First of Three New PSO Wind Farms Begins Commercial Operation

The sun sets at Sundance, PSO's newest wind farm located in Woods County.

There are more wind-generated electrons on PSO's grid than ever before thanks to Sundance - PSO's newest wind farm - that came online in April. Located in Woods County northwest of Aline, Sundance is the first of three new Oklahoma wind farms that will provide clean energy to PSO customers.

The 199-megawatt (MW) Sundance project is part of the 1,485-MW North Central wind project, from which PSO customers will receive 675 MW of power. North Central wind is a joint project with PSO's Shreveport, Louisiana-based sister company, Southwestern Electric Power Company (SWEPCO), which will receive 810 MW. Along with Sundance, it also includes the 287-MW Maverick and the 999-MW Traverse projects that are currently under construction. Maverick and Traverse are scheduled to be in service later this year and in early 2022, respectively. The facilities are being developed by Invenergy and will be purchased by PSO and SWEPCO at completion.

Taking advantage of one of Oklahoma's most abundant natural resources to power homes and businesses across the state is a win-win. Once all three of the new wind farms are in service, over a third of the projected energy needs for PSO's grid will come from wind, with much of that generated right here in the Sooner State.

"Before Sundance came online, wind generation made up 22 percent of our energy mix, and with the addition of the three new wind farms, that number will jump to about 34 percent," said Peggy Simmons, PSO president and chief operating officer. "Adding this new low-cost clean energy onto the electric grid will save customers money while continuing to provide affordable and reliable service Oklahomans need for today and the future."

Besides harnessing this rich natural resource, the North Central wind project represents a two-billion dollar investment in Oklahoma's economy. This economic boost comes in the form of construction, operation and maintenance jobs, in addition to increased revenues for schools and infrastructure across the state.

"Many businesses looking to expand or relocate to Oklahoma want to know about our investment in renewable energy," said Simmons. "We're redefining the future of energy and developing forward-thinking solutions that provide both clean and affordable energy to power the communities we serve."

PSO customers looking to achieve sustainability goals related to wind should check out WindChoice - a voluntary green energy offering in which the Company purchases Renewable Energy Credits (RECs) on behalf of the customer. The cost of these RECs is lower than ever before, at less than a quarter of a cent per kilowatt-hour. Contact your account manager for an estimate or more details.
