TMGO steps up drilling operations at Ethiopia’s flagship geothermal project


Tulu Moye Geothermal Operations (TMGO) has announced the spudding of the GD1 well by Marriott Drilling at its Tulu Moye geothermal project in Ethiopia. Marriott Drilling is the second drilling contractor mobilized on site along with the Kenya Electricity Generating Company (KenGen).

TMGO is a joint venture of Meridiam (51%) and Reykjavik Geothermal (49%) that is developing Ethiopia’s first Independent Power Producer (IPP) project. The Tulu Moye geothermal facilities are expected to be set up on one of the best geothermal fields in the world, with an estimated capacity of over 1 GW.

Phase 1 is targeting 50 MW by December 2024 and by 150 MW by 2025 under an $800m investment programme, before eventually ramping up to 520 MW.

KenGen started drilling for phase 1 in March 2020 but had to suspend operations for several months due to travel restrictions imposed by the Covid-19 pandemic. Drilling activities were able to resume only in mid-June 2020 and the first well, GA1, was completed in early 2021. GA2 and GA3 were eventually drilled throughout 2021 followed by GB1 in early 2022.

Details on the Tulu Moye Geothermal Project in Ethiopia are available in the “Projects” section within your Hawilti+ research terminal.
