RAKOLA GRID EXTENSION PROJECT
The Corporation has undertaken a project to construct two (2) parallel 220kV lines (80km each) from the existing Isang’s Ranch 400/220kV substation (near what is commonly referred as Mosaditshwene, along the A1 highway) to a new 220/132kV substation in Rakola lands (about 6km west of Gabane village). The project also consists of a 132kV line from Rakola to Gaphatshwa where a 132/33/11kV substation will be erected.
The progress to date is as indicated below.
2 x 220 kV lines from Isang to Rakola:
This tender was awarded to Kalpataru Power Transmission Limited of India through a competitive open tender method, with a contract duration of 14 months.

The line contractor is now waiting for the substation contractor to complete all the relevant substation works in order to finish the 5% of outstanding lines work.
Rakola 220/132kV substation:

This noble gesture has earned this contractor certificates of appreciation from Gabane, Gakutlo and Kgope Tribal Administration. They also received certificate of appreciation from as Department of Forestry and range Resources for Environmental Friendly Practice.
The first two components (Rakola substation and 2 x 220kV lines) of this project are expected to be completed in August 2017 while the planned completion date for the last component is April 2018.
Once completed, the infrastructure will improve the reliability and security of electricity supply in the southern region of the country since currently the 2 x 220kV transmission lines from Isang’s Ranch substation to Segoditshane (in Gaborone) and Thamaga substations are constrained for capacity during peak.
