John Magiro 

Technical Director

John grew up in a small village in Murang’a Kenya, about 3 hours drive from the capital Nairobi. Growing up, no one in his community had electricity. The nearest electricity pole was 15 km away.


After seeing his mother struggle, he decided to build his first micro hydro power plant using everyday objects. His talent was quickly noticed, allowing him to scale up and professionalize the technology, constructing a dam that channels water to a turbine and generates electricity. Today, John operates a hydro power plant providing affordable electricity to over 250 households and through his involvement in Hydrobox, plans to build many more.


John is the winner of the Switch Africa Green – Seed Award 2016, the East Africa Hub Grant 2017 and the WWF Africa Youth Awards 2017
