It is unique in that, unlike previous installations that depend on electrode stations to transmit the return current under ground or under water, it uses 20-kV XLPE cable to carry this current.
In the case of the SwePol Link, return cables were chosen as an alternative to electrodes in order to pacify local resistance to the project, particularly around Karlshamn.
SwePol Link AB was formed in 1997 to install, own and operate the cable link between Sweden and Poland.
SwePol Link is 48 percent owned by Swedish state-owned utility Vattenfall, 51 percent owned by Swedish state-owned grid Svenska Kraftnat, and one percent by Poland's power grid PSE.
SwePol argues it has experience operating these cables, including its installation of the world's first high voltage direct current link between Sweden and the island of Gotland.
SwePol has not halted the project, but is following the court order to discontinue work along the 38 km (24 mile) stretch in Swedish waters.

The 600 MW submarine HVDC link between Sweden and Poland is owned by SwePol Link AB, a company jointly owned by Vattenfall AB, the Swedish Power Grid (Svenska Kraftnät) and the Polish Power Grid Company (PPGC).
SwePol was put in commercial operation in August 2000.
The SwePol Link converter stations includes a number of technical features.
SwePol Link AB is part-owned by Svenska Kraftnät, the Swedish state power grid operator, by Vattenfall, Sweden’s state-owned major power generator, and by PPGC, the Polish state-owned power grid company.
The SwePol Link will operate at 450 kilovolts DC and is scheduled to come into operation towards the end of 1999.
ABB will supply the submarine high-voltage direct current cable as well as the converter station equipment at both ends of the link which make the conversion between the alternating current systems of the power grids in both countries and the direct current system of the submarine cable link.
The Swedish electricity market was exposed to significant price pressures during to the occurrence of more frequent "dry periods" than originally envisaged.
The negotiations were successful and the direction of power flow is now responsive to market conditions and to the differences among spot prices in NordPool, Gielda Energii, and the European Energy Exchange.
The mediation involved a series of consultations with third parties with influence and impact on the Swepol project itself, among them SwePol, Svenska Kraftnaet, the Swedish and Polish energy regulatory and governmental authorities, and the European Commission.

Turner was appointed by PSE-Electra to develop a long term financial modelling tool for analysing the electrical energy market in Poland.
SwePol Link is a USD 500 million project concerning the construction and operation of an undersea power link between Poland and Sweden.
Turner was engaged by PSE-Electra to analyse the SwePol Link company (owner and operator of the connection) and related agreements governing the purchase and transmission of electricity.
In order to ensure that sufficient electric power is available in Sweden at all times, a power cable link between Sweden and Poland was installed in 1999.
In order to successfully complete the SWEPOL Cable Link Project, Five Oceans Services manufactured specialized cable equipment.
In addition to the above, dedicated support equipment such as high accurate positioning systems (DGPS and USBL), as well as typical inspection and monitoring equipment (Sea Eye ROV and Innovatum Ultra System) ensured that a high level of confidence was achieved and maintained throughout the project
Cheap Nordic hydro dries up(Site not responding. Last check: 2007-11-01)
SCA’s Kurt Lekås complained that not enough use had been made of existing interconnector capacity both between the Nordic countries themselves and with countries outside.
In particular he said tariffs for access to the SwePol interconnector between Sweden and Poland must be reformed in order to make it cheaper for Nordic users to gain access to Polish power.
This is a matter unlikely to be resolved quickly given significant political opposition to imports of “dirty” Polish power — the SwePol link only got off the ground after the project developers had convinced the Swedish authorities that it would be used primarily to export cheap, clean, Swedish power to Poland.
To wspólne przedsięwzięcie inwestycyjne firm Svenska Kraftnät, Vattenfall AB i Polskich Sieci Elektroenergetycznych SA, które utworzyły – realizującą je – spółkę SwePol Link AB ma na celu rozszerzenie współpracy gospodarczej pomiędzy Polską i Szwecją poprzez międzynarodową wymianę i handel energią elektryczną w obu kierunkach.
W listopadzie 1998 roku rozpoczęły się długotrwałe i trudne negocjacje z nowo powstałą spółką córką właściciela połączenia – SwePol Link (Poland), które zostały uwieńczone podpisaniem – w lipcu 1999 roku – umowy, dotyczącej utrzymania i obsługi polskiej części połączenia SwePol Link.
Ubezpieczenie to, wymagane przez SwePol Link (Poland), zabezpiecza PSE-Północ na wypadek ewentualnych szkód powstałych w mieniu i/lub na życiu/zdrowiu osób trzecich, w związku z realizacją umowy utrzymaniowej.
Den två år gamla elkabeln mellan Sverige och Polen, Swepol Link, kostade skattebetalarna 2,7 miljarder kronor.
DI har tagit en närmare titt på flödena på Swepol Link, och statistiken visar att det i själva verket inte genomförts någon elimport över huvud taget sedan startåret 2000, inte ens vid det kritiska vinterläget i februari 2001.
Lars Marketeg, tjänsteman på Svenska Kraftnät och VD på Swepol Link, medger att han ännu inte haft någon annan kund än Vattenfall.
