Aluto Langano

The Aluto Langano Geothermal 9MW Power Plant was the first geothermal power plant in Ethiopia. It was established in 1998 as a pilot plant to test the geothermal resources and to identify any resources or issues that could affect future power plant development as well as to provide much-needed power to the national grid.

Located about 200km south of Addis Ababa in the Rift Valley Lakes Region 15km northwest of the Adami Tulu Substation and the 132kv transmission line at Hawassa road. The geothermal resource covers an area of about 8km2 in an area located at an elevation between 1880 and 2100 meters. With an anticipated resource of 300MW the Aliuto Langao facility is a key aspect of Ethiopia future power profile.

CSI was extremely honoured to complete such a groundbreaking project providing much-needed energy to support development and basic social welfare. Working in partnership with Ormat Technologies (Israel) this project was CSI’s first venture outside of Tanzania’s border. This plant facilitated the first use of natural resources in Ethiopia and consisted of two Ormat generating units, one an OEC (Ormat EnergyConverter) and the other a GCCU (Geothermal Combined Cycle Unit) consisting of a backpressure steam turbine exhausting to an OEC bottoming cycle unit) – each designed to have similar power outputs.

CSI carried out the entire installation of all mechanical plant, steam pipework, fire fighting pipework and pumping systems.
