Environmental Impact Assessment (EIA) report : augmentation phase of Afulilo Hydro Power Scheme, Samoa / prepared by Komeri Onorio and Bale Tamata for the Government of Samoa.

Abstract

The Afulilo Hydro Power Augmentation Project was designed specifically to assist with the Upolu power system stability. Demand for energy has been growing in line with growth in maximum demand and, while the Afulilo scheme is producing more energy than anticipated, the sustainable energy outflow of the present scheme is limited by water inflows, reservoir storage volume and installed generation capacity. Because the Afulilo scheme is the only hydro scheme in Samoa with carry over storage, augmentation of the Afulilo scheme is paticularly important to increase dry season capacity to reduce the amount of installed diesel capacity to reduce overall fuel consumption and to lessen the dry season peak in fuel consumption.
