For AggregateEU Participants
AggregateEU is our solution for demand aggregation and collaborative gas tendering within the EU Energy Platform. Subscribed users can currently participate in the 4th round. In October 2023, we successfully concluded round 3 through AggregateEU. Explore the outcomes below.

The Overall Timeline of Tendering Round 4

On November 23, we started with phase one of the fourth tendering round: The Demand Collection. Participants are able to submit demand for the months of January 2023 until and including March 2025. Based on this, AggregateEU will aggregate the submitted demand. Participants can then evaluate whether they want to proceed to the tendering and matching phases or decline to do so.
After closing the Demand Collection, AggregateEU will use the confirmed, aggregated demand to create and publish tenders for sellers to bid on and subsequently match the demand to their offers. In light of the matching results, participants can negotiate and conclude contracts outside AggregateEU to acquire gas for specific locations and months. Finally, buyers are required to report contracts that have been concluded or that are in negotiation back to AggregateEU.

More than another Trading Hub
AggregateEU has been developed for the EU Energy Platform, which aims to pool the gas demand in Europe to secure the energy supply. AggregateEU is a mechanism designed to match buyers and sellers of natural gas and LNG via the PRISMA platform while ensuring equal treatment and preventing market manipulation.
With AggregateEU we created a new opportunity to procure gas in addition to existing marketplaces or practices. It brings additional value to the market participants with demand aggregation, increased transparency and new forms of cooperation. This brings particular benefit for, but is not limited to, smaller companies or those in landlocked countries, from demand aggregation – given the size of their demand or their lack of experience in contracting LNG.
Further, AggregateEU enables demand aggregation by individual companies or by groups of companies via the establishment of cooperation models such as central buyers and agents on behalf.
AggregateEU organises tendering rounds every two months. Participating in an AggregateEU tendering round (i.e. per month, per location) will involve four steps:
- Demand aggregation and tendering
- Matching between buyers and sellers
- Contracting (outside the platform)
- Procurement transparency
On the demand side, companies established in the EU or in the Energy Community countries can take part in demand aggregation and joint purchasing of gas, either alone or through a central buyer.
On the seller's side, both EU and non-EU companies will be able to participate.
Companies will have to follow a two-step process to participate in AggregateEU. First, they will need to register with PRISMA. Second, they will need to subscribe to AggregateEU. We explain both processes in detail in the linked articles in our AggregateEU Hub. In it, we also explain all phases of a tendering process in detail and all the requirements for participating in AggregateEU.
If you have any further questions, you can find an extensive list of questions and answers on the EU Commission's website.

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.
