Siemens to upgrade 500 MW natural gas-fired plant

24 February 2009 — Klamath Energy LLC, a unit of Iberdrola Renewables, gave Siemens Energy Inc. an upgrade order for a 500 MW natural gas-fired cogeneration plant in Oregon. The order includes combustion turbine parts and service, generator rewinds and modernization upgrades, an inlet heating system, a combustion dynamic protection system and the SPPA-T3000 control system. The upgrades are slated for completion by mid-2010.

The upgrade scope for the two SGT6-5000F combustion turbines at the gas-fired Klamath cogeneration combined cycle plant will increase base load plant power and improve plant base load heat rate.

The inlet heating system is designed to provide more efficient gas turbine operation during colder weather and at lower loads. The contract also includes generator stator rewinds on both combustion turbines and the installation of the SPPA-T3000 control system.
