La Paloma switches to Siemens turbines at planned Texas plant

American Electric Power Service Corp., on behalf of its affiliate AEP Texas Central, on July 2 filed with the Federal Energy Regulatory Commission a Second Amended and Restated ERCOT Standard Generation Interconnection Agreement dated June 9 between AEP Texas Central and La Paloma Energy Center LLC.

The commission initially accepted the original ERCOT SGIA in October 2014, then accepted a First Amended and Restated agreement on March 17.

The parties now agree to amend and restate the agreement for the purposes of adding six months to the schedule for the generator’s notice to commence construction, decreasing plant capacity from 758 MW to 730 MW, and revising generating unit turbine types.

The plant is now defined as a nominal 730-MW facility comprised of two units at 230 MW each and one unit at 270 MW. It will consist of two Siemens air-cooled combustion turbine generators and one Siemens hydrogen-cooled steam turbine generator. It had previously consisted of two General Electric 7FA.05 combustion turbines and one Hitachi steam turbine.

La Paloma’s Fuerza Substation will be located at 24684 FM 1595 at Harlingen in Cameron County approximately 0.3 miles east of FM 509 in Harlingen, Texas. There will be three Points of Interconnection, each located at one of three dead-end structures inside AEP Texas Central’s Potencia 345 kV/138 kV Station.
