Less than a decade ago, South Korean companies held over half of the global energy storage system (ESS) market with the rushed promise of helping secure a more sustainable energy future. However, a string of ESS-related fires and a lack of infrastructure had dampened investments in this market.
The Gyeongsan Substation – Battery Energy Storage System is a 48,000kW lithium-ion battery energy storage project located in Jillyang-eup, North Gyeongsang, South Korea. The rated storage capacity of the project is 12,000kWh. The electro-chemical battery storage project uses lithium-ion battery storage technology.
The Nongong Substation Energy Storage System is a 36,000kW lithium-ion battery energy storage project located in Dalsung, Daegu, South Korea. The rated storage capacity of the project is 9,000kWh. The electro-chemical battery storage project uses lithium-ion battery storage technology.
Fuelled by rapidly increasing demand within China itself, Chinese batteries account for nearly 90 per cent of global capacity for energy storage systems (ESS), including a market share of more than 80 per cent in the US and more than 75 per cent in Europe.
Since the majority of solar projects currently under construction include a storage system, lenders in the project finance markets are willing to finance the construction and cashflows of an energy storage project. However, there are certain additional considerations in structuring a project finance transaction for an energy storage project.
Read more about the different solar financing options available. In 2025, solar.com Energy Advisors typically recommend using a solar loan to finance a solar system — if the homeowner can efficiently monetize the 30% federal tax credit. If they can't, then a solar lease or PPA is the best option.
The rapid growth in the energy storage market is similarly driving demand for project financing. The general principles of project finance that apply to the financing of solar and wind projects also apply to energy storage projects.

The 2025 Solar Builder Energy Storage System Buyer's Guide is here to cut through the noise. This ESS Buyer's Guide is a comprehensive list of what each brand is offering in the residential and C&I space heading into 2025. We sent a questionnaire to every manufacturer to ascertain their top product and what components are included.
The system consists of: Ready to install liquid-cooled battery energy storage system with one (2-hour version) or two (4-hour version) battery cabinets, and a PCS cabinet. Liquid cooling provides two years longer battery service life and 15% higher discharge capacity, while maintaining less than 2.5 degree C delta between cells.
By sourcing batteries separately, users can expand their energy storage capacity as needed without overhauling the entire system. This scalability makes it an ideal solution for both residential and light commercial applications, future-proofing investment and enabling smart energy management.
ESS is listed. See ESS specs above. System components: GM Energy PowerBank is a stationary energy storage system available for purchase in 10.6kWh and 17.7kWh battery capacity variants. The 17.7kWh GM Energy PowerBank can be combined to create a 35.4kWh stationary storage solution.
