Uganda Electricity Transmission Company (UETCL), a government owned company is the only utility in Uganda licensed to buy in bulk and sell in bulk electricity. The utility purchases electricity from domestic electricity generation utilities on the grid and neighboring countries. Electricity purchased is then sold in bulk and to grid-connected distribution companies within and outside the country.
UETCL Energy Purchases
UETCL purchased 3,867.1 GWh in 2017 as compared to 3,549.0 GWh in 2016 signifying a 9% increase. Of the total energy purchased in 2017, about 99.7% was purchased from local electricity generation utilities while 0.3% was imported. Energy imported reduced from 137.4 GWh in 2016 to 21.3 GWh in 2017. This reduction in energy importation is due to the increased capacity from the domestic electricity generation utilities.
UETCL Energy Sales
UETCL sold the energy to UMEME (U) Limited, mini-grids and neighboring countries. The utility sold 3,715.9 GWh in 2017 as compared to 3,400.1 GWh that was sold in 2016 giving a 9% increase. Most (90%) of the energy sold in 2017 was purchased by UMEME (U) Limited. Energy sold to mini-grids constituted about 2% while 8% was exported. The countries to which UETCL exported electricity included to Rwanda, Tanzania, Democratic Republic of Congo and Kenya.
Transmission System Losses
Transmission losses are computed as the proportion of energy purchased that was not sold. The utility recorded a transmission loss of 3.9% in 2017 as compared to 4.2% in 2016. Whereas UETCL observed a drop in transmission system losses in 2017 as compared to 2016, this was still higher than the 3.38% set and approved Transmission Loss Factor (TLF) for the year.
