Consultancy services for the Millennium Challenge Account–Tanzania (MCA-T)

The Project

The Millennium Challenge Corporation (MCC) is an independent US foreign aid agency that provides eligible countries with large-scale grants, typically of a five-year duration, to fund country-led solutions for reducing poverty through sustainable economic growth.  Once a country is selected, the grant is implemented and managed by an in-country entity, in line with MCC’s aim of country-led solutions and country-led implementation. In Tanzania, the in-country entity was the Millennium Challenge Account-Tanzania (MCA-T).

The aims of the $206 million project, funded by the Millennium Challenge Corporation through MCA-T, were to increase economic activity, reduce poverty and ensure the long-term development of power transmission and distribution networks in Tanzania for future generations.  

ESB International was appointed as Consulting Engineer, for construction supervision, capacity development and technical assistance.
