Both houses of the state's General Assembly passed a reconciled version of Senate Bill 232, which creates an exemption from tangible personal property taxes for renewable energy projects begun between 2009 and 2012.
The bill now passes to governor Ted Strickland for his signature or veto. His approval seems a given, as the American Wind Energy Association (AWEA) said Strickland had worked to advance the legislation.
Republican state senator Chris Widener sponsored the bill, which was cosponsored by four Republicans and seven Democrats.
AWEA chief executive Denise Bode said: "This tax reform will encourage wind energy investment in Ohio, and it will create and protect thousands of manufacturing, construction, operations and maintenance jobs in the state.
"Ohio is now much better positioned to attract wind power investment that will benefit local communities and boost orders for turbines and turbine components."
Recently, Oklahoma considered axing tax credits for the wind industry. The Senate Bill 1267, which calls for the scrapping of a number of tax credits, had been approved by the Senate. However, the wind energy credit was restored by the state's governor Brad Henry.
