History: In
1965/66 contractors started with roads, pipelines and ground works on the farm
Rietkuil, which Eskom bought from seven owners. Sufficient water and especially
coal supply in the Rietkuil area ensured that the construction of Arnot Power
Station commenced in 1968. Arnot was Eskom's first modern coal-fired power
station and was fully operational by June 1975. Three of its units were put into
reserve storage (mothballed) in 1992 due to the surplus generating capacity
Eskom had at the time. The units were recommissioned in January 1997, November
1997 and December 1998 respectively. The station is 31 years
old. General: Two 400kV transmission lines, owned
by MOTRACO, run from Arnot and Camden power stations to a substation near Maputo
in Mozambique, feeding the new MOZAL Aluminium
smelter. Technical details:
