Since Alarko aimed to be engaged in energy trade (buying and selling) in addition to power generation, a supply license was obtained in April 2014 from EMRA for Alen Alarko Enerji Ticaret A.Ş. A Market Participation Agreement was signed with TEİAŞ for Alen and an application was filed for registration in the Capacity Auction Tool (TCAT) for cross-border trade with Bulgaria. Alarko Energy Group has a flexible system that has been designed to match with the dynamic structure of the energy trade market.
