Pratt & Whitney Power Systems

PW Power Systems, formerly Pratt & Whitney Power Systems, was acquired by Mitsubishi Heavy Industries, Ltd., in May 2013 and changed its name to PW Power Systems, Inc. (“PWPS”). The agreement made between MHI and Pratt & Whitney includes exclusive access to Pratt & Whitney advanced technology, future development rights to Pratt & Whitney aero-engines, as well as ongoing engineering and aero-engine production.

PWPS has over 2,000 gas turbine units installed and has designed and built 300 turnkey systems. PWPS offers both simple and combined-cycle units which have accumulated over 19 million operating hours. PWPS has expanded its product line to include aero-derivative gas turbines from 30-140 MW including the FT8® MOBILEPAC® or FT8® and FT4000® SWIFTPAC® package configurations as well as Industrial Gas Turbine (IGT) Parts/Repairs, and Engineering, Procurement, and Construction (EPC) of turnkey systems.

FT4000® Next Generation Gas Turbine Package

The FT4000® next generation gas turbine is based on one of the aviation industry’s most widely utilized aircraft engines: the flight-proven PW4000™ class turbofan engine which has 34 million hours of flying time logged by some 900 engines in aircraft service.

Designed for simple-cycle, combined-cycle, or cogeneration, and available in 60-70 or 120-140 MW power blocks, the FT4000® SWIFTPAC® package provides the highest power output of any aero-derivative gas turbine generator package available in the market.

With a modular design that includes proven features of the successful FT8® SWIFTPAC® and MOBILEPAC® power plants, the FT4000® SWIFTPAC® packages offer a nominal 60 MW up to 140 MW package of reliable peaking and base load power in a compact footprint. The SWIFTPAC® product design accommodates a 60-70 MW single-engine or a 120-140 MW dual-engine configuration, and provides the operational flexibility inherent with aero-derivative turbines including quick start characteristics.

The FT4000® SWIFTPAC® package utilizes a modified core compressor and turbine from its aero parent and maintains more than 90 percent part commonality with the PW4170 and PW4090 engines. The product’s new low pressure compressor and industrial power turbine are designed for durability and enhanced on-site maintainability. Its high speed and advanced airfoil design and variable geometry translate into optimized performance. The new package also provides wet compression for improved performance above ISO conditions and offers greater than 41 percent efficiency without the complexity and high water usage of intercooling.

FT8® MOBILEPAC® Gas Turbine Package

The MOBILEPAC® product utilizes the FT8® gas turbine in a proven package that provides quick, reliable power especially in emergency situations.

The MOBILEPAC® package consists of two trailers. The first contains the gas turbine, electric generator, exhaust collector, diffuser, and engine lube oil system. The second trailer carries the 15 kV switchgear, control system, operation panel, protective relays, batteries and charger, motor control center, and the hydraulic start package. A pre-commissioned MOBILEPAC® gas turbine package can be driven to a site and begin generating power in nine days or fewer.

FT8® SWIFTPAC® Gas Turbine Package

The FT8® SWIFTPAC® gas turbine power plant provides quick, reliable power in fewer than 30 days. The FT8® SWIFTPAC® package offers 30 or 60 MW of power. Utilizing FT8® technology derived from the Pratt & Whitney® JT8D™ derivative gas generator, the SWIFTPAC® power plant is designed as a fully assembled enclosure incorporating the gas generator, power turbine, exhaust collector box, inlet plenum, and lube system. These factory-assembled modules allow the FT8® SWIFTPAC® power plant to be up and generating power quickly. The SWIFTPAC® can be configured for simple-cycle or combined-cycle operation from 30 to 60 MW of power. In a 2×1 combined-cycle arrangement, the FT8® SWIFTPAC® can provide up to 173 MW of power.
