Addis Ababa, - Djibouti and Ethiopia are developing new geothermal power capacities that are intended to enable them meet increasing demand for electricity and enhance their sustainable-energy portfolio.
The World Bank has provided details about its contractor prequalification procedure for the drilling of four full-size geothermal production wells in Djibouti, while Icelandic powerplant builder Reykjavik Geothermal says it hopes to commence its $2-billion Corbetti Geothermal Power Project in Ethiopia in July.
The World Bank, one of the financiers of the $31-million Djibouti Geothermal Power Project, which is being developed by another Icelandic firm, Reykjavik Energy Invest, advertised the invitation for bids from qualified drilling companies to execute the project. Funds will come from a number of institutions.
The bank said the steam-well drilling program entails civil engineering preparatory works, to be funded by the African Development Bank (AfDB) at Lake Assal geothermal field.
The second component—the actual drilling of the four wells—is co-financed by Global Environment Facility, the OPEC Fund for International Development and the World Bank's International Development Association (IDA).
French financier Agence Française de Développement (AFD) will fund the acquisition of steel material needed during the execution of the drilling program, while the inspection and testing of reservoir flow rates will be supported by Energy Sector Management Assistance Programme.
Technical assistance support will be provided by the AfDB for designing the drilling program and the well test protocol by a geothermal consulting company yet to be named.
The final component would involve executing the well test protocol and ensuring third-party certification of the results of the drilling program before preparing a technical feasibility study for the geothermal power plant, “provided that the geothermal resource is suitable for power generation.”
Djama Guelleh, Djibouti’s head of electricity, said if the geothermal resource is proven to be commercially viable for large-scale power generation, “a follow-on project will be undertaken to competitively offer the geothermal resource to the international independent-power-producer market.”
The project, to be developed under a public-private partnership, would help Djibouti cut reliance on imported electricity from neighboring Ethiopia and meet the country’s peak demand of 70 MW, of which Ethiopia meets 65%.
In Ethiopia, which gets up to 90% of its 2,000-MW installed power-generating capacity from dams, Reykjavik Geothermal said in March it will, by next July, commence the development of the $2-billion geothermal project with capacity to generate 500 MW. (construction.com)
