BEST PRACTICES AWARDS: THE BEST OF THE BEST

Effingham County Power gets its fifth Best of the Best Award—tops in the industry—for safe grounding of a generator step-up transformer, eliminating flow-transmitter freeze-up, and other solutions

Nueces Bay and Barney M Davis Energy Centers team up to boost condenser performance

Athens Power Plant reconfigures heat-trace system to assure accurate drum-level measurement

Green Country Energy restores megawatts lost through equipment degradation and improves heat rate as well

Woodbridge Energy Center faced significant follow-up work after commissioning—including a complete overhaul of the outdoor plant’s heat-trace system to survive winters in the Northeast, logic changes to reduce blowdown quench-water use and earn a large financial return, reduce the potential for arc-flash injuries

Riverside Energy Resource Center fine-tunes operations, implements mods, upgrades to reduce startup NOx
