CHP repowering order for Siemens in US

Siemens Energy Inc. has been awarded a service programme order for the Klamath Energy cogeneration plant in Klamath Falls, Oregon, USA.

The deal with Klamath Energy LLC, owned by Iberdrola Renewables, includes combustion turbine parts and service, generator rewinds and modernization upgrades, an inlet heating system, a combustion dynamic protection system (CDPS) and the innovative SPPA-T3000 control system. The upgrades are expected to be completed by mid-2010.

The upgrade scope for the two SGT6-5000F combustion turbines at the 500 MW rated, gas-fired Klamath plant is intended to increase base load plant power and improve base load heat rate.

The inlet heating system is designed to allow for 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 innovative SPPA-T3000 control system. The long-term maintenance programme also includes a Siemens warranty.

‘The result is a highly flexible resource with 636 MW of capacity that fits perfectly with our growing portfolio of renewable resources’, said Peter van Alderwerelt, senior vice president, Iberdrola Renewables.
