Tenders Are Invited For Installation Of Pipe System – Transmission & Interconnection Pipelines Of The District Heating Facility Of Kozani With The District Heating Network Joint Of Western Macedonia - Reference Number: Tu 0464/2023
Installation Of Pipe System – Transmission & Interconnection Pipelines Of The District Heating Facility Of Kozani With The District Heating Network Joint Of Western Macedonia - Reference Number: Tu 0464/2023. With This Project, The Kozani District Heating Facility Is Functionally Connected To The Kozani-Ptolemaida-Amyntaios Single Interconnected District Heating System With The Aim Of Ensuring The Coverage Of The District Heating Energy Needs In Western Macedonia Both During The Transitional Stage And After The Withdrawal Of The Existing Lignite Units Of The Region In Implementation Of The National Plan For Energy And Climate. The Project Includes The Construction Of A System Of Underground Steel Factory-Insulated Superheated Water Transport Pipes In Accordance With The European Standard En 13941:2019 (District Heating Pipes - Design And Installation Of Thermal Insulated Bonded Single And Twin Pipe Systems For Directly Buried Hot Water Networks) From The Facilities Production And The Transfer Pumping Station Within The Kardia Npp/Ppc To The Central Transfer & Distribution Pumping Stations Of The Kozani District Heating Facility In The Kasla Area Of The City Of Kozani. The Nominal Thermal Power Transmission Capacity Is Predicted To Rise To 195Mwth, Taking Into Account The Current Peak Of The Kozani District Heating System, As Well As The Thermal Demand Due To The Future Expansions Of The System In Kozani And Neighboring Settlements. Briefly Included: (A) New Superheated Water Transfer Pipe With A Nominal Diameter Of Dn700mm/Φ900mm Consisting Of A Supply Pipe And A Return Pipe (Double Pipe).The Trench Length Of The New Dn700mm Pipeline Amounts To ~ 8.32Kmand Starts From The Interconnection Facilities At The Kardias Npp Up To The Interconnection To The Existing Transmission System Of The Kozani District Heating Within A Bathhouse Included In The Present Project, In A N-Nw Position Of The Settlement Of Drepanos. (B) New Transmission Pipeline Of Nominal Diameter Dn600mm/Φ800mm Consisting Of Supply Pipeline (Single Pipeline).The Trench Length Of The New Dn600mm Pipeline Amounts To Approximately 7.85Kmconnecting The New Bathhouse With The Main District Heating Facilities In The Kaslas Area Of The City Of Kozani. (C) Two New Sections Of New Transmission Pipelines Of Nominal Diameter Dn4500mm/Φ6300mm Consisting Of Supply And Return Pipeline (Double Pipeline).The Trench Length Of The Two Dn450mm Sections Amounts To Approximately 1.02Kmthe Construction Of Which Is Necessary To Interconnect The New Ones With The Existing Pipelines. (D) Cin Order To Ensure The Functionality Of The Project, The Construction Of A Sewage Plant Is Planned, Which Will Be Located Within The Farm Of Drepanou Kozani, On An Area That Is Already Owned By D.E.Y.A. Kozani. With The Above Design Of The Transmission System, The Supply Of The District Heating System With Thermal Energy Will Now Be Done From The Facilities In The Ais Kardia Area. With The Intervention Of The Bath Station In The Drepanou Area And As Long As The Ais Agios Dimitrios Facilities Are Still In Operation, It Will Be Possible To Supply The District Heating Of Kozani From The Ais Agios Dimitrios.
