U.S. Energy Information Administration Report: Top 10 States for Solar and Energy Storage Market in 2026 - Ranking and Forecast Data

 

 

 

The latest data from the U.S. Energy Information Administration shows that California leads the nation in solar power generation share with 32.1%, followed by Nevada at 25.4% and Hawaii at 21.2%. In terms of cumulative installed solar capacity, California leads with approximately 55,000 MW, followed by Texas at approximately 51,900 MW and Florida at 20,100 MW.

As the battery revolution continues to reshape the future of energy storage, the application of battery energy storage system has become essential for stabilizing the grid and maximizing the value of renewable energy. In particular, battery storage for solar energy system is now widely adopted to store excess daytime solar production for evening and nighttime use.

Based on the three-year installation forecast from 2026 to 2028, Texas has approximately 38,000 MW of utility-scale photovoltaic power plant projects in the pipeline, ranking first. In the relative capacity growth forecast for 2025-2026, Kentucky leads with a 251.6% increase.

The installed capacity of utility-scale battery storage in the United States has exceeded 40 gigawatts, with California leading the way with approximately 18.5 gigawatts of operational capacity, followed by Texas with approximately 12.2 gigawatts and Arizona with approximately 3.1 gigawatts. For homeowners and small businesses seeking flexible solutions, options like a 7 kWh battery energy storage system for rent are also gaining popularity as an affordable way to get started with home energy storage.

This report primarily covers facilities with a rated capacity of 1 megawatt and above. Storage rankings are based on power capacity, and installation forecasts are based on developer reporting timelines and may be adjusted due to supply chain, permitting, or grid connection delays. BLOO POWER offers reliable and innovative energy storage solutions to support both large-scale and residential needs in this rapidly evolving market.
