7F Users Group

7F Users Group, Inc. has grown dramatically since its first meeting in Baltimore, November 19-20, 1991, attended by 14 O&M personnel from four companies. The only 7F engine in service at that time was Virginia Electric & Power Co’s Chesterfield 7. It had been integrated with an existing steamer and new heat-recovery steam generator to configure a 1 x 1 combined cycle.

Fast forward to today: The OEM has shipped to customers more than 1000 F-class gas turbines since Chesterfield 7 left the shop. the majority of these units are 7FAs.

Mission Statement of the GE7FA Users Group

7F Users Group, Inc. is organized to provide an open forum through conferences and technological aids to the Owners/Operators of 7F Combustion Turbine generator systems for effective communication, discussion, and information dissemination regarding the operation, maintenance, inspection, troubleshooting, and repair of such systems to maximize equipment performance and reliability. These purposes will be achieved through providing an opportunity at meetings, conferences, company email, and website for the open exchange of ideas between owner / operators and owner / operators with vendors.

This site is managed by Users for Users!

We have great news for the 7F Community!!

Coming Soon…

2020 7F User Group Annual Conference – WebEx Series

Free for Users!

Due to the COVID-19 pandemic, the 7F Steering Committee, with support from Combined Cycle Journal, will be hosting a WebEx series, which will begin in mid-June. We recognize that this will in no way replace the value of a face-to-face conference. Our goal at this time is to keep the 7F Users Community connected and informed.

We NEED YOU, User Presenters, to make this happen. Please let us know if you have interest in presenting.

• Let us know: Email 7F Steering Committee at SteeringCommittee@7Fusers.org with your topic and a brief description.
• Topic Areas (but not limited to): Best Practices, Lessons Learned, Design Changes, Outage or Equipment Experience

GE and Vendor presentations are also being organized. More details coming in mid-April.
