Key Findings

The line extensions led to:

  • A large number of new connections, though less than one-third of the number assumed.
  • Increased consumption of grid electricity, ownership of electric tools, operation of income generating activities using grid electricity, time spent watching television, and perceived safety.
  • Increased percentages of communities with an electrified school and electrified businesses.
  • No clear changes in pollution, health, income, or consumption.

The Millennium Challenge Corporation’s energy-sector project was designed to promote economic growth and curb poverty in Tanzania. Mathematica conducted an evaluation of two project components: impacts of building new lines to the electricity grid and outcomes from offering low-cost-connections to households in a subset of communities. This brief summarizes the impacts of creating new electric line extensions in Tanzania.
