Ohio’s latest power struggle is not just happening on the grid, it is unfolding in the Statehouse, where lawmakers are pushing a new legal definition of "reliable" energy that critics say could sideline a big chunk of utility-scale solar and wind projects.
The proposal would force projects to prove they run at least half the time and can be turned up or down on short notice, a standard that fits gas and nuclear far more neatly than it does standalone renewables. Supporters frame it as a commonsense reliability check. Opponents see a stacked deck that favors fossil fuels over clean energy.
Senate Passage And Local Reporting
On June 10, the Republican-controlled Ohio Senate voted along party lines to pass Senate Bill 294, a measure its backers say will put "affordable, reliable, and clean" power at the center of state siting decisions. Observers have linked the bill’s structure to a model from ALEC, a conservative policy shop. The bill cleared the Senate and headed to the Ohio House for the next round of debate, according to Columbus Underground.
What The Bill Actually Requires
SB 294 would write a new definition of "reliable energy source" into state law. To qualify, a resource would have to be "readily available at all times" and, when used for power generation, hit "a minimum capacity factor of fifty per cent" while also being able to ramp output up or down within one hour.
The bill language tells state siting officials to give priority to domestically produced energy and allows certain hydrocarbon and nuclear plants to be treated as "clean" under Ohio law. Those criteria would apply when the Ohio Power Siting Board weighs applications for major utility facilities, according to the bill text on the legislature’s site. Ohio Legislature.
Why Analysts Say The Metric Is A Poor Fit
Capacity factor tracks how much electricity a plant actually produces over time compared with what it could generate if it ran at full tilt around the clock. That means resources that only run when the sun is up, or the wind is blowing naturally, show lower capacity factors, even if their output is predictable and valuable to the grid.
Federal data show that U.S. utility-scale photovoltaic solar clocked an average capacity factor of 24.4% last year, which is less than half of SB 294’s proposed 50% threshold. "Capacity factors are not measures of reliability and the wrong thing to focus on," Andrew Linhares of the Solar Energy Industries Association warned in comments reported during the debate, according to EIA and Canary Media.
Supporters, Opponents And The Vote
Supporters of SB 294 say it gives regulators sharper tools to decide if a project really serves the public interest. They argue that with more weather-dependent resources coming online, Ohio needs firmer rules around what counts as reliable power.
Opponents counter that the bill would channel investment toward fossil fuel and nuclear projects while making it tougher and more expensive for solar and wind paired with storage to compete. At Senate hearings, groups focused on domestic fuel and infrastructure priorities testified in favor, while the Ohio Chamber of Commerce, renewable energy trade associations and environmental organizations lined up against the original version.
Legislative records name Sen. George Lang as the lead sponsor and show the bill passing the chamber on a 24-9 vote before it moved to the House. The summary and roll calls are posted on the tracking site LegiScan, with additional coverage from Columbus Underground.
Legal Implications For Siting
If SB 294 becomes law, its definition of reliability would be baked into the legal framework that guides how the Ohio Power Siting Board reviews certificate applications for major utility facilities. Under existing rules, that generally means power plants of 50 megawatts or more, with some special treatment for certain wind additions.
The change would shape how the board weighs tradeoffs among reliability, cost and environmental impacts when it rules on big-ticket projects. For more on the OPSB’s scope and definitions, see Ohio administrative rule 4906-1-01 in the Ohio Administrative Code.
What Happens Next
SB 294 now sits in the Ohio House, where lawmakers returned to Columbus following the Senate vote and formally introduced the measure in mid-June. House committees are expected to take testimony as members juggle competing visions of reliability and the state’s clean energy future.
If the House signs off on the same language, the governor will have the final say, with the option to sign the bill, veto it, or let it become law without a signature. The latest status and roll calls are posted on LegiScan.
In the meantime, trade groups and local stakeholders are already drawing battle lines. Clean energy advocates argue Ohio’s fast-growing appetite for low-cost power will be best met by a portfolio that leans on solar plus storage. Backers of SB 294 insist that without a tougher reliability yardstick, the grid could be left vulnerable.
The next act will play out in House committee rooms rather than at press conferences, as lawmakers decide whether this reliability test becomes the rulebook for Ohio’s next generation of power plants.
