The Vatnsfell power station ( isl. Vatnsfellsvirkjun or Vatnsfellsstöð = Vatnsfell station ) is a hydroelectric power station in the Icelandic highlands near the Sprengisandur route.
Vatnsfellsstöð is a peak load power plant that is mainly in operation in winter, when electricity needs are highest in Iceland. It was built between 1999 and 2001 by the Icelandic electricity company Landsvirkjun . The German company Lahmeyer International was also involved in the planning .
Structure and technology
The power plant uses the difference in altitude between the two reservoirs Þórisvatn ( height above sea level 577 m) and Krókslón (height 498 m), which are connected by a canal. This canal was in turn dammed by a 750 m long dam to a small reservoir Vatnsfellslón (height 563 m, area 0.6 km², storage volume 3.2 Gl).
From the inlet, the water flows through two 126 m long tubes with a diameter of 4.5 m and a 67 m gradient to two Francis turbines from GE Hydro , each with 45 MW electrical power . The expansion water volume is 160 m³ / s; the annual average flow is around half of this value.
The canal is again used as underwater and flows into Lake Krókslón after 2.4 km.
The Vatnsfell power plant is connected to the Sigalda power plant on Lake Krókslón via a 220 kV high-voltage line.
Works of art at the power plant
Two works of art were installed at the foot of the power plant between 2003 and 2005:
- The Icelandic artist group Gjörningaklúbbinn (Icelandic Love Corporation) created the work of art Mother Earth (Móðir jörð) . It consists of a triangular piece of earth that stands out from the bare surroundings through its vegetation. The borders are illuminated with the energy of the power plant, so that an impressive picture emerges, especially at dusk (see left).
- The Icelandic artist Finnbogi Pétursson created a square, walk-in sound tube called Tíðni (frequency) , which emits a humming tone of 50 Hz according to the mains frequency of the power plant.
