With no domestic refining capacity, Slovenia is entirely dependent on oil product imports to satisfy demand. The fuels marketing sector is dominated by Petrol d.d. and OMV, and government price controls have kept fuel margins well below the European average. Fuel price regulation has started being relaxed on certain grades and distribution channels from 2016. In the past, price regulation has acted as a barrier to new market entrants, also limiting the attraction of investment in fuel storage and distribution infrastructure. Low historic fuel margins provided incentive for fuel retailers to develop the non-fuel revenue segments at their service stations, such as convenience stores. In 2015, MOL acquired Eni's downstream business in Slovenia, including its fuel retail network and wholesale business.
