The European Commission has authorised Slovenian tariffs for “green” electricity subject to changes in the financing mechanism. Slovenian network operators have the obligation to purchase electricity produced from renewable energy sources and efficient combined heat and power plants at a price above the market price fixed by the State. The aid thus provided by Slovenia does not exceed the difference between the market price and the production cost for this type of electricity and is in line with EU environmental aid guidelines. However, as part of the scheme, consumers had to pay an additional parafiscal levy on their electricity consumption. According to the Commission this could have led to discrimination against imported “green” electricity. Slovenia has therefore undertaken to finance the scheme through a lump sum based on connection power.
