TG Advisers Power Plant Training: Steam and Gas Turbines, Generator, and Control System Training – Las Vegas

September 23 @ 1:00 pm - September 27 @ 11:30 pm


This course is designed for power plant maintenance and operations personnel, plant engineers and central staff, and loss control engineers responsible for fossil/aero-derivative, nuclear, simple cycle and combined cycle power plants equipment. The course will introduce key design aspects of turbines and generators, failure modes and emphasize risk informed repair and life extension strategies. The course will also offer best practices and maintenance considerations for flexible operation which typically includes more cycling, lower minimum loads, and greater capacity ratings. All modules are supplemented with current case studies demonstrating the applied techniques.


DATES: September 23 – 27, 2024

COST: $3,250 per person (10% discount for 3 or more from same company – must register and pay at the same time. Attendees from the same company may register for any of the 3 courses being held at this location and still receive the discount.)

LOCATION: 4315 University Center Dr. Las Vegas NV 89119.
