    The European Commission has decided to award a grant to DESFA after an online application by DESFA , TSO, on 27th April 2016 to INEA (Innovation and Networks Executive Agency) for the Action, conduct a study: «Front End Engineering Design (FEED) Metering Regulating station at Nea Messimvria for the interconnection with TAP». The grant for the action is of a maximum amount of EUR 243,250 (50.00% of the eligible costs of the action) in the framework of CONNECTING EUROPE FACILITY (CEF) - ENERGY SECTOR, funding instrument of the European Commission which is managed by INEA under the powers delegated by the European Commission.

    On 5th September 2016 the kickoff meeting of the Grant Agreement took place at INEA premises and the action and its time schedule execution was presented by DESFA and the Grant Agreement was dully signed.

    The Action defines technical requirements design parameters and specifications, operational systems, the main project costs and it identify the key project risks. Thus it facilitates the preparation of the subsequent Engineering Procurement Construction (EPC) tender and contract together with the technical documentation, the cost estimation and the EPC time schedule.

    Procurement was executed in compliance with the "Directive 2014/25/EU of the European Parliament and of the Council of 26 February 2014 on procurement by entities operating in the water, energy, transport and postal services sectors and repealing Directive 2004/17/EC Text with EEA relevance", which was amended by "Commission Delegated Regulation (EU) 2015/2171 of 24 November 2015 amending Directive 2014/25/EU of the European Parliament and of the Council in respect of the application thresholds for the procedures for the award of contracts (Text with EEA relevance)".

    A Safety and an Environmental and Social Impact assessment (ESIA) are included in FEED to justify the site selection in compliance with the National and European legislation. During ESIA a consultation of relevant stakeholders and public authorities took place.

    DESFA in terms of the Action acquired and received the Decision of Approval of the ESIA by the Ministry of Environment and Energy.

    Also in terms of the Action DESFA has obtained the Installation Permit for the Metering and Regulating Station at N. Messimvria and the Ministry of Environment and Energy has issued the Installation Permit.

C. PROJECTS UNDER COMPLETION

  • Aliveri, expansion of the Natural Gas Transmission System

    The project involves the expansion of the high pressure transmission network to Aliveri and includes an onshore section from the main pipeline to the shores of the Euboean Bay, followed by an offshore section to the region of Aliveri and a small onshore section in Evia to the PPC station in Aliveri. The diameter of the pipeline is 20″ and the length of the on shore part is about 57.9 km, while the off shore part is expected to be 14.2 km approximately.

    The pipeline to Aliveri introduces the use of natural gas in central Evia in the urban, commercial and industrial sector, while feeding the new unit of PPC in the region.

    This project is cofunded under the NSRF 2007-2013.

  • 3rd Group of Metering and Regulating Stations

    The scope of the project included

    • the installation of 2 Metering Stations in Aliveri and Megalopoli in order to supply the Power Units of Public Power Coroporation (PPC)
    • the installation of 3 permanent Metering and Regulating Stations at Agioi Theodoroi (Korinthia), Trikala and Karditsa. These Stations supply the distribution networks of Low and Medium Pressure of the respected regions.

  • Megalopoli, expansion of the Natural Gas Transmission System

    The project concerns the expansion of the high pressure transmission network from the region of Agioi Theodoroi (Prefecture of Korinthos), via the isthmus, to the region of Megalopoli, Arcadia.

    The construction of the pipeline is foreseen to be one of 30″, 15.5 km long pipeline and one of 24″, 143.5 km long.

    The purpose of the construction of the project is to supply general industrial/urban areas along the routing (Corinthos, Argos, Nafplion, and around Tripoli, Megalopolis region) and the power generation units with natural gas that will be constructed in Megalopolis. The project was designed in a way to allow for future expansion of the pipeline in the region of the Peloponnese.

    The Project  was cofunded under the NSRF 2007-2013.

  • 4th Group of Metering Stations

    The project pertains to the installation of

    • the Metering Station that will supply natural gas to the power plant “Thisvi Power Generation Plant SA”, (Thisvi, Viotia),
    • the Metering Station to supply the power plant of “ENDESA HELLAS”, (Agios Nikolaos, Viotia)
    • the Metering Station to supply the power plant of “KORINTHOS POWER” (Motor Oil)

D. BIG PROJECTS UNDER FUTURE DEVELOPMENT

  • Compression Station in Kipi

The compressor could operate with smaller capacity. This could be required to serve only the Greek market west of Komotini and for requests for import of gas from Turkey for quantities above the current technical capacity, and / or to ensure reverse flow to the Sidirokastro in cases of increased flow or increased delivery pressure.
