History of the Units
The two model EM610B open cycle, single shaft, gas turbine
sets, manufactured by GEC Gas Turbines Limited (UK) and
commissioned in 1981. Originally installed in 1980, and
operated until 1991, the gas turbine sets were relocated and
re-commissioned in 1992. They were available for service
through until 1998 when they became surplus to generation
requirements. They are currently dismantled under preservation.
The operating hours/starts for the two units are 598/825 and 910/975 respectively.
