The two important tenders concerning the Enipea Dam in Farsala and the double Dam on the Tavronitis River in Crete received their first extension. According to the decisions of the Ministry of Infrastructure, the expression of interest for the two projects is postponed to November 30.

The reasons for the extension

As both decisions state, “requests for clarifications and additional information have been submitted by interested parties, which refer to different articles of the Phase A Invitation and the need to specify and/or change its special conditions, as well as requests to extend the deadline for submission Expression of Interest Files”.

The Ministry of Infrastructure and Transport responded positively to these requests as, as stated, it took into account “the complexity and requirements in drawing up the Expression of Interest File of the interested Economic Bodies or their associations and the submission of a significant amount of documents and certificates, as well as the time-consuming procedures for their release, given the current circumstances in the global economy in recent months”

The two tenders are implemented using the Public-Private Partnership method. The Contracting Authority is the Ministry of Infrastructure. The above two projects follow the example of the Havria Dam in Halkidiki which has been underway for about two years. The object of the two projects is:

– for the Enipea Farsala Dam, the study, Construction, Financing, Operation and Maintenance of the Enipea Farsala River Dam (in the Palioderli location), Water Distribution Networks and other Associated Projects.

– for the double Dam on the Tavronitis River, Water Resources Utilization projects will be carried out.

Let’s remember that the expression of interest for the two projects was initially scheduled for October 31, 2022.


Upon completion of the expression of interest, an evaluation of the schemes will be carried out and the approval of those deemed to meet the criteria that have been set will follow. In Phase B, the exact scope of the project will be determined (dialogue) and the binding offers will be given from which the contractor of the project will emerge.

The duration of the two PPPs is set at 360 months (30 years). The first 4 years concern the construction/upgrade of the infrastructure and the remaining duration concerns the period of operation and maintenance.

The cost including VAT for the Enipea Dam was set at 230.07 million euros (185.54 million euros without VAT) and for the Tavronitis Dam at an amount including VAT of 267.09 million euros (amount without VAT 215.4 million euros ).
