The Combined Cycle Users’ Group (CCUG) was formed to address issues of importance to users, particularly the interactions among the major systems of combined-cycle power plants: the steam turbine, combustion turbine(s), and heat-recovery steam generator. The added value of becoming a CCUG member is the opportunity to interact with other operators, as well as designers, of combined-cycle plants at their annual conference, May 2–4 at Electric Power 2006. Sharing experiences and information is an underappreciated approach to solving the technical and operational problems you face today. For more information, visit or
