Impacts of low-cost-connection offers:

  • Increased connection rates by 13 percentage points.
  • Increased electricity consumption, consumption of grid electricity, ownership of electric tools, time spent watching television, and perceived safety.
  • Increased reported illness among children and youth.
  • Reduced poverty, as measured by per capita daily 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 low-cost-connection offers in Tanzania.
