During the 1st EnDev East Africa Micro Hydro Workshop which was held in 2009 a field visit was done to see the Greenpower Project Kirangurwe near Mount Kenya.
The field trip was accompanied by serval Micro Hydro Experts. There impressions of the project site and setup were share in a expert panel discussion. Here is a summary of their statements:
