Hydropower Country Notes
Madagascar has a considerable land area (greater than that of France, for example) and heavy annual rainfall (up to 3 600 mm). Consequently, the potential for hydropower is correspondingly large: gross theoretical potential is put at 321 TWh/yr, within which the technically feasible potential is 180 TWh/yr. With current installed capacity standing at 105 MW and annual hydro output about 540 GWh, the island's hydro capability has scarcely begun to be utilised.
There are two HPPs of over 10 MW capacity: Mandraka (24 MW) and Andekaleka (58 MW). Financing has been arranged for an additional 29 MW unit at Andekaleka, while two small hydro plants are under construction at Sahanivotry (12 MW) and Lily (3.5 MW), with all three expected to be completed during 2007-2008.
