DSD NOELL GmbH signs contract for "Búrfell Extension HEP" / Iceland

In March 2016, the Icelandic energy group Landsvirkjun awarded DSD NOELL GmbH with a contract for the construction of the gates and penstock of "Búrfell Extension HEP", which is located around 100 km east of the capital Reykjavik.

The construction of "Búrfell Extension HEP" was commenced in spring 2016, commissioning is scheduled for late April 2018.
As the existing 270 MW power station, the new power station will be operated by water from Bjarnalon reservoir and have a capacity of 100 MW, generated by one single turbine.

Each year, "Búrfell Extension HEP" will feed about 300 GWh into the grid and hence improve both supply reliability and grid flexibility.
