BOS Power’s 250 MWh turnkey battery energy storage project will underpin high-power charging for Molslinjen’s next-generation electric ferries
BOS Power has secured a turnkey Battery Energy Storage System (BESS) contract from Molslinjen, the Nordic region’s leading ferry operator, to supply shoreside energy storage infrastructure supporting the electrification of one of Denmark’s busiest ferry corridors.
The project will deliver battery energy storage systems across two coastal sites serving the Kattegat route between Jutland and Zealand, helping to provide the grid flexibility and charging capacity required for next-generation electric ferry operations.
The contract adds approximately 250 MWh of energy storage to BOS Power’s Nordic portfolio, which now exceeds 500 MWh of delivered and contracted capacity across utility, industrial and transportation applications. It is one of the largest energy storage projects in BOS Power’s history and a milestone in the decarbonisation of Danish ferry transport.
This ferry route is critical regional infrastructure. The Aarhus to Odden crossing is one of Denmark’s busiest and fastest links between Jutland and Zealand. Electrifying the route depends on reliable shoreside energy storage, and the systems must be delivered without compromising the availability these routes are relied upon to provide every day.
Both sites at Aarhus and Odden sit at coastal, port-side locations integrated directly into the harbour and charging infrastructure, making this one of the more technically demanding BESS deployments in the Nordic region. BOS Power acts as full EPC contractor and turnkey system integrator across both sites, carrying the complete scope under a single point of responsibility: design, engineering and permitting support, civil works and construction, mechanical and electrical installation, commissioning and full grid code compliance.
Delivering energy storage of this scale across two separate coastal sites, integrated with the charging and power infrastructure that electrified ferry operations depend on, is a complex undertaking. BOS Power’s ability to manage the entire chain, as one accountable partner, is central to why the project was placed with the company.
Beyond delivery, BOS Power provides integrated lifecycle services including preventive and predictive maintenance, 24/7 remote monitoring, software updates and operational advisory, backed by a Nordic network of offices, workshops, service hubs and logistics facilities.
“This ferry route is critical infrastructure. The Kattegat connection between Jutland and Zealand is a lifeline for the people and goods that rely on it every day, and electrifying the ferries that serve it has to be done without compromising that reliability. Delivering energy storage across two coastal sites as a single turnkey partner, from design all the way through grid-compliant commissioning, is a genuinely demanding job, and it is exactly what BOS Power is built for. We are proud that Molslinjen has placed that trust in us.” – Kim Strate Kiegstad, Head of Energy Storage, BOS Power
“The large onshore battery systems will be at the heart of our transition of the high-speed ferries to electric operation. These batteries are essential to ensuring stable and redundant operations when our ferries need to be charged in both ports. We believe this task is in safe hands with BOS Power.” – Hans-Henrik Simonsen, Technical Director, Molslinjen
