Investment supporting the energy transition

The construction of the Janikowo power plant is a step towards the decarbonization of Poland’s energy system and the achievement of climate neutrality. Thanks to the application of cable pooling technology and single-axis trackers, the project ensures optimal use of infrastructure and maximizes renewable energy generation.

The scope of work carried out by Mostostal Warszawa included the comprehensive execution of construction, road, electrical, power, and telecommunication infrastructure, as well as the expansion of the Main Receiving Point. The power plant was equipped with 29,673 bifacial panels installed on 27 hectares, which track the sun’s movement to increase energy production efficiency.
