A major high-voltage line linking Zambia to Tanzania that will boost regional electricity ​trading and reliability is expected to start ‌operations in 2029, Zambia’s electricity minister Peter Kapala told lawmakers on Thursday.

The project, agreed in 2014, involves ​linking Zambia to Tanzania and Kenya via ​a 2,300 km (1,429 mile) transmission power line ⁠built at an estimated cost of $1.2 billion.

Zambia, which ​secured grant funding of $292 million from the World ​Bank Group, EU and UK, will build just over 600 km of power lines.

Once complete, the interconnector will ​link the Southern Africa Power Pool (SAPP) to ​the Eastern Africa Power Pool (EAPP), enabling Zambia to trade up ‌to ⁠500 megawatts of power and positioning the country as a regional hub for electricity trade, Kapala said in a statement.

Last month, China’s Sinotech ​Consortium was awarded ​the ⁠first phase covering 186 km from Pensulo substation to Mpika and the ​second 200 km from Mpika to ​Kasama substation ⁠in northern Zambia, he said.

“The full scope of the Zambia-Tanzania interconnector project will be undertaken in ⁠24 ​months and is therefore ​scheduled to be commissioned by the second quarter of 2029,” Kapala ​said.
