The small hydropower plants will generate 35 megawatts of electricity, he said.

Seven small hydropower plants, including one in Savaii, were commissioned last year as part of Samoa's renewable energy project.

Tologata said the corporation needed more rain to help small hydropower plants generating electricity to help feed the main power station.

The firm planned to invest in clean power generation assets -mainly wind, solar, geothermal energy, small hydropower and biomass projects.

Reuters reported in August that Cemig had hired investment banks to manage the sale of small hydropower dams and a gas distribution unit.
