Interconnection has successfully completed a tender process for the Converter Stations of the Crete-Athens Interconnection, awarding the contract to Siemens – Terna, a member of the GEK TERNA group, ADMIE (IPTO) Holding has announced.
After the submission of an improved bid on March 26, the contract price was set at 370 million euros, of which 358.6 million euros concern the construction of the converter stations. The remaining 11.4 million euros concern maintenance of these stations.
The contract calls for a 36-month implementation period and will be signed after approval by the Court of Auditors.
The project will be included in the list of the Operational Program “Competitiveness, Entrepreneurship and Innovation” of the NSRF 2014 – 2020.
Τhe tendering procedure for the design, supply and installation of two Converters and a Substation for the DC Electrical Interconnection between Crete and Athens was launched on May 24, 2019.
The tender attracted the interest of world leaders in the industry and on November 1, 2019 the GE-Nari-Mytilineos and Siemens-Terna consortiums submitted binding offers.
The evaluation of the offers submitted by the consortiums, both of which possess strong technical backgrounds and specialized experience in similar projects abroad, required more than four months due to the project’s elevated technical demands.
The technical evaluation was completed on March 13 and the Siemens-Terna consortium’s offer qualified, taking into account all relevant issues related to the interconnection.
Commenting on the tender, the IPTO group’s CEO Manos Manousakis noted: “During these challenging times, the tender process for our
flagship project, amounting to 1 billion euros, was successfully completed without problems.
IPTO will continue to focus all its efforts in order to protect the timely implementation of the project and ensure the safe and reliable power supply of Crete through the mainland system by 2023. Apart from the economic benefits of the interconnection of Crete for all Greek consumers, through the decline of Public Service Obligations (PSO), the implementation of this
project paves the way for accelerated RES integration on the island based on the principles of sustainable development.”
