GEOTHERMAL ENERGY IN SUDAN
ELECTRICITY SUPPLY INDUSTRY
STRUCTURE IN SUDAN
In 2010 new structure has been established by splitting the
National Electricity Corporation to the 5 companies as follow:-
1. Merowe Dam Electricity Company Ltd.
2. Sudanese Hydropower Generation Company Ltd.
3. Sudanese Thermal Power Generation Company Ltd.
4. Sudanese Transmission Lines Company Ltd.
5. Sudanese Electricity Distribution Company Ltd.
All 5 companies together with regulation authority under the
supervision of Ministry of Electricity & Dams

GEOTHERMAL PREVIOUS STUDIES
No systemic exploration of geothermal resources has been carried in
Sudan. Robertson Research International Limited carried review of
potential geothermal areas in 1987.
Evan & Tammemagi summarized the results of temperature
gradient & heat flow studies for wells drilled in Red Sea coast
1974.
temperature gradient & heat flow studies of oil wells in central Sudan
Rift system carried out for GRAS 1980.
National Energy Administration – USA reviewed temperature data of
Red Sea oil wells and proposed the development geothermal energy
filed near shore exploratory oil wells
AREAS WITH GEOTHERMAL ENERGY
POTENTIAL
Tertiary to recent age volcanic fields in west, central and
eastern areas of country.
The coastal plain adjacent to the Red Sea Rift zone.
The central Sudan Rift zones
GEOTHERMAL POTENTIAL OF VOLCANIC
AREAS
Jebel Marra Area:
a. covered area of 140km by 50 km.
b. Many hot springs with the temperature between 65 -85 ⁰C.
c. Existing Fumaroles emit hot gases under pressure.
d. Negative Gravity Anomaly – 1000 km wide, 50 Mgal
amplitude.
e. It is planned to be connected to the national grid in 2013.
Tagbo & Meidob Hills:
a. No reports of surface thermal manifestations
b. Eastern side of the negative gravity anomaly.
GEOTHERMAL POTENTIAL OF
VOLCANIC AREAS
Bayuda Volcanic field:
a. It covers an area of about 520 km².
b. Contains over 100 small recent scoria cones &
associated basaltic lavas.
c. A number of volcanic centers consist of
explosive craters.
d. No surface manifestation.
e. Presence of small saline lake.
f. North eastern limit of the gravity anomaly from
Jebel Marra.
g. Already connected with national grid.
GEOTHERMAL POTENTIAL OF THE
CENTRAL SUDAN RIFT ZONES
Central Sudan Rift Zones:
a. Extensive oil exploration has been carried out since the
last reviewed in 1991.
b. No reported surface manifestations.
c. Earthquakes and heat flow anomalies have been
reported 50 km south of khartoum.
d. Some tertiary and quaternary lavas are present in the
region.
e. Robertson Research International ( 1987) found the
temperature gradient range between 20 ⁰C/km and 30
⁰C/km- but theoretically are attractive for future studies.
GEOTHERMAL POTENTIAL OF THE RED SEA
COASTAL PLAIN
Red Sea Coastal Plain:
a. More than 25 wells exploration has been drilled
in the area.
b. High temperature toward the sea bed, low
temperature in mainland.
c. Durwara-2 well encountered bottom hole
temperature of up to 193 ⁰C and temperature
gradient of 40 ⁰C/km.
d. 3 wells drilled on cost have high heat flow value
about 100 mWm¯²
GEOTHERMAL POTENTIAL OF THE RED SEA
COASTAL PLAIN
AREAS WITH HIGH PRIORITY FOR INVESTIGATION
The Suakin area on Red Sea coast.
The volcanic field in the Bayuda Desert.
The Jebel Marra volcanic complex and adjacent areas.
FUTURE PLAN
Kengen will conduct detailed geo-scentific survey in prospect
areas as follow:-
a. Geological mapping .
b. Hydro-geological data interpretation.
c. Geochemical investigations.
c. Geophysical investigations
c. Environmental baseline study
d. a conceptual model for further work.
Capacity building in related fields
WHAT WE NEED
a. Capacity building .
b. Legal framework.
c. Further study.
c. Finance and technical support for further study
