With Búrfell Power Station II, the generation output increases by up to 300 GWh per year. This is due to improved utilization of flow to Búrfell Power Station and a decreased efficiency losses, when the load is transferred. The new power station was built underground in the Samsstaðaklif Hill and houses one 100 MW Francis turbine. The 370 m long headrace canal is connected to the existing intake reservoir Bjarnalón and the 2,200 m long tailrace canal discharges the harnessed water into the Fossá River, approx. 1 km downstream from the original Búrfell Station. The harnessed water travels between the headrace and tailrace canals through a 110 m long pressure shaft which connects to the turbine.
