Arevon Advances 250MW Cormorant Storage Project in California
Event summary
- Arevon's 250MW/1,000MWh Cormorant energy storage project in Daly City, California, marked significant construction progress on September 16, 2026.
- The project, using lithium iron phosphate battery technology, is expected to begin operations in 2027 and will power 321,000 homes for up to four hours during peak demand.
- Cormorant is under a long-term offtake agreement with MCE and was expanded from its original 188MW/752MWh plan.
- The project will generate over $73 million in property tax revenue and avoid 174,000 metric tons of CO₂ annually.
The big picture
Arevon's Cormorant project underscores the growing importance of energy storage in California's transition to a cleaner grid. With over 20 gigawatts of new clean resources expected by 2032, battery storage is critical for balancing solar generation declines and peak demand periods. Arevon's expansion of the project from 188MW to 250MW highlights the increasing scale of storage investments in the state.
