Siemens Energy has received an order to supply two integrated power islands fitted with H-class gas turbines for the Patriot combined-cycle power plant (CCPP) in Pennsylvania. It will have a generating capacity of 829 megawatts (MW) in combined-cycle duty. This is the second project awarded by Panda Power Funds in Pennsylvania following the Liberty order announced in August of 2013. The complete power plant is to be erected by Gemma-Lane Patriot Partners, a leading Engineering, Procurement, and Construction contractor in the U.S.A. The order volume for Siemens, including a long-term maintenance and service contract, is approximately USD 400 million. Commissioning of the plant is scheduled for 2016. This order marks the 27th H-class gas turbines sold by Siemens worldwide.
Patriot CCPP, which will fire local shale gas, is to be erected in Clinton Township in Lycoming County in the U.S. state of Pennsylvania. Like its sister plant Liberty CCPP, Patriot will also be comprised of two power islands, both designed as single-shaft configurations, meaning that the gas turbine and steam turbine are arranged on one shaft and drive the same generator. Single-shaft units offer economic advantages thanks to their low investment costs, excellent efficiency and a high degree of flexibility during operation. Patriot and Liberty power stations will be able to supply up to two million homes with clean power.
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, along with the complete electrical system and SPPA-T3000 instrumentation and control system. In addition, Siemens will provide maintenance and service for the main components associated with the gas turbine under a long term service program. Parts, inspections, and scheduled service/maintenance, along with Siemens’ Power Diagnosticsremote monitoring and diagnostics, are included in the comprehensive service agreement.
