Mostostal Warszawa has announced the commissioning of an 18.3 megawatt photovoltaic plant in Janikowo, near Inowrocław in northern Poland. The net contract value totalled PLN28.79mn ($6.67mn), covering the design, engineering and construction of the site. The project is one of the country’s first hybrid facilities, combining a solar power plant and a wind farm through a single grid connection point.
Shared grid access for solar and wind
A key feature of the project is the use of so-called cable pooling technology, which enables the shared use of existing grid infrastructure by two distinct generation sources. This setup reduces logistical costs and optimises network capacity. The plant spans 27 hectares and includes 29,673 bifacial panels mounted on single-axis trackers.
The scope of works carried out by Mostostal Warszawa covered all supporting infrastructure, including internal roads, electrical and telecommunication systems, as well as an expansion of the Main Receiving Point. Delivered as a turnkey project, the facility has been fully integrated into the national grid.
Operational deployment in the solar segment
The commissioning of the Janikowo plant reflects the active expansion of Mostostal Warszawa’s renewable energy portfolio. The company has also delivered smaller-scale projects, such as a 150 kilowatt-peak photovoltaic installation on the roof of its logistics centre in Urzut. These investments highlight the group’s capacity to manage various project scales.
According to Mostostal Warszawa’s Contract Group Director, the completion of this project demonstrates the company’s ability to execute technically demanding operations in the renewables sector. The hybrid model, combining two intermittent energy sources on shared infrastructure, is seen as a strategic approach to enhance yield and grid flexibility.
A shifting landscape for national power deployment
This type of hybrid project signals a structural shift in how power generation assets are being deployed in Poland. Aggregating renewable sources at a single connection point enables better utilisation of installed capacity and a more responsive approach to fluctuating demand.
The Janikowo site therefore marks a milestone in the operational transformation towards integrated production systems. This model could potentially be replicated at other industrial or agricultural sites, depending on available grid access and infrastructure cost-efficiency.
