Summary

Story summary

D3Energy and ARP Solar completed a 2-megawatt floating solar array on Twin Lake Reservoir in Lima, Ohio.
The array occupies four acres, saving six acres compared with a comparable ground-mounted farm.
Installation used over 3,100 bifacial panels on floating platforms.
Funding came from a $2.4 million DOE grant and about $1 million in tax credits.
The plant will save roughly $10 million in electricity costs while powering a water-treatment facility serving 35,000 residents.

History

Historical Context

Japan announced a pilot floating wind farm off Fukushima in 2011, a step that coincided with the 78 MW Shin Izumo wind farm becoming the country’s largest. Building on that experience, D3Energy and ARP Solar installed a 2-MW floating solar array on Ohio’s Twin Lake Reservoir in 2024 with a $2.4 million DOE grant, showing floating photovoltaics cut land use.
