The city of lima, ohio is constructing a floating photovoltaic (FPV) facility on the surface of twin lake reservoir, adjacent to the city's water treatment plant

The City of Lima received a $4.53 million Project Grant from the U.S. Department of Energy's Office of Energy Efficiency and Renewable Energy under the Renewable Energy Research and Development program (CFDA 81.087), awarded August 1, 2025, with completion targeted for January 31, 2027. The grant funds construction of a 2-megawatt (MW) floating photovoltaic (FPV) facility on Twin Lake Reservoir adjacent to the city's water treatment plant in Lima, Ohio. The FPV system comprises over 3,500 photovoltaic panels spanning approximately 4 acres of water surface and will directly supply renewable energy to the municipal water treatment plant, reducing the facility's reliance on grid-supplied electricity.

This project represents a demonstration of floating photovoltaic technology deployment at the municipal level and aligns with the Renewable Energy Research and Development program's objective to support development, demonstration, and deployment of clean energy technologies that improve performance and lower costs. By integrating solar generation capacity at an existing water infrastructure site, the City of Lima is advancing renewable energy adoption while simultaneously reducing operational costs for essential public water services.

The FPV system will have a power output of 2MW, consisting of over 3,500 PV panels spanning more than 4 acres of water surface. The power generated by this system will directly supply the city's water treatment plant.
