Frontier Power USA acquires late-stage utility-scale battery storage projects and converts them into construction-ready assets, then finances, builds and operates those assets. The company acquired the 200 MW / 800 MWh Blanquilla project, which will use Eos Z3 long-duration battery systems, and placed a roughly $100 million purchase order with Eos for Phase 1. Financing for projects such as Blanquilla is expected to combine Frontier Power USA equity and debt arranged through KKR Capital Markets, and projects will be covered by a Technology Performance Insurance framework arranged with Ariel Green. Stella Energy Solutions is providing development and engineering services for converted projects and has prior experience developing over 4.4 GWh of utility-scale storage. As of the transaction Frontier Power USA has converted 1,280 MWh of usable capacity, is advancing about 5 GWh of acquired/selected/under-diligence projects, and identifies a pipeline of roughly 16 GWh. The company positions this raise and initial purchase order as supporting a repeatable model for acquiring, financing, building and operating battery storage assets.
