I didn't realize that, and I don't know anything about the SGT6-PAC 5000F/5000. I read that O&G had the EPC contract and I bet it's Algonquin's gas.
Just my personal opinion. 10 plus years experience with GE Frame 7’s, oops, I mean MS7001+e, and 20 years with GE aero derivative gas turbines and a former sister plant with Siemens. Have a shift partner was a FE for Mitsubishi for 5 years.
