'''Estlink''' is a set of [[HVDC]] [[submarine power cable]]s between [[Estonia]] and [[Finland]]. '''Estlink 1''' was the first interconnection between the [[Baltic States|Baltic]] and [[Nordic countries|Nordic]] [[electricity market]]s followed by '''Estlink 2''' in 2014.  The main purpose of the Estlink connection is to secure power supply in both regions to integrate the Baltic and Nordic energy markets.<ref name=powergen231210/><ref name=oilvoice261210/><ref name=nib>{{cite news

===History===
First plans for a submarine power cable between the Baltic and the Nordic regions were proposed in 1990s.  Negotiations between [[Eesti Energia]], [[Pohjolan Voima]], [[Helsingin Energia]], Graninge (now [[E.ON Sverige]]), [[Latvenergo]], [[Statkraft]] and TXE Nordic Energy, a subsidiary of TXU (now [[Energy Future Holdings Corporation]]) started In 1999, and on 9 October 2001 a contract was signed in Tallinn.<ref name=bt>

The Estlink 1 cable was operated by AS Nordic Energy Link company, founded by Baltic and Finnish power companies. The main shareholder was Eesti Energia with 39.9% of the shares, Latvenergo and Lietuvos Energija had 25% each, and the remaining 10.1% was divided between Pohjolan Voima and Helsingin Energia (operating through their joint project company Finestlink).  On 30 December 2013 the interconnector was sold to the [[transmission system operator]]s [[Elering]] and [[Fingrid]].<ref name=bt080114>

==== Incident in December 2024 ====
{{Main article|2024 Estlink 2 incident}}
On 25 December 2024, an unplanned outage in Estlink 2 reduced the Estonia–Finland cross-border capacity from 1,016&nbsp;MW to 358&nbsp;MW.<ref name="NordPool UMM, 2024-12-26 Fingrid entry">{{Cite web |date=2024-12-26 |title=Unavailability of electricity facilities : Transmission |url=https://umm.nordpoolgroup.com/#/messages/79210ee1-3395-4f75-a972-7b03888b107a/5 |access-date=2024-12-26 |website=Nord Pool — UMM Platform |publisher=[[Fingrid Oyj]]}}</ref> [[Fingrid]] expects the outage to last until August 2025.<ref name="NordPool UMM, 2024-12-26 Fingrid entry" /> At the time of the outage, [[Electric power transmission|electricity was flowing]] from Finland to Estonia at a rate of 658&nbsp;MW. Concerns about potential sabotage have arisen due to recent outages in the Baltic Sea region, although subsea cables are also prone to technical malfunctions and accidents. Finnish Prime Minister [[Petteri Orpo]] confirmed that authorities were investigating the incident.<ref>{{Cite web |date=December 25, 2024 |title=Finland investigates outage of undersea power link to Estonia, Finnish PM says |url=https://www.reuters.com/world/europe/finland-investigates-outage-undersea-power-link-estonia-finnish-pm-says-2024-12-25/ |website=Reuters}}</ref> 

At early evening, the [[Finnish Border Guard]] escorted the tanker {{ship||Eagle S}}, a part of [[Russian shadow fleet|Russia's shadow fleet]] according to [[Lloyd's List]], to [[Porkkalanniemi]]. By early morning on 26 December, both vessels were still near Porkkala. 

A statement released by the [[European Commission]] described the ''Eagle S'' as part of [[Russia's shadow fleet]].<ref>{{Cite web |title=Estonia navy to protect undersea power link after main cable damaged |url=https://www.bbc.com/news/articles/c1elq7lx9qdo |access-date=2024-12-28 |website=www.bbc.com |language=en-GB}}</ref>

===Description===
The total length of Estlink 2 is {{convert|171|km}}, including a {{convert|145|km|mi|adj=on}} long offshore cable, a {{convert|12|km|mi|adj=on}} long onshore cable in Estonia, and {{convert|14|km}} of overhead lines in Finland.<ref name=powergen231210/>  The {{convert|12|km|mi|adj=on}} long underground cable starts at the Püssi substation and runs the coast of the Gulf of Finland at [[Aseri]]. From there the {{convert|145|km|mi|adj=on}} long offshore cable runs to the Nikuviken cable terminal station in Finland. The Nikuviken cable terminal station is connected with the Attila converter station by the {{convert|14|km|adj=on}} long overhead line, which is installed on 63 pylons.<ref name=fingrid231210/>

Estlink 2 is a classic bidirectional monopolar high-voltage direct current connection with line-commutated converter [[thyristor]]s. Its maximum transmission rate is 650&nbsp;MW and it operates with a voltage of 450&nbsp;kV.<ref name=oilvoice261210/>  Its estimated cost was about €320&nbsp;million, of which converter stations cost €100&nbsp;million and cable €180&nbsp;million.<ref name=powergen231210/><ref name=fingrid231210/>  The European Commission has decided to allocate €100&nbsp;million to the project.<ref name=bns120710>

==Estlink 3==

On June 28, 2022, Elering and Fingrid signed a [[memorandum of understanding]] to begin planning for a third submarine cable, EstLink3, with a capacity of up to 1000 MW, expected to be completed by 2035.<ref>{{cite web|first1=Patrycja|last1=Rapacka|access-date=2022-07-27|title=Elering and Fingrid begin planning for EstLink 3 submarine cable|url=https://balticwind.eu/elering-and-fingrid-begin-planning-for-estlink-3-submarine-cable/|date=2022-06-28}}</ref><ref>{{cite web|access-date=2022-07-27|title=Elering ja Fingrid käivitavad ühistegevused EstLink 3 rajamiseks - Elering|url=https://elering.ee/elering-ja-fingrid-kaivitavad-uhistegevused-estlink-3-rajamiseks|website=elering.ee|language=et|date=2022-06-28}}</ref>
