As of 2022, there are a total of 39 states with utility-scale BESS in the United States. Among them, California, Texas and Florida have the largest installed capacity, accounting for more than 80%.
✓ Regional power grids in the United States are independent of each other, and energy storage assists large-scale cross-regional dispatch
The U.S. energy storage market has obvious regional differentiation, mainly concentrated in California and Texas. As of 2021, California’s energy storage installed capacity is 2339.1MW, accounting for 44%; Texas’s energy storage installed capacity is 797.4MW, accounting for 15%. The rapid development of California and Texas is mainly related to factors such as unstable power infrastructure and obvious policy incentives.
U.S. energy storage is currently mainly composed of three major power grid groups: Eastern United Power Grid, Western United Power Grid and Texas Power Grid. The three major power grids are relatively independent. Since UHV technology has not been widely used in the United States, and the distance is too long and the losses are too great, power grid groups are unwilling to carry out interstate transmission. Therefore, they operate independently, making it difficult to carry out large-scale cross-regional dispatch. Therefore, power auxiliary services are needed to help complete consumption, and the installed capacity of energy storage on the power generation side and the grid side has increased significantly.
✓ The installed capacity of the energy storage market is expected to reach 28.3GWh in 2023
At present, the United States has taken a number of measures to clear the backlog of grid-connected projects, which are expected to be implemented in the next 2-3 years. The energy storage market is expected to increase to 44.2GWh and 68.2GWh in 2024-2025, with a CAGR of 59.5% from 2021-2025.

Energy storage trends in EU storage markets in recent years
On July 19, 2023, the European Parliament passed the power reform plan to encourage the power grid to introduce more non-fossil fuel flexible resources (such as energy storage, demand side response), and improve investment returns through capacity markets and other methods.
In 2020, the 50MW capacity limit for a single battery energy storage project will be officially removed, significantly shortening the approval cycle for large storage, and at the same time canceling the dual charging mechanism for energy storage on the generation/consumption side. DR and DM services were launched in 2022.
Regulators approve new grid-scale energy storage auction rules. Terna said around 94GWh of energy storage will be needed to integrate planned renewable energy in Italy. Research firm LCP Delta predicts that 800-900MW of energy storage will be deployed in 2023-2024, second only to the UK in scale.
The government plans to fund 160 million euros to deploy 600MW energy storage projects that will be connected to the grid in 2026. State aid of 280 million euros will be launched in July 2023 to support independent energy storage projects and pumped storage hydropower projects.
In 2020, the “innovative bidding” was launched for the first time to assist the implementation of energy storage and other renewable energy projects. At present, Germany’s large storage units are small in scale, with about 77% of large storage projects having a capacity of less than 10MWh.
A large-scale battery storage auction has been approved by Greek regulators. The independent energy storage procurement process will start in Q3 2023, and the system will be completed by the end of 2025.
✓ Europe | Future Outlook: Installed capacity will reach 11.3GWh in 2023, CAGR will reach 53% from 2021 to 2025
After Russia restricted gas supplies in 2021, Europe began switching from gas to coal. At present, electricity prices in many European countries are still higher than before the Russia-Ukraine conflict, and the fundamentals of electricity have not improved. Europe, as a mature market for household savings, will remain hot. In addition, the power supply levels of European hydropower vary greatly between dry and wet periods, and the dependence on wind and solar power generation is gradually increasing.
The large-scale storage market will have an installed capacity of 2GW in 2022, which has begun to take shape; in July 2023, after the European power reform plan is passed, the large-scale storage market will have the momentum to start volume. From 2023 to 2025, the newly installed energy storage capacity will reach 11.3GWh, 18.3GWh, and 26.4GWh.
