ECA recently concluded a study entitled “Methodologies and parameters used to determine the allowed or target revenue of transmission system operators” for the Agency for the Cooperation of Energy Regulators (ACER). The objective of the study was to document and contrast the methodologies used by regulatory authorities across the EU in determining and setting the allowed or target revenues of gas transmission companies. The study entailed reviewing all key aspects of TSO revenue setting and the associated methodological approaches employed in the EU, and it provided an evaluation of the methodological approaches based on a conceptual framework developed for this purpose.
