Hydroelectric Plants in Greenland

Buksefjorden
Location: Greenland
Operator: Nuuk Kraft ANS (BKK)
Configuration: 2 X 15 MW Francis
Operation: 1993
T/G supplier: Kvaerner, ABB
EPC: Norconsult, Niras Greeland
Quick facts: Greenland's first large hydro plant has an underground powerhouse, a concrete dam, lake tap intake, and a 12km headrace. The 56km transmission system includes two fjord crossings, one of which is the world's longest with a span of 5,375m. The project included 12km of access roads, permanent living quarters and workshops, a harbor, and a heliport. The plant is owned by Greenlandís power company Nukissiorfiit.

Paakitsoq
Location: Greenland
Operator: Nukissiorfiit Gronlands Energiforsyning
Configuration: 3 X 7.5-MW Francis
Operation: 2013
T/G supplier: Kossler, LDW
EPC: Verkis, Niras Greenland, TuCon as
Quick facts: This underground HPP harnesses the discharge from two natural glacial lakes in the Paakitsup Akuliarusersua area with storage obtained by drawdown of the water levels by respectively 30 and 50m from the present. The headrace tunnel is 1.3m long and the discharge tunnel is 1.8km long. The plant is connected to Ilulissat by a 50km, 60kV tie-line. Estimated annual production is 65 GW. Landsvirkjun has a 2yr O&M contract for the project. The photo shows the concrete service building at the powerhouse access tunnel, which runs 400m into the mountain. ABB supplied the switchgear and other electrial infrastructure.

  Sisimut
Location: Greenland
Operator: Nukissiorfiit Gronlands Energiforsyning
Configuration: 2 X 7.5 MW Francis
Operation: 2009
T/G supplier: Kossler, LDW
EPC: Verkis, Pihl & Søn, Istak
Quick facts: The town of Sisimiut is located 100km north of the Arctic Circle. The power station is located near the inner end of a long fjord 60km north harnesses the discharge from Lake Tasersuaq. Water is passed through an intake structure and then enters an evenly inclined unlined headrace tunnel to an underground powerhouse. The powerhouse is at sea level some 125m inside the mountain side and operates at an 80m head. Adjacent to the powerhouse is a cavern housing two main transformers, local transformer and switchgear. Water from the turbines empties into a tailrace tunnel which again opens into a tailrace canal leading to the sea. The site has no road access and the project was built under very demanding logistic and climatic conditions. Construction took about 3yrs. Output is expected to be 58 GWh/yr.
