The National Natural Gas System Operator (DESFA) S.A. was founded on 30 March 2007, following the provisions of law 3428/2005 (Government Gazette 313/27.12.2005) on liberalization of the natural gas market, which aligned Greek laws with the European Directive 03/55/ EK. This law established DESFA S.A. as a subsidiary company owned in its entirety by DEPA S.A. DESFA is responsible for the operation, management, exploitation and development of the National Natural Gas System and its interconnections, in a technically sound and economically efficient way, in order to best serve its Users with safety, reliability and adequacy.
Contributing decisively to the security of supply and the diversification of supply sources of the wider region, DESFA also facilitates the development of competition in the Greek energy market, while systematically striving for the reduction of greenhouse gas emissions.
Possessing extensive experience and having a highly skilled staff, DESFA is a reliable partner in the framework of the ongoing international energy projects in Southeastern Europe.
