When it comes to the need electricity Hanga Abbey and its institutions understand it quite well. Hanga Abbey have had small hydroelectric power plant which produces about 40kW. This power is not all enough to cater all the needs for power for the abbey, its schools, workshops, and not to mention the villagers. Recently the abbey approached the Manager of electric company at Songea, a nearby town where public electricity is available, for a possibility of supplying the electricity to Hanga a distance of 50 kilometers. The answer was had that for municipalities like Songea, it has a jurisdiction of supplying power within a distance of 30km only. But there is hope because within two years 2013/14 there is a plan of bringing electricity from the National Electric Grid System to Songea. It that happens Hanga will be saved.

Due to insufficient supply of electricity individual institutions like St. Benedict, Hanga dispensary and St. Laurent have solar power electricity for lighting.
