Progress of works

The construction of LitPol Link power interconnection between Poland and Lithuania is progressing according to the planned timeline.


The overall investment process has been highly complex and lengthy. The project was divided into two milestones: the preparatory stage, involving administrative work to obtain all necessary building permits and authorisations, followed by construction works and commissioning stage.

The first milestone has been successfully completed in both countries. Preparations followed a similar pattern on both sides of the border. All necessary procedures were completed, i.e. designing different investment variants, environmental impact assessments, selecting the optimum route, design work, amending local spatial development plans, acquiring the rights of way, payments of compensations and indemnities, change of the use of the land into non-agricultural land and non-woodlands, geotechnical investigations, and finally, obtaining the building permits. Each and every major milestone of the investment was accompanied by public consultations, and the decision on the final LitPol Link route was taken after several consultation sessions had been organized with the local residents, during which the initiative has taken its final shape.

Special attention has been paid to share the relevant information with the public, promote the project, and to launch public consultations at the earliest possible stage of the project in order to present and discuss the location of the investment as openly and transparently as possible. There were international and local conferences taking place for all stakeholders, attended by the local authorities and environmental protection organizations, public officials and the press. The purpose of those sessions was to present and discuss investment plans, the nature of the project, and the impact on the regional development. The public had access to the project documents, reports and test results, according to the relevant laws and regulations. During meetings with local communities, the residents had the chance to ask questions, engage in discussions and obtain information about all aspects of the investment and its environmental impact. There were sessions with local authorities and local government officials dedicated to formal aspects, associated with the construction of the power interconnection.

Preparatory works for the investment have been executed by independent contractors. Contractors were chosen by the investors according to the recognised public procurement regulations and guidelines. The same principles were followed in contract-awarding for construction works to the companies, which execute construction works and prepare the project for commissioning.

The success of the project is contingent upon careful planning and coordination of works. With well-advanced construction works scheduled to continue for around two years, we are now heading towards the end of the project. Please be reminded that the preparatory and planning stage took as long as five years to complete both in Poland and Lithuania Artūras Vilimas, CEO of “LitPol Link”

The construction works in both countries have been running in parallel from the spring of 2014 and are scheduled to be completed towards the end of 2015.

An erection site with foundations must be first prepared for each tower, which is then mounted on site step-by-step. When a number of towers are erected, the transmission line can be suspended over a particular stretch of ground. The same construction process must be repeated 297 times along the distance of 112 km in Poland, and 150 times in Lithuania, to build a 51 km long transmission line. The construction of each substation can extend over the area of several hectares of land and includes works on drainage and earthing systems, cable ducts, access roads, necessary foundations, equipment assembly, tens of kilometers of cables and connections, integration of the substation facilities with the power grid control and supervision systems, as well as preparation to work in the National Grid System. Despite the huge complexity of works, it will take only 3 years to complete the construction of all substations.

The investment also involves plenty of accompanying works, such as the construction of temporary access roads, tree cutting, land cleaning, or reconstruction of colliding or crossing objects. In the event any damage is made as a result of investment works, involving either public or private property, compensations are paid and the damage is repaired.

In Poland, alongside the power interconnection between Poland and Lithuania, eleven projects are implemented in parallel to expand the existing power transmission grid in north-east of Poland. There are four overhead power transmission lines currently constructed or upgraded, altogether 400 km long, along with seven power substations in Mazowieckie, Podlaskie and Warmińsko-Mazurskie provinces. These are well-timed and essential investments to allow smooth power transmission over the new interconnection. Works on individual facilities will be completed ahead of the scheduled commissioning date for the transmission line between Ełk Bis and Alytus substations, which leaves more time to run tests and to prepare for the transmission power to be switched on.
