About
One Energy America LLC is the United States arm of the One Energy Group, with operations in the United States, Canada and Brazil. We engineer, build and maintain battery storage and solar — and we supply the crews when someone else holds the contract.
Who we are
One Energy America LLC is headquartered at One World Trade Center in New York and works across the mainland United States and Puerto Rico. We are a registered contractor in Delaware and New York, a member of the National Electrical Contractors Association, and a Tesla Energy partner for storage integration.
We are part of the One Energy Group, alongside One Energy Brasil and One Energy Canada. Across the group, our companies have delivered 450+ MW of solar and integrated 175+ MW of battery energy storage. The engineering standards are shared; the market approach is local.
What we are not: a residential rooftop installer, a module reseller, or a developer competing with our own clients for projects.
How we work
We ask for geotechnical data, interconnection status and equipment delivery dates before committing to a schedule. A date given without them is a guess.
If you hand us your pipeline to staff, we will not appear as your competitor on the next round.
We give generation profiles, sized systems and honest limits. Payback depends on your tariffs and your operations, and anyone promising a number is guessing.
Talk to engineering
Every contractor has one. We will tell you about ours, what it cost and what we changed afterwards. That conversation is more useful than a capability deck.
