The Blue Concept is a major retail network modernization project of INA petrol stations that started at the end of 2010. More than sixty petrol stations have been modernized in all of INA’s four regions: Osijek, Zagreb, Rijeka and Split. Before this year's tourist season, the Blue Concept was primarily focused on the petrol stations along the Adriatic (Rijeka and Spit), which now provide top service to local and international tourists and meet the increased demands for our products and services during the summer. In July modernization of continental petrol stations commenced. In Osijek region 4 stations are modernized. In Zagreb region works at the Zagreb-Zagreb Avenue-South petrol station have already started, while Čakovec-Zrinski-Frankopan and Mursko Središće will follow next. By the end of this year, all regions will have 100 modernized stations in total.
