Africa’s geothermal future depends on one crucial step, exploration. Before any power plant is built, these teams are out in the fields mapping reservoirs, drilling test wells, and proving the steam the continent will one day run on. Their work forms the bedrock of Africa’s geothermal ambition, especially across the Rift Valley where some of the world’s strongest geothermal potential lies.
Here are the Top 5 Geothermal Exploration Companies in Africa as of 2025 (based on verified exploration activity, multi-year drilling involvement, and documented regional operations):
— Geothermal Development Company GDC (Kenya): Leads Kenya’s geothermal exploration through drilling, reservoir testing, and steam field development, with active work in Menengai, Baringo–Silali, Suswa, and more.
— KenGen (Kenya): Beyond power generation, KenGen provides exploration drilling services across Africa, supporting geothermal development in Tanzania, Zambia, Ethiopia, and Djibouti.
— Kalahari GeoEnergy (Zambia): A private geothermal exploration company advancing the Kafue Trough resource, with multiple gradient wells drilled and new reconnaissance licenses in Malawi.
— Akiira Geothermal Limited (Kenya): A focused private explorer progressing the Akiira geothermal prospect, backed by regional grants and early-stage drilling preparations.
— Reykjavik Geothermal / Tulu Moye JV (Ethiopia): A globally recognised geothermal explorer providing subsurface assessment and early-stage development support for Ethiopia’s Rift Valley fields.
Activity across the geothermal space is increasing, but these five stand out for their documented exploration efforts and their role in shaping Africa’s long-term geothermal development.
