Get better performance, more output from combined cycles, generators, steam turbines, controls

Don’t delay. Register today.

The 2018 Power Users’ Combined Conference, featuring separate meetings for the Combined Cycle, Steam Turbine, Generator, and Power Plant Controls Users Groups in one venue, is only a month away. Register before July 27 to receive the early-bird discount. 

Marriott Louisville Downtown, August 27-30. Book your room by August 3 to receive the preferred conference rate. 

The four organizations come together at all meals and the vendor fair, so there’s good opportunity to connect with colleagues having different areas of expertise and benefit from their experiences. Plus, you can attend sessions at all four meetings by just registering for the one of greatest interest. The program guide you’ll receive at registration shows at a glance what’s going on in each of the meetings at any point in time.

Conference Manager Sheila Vashi of SV Events predicts conference attendance will be the largest ever.  This will be the eighth annual meeting for the CCUG, the fifth for the STUG, the fourth for the GUG, and first for PPCUG.

Highlights of each meeting follow. If you are unfamiliar with these groups, bear in mind they are not commercial ventures. The technical programs were developed by your user colleagues and the meetings are conducted by Power Users—an umbrella organization established by users to hold down costs and eliminate promotional content that often dominates commercial meetings.

Combined Cycle Users Group (CCUG)

Key topics addressed in discussion forums and formal presentations include the following:

    • Maintenance. Attemperators; chrome piping issues; impact of gas-turbine turndown on the HRSG, steam turbine, and balance-of-plant equipment; repetitive cold-reheat piping failures and resolution.

    • Inspections/audits. High-energy piping; heat-recovery steam generators; drain and isolation valves; pipe hangers; detection of underground leaks in cast-iron, high-density polyethylene, and other piping.

    • Process/compliance. NERC/CIP; impact of renewables on combined-cycle plants; plant dispatch drivers and their availability impacts; energy imbalance market fundamentals; making plants flexible, resilient, and fast-start capable.

    • Other. Operator training, safety in gas handling; best practices; human-performance initiatives and procedures.

    • OEM technology workshops (Siemens and GE).

You may be thinking, “What’s a PPCUG?” Well, according steering committee chairman, Peter So of Calpine, it’s the missing link to the Power Users’ Combined Conference. Key topics addressed in discussion forums and formal presentations at the inaugural symposium include the following:

    • Controls.

    • Hardware.

    • Software.

    • Instrumentation.

    • Cybersecurity.

    • Digital transformation.
