EuroPEX POSITION REGARDING TRANSPARECNCY ON THE EUROPEAN ELECTRICITY MARKETS  EuroPEX shares ERGEG’s vision that a correct management of the information and an adequate level of transparency improve the development of liquid, transparent and competitive electricity markets.  ERGEG has accepted most of the EuroPEX comments made during the public consultation phase. ●When information is to be disclosed, it should be published, rather than being made available on request. ●The minimum set of information which is made available in a Member State or control area should not depend on the structure of its electricity sector, but should be made available according to the same minimum standards of detail in all Member States. ●The ex-ante information published should be compiled on the basis of objective criteria. The ex-post real values should also be published. ●The information relative to technical standards or constraints should be accompanied by the disclosure and transparency of the methodologies used to define them ●Effective information “firewalls” on vertically integrated utilities. ●Clear distinction between the roles of the information source and the information publisher. ●Similar transparency requirements should be applied to OTC transactions. ●The responsibility for disclosing information on electricity trading should rest, in the first instance, with the trading parties. ●The aggregated supply and demand curves, prices and volumes of the spot and intraday markets apply to auction based markets, for intraday continuous trading markets other requirements should apply. ●Prices and volumes information transparency on the OTC markets should be applied at the individual transaction level rather than aggregated for some products.
