Background on Plant

The Arnot Power Station is a coal-fired station owned by the South African publicly-owned electricity utility Eskom, located at Middelburg, Mpumalanga. Construction of Arnot started in 1968, and was commissioned from 1971 to 1975.[1]

The power station comprised six units of 350 MW each. In 2008 Eskom said it planned to commission 60 megawatts upgrades in 2008, a further 60 megawatts in 2009 and a further 30 megawatts in 2010.[2]

In 2015 Eskom gave the unit ratings as follows: 1 x 370 MW; 1 x 390 MW; 2 x 396 MW; 2 x 400 MW for a total of 2,352 MW installed capacity and 2,232 MW nominal capacity.[3]

Proposed renewal

In April 2016 the Eskom Board said it approved the commencement of a pre-feasibility study for renewal options for four of our oldest power stations - Komati, Camden, Hendrina and Arnot. The pre-feasibility study would take 18 months to complete, and would include looking at options such as plant life extension.[4]
