Nigeria: Growth in Electricity Transmission Network [free access]

December 7, 2021

At the end of 2020, the country’s transmission network comprised about 17,463 km of transmission lines between the 132 kV and 330 kV voltage levels. Since 2016, transmission line length has witnessed slower growth at a CAGR of 2.69 per cent.

 

Nigeria’s transformation capacity has increased at a CAGR of 5.55 per cent since 2016 and stood at 30,197 MVA by the end of 2020. Of this, 55.8 per cent was at 132 kV, and 44.2 per cent was at 330 kV. The number of substations increased from 164 in 2015 to 200 in 2020 at a CAGR of 5.09 per cent.
