Can any body tell me which project is this? I know it is not koysha dam since the coordinate for koysha is a different one & i know that the construction started in year 2017. This google earth image was taken on december 22, 2013. Here are the coordinates for your reference: 6°18'26.44"N 36° 3'26.52"E

I believe it is Kuraz 1 Sugar Mill

It seems the Corbetti geothermal project has been cut down dramatically, but at least is still going on. I remember reading it had 2 phases, each with 500MW capacity. It's now dropped to a total of 150MW it seems like.

Corbetti Geothermal signs new PPA and Implementing agreement for project in Ethiopia

The developer of the Corbetti geothermal project in Ethiopia has also signed a new PPA and Implementation Agreement with the government of Ethiopia and the state-owned power utility in the same ceremony for another project.

Following news earlier today, we since learned that besides an agreement for the Tulu Moye geothermal project, Corbetti Geothermal and its sponsors – InfraCo Africa (a PIDG company), Berkeley Energy who manage the Africa Renewable Energy Fund, Iceland Drilling and Reykjavik Geothermal – have also signed a new Power Purchase Agreement (PPA) and Implementation Agreement (IA) with the Government of Ethiopia (GoE) and Ethiopian Electric Power (EEP). The signings mark the next step for the pioneering geothermal project.
“Corbetti Geothermal is extremely pleased to be participating in this signing ceremony. The signing of the PPA and IA today allows us to move forwards in partnership with EEP and the Government of Ethiopia in order to realise this important project for the benefit of the people of Ethiopia.” Helgi Leifsson, General Manager, Corbetti Geothermal.
Over the past decade, Corbetti and its sponsors have remained committed to the project and to developing Ethiopia’s geothermal potential. The PPA and IA signed today will allow the project to move into the next phase of implementation, and to commence the drilling programme.
InfraCo Africa’s CEO, Gilles Vaes, said: “We remain committed to developing geothermal power in Ethiopia during these challenging times and are excited to be taking the next steps together and in close partnership with EEP and the Government of Ethiopia, to realise this ambitious project.”
Corbetti Geothermal will be one of the first pair of privately developed, owned and operated geothermal IPPs in Ethiopia. The complex project has evolved over time to manage the early stage development risks and costs associated with being a pioneer. Corbetti will be developed in two phases over a five year period. The first phase will drill four to six exploratory wells , with support from the Geothermal Risk Mitigation Facility, to raise debt finance to drill a further four to seven wells and build a 50MW power plant, which is expected to become operational in 2023. The second phase will consist of an additional 100MW power plant and facilities. Whilst the overall size of the project has been reduced; totalling 150MW, the full Corbetti programme will enable the GoE to meet 18% of its 2025 geothermal generation target.

This is largely due to how geothermal exploration works. Depending on the energy potential of each well 5-10 wells can feed one 50 MW-turbine. Depending on the depth one rig takes about 40-70 days to drill one well. A 50 MW geothermal power plant doesn't really cost much more per MW as a 500 MW geothermal power plant as the cost of drilling wells doesn't scale. The advantage here is that while working continuously two to three drilling rigs can drill enough wells for a 50 MW power plant every year.

Another important thing to remember is that 50 MW of geothermal installed capacity generates as much electricity as 150 MW of hydro.
