The scope of supply includes complete gas turbine blocks including all main components and auxiliary
equipment, buildings and enclosures, spare parts and relevant documentation including operation and
maintenance manuals. The supply boundaries are the fuel booster pump inlet and the terminals on the generator
breaker connection to the 10 kV switchgear. Boundaries of other connections to equipment not forming part of
the unit are at the terminal points in the unit.

1 12 MW PP3 GAS TURBINE
The plant was built in 1972 - 1973 to cover the peak electricity demand of the company. The
plant has been used sparsely, mainly for test runs. The plant is officially decommissioned, but
operative and in good condition and has been regularly maintained.
