Project goal
Deliver a safe, standards-compliant connection of the Konin biogas CHP plant to the medium-voltage grid.
The design integrates two CHP units, optimises biogas utilisation and supports local renewable generation.
Project footprint
- Konin – biogas CHP plant and grid infrastructure
Scope of work
- MV grid connection design in line with DSO requirements.
- Engineering of the medium-voltage cable link between the plant and the grid.
- Selection and siting of the container transformer substation.
- Coordination of grid operator approvals and investor requirements.
- Assessment of technical constraints and local site conditions.
- Integration of two biogas CHP units into the electrical design.

Challenges and solutions
Meeting grid operator requirements
The project had to satisfy strict technical and formal conditions for MV connection.
Nivato solution
We prepared comprehensive execution documentation and managed stakeholder approvals at every stage.
Siting the transformer substation
The container substation needed to fit the existing land use while ensuring operational safety.
Nivato solution
Detailed land-access studies led to a layout that minimises site impact and supports safe operation.
Integrating dual CHP units
Synchronising two biogas CHP engines required precise alignment with grid parameters.
Nivato solution
We designed control and protection schemes that maintain stable export conditions.
