About the Project
Cherokee Industrial Resilient Power is a proposed 250 MW AC (1,000 MWh) standalone battery energy storage project on an estimated 25-acre developed footprint, in Tulsa County, Oklahoma.
The facility is expected to include battery storage containers inside a secure, fenced site designed to meet all applicable industrial safety and fire codes.
We expect to begin construction around Q4 2029 and reach commercial operation by Q4 2030, subject to permitting and interconnection timelines.
Frequently Asked Questions
A proposed 250 MW / 1,000 MWh battery energy storage project in Tulsa County, Oklahoma, designed to safely provide affordable electricity and a more resilient grid. Developed by Sofos Power.
A: Approximately $900,000 in annual tax revenue, 30 to 50 construction jobs at peak, 2 to 4 permanent positions, and an estimated $11 million or more for Owasso Public Schools over 20 years.
A: The system draws electricity from the grid when it's available, stores it, and then discharges that power back to the grid later, typically during periods of high demand.
A: Like most utility-scale battery storage systems built today, Cherokee Industrial Resilient Power is expected to use lithium-ion battery technology, the same technology used in most battery electronics today. The batteries are third-generation NFPA and UL compliant Lithium Iron Phosphate (LFP) battery enclosures.
40,000+MW across 1000+ BESS facilities are safely operating in the US with even more operating across the globe. Battery storage is an established, increasingly common technology across the U.S. The project will be designed, permitted, and operated to meet all applicable fire and life-safety codes, including code-required spacing, detection, and suppression systems.
A: The facility will include safety systems designed to detect and contain incidents on-site, and will go through fire-safety and environmental review as part of permitting. Each and every piece of equipment on site is monitored remotely 24/7, with automatic shutoffs built in to handle any malfunctions before they become larger issues.
Fire safety and environmental protection are central to the project's design and will go through environmental and fire-safety review as part of permitting.
A: No. Unlike a power plant, a battery storage system doesn't burn fuel or generate emissions on-site. It stores and releases electricity that's already part of the grid.
A: Battery storage facilities utilize cooling equipment that produces noise on site. Cooling equipment only runs when necessary, and engineered noise studies are forecasting that the system will be low-noise to inaudible from surrounding properties.
A: Systems like this one are typically designed to operate for the life of the project, approximately 15 to 20 years.
A: At the end of its operating life, equipment will be removed in accordance with applicable state and local regulations. The site will be returned to it original state in accordance with Oklahoma state law and nationwide requirements set by NFPA 855, the project will be decommissioned safely and the site will be returned to its original state
A: The system draws power from the existing electric grid. It's a standalone storage project, not paired with on-site generation.
