Tanzania and Kenya have joined forces to construct a 400 kV interconnection line that runs from a proposed 400 kV substation at Isinya near Nairobi in Kenya up to Arusha in Tanzania (210 km) and further to a planned 400 kV substation in Singida (300 km). Works in Tanzania are divided into 6 lots as follows:
- Lot T1: 400 kV double circuit OHL between Singida and Babati (approx. 150 km)
- Lot T2: 400 kV double circuit OHL between Babati and Arusha (approx. 150 km)
- Lot T3: 400 kV double circuit OHL between Arusha and the Kenya border (approx. 114 km)
- Lot T4: New 400 kV Arusha substation and extension of the existing 220/33 kV Singida Substation (two additional 220 kV line bays, three breakers and two shunt reactors)
- Lot T5: Rural electrification projects (approx. 80 km of 33 kV lines and low voltage system including customer connections)
- Lot T6: Four new 400 kV substations in the towns of Iringa, Dodoma, Singida and Shinyanga
