Teško da bi iko u Bugarskoj pod znak pitanja stavljao potrebu za diverzifikacijom energetskih izvora i pravaca opskrbe, posebno nakon gasne krize u januaru 2009, kad je spor oko cijena između Rusije i Ukrajine doveo do ozbiljnog prekida u isporuci za veliki dio Evrope.
Hardly anyone in Bulgaria would question the need for diversifying energy sources and supply routes, particularly following the gas crisis in January 2009, when a price row between Russia and Ukraine led to a severe disruption in deliveries to much of Europe.
