Generate Reliable and Clean Power With an Integrated EPC Solution

CPV contracted a joint venture with Burns & McDonnell, Skanska USA Civil Northeast and ECCO III Enterprises for engineer-procure-construct (EPC) services on the combined-cycle CPV Valley Energy Center in Wawayanda, New York.

Maintaining close collaboration with CPV and all parties, our team provided engineering, procurement, construction, and commissioning and startup services for the dual-fuel plant. CPV Valley Energy Center incorporates two Siemens SGT6-5000F combustion turbine generators matched with two supplementary-fired heat recovery generators (HRSGs) with kettle-boiler type rotor air coolers. The design also features three SGen6-1000A generators, one Siemens SST6-5000-KN side exhaust condensing steam turbine generator and a 36-cell induced draft air-cooled condenser.

To deliver reliability and maximize efficiency, each combustion turbine is designed to be capable of operating at full load in a pseudo simple-cycle mode, in which steam from the corresponding HRSG bypasses the steam turbine and is bypassed to the condenser. Through the commissioning process, our team utilized the facility’s backup supply of ultra-low-sulfur diesel (ULSD) fuel for startup while a pipeline was completed to deliver the plant’s primary fuel source, natural gas. This dual-fuel flexibility increases CPV Valley Energy Center’s availability during cold weather peak demands, when gas supplies may be curtailed to industrial customers.

The teams also incorporated design features to reduce the facility’s impact on the environment, including the use of reclaimed water from a nearby wastewater treatment plant as a source of make-up water for power production. The design allows process water, cooling water, boiler blowdown and wastes produced on-site to be discharged back to the wastewater treatment plant for re-treatment and reuse.
