The Combined Cycle Users Group (CCUG) was launched in fall 2011, at its first meeting in San Antonio, as an independent, user-directed group to serve owner/operators of combined-cycle, combined heat and power (CHP), and cogeneration plants. The CCUG is distinguished by the logo shown here and not affiliated with any other group of the same or similar name, nor is it associated with any other industry event.
The organization’s meetings are dedicated to formal presentations and attendee-driven discussion sessions focusing on the design, construction, operation, and maintenance of the integrated plant. Additional topics addressed include NERC and other regulatory impacts on planned operation, environmental rulemakings, plant mods to achieve performance goals, safety initiatives, professional development, skills training, etc.
