The Hauna scheme is a 2.3MW scheme taking water from the Ngarura river which is a tributary of the Honde river. It was built from May- December 2016 and commissioned in January 2017 with the onset of the rains.
The scheme has a head of 116m and is designed to pipe up to a maximum of 2.5 cumecs of flow. The 2.3MW generator has an operating range of 8%-100% of the available river flow, which enables operation for 10 months of the year.
From the offtake weir, the water is piped in a steel penstock for 4,300m to the powerhouse which is located close to Hauna town. The electricity is transmitted into the 33KV national grid at Hauna.
