Revithoussa: PPC wants LNG unloading slots of at least 1 TWh, DEPA seeks more flexible auctions

Greece's Regulatory Authority for Energy, Waste and Water (RAAEY) on 4 November published the list of participants and the letters submitted to its consultation on the parameters of the annual LNG planning for 2027–2041, proposed by gas system operator DESFA for the Revithoussa terminal. Responses came from DEPA Trading, with two letters, power company PPC and a third participant that asked for confidentiality.

What PPC wants. The company proposes that, from 2041, the 500 GWh unloading slots be abolished and the LNG quantity per available slot be set at no less than 1 TWh, according to Energypress and iEnergeia. PPC points out that modern LNG carriers hold 170,000–180,000 m³, roughly 1.1–1.2 TWh, and that smaller slots can lead to partial unloading and extra transport and supply costs. Larger slots would raise terminal utilisation and lower unit tariffs, the company argues.

DEPA's position. DEPA Trading questions whether credible planning is possible over a 15-year horizon amid geopolitical uncertainty. The company has opposed extending planning from 5 to 15 years since 2023 and argues that the winter 2025–2026 auctions showed the current rules do not allow extraordinary events such as wars or pandemics to be factored in, leading to high prices that consumers ultimately pay. DEPA wants auctions of differentiated duration, as European rules allow, and the auctions for the years 2036, 2040 and 2041 to be postponed to 2027.

Context. The first consultation was launched on 4 August 2026; after comments, DESFA submitted an updated proposal, put to a supplementary consultation on 14 October, according to RAAEY. Both companies aim, through their proposals, to cut gas supply costs.

What comes next. The final planning parameters remain to be set following the consultation.
