Eress Partnership is a non-profit organisation, based on collaboration and innovation, committed to the integration of new partners, based on the same terms as the original partners. Fairness and balanced split of both investment and operational costs is one the principles underlying the partnership.



Will the accession to Eress partnership be subject to public procurement law for the new partner?

No, a new partner does not have to take into consideration the public procurement regulations when entering Eress partnership.

Eress has been set up to achieve the common goal of performing an optimal solution for settling train energy consumption on a non-profit basis. This is common for all Eress partners. To give you an example, if you want to be part of a boat club, you buy shares in the club and get access, plus the right to use the club. The same principle applies to Eress. The new entrant gets the same shares as the existing partners and access to Eress, plus the right to use Erex system. Therefore, the accession to Eress partnership is no subject to public procurement law.



Will Eress’ services rendered to the owners/partners be subject to public procurement law?

As long as Eress supplies services only to its partners / owners, and the services are part of the infrastructure managers' public services of maintaining an improving railway competitiveness and interoperability, the partners / owners may receive services from Eress, irrespective of public procurement law, provided that all partners have a vote in a steering committee or general assembly.

This question is linked to the notion of "in-house" services.

The EU Directives on public procurement (Public Sector Directive 2004/18/EC and Utilities Directive 2004/17/EC) do not apply to in-house services. The Directives do not explicitly mention in-house services, but there is a common agreement on this, since there is no contractual relationship between two separate legal entities in such cases.

Even if the deal concerns separate legal entities, it may under certain circumstances be regarded as in-house services. In case C-107/98 (Teckal), the European Court of Justice (ECJ) declared that an arrangement with a distinct legal entity that is closely connected with the procuring entity, can also sometimes be looked upon as an in-house arrangement and thus fall outside the scope of the public procurement directives. The reason for this being not to make unnecessary obstacles for an authority in its efforts to organise its activities in a practical and serviceable manner.

In cases of arrangements with distinct legal entities, the ECJ has set out 2 conditions for this to apply: 
1. The procuring entity must exercise over the supplying entity "a control which is similar to that which it exercises over its own departments".
2. The supplying entity must carry out "the essential part of its activities with the controlling local authority or authorities.

According to succeeding case-law from the ECJ, the second condition will be fulfilled if at least 80 % of the providers' business is directed to the related procuring entity or entities. In a later case, C-26/03 (Stadt Halle), the in-house question as to purchase from a separate legal entity is addressed in paragraph (49), which says:

"In accordance with the Court'sTcase-law, it is not excluded that there may be other circumstances in which a call for tenders is not mandatory, even though the other contracting party is an entity legally distinct from the contracting authority. That is the case where the public authority which is a contracting authority exercises over the separate entity concerned a control which is similar to that which it exercises over its own departments and that entity carries out the essential part of its activities with the controlling public authority or authorities (see, to that effect, Teckal, paragraph 50). It should be noted that, in the case cited, the distinct entity was wholly owned by public authorities. By contrast, the participation, even as a minority, of a private undertaking in the capital of a company in which the contracting authority in question is also a participant excludes in any event the possibility of that contracting authority exercising over that company a control similar to that which it exercises over its own departments."

The plural form "authority or authorities" in both the "Stadt Halle" and the "Teckal" cases is considered to mean that the second condition may be fulfilled by adding up activities with several owners of the entity. Thus it does not matter if there are four or more owners, as will be the case here. Moreover, in Eress' case 100% of the services are rendered to the owning partners.

It has not until last autumn been certain whether the first condition may be met if the procuring entity shares the control of the supplying entity with other contracting authorities, which is the case with ERESS. In September 2009, however, the ECJ gave an opinion in Case-573/07 (Sea Srl), where it is stated in paragraph (55) that:

 "The case-law does not require the control exercised over the contracting company in such a case to be individual, and it is recognized that when several public authorities own a company to which they entrust the performance of one of their public service tasks, the control which those public authorities exercise over that entity may be exercised by them jointly."

Consequently the control exercised by the partners or members of a company jointly may be classified as similar to the control they exercise over their own departments. The ECJ holds this to be the case when:
- the company's (Eress') activity is limited to the territory of those authorities (the owners) and is carried out essential for their benefit, and
- through the bodies established under the company's statutes made up of representatives of those authorities, the latter exercise conclusive influence on both strategic objectives of the company and on its significant decisions.


Will Eress’ purchases of services, goods, etc. be subject to public procurement law?

Eress shall have to observe the public procurement regulations when entering into a work, supply or service contract.

Consequently Eress must follow the regulations when procuring goods, services or works from third parties, just like the owning infrastructure managers are obliged to comply with public procurement regulations when they are entering into a work, supply or service contract with third parties. As Eress is a "contracting authority" in the meaning set forth in the Directive's Article 1.9 where this definition is given:

"Contracting authorities means the State, regional or local authorities, bodies governed by public law, associations formed by one or several of such authorities or one or several of such bodies governed by public law."
