Duke Energy
Duke Energy is a Fortune 150 US electric utility, headquartered in Charlotte, North Carolina, whose water-investment footprint is a single strategic bet: SOURCE Global, the solar-hydropanel maker that pulls drinking water from air. As of 2026, Leviathan tracks Duke Energy backing 1 water company across 2 rounds, a One-Off for a utility that itself began as a 1904 hydroelectric pioneer.

The take
Duke Energy is a power company, not a water investor, and yet it turns up in a water database for a reason older than almost any fund I track: it was born on a river. The company dates to 1904 and the Catawba Hydro Station in South Carolina, where James Buchanan Duke and engineer William States Lee turned falling water into electricity for the Carolina textile mills. Water was Duke Energy's first fuel.
Duke Energy's water-investment record, as I have it, is exactly one company. Through its solar program it backed SOURCE Global, the Arizona maker of solar Hydropanels that draw pure water vapor out of the air and condense it into drinking water, with no grid and no pipes required. Duke joined across two rounds alongside Bill Gates' Breakthrough Energy Ventures, BlackRock and Microsoft's Climate Innovation Fund. For a utility the logic is tidy: it already runs solar at scale, and SOURCE turns that same sunlight into water.
That makes Duke Energy a One-Off in water, a strategic cheque rather than a thesis, and the page says so plainly. It is a Fortune 150 utility serving 8.4 million electric customers across six states, with water threaded through its core business as cooling and hydropower. If you are watching for a corporate that already understands water-from-air at utility scale, Duke Energy is the one name on this list that has written the cheque.

Frequently asked
- What does Duke Energy invest in?
- Duke Energy is an electric and gas utility, so most of its capital flows into grids, generation and clean-energy infrastructure. In water technology specifically, Leviathan records a single venture investment: SOURCE Global, a maker of solar-powered Hydropanels that produce drinking water from air.
- Does Duke Energy have a corporate venture capital arm?
- Duke Energy does not run a dedicated water-focused venture fund. Its water-technology exposure comes from strategic and solar-program investing rather than a standing VC team. Its one tracked water bet, SOURCE Global, was backed through Duke Energy's solar program alongside Breakthrough Energy Ventures and BlackRock.
- What is SOURCE Global and why did Duke Energy back it?
- SOURCE Global, based in Arizona, builds Hydropanels that use sunlight to pull water vapor from air and turn it into drinking water, off-grid and pipe-free. Duke Energy, already a large solar operator, joined its funding alongside Bill Gates' Breakthrough Energy Ventures and Microsoft's Climate Innovation Fund.
- Where is Duke Energy based?
- Duke Energy is headquartered in Charlotte, North Carolina, and is one of America's largest energy holding companies: a Fortune 150 utility serving 8.4 million electric customers across North Carolina, South Carolina, Florida, Indiana, Ohio and Kentucky. It traces back to a 1904 hydroelectric station on the Catawba River.
- Is Duke Energy connected to Duke University or Duke Capital Partners?
- Duke Energy, the Charlotte-based utility, is a separate company from Duke University and from Duke Capital Partners, the university's investment group. They share the Duke name through philanthropist James Buchanan Duke, who both founded the utility and endowed the university, but Duke Energy's water investing is its own corporate activity.
