IPTO announces provisional contractors for island substations

Posted on by admin

TERNA and a partnership comprising Nari and Electromec have been named provisional winners of a tender staged by power grid operator IPTO for contracts to develop substations at the Greek islands Folegandros, Milos and Serifos, all planned to be interconnected to the mainland grid by 2025.

TERNA was named provisional contractor for the development of substations on Folegandros and Milos, the first section of the tender, while Nari and Electromec were named provisional contractors for a substation on Serifos, the second section of the tender.

IPTO aims to have contracts signed for these projects by June. These two tenders are part of the fourth phase of grid interconnections linking the Cyclades with the mainland.

Interested parties faced a July, 6, 2022 deadline. A total of six companies or partners submitted bids for this tender, three for each section.

IPTO has already awarded contracts for the installation of subsea cables to link Folegandros, Milos and Serifos with the mainland grid. The winning bidders were announced by the operator last November.

Hellenic Cables was awarded a contract to install subsea cables from coastal Lavrio, southeast of Athens, to Serifos and from Serifos to Milos, two sections covering a total length of 170 kilometers and priced at 195 million euros.

The Prysmian group was awarded a contract to install subsea cables from Milos to Folegandros and Folegandros to Santorini, two sections covering a total length of 127 kilometers and priced at 150 million euros.

The 4th phase of the Cyclades grid interconnection is budgeted at 524 million euros in total, of which 165 million euros is being covered by the recovery fund.

Once completed, the 4th phase of the Cyclades grid interconnection is expected to reduce annual carbon emissions by approximately 150,000 tons, create grid capacity of up to 730 MW for the development of RES facilities in the region, and also significantly reduce public service compensation (YKO) surcharges added to electricity bills for subsidizing high-cost local power generation on Greek islands.

Power grid operator IPTO has moved ahead with the second stage of a tender for a grid interconnection to link the islands Serifos, Milos and Folegandros with the mainland. This project represents part of the fourth phase of the Cyclades interconnections.

IPTO’s tender is divided into two parts, the first concerning mainland and subsea cable installations for interconnections linking coastal Lavrio, in the wider Athens area’s southeast, with Serifos and, by extension, Serifos with Milos. The second part of the tender concerns subsea cable installations linking Milos with Folegandros and Fologandros with Santorini.

According to sources, a total of four offers have been submitted to the tender’s two parts, two for each.

A tender for the installation of three substations, on Serifos, Milos and Folegandros, is also in progress. A total of six offers have been submitted to this tender. Their technical and financial details are currently being appraised.

IPTO hopes contracts for the two tenders can be completed within the current year so that the projects can be developed in 2023.

The fourth phase of the Cyclades interconnections includes a project for Santorini. Its development has been in progress since early May and, according to IPTO president Manos Manousakis, is expected to be completed in the first half of 2023.

Damco Energy and China’s Xian Electric were awarded the Santorini project’s substation contract, while Hellenic Cables has taken on the cable installation work.

 

PPC Renewables requests geothermal units on islands

Posted on by admin

PPC Renewables, through a consultation procedure, has requested RAE, the Regulatory Authority for Energy, to include planned geothermal units in its RES development plan for the non-interconnected islands Lesvos, Milos, Kimolos and Nisyros.

PPC Renewables called for the installation of geothermal stations with a capacity of 8 MW on Lesvos, which would fully cover capacity planned through biomass-biogas stations, difficult to develop on islands, as well part of the capacity that had been planned through hybrid stations.

In addition, PPC Renewables has requested a geothermal unit of at least 5 MW for Milos and Kimolos, as well as a geothermal unit with a 5-MW on Nisyros.

According to the National Energy and Climate Plan, geothermal units offering a total capacity of approximately 100 MW are envisioned for installation and operation by 2030. The aforementioned islands, offering geothermal potential, are expected to partially cover this geothermal capacity.

PPC Renewables plans to begin developing geothermal stations on Lesvos and Milos within the next two years.

Ilektor named PPC Renewables partner for geothermal fields

Posted on by admin

PPC Renewables has named Ilektor, a member of the Ellaktor group, as its strategic partner for development of four geothermal fields in Greece following the completion of an older international tender that had remained stagnant.

Ilektor emerged as the highest bidder, followed by Terna Energy, for the utilization of geothermal fields in Lesvos, the Milos-Kimolos-Polyaigos island complex, Nisyros and Methana to generate electricity.

A license held by PPC Renewables’ parent company, power utility PPC, offering exclusive exploration and production rights for these geothermal fields, was recently extended by the Greek State.

Ilektor, the strategic partner, will be given a majority stake in an SPV formed by PPC Renewables for this project.

The SPV will take on financing, construction and operation of geothermal field-linked power stations with capacities of 8 MW for Lesvos and 5 MW for each of the three other areas.

PPC Renewables aims to begin geothermal exploration activities at the Milos-Kimolos-Polyaigos group of islands by the end of this year, when it is believed local communities will have been informed and offered their consent.

According to the project’s schedule, a power station fed by the Milos-Kimolos-Polyaigos field should be ready to operate by 2025.

Development of the Lesvos, Nisyros and Methana fields will be left for later on.
