From 2007 until today, all electricity consumers enjoy the right to freely choose the Electricity Supplier that they prefer but also to negotiate the prices and the Conditions of Supply of the energy they need. The liberalization of the Electricity Market has resulted, through competition, in benefits for the final consumer in terms of cost reduction combined with the provision of a high level of communication and service.


The electricity bill for all Suppliers is divided into two main parts:

  • Competitive
  • Non-competitive

The Competitive strand refers to the Cost of Electricity Supply, specifically to the charges set by each Supplier for his Customer’s consumption.

The Non-competitive strand concerns charges that, although depending on the technical characteristics of the customer’s supply and consumption, are calculated on a fixed basis determined by the State. While the Supply Cost is negotiable between the Customer and his Supplier, the Non-Competitive Strand is an inelastic cost and is determined for each type of provision according to the same method of calculation by all Suppliers.
