| 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.
