The Kárahnjukar Hydroelectric Project is located in eastern Iceland on the Jökulsá rivers. The water is dammed to form the Hálslón Reservoir (2,100 Mm3) and then conveyed by a 40 km long headrace tunnel to the Teigsbjarg escarpment, where it is fed via two 4.04 m diameter steel lined vertical pressure shafts, 420 m high, to the underground powerhouse.
