text: The state is down to three commercial refineries after Flint Hills’ North Pole refinery ceased operations in 2014: Petro Star’s refineries in Fairbanks and Valdez and Tesoro’s refinery in Nikiski. Petro Star mostly produces jet fuel while the Tesoro refinery mostly produces gasoline and exports the remaining heavy oil to other markets.
