A major storage site for Slovenia's strategic petroleum reserves is located in a valley immediately west of Ortnek. In the past, it was used as a military petroleum reserve. The Ortnek facility is one of Slovenia's largest petroleum storage sites, the total stockpiles of which are envisaged as sufficient to supply Slovenia's needs for three months. Diesel fuel and gasoline are stored at the site, as well as kerosene at times. In addition to the visible reservoirs, there are seven underground reservoirs built into the surrounding hills. Access to the site is strictly controlled.
