ACER, Europe’s Agency for the Cooperation of Energy Regulators, has questioned, if not rejected, Greek gas grid operator DESFA’s proposed formula for calculating gas network charges, needed as an adjustment to the European Commission’s new TAR, or regulation establishing a network code on harmonized transmission tariff structures for gas.

ACER recently offered its view on the DESFA proposal through a consultation procedure staged by RAE, Greece’s Regulatory Authority for Energy.

The DESFA proposal includes a basic charge as an addition to revenues recovered from main transmission system charges as well as a Revythoussa LNG terminal entry-point discount for fairer market conditions.

RAE needs to reach a decision by May 31 on new network usage tariffs to apply as of January 1, 2020.
