Duke Energy Ohio, a retail gas and electric service company serving approximately 650,000 electricity customers in Southwestern Ohio, filed an application with the Public Utilities Commission of Ohio to offer a green power tariff. Under the two-year pilot program, customers could choose to purchase power "from renewable energy and other environmentally friendly energy sources" in 100-kWh blocks at a rate of 2.5¢/kWh. The minimum monthly purchase commitment would be 200 kWh ($5 per month) and customers must agree to subscribe for an initial one-year period.
The company defines green power to include biomass co-firing, incremental improvements in large-scale hydro, and coal mine methane, in addition to wind, solar, biomass, and low-impact hydro. Duke Energy subsidiaries (formerly Cinergy/PSI Energy) also offer green power programs in Indiana and Kentucky.
