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!
The 7F Steering Committee and Power Users board are diligently working to have an “In-Person” conference in 2021. In an effort to do this, we have moved the 7F Users Group annual conference in St. Louis to the week of August 23rd! We look forward to seeing everyone in person again.
