“When they are completed, the Patriot and Liberty power plants will be two of the most technologically advanced modern power plants on the East Coast,” said Martin Tartibi, Head of the Business Unit Gas Turbine Power Plant Solutions Americas at Siemens Energy’s Power Generation Division. “Our H-class gas turbines mean that Pennsylvanians will have a cost-efficient, environmentally friendly electric power supply for many years to come.”
Siemens Energy has been awarded an order to supply two integrated power islands, both fitted with H-class gas turbines for the Patriot combined-cycle power plant (CCPP) in Pennsylvania. In combined-cycle duty it will have a generating capacity of 829 megawatts (MW).
The completed power plant will be built by Gemma-Lane Patriot Partners, a leading engineering, procurement and construction contractor in the US. The Siemens contract is reportedly worth $400 million USD and includes a long-term maintenance and service contract. The plant is scheduled for commission in 2016.
Patriot CCPP is to be located in Clinton Township and will fire local shale gas. It will also have two power islands, each designed as single-shaft configurations, meaning the gas turbine and the steam turbine are arranged on one shaft and drive the same generator. This will result in lower investment costs as well as high degree of flexibility during operation. Siemens will supply two integrated power islands for the plant, each consisting of one SGT6-8000H gas turbine, one SST6-5000 steam turbine, one hydrogen-cooled SGen6-2000H generator and one heat recovery steam generator, in addition to the complete electrical system and SPPA-T3000 instrumentation and control system.
