On site & on the floor

The team behind every energization.

Founded by a technician

One of the only firms built solely for BESS.

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.
