South Texas Electric Cooperative (STEC)
South Texas Electric Cooperative was formed in 1944 to provide wholesale electric power to member cooperatives. Presently the South Texas Electric Cooperative serves eight distribution cooperatives; Karnes, Wharton County, Victoria, Jackson, San Patricio, Nueces, Magic Valley and Medina electric cooperatives. These cooperatives provide service to over 170,000 members in 65 South Texas counties.
The cooperative’s headquarters are located in Nursery Texas, at the Sam Rayburn generating plant. One hundred and sixty employees are based at the Sam Rayburn plant while another twenty-two are based at the Pearsall generation facility.
STEC’s power is generated utilizing a variety of fuels, including lignite, natural gas, diesel and hydro. These resources include a 50% share in the San Miguel Electric Cooperative lignite generation plant located in Christine Texas; the Sam Rayburn facility which is a combination of resources including dual-fuel, combined-cycle generation; and the Pearsall facility, a gas-fired unit located in Pearsall Texas. The remaining resource is the output of the Amistad-Falcon hydro project.
The South Texas Electric Cooperative (STEC) has also concluded an agreement with Iberdrola Renewables, Inc. for 50 MW of clean renewable energy from the Peñascal project, the first wind project to be built on the Texas coast. This agreement will make STEC’s members the latest electric cooperatives in Texas to integrate clean renewable energy into their generation mix.
