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.

About 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.
Why it mattered
With AggregateEU, we created a new opportunity to procure gas in addition to existing marketplaces or practices. It brought additional value to market participants through demand aggregation, increased transparency, and new forms of cooperation. This was particularly beneficial for—though not limited to—smaller companies or those in landlocked countries, as they benefited from demand aggregation due to the size of their demand or their limited experience in contracting LNG.
Furthermore, AggregateEU enabled demand aggregation by individual companies or by groups of companies through the establishment of cooperation models such as central buyers and agents acting on their behalf.
How it worked
AggregateEU organised tendering rounds every two months. Participating in an AggregateEU tendering round (i.e. per month, per location) involved four steps:
- Demand aggregation and tendering
- Matching between buyers and sellers
- Contracting (outside the platform)
- Procurement transparency
Who did participate
On the demand side, companies established in the EU or in the Energy Community countries took 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 were able to participate.
