Dyness Knowledge | The difference between C&I reserves and large storage

In the wave of global energy transformation, energy storage technology, as a key supporting means, is gradually becoming the focus of attention of enterprises and policymakers. Among the many energy storage solutions, industrial and commercial energy storage (hereinafter referred to as "C&I storage") and large-scale energy storage (hereinafter referred to as "large storage") are two common application forms. This article will compare and analyze the differences between commercial and industrial storage and large-scale storage from multiple dimensions to help readers better understand the characteristics and applicable scenarios of these two energy storage systems.

Scale and Capacity

First, in terms of scale and capacity, the main difference between industrial and commercial storage and large storage lies in the objects they serve and the scale of demand. Industrial and commercial storage usually serves industrial and commercial users, and its scale is relatively small, with a capacity generally ranging from a few kilowatts to several megawatts. Large storage, on the other hand, serves a wider range of power grids and energy markets, and its scale is larger, with a capacity usually ranging from tens of megawatts or even higher.

Application Scenario

There are also obvious differences in the application scenarios of C&I storgae and large storage. C&I are mainly used for:

1. Utilization of peak-valley electricity price differences: By storing electricity during low-price periods and using or selling it during peak periods, the company's electricity costs can be reduced.

2. Demand-side management: The energy storage system can be used to adjust the company's electricity demand, achieve demand response, and improve the flexibility of energy use.

3. Renewable energy integration: Help companies better utilize renewable energy such as solar energy and wind energy to improve energy self-sufficiency.

Large storage are more often used for:

1. Grid frequency regulation: Maintain grid stability by quickly responding to grid frequency changes.

2. Grid peak shaving and valley filling: Store electricity when there is excess power supply, release electricity when there is a power shortage, and balance grid supply and demand.

3. Cross-regional power dispatching: Realize power complementarity and optimal configuration between different regions.

Technical route

In terms of technology, although both industrial and commercial storage and large-scale storage are based on electrochemical energy storage technologies such as lithium-ion batteries and lead-acid batteries, there may be differences in specific technology selection and system integration. Industrial and commercial storage may focus more on system flexibility and customization to meet the specific needs of different companies, while large-scale storage may focus more on system reliability and scale to meet the needs of large-scale power grid operation.

Business model

Industrial and commercial storage and large storage also differ in their business models. The business model of industrial and commercial storage may include direct purchase, leasing, cooperation with energy service companies, etc., and it focuses more on providing personalized energy solutions for enterprises. The business model of large storage may involve power market transactions, demand response, power auxiliary services, etc., and it focuses more on realizing value in a wider energy market.

Revenue Model

In terms of revenue model, industrial and commercial storage and large storage have their own characteristics. The revenue of industrial and commercial storage mainly comes from electricity bill savings, demand response revenue, renewable energy subsidies, etc., and focuses more on reducing the operating costs of enterprises and improving energy efficiency. The revenue of large storage may come from power market transactions, power auxiliary service fees, cross-regional power dispatching, etc., and focuses more on obtaining revenue in the energy market.

Risks and Challenges

There are also differences in risks and challenges between industrial and commercial energy storage and large energy storage. The risks faced by industrial and commercial energy storage may include technology updates, market competition, policy changes, etc., and enterprises need to choose appropriate energy storage technologies and business models based on their own conditions. The challenges faced by large energy storage may include large-scale system integration, grid security, market access, etc., which require comprehensive consideration of policies, technologies, markets, and other aspects.

Future Outlook

As the global energy transformation continues to deepen, both commercial and large-scale energy storage will have a broader space for development. Technological progress, market development, policy support and cross-border cooperation will bring more opportunities for these two energy storage systems. At the same time, it also requires all parties to work together to promote the healthy development of the energy storage industry and contribute to the realization of a green, low-carbon and sustainable energy future.

Conclusion

By comparing and analyzing the differences between industrial and commercial storage and large storage, we can find that although the two are different in scale, application scenarios, technical routes, business models, etc., they both have important value and potential. They can provide support for energy transformation and sustainable development. Therefore, both industrial and commercial storage and large storage are worthy of our attention and research, in order to play a greater role in the future energy system.
