LCG, May 8, 2025--The Southwest Power Pool (SPP) Board of Directors approved SPP’s proposed Expedited Resource Adequacy Study (ERAS) at its May 6 meeting. SPP developed the new ERAS in collaboration with its stakeholders in response to the growing need to add new generating resources before the region’s generating capacity is outpaced by its electricity demands. ERAS is intended to be a one-time, expedited study process designed to significantly accelerate the addition of new power generation facilities to the grid and address concerns about the near term ability to maintain the affordable and reliable electric service that consumers expect.

Arkansas PSC Approves SWEPCO's Proposed Coal-fired Power Plant
LCG, November 28, 2007--The Arkansas Public Service Commission (APSC) on November 21 granted a Certificate of Environmental Compatibility and Public Need (CECPN) to construct Southwestern Electric Power Company's (SWEPCO's) proposed 600-MW coal-fired power plant in Hempstead County, Arkansas. The target completion date for the project is 2011.
The proposed John W. Turk, Jr. Power Plant will use "ultra-supercritical" technology and will burn sub-bituminous, Powder River Basin coal from Wyoming. The estimated cost of the facility is approximately $1.34 billion. The project site is approximately 15 miles northeast of Texarkana.
In the 2-1 decision issued by the APSC, Chairman Paul Suskie and Commissioner Daryl Bassett voted for the order and Special Commissioner David Newbern dissented.
There are a number of remaining regulatory hurdles ahead of the project. SWEPCO must obtain approval from the U.S. Army Corps of Engineers, the Louisiana Public Service Commission and the Public Utility Commission of Texas. In addition, an air permit from the Arkansas Department of Environmental Quality must be obtained. A draft air permit was issued, and comments are under consideration now. Construction will not likely commence until after the air permit is received.
SWEPCO's planned investment is 73 percent of the capacity, and SWEPCO is pursuing joint ownership arrangements with Oklahoma Municipal Power Authority, Northeast Texas Electric Cooperative, and Arkansas Electric Cooperative Corporation.
