Eight plants earn Best of the Best honors in CCJ’s annual Best Practices program – Combined Cycle Journal

Eight plants earn Best of the Best honors in CCJ’s annual Best Practices program

The COMBINED CYCLE Journal and the steering committees of the industry’s leading user groups—including 7F, 501F, 7EA, Western Turbine, Frame 6, 501G, 501D5-D5A, AOG, and Combined Cycle—collaborate to expand the sharing of best practices and lessons learned among owner/operators of large frame and aeroderivative gas turbines.

Fifty plants participated in the 2020 Best Practices Awards program with eight selected by industry experts for Best of the Best honors (see below). Details of the Best Practices submitted by all entrants will be presented in the coming months on CCJ ONsite.

CCJ launched the industry-wide Best Practices Awards program in late 2004. Its primary objective, says General Manager Scott Schwieger, is recognition of the valuable contributions made by plant and central-office personnel to improve the safety and performance of generating facilities powered by gas turbines.

Industry focus today on safety and performance improvement—including starting reliability, fast starting, thermal performance, emissions reduction, and forced-outage reduction—is reflected in the lineup of proven solutions submitted this year.
