How did we do it?What worked for us may not work for others Options depend on the state regulations and the local utility The process evolved as we went through it.
How did we do it?We first approached AEP Ohio, the local utility.Due to regulatory constraints, without special approval from the PUCO all they could offer was renewable energy certificates or a buy/sell arrangement from Ohio wind farms.Ohio is deregulated and Certified Retail Electric Service (CRES) providers were becoming more competitive with the regulated utilities. However . . .AEP Ohio was in the middle of a major rate case which would have a significant impact on the cost of power supplied by a CRES provider. Resolution of the rate case which was settled then reversed then finally settled after 20 months delayed final agreement and implementation.We solicited proposals from a few CRES providers to supply our main substation load with a significant portion of the electricity supplied from an Ohio wind farm.AEP Energy, formerly known as AEP Retail, the unregulated arm of AEP, proposed providing our electricity load including 50 MW of capacity from the Blue Creek Wind Farm, a subsidiary of Iberdrola SA, located in Van Wert and Paulding Counties. This was an existing wind farm with uncommitted capacity. The 50 MW of capacity was projected to provide 25% of our electric load.The AEP Energy proposal included what we felt was a signification mark up and risk avoidance cost so working with AEP Energy we negotiated a direct power purchase agreement with Blue Creek Wind Farm and an agreement with AEP Energy to tunnel the wind power to OSU with a direct pass through of the associated costs and provide the remaining electric power load at a fixed cost.

Project Capacity304 Megawatts (MW)
Number of Wind Turbines152 Gamesa G90, 2.0 MW wind turbines on 100m (328 ft) towers, which are primarily made in Pennsylvania.
TechnologyTurbines on a 328 foot (100 meter) tower for a total height of 476 feet when a 148 ft long blade is straight up. Each nacelle weighs 85 tons. Each foundation uses about 60 truckloads of concrete and 60 tons of steel rebar.
