1. Surge tanks on each headrace tunnel help prevent water hammer. 2. Feeding water to the penstocks is a long headrace tunnel with a three gate intake structure. 3. The dam diverts water east into three long and diameter headrace tunnels towards the actual power station. 4. Each headrace tunnel connects to a steel-lined penstock, each of which later bifurcates into two penstocks. 5. In mid-2008, the Keldu�rst�fla and Ufsarst�fla Dams were complete and the Ufsarl�n pond headrace tunnel was ready. 6. A long headrace tunnel connects the reservoir to the power station which contains three 48 MW Francis turbine-generators. 7. Water from an intake on the saddle dam travels through a headrace tunnel to the power station which is located underground. 8. Water from the Ufsarl�n pond is diverted down a long, diameter headrace tunnel where it joins the H�lsl�n reservoir headrace tunnel. 9. Water from the Ufsarl�n pond is diverted down a long, diameter headrace tunnel where it joins the H�lsl�n reservoir headrace tunnel . 10. Connecting the upper reservoir and the power plant will first be two headrace tunnels , one long and the other in length.
