California sees sustained decline in natural gas use as solar output rises
California’s electricity mix is shifting as utility-scale solar generation nearly doubles its 2020 output and battery storage increasingly displaces natural gas during evening peaks, according to new data from the US Energy Information Administration (EIA).
LevelTen warns of rising PPA prices amid US trade, policy strain
Power purchase agreement (PPA) prices for solar projects in North America rose 4% in the third quarter of 2025, with LevelTen Energy warning that tariffs and policy uncertainty could push costs even higher.

Design solar for storage now, or retrofit at a premium later
New analysis of retrofitting solar power plants with energy storage, accounting for the industry’s rapidly falling prices, suggests that prepping your solar projects today has a strong chance of being in your financial interest.
Gaining a battery storage edge in California and Texas grids
A GridBeyond study says succeeding in saturated battery storage markets requires software-driven agility and real-time decision-making.
Solar power curtailment rises in California
Curtailment – the intentional reduction of power production – continues to rise for both solar and wind power in California.
Batteries set new output record in California
Amid industry turmoil, California has been setting new benchmarks for the volume of instantaneous electricity injected into the grid by the state’s battery and solar sites.
Regulations, solar resources shaping growth of US energy storage
A new report from GridBeyond examines how regulations and solar resources drive prices in the United States.
California crosses 10 GW battery storage threshold
California is adding massive amounts of battery energy storage and the project pipeline shows no sign of slowing down. Batteries are playing an increasingly dominant role on the grid, soaking up solar in the middle of the day and shifting it to the evening peak, where they have become the biggest single supplier.
