The U.S. Energy Information Administration (EIA) has recently released a report projecting a significant increase in battery energy storage capacity in the United States in 2024. According to the report, the country is set to achieve a new record in battery energy storage capacity, with a prediction that by the end of 2024, the capacity will nearly double. This growth would account for 23% of new power generation capacity in the United States, positioning battery energy storage as the second-largest source of new power generation capacity, trailing only behind solar energy. Existing battery energy storage capacity in the U.S. stood at 15.5GW as of the end of 2023, and with planned developments, this capacity is expected to increase by 14.3GW in 2024, reaching a total of over 30GW.

The scale of growth in battery energy storage is set to surpass the generation capacity of other sources such as petroleum liquids, geothermal, wood and wood waste, or landfill gas. The EIA data highlights that California and Texas are the primary regions for battery energy storage installations, with 7.3GW and 3.2GW of battery energy storage capacity, respectively. The report anticipates that Texas and California will contribute 6.4GW and 5.2GW of new battery energy storage capacity, accounting for 82% of the total new capacity in the U.S in 2024. The demand for battery energy storage continues to rise alongside the increasing installation of solar and wind energy capacity in the country. The rapid expansion of solar and wind capacity in states like California and Texas is supporting the growth of battery storage infrastructure.

The increasing integration of renewable energy sources into the grid is underscoring the essential role of energy storage in enhancing grid reliability. The heightened focus on grid reliability is a result of the growing importance of energy storage alongside the rise in renewable energy generation. It is important to note that the development of battery energy storage in the U.S. has received a significant boost from the Inflation Reduction Act. This legislation has expanded the eligibility for federal tax credits to stand-alone battery storage systems, previously limited to only those paired with photovoltaic installations. Furthermore, the declining prices of battery energy storage systems have further enhanced the economic viability of these projects.

Despite the positive projections for battery energy storage capacity in the U.S., challenges related to supply chain issues and grid connection delays persist. An example of this was noted in December 2023 by the Electric Reliability Council of Texas, where delays in delivery times for large-scale battery storage projects were attributed to supply chain issues. The extended project timelines are expected to take 12 to 18 months for completion, approximately six months longer than originally planned. Developer plans indicate that over 300 large-scale battery energy storage projects are anticipated to be operational in the U.S. by 2025, with around 50% of the planned capacity earmarked for installation in Texas.

Looking ahead, several large-scale battery energy storage projects are in the pipeline for deployment in California and Texas in 2024 and 2025. Some of the notable projects include the Lunis Creek BESS SLF in Texas with a capacity of 621MW, Clear Fork Creek BESS SLF in Texas with 600MW, and Hecate Energy Ramsey Storage in Texas with 500MW. In California, projects like the Bellefield Solar and Energy Storage Farm with 500MW, Menifee Power Bank with 460MW, and Dogwood Creek Solar and BESS in Texas with 443MW are also set to contribute to the growing battery energy storage capacity in the country. These projects signify the ongoing momentum towards further expansion and development of battery energy storage infrastructure in the U.S.
