For AggregateEU Participants

AggregateEU is our solution for demand aggregation and collaborative gas tendering within the EU Energy Platform. In 2023, reliable suppliers successfully matched a combined volume of 42.13 billion cubic meters of aggregated European gas demand across four rounds.

AggregateEU: A Success Story

In April 2023, the EU Energy Platform launched the first tendering round via AggregateEU. By leveraging its collective economic weight, the EU managed to attract bids from a total number of 25 supplying companies equivalent to more than 13.4 billion cubic meters of gas (bcm) – surpassing the 11.6 bcm of joint demand that EU companies submitted through PRISMA's AggregateEU mechanism.

PRISMA matched the international suppliers with the European customers, amounting to an overall volume of 10.9 bcm. This covers 8.7 bcm of gas via pipeline and 2.2 bcm of LNG.

Afterwards, EU companies were able to negotiate the terms of the supply contracts directly with the supplying companies, with no involvement of the Commission. 

Vice-President Maroš Šefčovič said: "The EU Energy Platform has had a remarkable success despite being very new. It clearly shows the need for such a market place, leveraging the EU's collective economic weight to increase our energy security and tackle high gas prices. The Commission has played its role as aggregator and matchmaker, and now it is for the respective parties to conclude their agreements. It is a win-win for European customers and for international suppliers." Watch the press briefing.

This exercise supported the EU countries' efforts to meet their gas storage obligations for the winter while strengthening the collective energy security at competitive prices. Further tenders followed every two months until the end of the year.

In December 2023, the European Union established the legal framework allowing PRISMA to operate AggregateEU for another year. You can read the full success story here.

The Mid-Term Tender

In 2024, PRISMA and the EU Commission introduced the Mid-Term Tenders to address the growing demand for stability and predictability among participants.

Purpose of Mid-Term Tenders

-  Mid-Term Tenders enable industrial consumers to explore additional trading options under a pseudonym, attracting buyers purely based on demand profiles.
- These tenders help sellers identify buyers interested in longer trading partnerships, potentially lasting up to five years.

About Mid-Term Tenders via AggregateEU

Mid-Term Tenders allow participants to submit demands for six-month periods: Summer (April 1st to September 30th) and Winter (October 1st to March 31st). The earliest delivery is anticipated for Summer 2024, with the last delivery in Summer 2029.

Buyers can submit their demands for up to five years, or ten consecutive six-month periods, with each demand meeting the minimum stipulated quantity for the relevant product: LNG (1,800,000 MWh) or NBP (30,000 MWh).

Each demand at a specific location for a particular period will be published as a separate tender, allowing sellers to express their interest in selling to individual buyers based on the total demand. To ensure fairness, buyers will be displayed to sellers under a pseudonym.


The first Mid-Term Tender on AggregateEU occurred in February 2024. Maroš Šefčovič, Vice-President of the European Commission stated: "Altogether, 19 companies – including industrial consumers – have submitted requests for a total volume of almost 34 billion cubic metres of gas. LNG demand represents over 15.3 bcm, while more than 18.3 bcm is requested for delivery via pipeline. This clearly shows that the joint purchase of gas is going from strength to strength."
