A look at projects we've taken from foundation to grid-compliant operation — and fleets we've brought back to earning.
Commissioning and long-term O&M on a 750 MWh standalone storage asset in Blythe, California — energized clean and kept earning.
availability recovered on a confidential Southern Texas site after GreEnergy took over O&M.
We mobilize multi-state, with self-performing field teams across 80+ self-performed projects and counting. Hover any pin for the site location.
We deliver for the owners and developers building out America's storage fleet — from utility-scale projects to the behind-the-meter systems powering the data-center boom — and they bring us back to the next project.
Representative counterparties · select engagements
Complex storage projects fail in the gaps — between scopes, between subs, between mechanical completion and a compliant asset. We're built to close them.
Written procedures, hold points, and documented sign-offs on every energization — backed by a safety record that beats the industry benchmark.
One prevailing-wage service provider, fully compliant and in-house across the critical path. No layered subs, no finger-pointing.
Senior people on site, proactive communication, and clean documentation your tax authority and the utility will actually accept.
"GreEnergy was the only team we trusted for site management and they proved why time and time again."
"GreEnergy provided exceptional installation, commissioning and back office support."
"Their deep expertise and professionalism, commitment to excellence was evident throughout each engagement."
The team behind every energization.
GreEnergy wasn't spun out of a general EPC chasing the storage boom. It was founded by a working BESS technician — so the people setting the schedule have terminated the gear, run the acceptance tests, and signed the energization sheet themselves. That's why the critical path stays in-house, and why owners keep calling us back.
