Masinga Hydroelectric Power Station, also Masinga Dam, is an embankment dam on the Tana River, the longest river in Kenya. It straddles the border of Embu and Machakos Counties in Eastern Province and is located about 100 km northeast of Nairobi.
The Masinga Dam is located approximately 2.5 hours from Nairobi and 1 hour from Kitui town. The road to the dam is generally good except the last 12 kms which lead to the dam. Reception is good and the people are courteous and very polite.
Feasibility studies were made in the 1970s and they confirmed the viability of a cascade of hydroelectric power plants along the Tana River: Masinga, Kamburu, Gitaru, Kindaruma, Kiambere, Karura, Mutonga, Low grand Falls, Usheni, Adamsons Falls, and Kora. Only the first five of them have been built so far.
