Hydrostor, Canada’s main developer of long-duration vitality storage initiatives, is transferring forward with its $1.5 billion Willow Rock Power Storage Heart in Kern County, California. The venture makes use of compressed air to retailer renewable vitality and can ship 500 MW of energy for as much as eight hours. It’s virtually 2X that of most lithium-ion battery methods can maintain. If accomplished, it might mark the primary compressed air vitality storage (CAES) facility constructed within the U.S. in additional than 30 years.
S&P World not too long ago offered an replace concerning its allow processes for the Willow Rock Power venture.

As per EIACalifornia’s renewable electrical energy web summer season capability reached 41,733 megawatts by December 2024, accounting for 11.3% of all the U.S. whole. In the identical interval, 12.8% of all vitality consumed in California got here from renewable sources.
Large Wins for the Energy Grid
- Extra dependable electrical energy: Willow Rock will ship out energy when photo voltaic and wind aren’t sufficient.
- Higher use of energy traces: It can retailer vitality when there’s an excessive amount of and ship it out when wanted, serving to the entire grid run smoother.
- Provides tech selection: In contrast to batteries, A-CAES brings a special type of storage — one which lasts longer and stays robust over time.
- Eco-friendly selection: The system doesn’t burn something, makes use of little or no land and water, and produces virtually no waste.
By changing previous fossil-fuel backup crops, Willow Rock will assist California hit its local weather objectives. It helps the state’s goal to chop emissions 40% under 1990 ranges by 2030 and to succeed in 100% renewable energy by 2045.
