The Kindaruma power station ( English Kindaruma power station ) is a run-of-river power station on the border between the counties Embu and Machakos in Kenya . It is located on the longest river in Kenya, the Tana .

The power plant was commissioned in 1968. It is owned by the Kenya Electricity Generating Company (KenGen) but is operated by the Tana River Development Authority (TARDA). Kindaruma was the first major hydropower plant built after Kenya gained independence.

Barrier structure

The barrier structure consists of a stone and earth embankment dam with a height of 24 m. The length of the dam crest is 549 m. The dam has a flood relief with three gates.

Reservoir

When the reservoir is fully blocked, it extends over an area of ​​around 2.4 km² and holds 16 million m³ of water.

power plant

With an installed capacity of 72  MW, the Kindaruma power plant is one of the medium-sized hydropower plants in Kenya . The average annual production fluctuates with the water flow of the Tana: it was 157 million kWh in 2008 and 241 million kWh in 2007.

Since July 2013 three Kaplan turbines with an output of 24 MW each have been in operation. The associated generators each provide 28.2 MVA. The rated speed of the turbines is 214.3 / min. The generators have a nominal voltage of 11  kV . In the switchgear , the generator voltage is increased from 11 kV to 132 kV using power transformers.

The maximum height of fall is 36 (or 32) m.

expansion

The first two Kaplan turbines were put into operation in 1968 (with an output of 20 MW each at the time). When the power plant was built, provisions were made for the installation of a third machine; however, due to the lack of electricity demand at the time, this was not done.

In January 2010, KenGen commissioned Andritz AG to install a third machine with an output of 24 MW and to increase the output of the first two turbines to 24 MW each. The additional machine went online in June 2012; the rest of the work was then completed by July 2013. The expansion was partly financed by KfW . The order value was originally KES 3.93 billion . The total costs after completion of the work are however 4.6 (or 5.4 or 6.3) billion KES.

Others

The power plant is part of a chain of five hydropower plants on the Tana - Masinga , Kamburu , Guitaru , Kindaruma and Kiambere - which together have an installed capacity of 567 MW. In the 1970s, feasibility studies were carried out for the expansion of hydropower on the Tana, which envisaged a cascade of eleven power plants. But so far only the above five have been implemented.
