The Agency for the Cooperation of Energy Regulators (ACER) commissioned CEPA to conduct an in-depth review of electricity transmission tariff structures across the EU.

Activities involved (1) developing an assessment criteria for classifying and analysing current transmission tariff practices; (2) classifying and analysing the current electricity transmission network tariff practice(s) in every EU member state to assess the extent to which a lack of tariff harmonisation impedes market integration, effective competition, efficient functioning of the market, and any other relevant aspects identified (e.g. adequate investment levels); (3) identifying and developing proportionate policy options to address any actual or potential overarching problems and failures, including the assessment of the costs and benefits of each option; and (4) contributing to the drafting of the ACER’s scoping paper on tariff harmonisation.

As part of the assignment, CEPA ran a survey of industry participants across Europe to collect views and evidence on the impact of current transmission tariff structures on the efficient functioning of the EU internal electricity market and potential policy options for harmonisation.  The survey was followed up by stakeholder interviews and two workshops organised by ACER where CEPA presented and discussed findings with a wide range of stakeholders.
