The U.S. Environmental Protection Agency (EPA)’s Clean Power Plan, expected to be released this summer, should be a factor in Ohio’s future green energy law, said state utility and environmental regulators to the Energy Mandates Study Committee earlier this month, Gongwer reports. Ohio EPA Director Craig Butler and Public Utilities Commission of Ohio (PUCO) Vice Chairman Asim Haque said the federal government’s pending carbon dioxide emissions limits “would prove costly to Ohio utility customers.” Butler and Haque, however, “said it’s unclear whether Ohio’s renewable and energy efficiency standards would help or hinder the state” in complying with those limits. The new federal carbon rules “might drive development of the renewable energy credit market and technological improvements that would reduce ultimately compliance costs,” Haque said, but “reducing the amount of renewables and energy efficiency in Ohio’s overall electricity mix will likely increase costs.” Butler said the U.S. EPA draft rules issued last year (for more on this, see our June 5, 2014 blog post) do not have enough detail to determine whether Ohio’s renewable energy and energy efficiency standards “are sufficient to meet the U.S. EPA’s carbon reduction targets.” Butler said the Ohio EPA will seek an extension to “give the state until early 2018 to devise a compliance plan.”
