-2 x 500MVA transformers
- 4 x 400kV feeders
- 5 x 132kV feeders
Foundation to the 132kv yard busbar at Borutho construction site
The local communities also benefit from this project as expenditure and resources are localized.  The construction of the project started in January 13 and once completed, will play an integral role in eliminating the voltage collapse in some parts of Limpopo.
