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.
