[1] The power station is located across the Onive River, approximately 100 kilometres (62 mi), outside of the capital city of Antananarivo.

The dam will be 60 metres (197 ft) high, creating a reservoir with a surface area of 6.7 square kilometres (3 sq mi).

From the reservoir, water will flow through a pipeline that measures 716 metres (2,349 ft) long to arrive at the power house.

[1][2] The project is a public private partnership (PPP), between (a) the Government of Madagascar and (b) a consortium called Nouvelle énergie hydroélectrique de l’Onive (NEHO) or New Onive Hydroelectric Energy Consortium, comprising the French companies Eiffage and Eranove and the company Themis.

In addition, the Arab Bank for Economic Development in Africa (BADEA) and the European Union, are expected to provide further funding for this project.
