Adequate connections between the components of the complex will be ensured by two medium-voltage power lines of approximately 30 kV and a common length of about 13 kilometers, while the critical point responsible for connecting to the power grid will be the GPO Kępina substation.
The smaller installation, the photovoltaic farm in Mikołajki Pomorskie, has a production capacity of 31 MW on an area of 50 hectares, distributed between PV Mikołajki (5 MW DC) and PV Gdakowo (26 MW DC). In this case, investments have also been made in extensive supporting infrastructure, including nearly 5 kilometers of power lines and a high-voltage line with a length of about 500 meters. The power grid will be connected to the farm through the GPO Mikołajki substation, operating at a voltage of 110/30 kV.
The finalization of formalities related to the implementation was announced in August of this year. The construction of both farms simultaneously began in September, with their completion expected in the spring of 2025.
