Ohio's Floating Solar Arrays Cut Costs, Power Communities

Fishers used to be the only visitors to Twin Lake Reservoir in Lima, Ohio, but now engineers are installing something remarkable: 3,400 solar panels floating on the water's surface.

The arrays will power Lima's water treatment plant, which runs electricity-hungry pumps 24/7 and represents one of the city's biggest energy expenses. By generating clean power on site, the project will help keep water rates stable for residents who've watched utility bills climb in recent years.

The floating solar approach solves a challenge that's been holding back clean energy in America's heartland. Agricultural land drives the midwest economy, and traditional solar farms compete with food production for precious acres.

"Floating solar resolves that equation," says Stetson Tchividjian, managing director of D3Energy, the Florida company behind Lima's project. The company has completed more than 25 floating solar installations across the U.S., including one three times larger than Lima's just 90 miles away.

The technology is surprisingly efficient. A floating system needs only two acres of water to generate one megawatt of power, compared to five acres for ground-mounted panels. When winter temperatures drop below freezing, water pumped from neighboring reservoirs prevents ice formation, keeping electricity flowing year-round.

Ohio might seem like an unlikely solar hotspot, but the state gets more sunshine than Oregon and nearly matches Alabama, according to the CDC. The midwest is quietly becoming a clean energy powerhouse. Illinois, Indiana, and Ohio now rank 10th, 11th, and 12th nationally for solar capacity.

An hour north in Perrysburg, First Solar operates one of the largest solar manufacturing facilities in the western hemisphere. The company recently opened a $2.4 billion research center developing next-generation solar technology that promises even higher efficiency.

The Ripple Effect

The floating solar boom is arriving at the perfect time for midwest communities. Global energy uncertainty has driven gas prices to $5 per gallon locally, while demand from data centers has pushed electricity rates higher.

Clean energy generated domestically isn't vulnerable to geopolitical disruptions thousands of miles away. For cities like Lima, that means more predictable costs and protection against price spikes that hurt residents and businesses alike.

The technology is creating opportunities beyond just energy savings. States like Michigan and Minnesota, with thousands of lakes, have enormous potential for floating solar installations that won't displace a single acre of farmland or natural habitat.

Lima's project demonstrates how innovation can turn overlooked spaces into community assets. What was once just a fishing spot now generates clean power that benefits every resident who turns on a tap.

The future looks bright, and in Ohio, it's also floating.
