Summary: MCC’s $449.6 million El Salvador Compact (2007-2012) extended the electrical grid and provided individual household connections across the Northern Zone of El Salvador through the $30.34 million Rural Electrification Sub-Activity. The Sub-Activity was built on the theory that improving access to the electricity network and shifting use of energy alternatives would decrease indoor air pollution and improve health outcomes, which in turn would increase households’ economic productivity and incomes.
