US States ranked by installed battery capacity
If you follow the US power market closely you will know that California and Texas are far ahead of all other states in terms of installed battery capacity. California has 44.3% of the total US battery capacity followed by Texas at 28.6%. Arizona (8.0%), Nevada (4.3%) and Florida (2.1%) round out the top 5 states.
When analyzing the EIA’s January data, it was the 6th ranked state which was most interesting to me. How many would have placed Hawaii in the #6 spot, just behind Florida? Hawaii has 1.6% of the total US battery capacity. New Mexico, Colorado, Oregon, and Massachusetts round out the top ten and then all other states are less than 1% each. In fact, US states ranked 11 through 41 combined only account for 6% of total battery capacity and 9 states are currently reporting zero battery capacity as of January 2025.
I thought it would be interesting to analyze the battery capacity against each state’s population. Residential load is only one factor in electricity demand, but it is one relative comparison. I compared the latest population statistics and with that calculation, Hawaii ranks 2nd with only Nevada slightly ahead.
California and Texas are expected to aggressively expand their battery capacity and are projected to remain far ahead of all other states in the coming years.
As for Hawaii, the state shut down its last coal fired power plant in September of 2022. The state has invested in significant battery capacity, and continues to expand its solar generation capacity. This is all part of an aggressive goal to cease burning fossil fuels for electricity by 2045. In 2024, petroleum-derived fuels accounted for a significant portion of Hawaii’s electric generation. However, renewables grew considerably to 36% in 2024. That renewable generation included geothermal, biomass, hydro, wind, biofuels along with grid-scale solar and rooftop solar.
