Pioneer Generation Station Phase IV

The Phase IV expansion of Pioneer Generation Station adds 583 megawatts (MW) to the existing facility by integrating simple-cycle combustion turbines and reciprocating engines to support load growth. The two technologies are being installed parallel, a half-mile apart, at either end of the existing facility.

Basin Electric selected AZCO and Burns & McDonnell to engineer, procure and construct (EPC) its largest single-site generation plant since the 1980s.

The EPC team established upfront project development efforts, including environmental permitting, collective initial planning, and responsive decision-making, to support the EPC and startup/commissioning professionals on the project.

Our construction scope includes mechanical installation of a series of six 18-MW Wartsila W18V50SG reciprocating engines and two 240-MW Siemens STG6-PAC-5000F combustion turbines.

We installed all the below-grade utilities including piping, tank setting and electrical duct banks. The above-ground scope consists of structural steel erection, inlet filters, centerline equipment installation, exhaust ductwork and stacks, electrical equipment setting, tank setting, electrical raceway installation, cable/wire pulling and terminations, instrumentation, and miscellaneous balance-of-plant (BOP) equipment setting associated with piping and startup support.
