Environmental Strategic Evaluation and Environmental and Social Impact Assessment of 2 Hydroelectric Power Plants in the Keve River

The aim of the Project is to construct two Hydroelectric Power Plants (Main Dam and Flood-Control Dam) in the Keve's river basin, as well as the appropriate power transport line.

Genga dam is 210 m high and 990m long, with 5218 hectares of flood area and a reservoir with a storage capacity of 2 879 000 000 m³. Quilengue Dam is 14 m high and 417m long, with 103 hectares of flood area and a reservoir with a storage capacity of 435 000 000 m³.

The primary purpose of the project is a hydroelectric power generation and its supports a power station with a rated capacity of 900 MW for Genga dam and a rated capacity of 260 MW for Quilengue dam.

The Environmental Strategic Evaluation and Environmental and Social Impact Assessment of 2 Hydroelectric Power Plants in the Keve River included:

- Reference analysis and characterisation of the situation in the area affected by the construction of the ventures concerning different relevant aspects, namely climate, water quality and hydrology, ecology, socioeconomy, air quality, sound environment, architectonic and archaeological heritage, soil occupation and spatial planning;

- Identification and assessment of the environmental impacts concerning these environmental aspects, caused by the Project implementation (during the construction, exploration and deactivation phases);

- Proposition for mitigation measures for a reduction of the significance of identified environmental impacts;

- Proposition for compensatory policies;

- Proposition for monitoring programmes to follow the evolution of the area affected, in the analysed environmental aspects.
