Greek regulator approves 2025 gas tariff increases

Greek energy regulator RAEWW has approved 2025 gas transmission tariffs previously proposed by transmission system operator Desfa, with some alterations.

The annual tariff for entry to the Greek grid is set at roughly €0.35/MWh for 2025, around 4pc higher than in 2024 (see data & download). Exit tariffs at domestic and international points will be €0.59/MWh, a nearly 21pc increase on the year, while the LNG regasification tariff is set at €0.30/MWh, nearly 35pc higher than in 2024.

Before annual capacity auctions in July, Desfa had proposed some differentiation in entry and exit tariffs for different interconnection points, but RAEWW has instead opted for equalising entry and exit fees regardless of the point.

Multipliers for shorter-term capacities are set at around 1.38 for quarterly products, 1.48 for monthly products and 2.97 for daily products. These are the same multipliers which have been used for the past two years.

RAEWW set the allowed revenue for transmission services at €149.2mn. A much larger portion of the allowed revenue will come from exit points, at around €90.5mn compared with €58.7mn at entry points.

The regulator set an allowed revenue of €23.6mn for LNG services. It noted the Revithoussa LNG terminal has consistently exceeded its allowances since 2019, peaking at 312pc in 2023 as use of the terminal soared.

RAEWW has also opened a public consultation on proposed changes to the rulebook of Greece's Henex exchange, which would create a new "trading-only" type of participant.

The new category of participant does not need to be a registered user of the transmission system, but must have concluded a contract with exclusively one other participant who is registered, and guarantee that it will fulfil its obligations arising from any concluded trades.

If the registered system user loses its registered status, then the trading-only participant also does. Any termination of contract between the two parties must immediately be reported to Henex.

Interested parties can email responses to the consultation to RAEWW until 20 September.
