The Tanzania–Malawi Transmission Interconnector is a proposed high-voltage connection between the two national grids. It is intended to increase electricity trade, strengthen supply reliability and support regional power-system integration through transmission lines and substations. A US$2.25 million project-preparation grant was secured in 2025, and the project remains at feasibility stage.
<p> Construction of the Tanzania section of the Tanzania-Malawi transmission interconnector. Tanzania section consists of construction of a 400kV interconnector from Tanzania (KyelaMbeya) to the Songwe border post at the frontier with Malawi.

<p>Traditionally, countries in the region have planned and implemented their power system in an isolated manner with a view to satisfy the national demand growth. Bilateral power exchange agreements exist between EAPP and SAPP countries in the region; however, now SAPP is emphasizing the market participation where EAPP is still developing operationalization of its energy market. The interconnection of Tanzania and Malawi will link the two power pools (EAPP and SAPP) potentially allowing power trade from Northern to Southern Africa creating the longest vital transmission corridor in the world. Both EAPP and SAPP members agreed to interconnect their power systems by developing and constructing a high voltage transmission line system (TOR feasibility study for Tanzania Malawi Interconnector)</p>
<p>The main objectives of this 400 kV Tanzania-Malawi interconnector (hereafter referred to as "the Project") are to: (i) enhance electricity trade through bilateral agreement or market participation; (ii) improve security and reliability of electricity supply; and (iii) foster economic development and regional integration</p>
