All the crude oil refined at Mongstad comes from the North Sea. The largest production is petrol, diesel, jet fuel, and light petroleum products. The heaviest components are used to make petrol coke, an important ingredient in anodes for aluminum production.
In 2010, Statoil and DONG Energy opened the Mongstad Power Station, a natural gas-fired thermal power plant, to provide the site with heat energy and electricity, as well as power to the Troll gas field.
