2021 BEST PRACTICES AWARDS: Eight plants earn Best of the Best honors in CCJ’s annual Best Practices program – Combined Cycle Journal

2021 BEST PRACTICES AWARDS: 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 gas-turbine users groups—including 7F, 501F, 501G, 7EA, Western Turbine, Frame 6, 501G, 501D5-D5A, AOG, and V—collaborate to expand the sharing of best practices and lessons learned among owner/operators of large frame and aeroderivative gas turbines.

Thirty-one plants listed below participated in the 2021 Best Practices Awards program with eight selected by industry experts for Best of the Best honors. Details of the Best Practices submitted will be published in future issues.

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, outage management, 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.
