Design Data
The two model GT 13D open cycle Asea Brown Boveri (ABB) gas turbines were original installed in 1980, and operated until 1992, the gas turbine sets were relocated and re-commissioned at another site in 1993. The units were available for service through until 1997 when they became surplus to generation requirements. They are currently under preservation.
