3. Operating hours since last OH:

GT-91 - 26,275 OH, 29,395 EOH,

GT-92 - 23,475 OH, 26,375 EOH

Equipment may be in need of an overhaul. BUT RUNNING WHEN SHUT DOWN

Please note that these units located in the USA were operated at 60 cycle - 13,800 volts

Both Plants must be purchased , a Heat recovery is also available with each Turbine.

Note: The heat rate on these turbines are as good as the newer high temp Turbines.

These were originally 50 hz, with reduction gear modification for 60 hz, could go back.

Price is 5.25 Million USD each

HRSG is needed @ $400,000 each

Gear modification to 50 hz expected @ $450,000 For more information ask by Email
