in user side energy storage has been on the rise. In 2022, the global industrial and commercial energy storage growth rate was only 14.58%, but by 2023, the newly installed capacity will reach 1.8GW, a year-on-year increase of 115%. The global industrial and commercial energy storage market is mainly concentrated in China, the United States, and Europe represented by Germany. Weilan New Energy is a high-tech enterprise that has been focusing on the research and development, production, sales, and service of industrial and commercial battery energy storage technology and products since its establishment in 2019. In addition to the domestic market, Weilan New Energy has successfully penetrated multiple European markets and registered local companies in Europe.
Next, this article will explain the difference between industrial and commercial energy storage and large-scale storage.
1、 Definition of Industrial and Commercial Energy Storage:
Industrial and commercial energy storage systems are mainly used in industrial and commercial places, including factories, office parks, shopping malls, hotels, etc. Compared to 'large storage', it has a smaller capacity and mainly adopts a single cabinet form, highly integrated, and modular design.
1. Application scenarios:
(1) Peak shaving and valley filling: store electricity during periods of low electricity prices and discharge during periods of high electricity prices to save electricity costs.
(2) Backup power supply: In the event of a power grid failure, provide emergency backup power to ensure the continuity of production and operation.
(3) Improving the utilization rate of renewable energy: Combining with renewable energy such as photovoltaics and wind power, storing excess electricity, and improving energy utilization efficiency.
(4) Load management: Balance the electricity load within the park and reduce the pressure on the power grid.
2. Characteristics:
(1) Moderate scale: The capacity of energy storage systems typically ranges from several hundred kWh to several MWh.
(2) Flexible deployment: The system design is flexible and adaptable to various power and capacity requirements.
(3) Cost effectiveness: By saving electricity costs, providing backup power, and other means, investment returns can be quickly achieved.
2、 Definition of large-scale energy storage:
Large scale energy storage systems usually refer to energy storage projects with large capacity, mainly used for power grid level power regulation and stability, serving power companies and large-scale power infrastructure. The product structure is mainly based on containers, divided into DC side systems and medium voltage converter systems.
1. Application scenarios:
(1) Power frequency regulation: Quickly respond to fluctuations in grid frequency and maintain grid stability.
(2) Peak shaving and valley regulation: providing power support during peak demand periods and storing excess power during low demand periods.
(3) Backup power supply: providing large capacity backup power in the event of large-scale power outages or power shortages.
(4) Renewable energy grid connection support: Smooth out the output fluctuations of renewable energy such as wind power and photovoltaics, and promote their large-scale grid connection.
2. Characteristics:
(1) Large scale: Energy storage systems typically have capacities ranging from tens of MWh to hundreds of MWh.
(2) Complex system: The design and operation are complex, requiring consideration of various factors such as power grid demand and scheduling strategies.
(3) High investment: The initial investment is relatively large, but with technological progress and economies of scale, the cost gradually decreases.
3、 Summary:
Industrial and commercial energy storage differ from large-scale storage in terms of application scenarios, system scale, functions, and characteristics. Industrial and commercial energy storage focuses on meeting the electricity needs of specific locations, providing cost-effectiveness and operational support, while large-scale energy storage mainly serves grid level regulation and stability, solving larger scale power supply and demand balance problems.
With the continuous advancement of energy storage technology and the decrease in costs, industrial and commercial energy storage, as well as large-scale energy storage, will play an increasingly important role in jointly promoting global energy transformation and sustainable development.
