Cincinnati Launches 18.2‑MWh/Year Solar Array on Former Landfill to Power 1,700 Homes

Cincinnati initiated construction of a significant solar array on a former landfill, aiming to generate 18.2 million kilowatt-hours annually to power 1,700 homes.

Cincinnati began transforming a former landfill into a renewable energy hub on Friday. City officials broke ground on the Center Hill Solar Array, located at the site of the former Center Hill Landfill. This project represents one of the city’s largest renewable energy investments, converting a long-vacant brownfield—a former industrial or commercial site with potential environmental contamination—into an active clean energy asset.

The Center Hill Solar Array is projected to produce 18.2 million kilowatt-hours of electricity each year. This substantial annual output is sufficient to supply approximately 1,700 homes with clean energy. The array’s operation will also contribute directly to reduced greenhouse gas emissions by displacing electricity generation from fossil fuels, marking tangible progress in the city's environmental efforts.

Construction of the array is set to begin this year. The project is expected to become operational, commencing electricity generation and supply, next year.

This initiative aligns with Cincinnati's broader environmental strategies, specifically the Green Cincinnati Plan. This plan outlines comprehensive objectives for sustainable development, including significant transitions in the city's energy production and a reduction in its carbon footprint. The repurposing of the former landfill site for clean energy production demonstrates a practical approach to urban land use, transforming a non-productive area into a source of renewable power.

Developing solar arrays on brownfield sites offers a dual benefit: it reclaims land often unsuitable for residential or commercial development and contributes to local clean energy generation. This approach avoids using undeveloped greenfield land for energy infrastructure while addressing environmental liabilities associated with former industrial areas. The Center Hill project positions Cincinnati as an active participant in the national transition towards a more sustainable energy grid.

The successful implementation of projects like the Center Hill Solar Array is crucial for urban centers aiming to meet emissions reduction targets. The deployment of solar technology on a significant scale, even on challenging sites, illustrates a commitment to renewable energy infrastructure development.

Observers will monitor the array’s operational launch next year and its subsequent impact on Cincinnati’s energy independence and emissions targets, tracking its measurable contribution to the city's renewable energy goals and broader climate objectives.
