The Asian Development Bank, the European Union and the New Zealand government contributed nine million US dollars to the re-opening of the Loto Samasoni, Fale o le Fe'e, and Alaoa hydropower plants.
The Samoa government and the Electric Power Corporation also contributed more than two million dollars.
The heavy flooding at the time of Cyclone Evans in December 2012 caused major damage to the three power stations.
Tuila'epa says the refurbishment and reopening of the plants is part of the government strategy when it comes to power generation.
