Implementation agreements and 25-year power purchase agreements (PPAs) were signed on 19 December by project companies, the Ethiopian government and Ethiopian Electric Power (EEP) for the Corbetti and Tulu Moye geothermal plants in Oromia. Both multi-phase projects are 520MW and are expected to cost around $2.2bn to develop. The agreements are expected to be taken to parliament for ratification early next year and drilling is expected on the first production wells at Corbetti in 2018.
