Evaluated prospects

  • Studies: BRGM (1982-

1983); Chevron (2006)

  • Reconnaissance and

limited surface exploration carried out in the Western (Rusizi, Rubavu and karongi), Southern (Karaba)and Northern (Musanze and Nyabihu) parts of the country

  • 18 hydrothermal and

mineralized springs identified and analyzed

slide-12
SLIDE 12

Geothermal zones:

Volcanoes National Park

The National Volcanoes in the Northern part of Kivu Lake comprises eight big volcanic

  • structures. Five of them are

situated in Rwanda:

  • Muhabura
  • Gahinga
  • Sabyinyo
  • Bisoke
  • Karisimbi
slide-13
SLIDE 13

Geothermal zones:

Cyangugu zone

Located in the Southern part of Kivu Lake. It is situated in the Eastern part of the distensive system on Rusizi Graben with an

  • rientation similar to the

National volcanoes system N-S. The hydrothermal manifestations (hot springs and the travertine deposit) are linked to this type of structure.

Ongoing study

Geothermal Resource assessment

An implementation agreement for a joint geothermal

assessment and capacity building project signed in November 2007 between the Government of Rwanda (GoR) and the German Federal Institute for Geosciences and Natural Resources (BGR)

Study area: Gisenyi –Volcanoes area Geological analysis , geochemical sampling of springs

and Geophysical exploration in the study area completed in collaboration with the Kenya Electricity Generating Company KENGEN .

Capacity building

WB geosciences and geothermal capacity building

needs assessment completed.

Training of four Rwandans in a short course on surface

exploration for geothermal resources (2007, 2008) in Kenya

Training of one Rwandan for a six month course (April-

October 2008) at the United Nations University Geothermal Training Programme (UNU-GTP)in Iceland

Contact made with the UNU-GTP for training of more

Rwandan candidates in Iceland for the years 2009-2011

Detailled geophysical surveys in the Gisenyi-

Volcano area

Drilling of exploratory wells on the promising

area

Development of a pilot power plant Detailled geological, geochemical and

geophysical surveys on promising sites.

More training of Rwandans for each steps

Conclusions Conclusions

slide-23
SLIDE 23

Development of geothermal energy : A priority

for the Government of Rwanda

Evaluate properly Rwanda geothermal resources Look for financing for the development of geothermal

energy

Assistance for training of experts required in Rwanda Participation of private and public partnership in the

sector is encouraged

Existence of incentives to attract private sector

investments in the sector

Rwanda to be a member of and benefit from the

African Rift Geothermal Development Facility
