Ohio Power Siting Board approves Oak Run Solar project permit

On September 18, 2026, the Ohio Power Siting Board granted approval for the Oak Run Solar project, marking a significant step for renewable energy in Ohio. Located in Madison County, this project will be the largest solar and battery facility in the state, featuring 800 megawatts (MW) of solar power combined with 300 MW of battery storage. Additionally, it will incorporate agrivoltaics, allowing around 1,000 sheep to graze among the solar panels. This innovative approach promotes clean energy while supporting agricultural practices, showcasing a model for sustainable development.

Historically, Ohio has faced numerous challenges in advancing renewable energy projects, particularly solar and wind initiatives. Over the past twelve years, the Ohio legislature has enacted stricter regulations, including increased setbacks for wind turbines and reduced clean energy standards, creating significant barriers for renewable developers. The Power Siting Board has increasingly relied on local government opposition to deny permits for solar projects, complicating the landscape for clean energy development. Despite these challenges, the approval of the Oak Run project represents a rare victory for clean energy advocates in a state known for its resistance to renewable projects.

The Oak Run Solar project, developed by Savion, initially sought a permit in 2022. After a lengthy legal process, including appeals from the Madison County government and several townships, the project faced a prolonged hold on its progress. A recent court ruling prompted the Power Siting Board to reevaluate the project, specifically regarding the visual impact of substations. Savion submitted additional evidence, including renderings and testimony, which ultimately convinced the board to approve the permit by a vote of 7 to 2. Despite ongoing objections from local governments, the board concluded that the project met the necessary criteria for approval.

The approval of the Oak Run Solar project is expected to bring significant economic, environmental, and social benefits to the region. By integrating solar energy with battery storage, the project aims to enhance the reliability and affordability of electricity in Ohio. Renewable energy sources like solar are increasingly recognized as the most cost-effective means of generating electricity, with more than 90% of new power generation in the U.S. coming from wind, solar, or battery sources in recent years. Clean energy advocates believe that projects like Oak Run will play a crucial role in meeting the growing energy demands in Ohio while promoting a sustainable future.

Looking ahead, the Oak Run Solar project represents a pivotal moment for renewable energy in Ohio, potentially setting a precedent for future developments. With the permit now granted, Savion can move forward with construction, subject to any further legal challenges from local governments. The project underscores the importance of renewable energy in Ohio's energy portfolio and highlights the ongoing struggle for clean energy development in a state with a complicated regulatory landscape. As advocates await further rulings from the Ohio Supreme Court regarding other solar projects, the success of Oak Run could inspire similar initiatives and foster a more favorable environment for renewable energy in the future.
