The Greek Fertilizers Company (1/5) ELFE (formerly Phosphoric Fertilizers Industry) established in 1961 Initially, the final products were compound NPK fertilizers for domestic use. Over the next decades, the existing plants were substantially upgraded or replaced by new ones, while new plants were added. HELLENIC FERTILIZERS AND CHEMICALS ELFE S. A. 4 Dr. Th. Kouloura

H. A. C. I. “Energy Efficiency Management in Chemical Industry Sector”, Thessaloniki 2 nd of June 2014 ELFE: Legislative difficulties in energy saving 1. Excise Duty in NG used as Raw Material (must be excluded according to EC Directive) 2. Extremely high comparative price of NG (above the mean value in Europe) 3. Excise Duty, RES and taxes applied to the own produced electricity (provision for exclusion according to EC Directive) 4. High comparative price of electricity from the grid 5. Absence of State Aid for CO 2 cost from indirect emissions (Norway, UK, France, Belgium, Germany etc. have already proceed on) HELLENIC FERTILIZERS AND CHEMICALS ELFE S. A. 19 Dr. Th. Kouloura

H. A. C. I. “Energy Efficiency Management in Chemical Industry Sector”, Thessaloniki 2 nd of June 2014 Conclusions A. HELLENIC FERTILIZERS AND CHEMICALS ELFE S. A. is the last Greek fertilisers producer which - investes in energy saving since the beggining of its operation - applies the Best Available Techniques in energy saving B. Although ELFE achieves very attractive energy performance indicators, the company suffers from Excise Duties, RES and Taxes in energy due to the governmental legislation C. The European countries recognising the importance of energy adopted the principles of a common policy for NG and electricity and applied measures for supporting the industrial sector. Relatively masures have to be adopted by the Greek government in the framework of European competition rules. HELLENIC FERTILIZERS AND CHEMICALS ELFE S. A. 20 Dr. Th. Kouloura
