Shore power goes live at Portsmouth International Port

A major step towards cleaner maritime operations has been completed at Portsmouth International Port, where a new shore power system is now supplying electricity to visiting ferries and cruise ships.

The technology allows vessels to switch off their engines while alongside, helping to improve local air quality and reduce emissions. It is the UK’s first shore power system capable of serving multiple berths, users and electrical frequencies, with up to three ships expected to connect simultaneously. The system is projected to avoid approximately 20,000 tonnes of carbon dioxide equivalent emissions from 2027.

Hybrid-electric vessels operated by Brittany Ferries were among the first to use the system during testing. Cruise ships operated by AIDA Cruises and Phoenix Reisen also participated, demonstrating how collaboration between ports, shipping companies, government and technology partners can accelerate change across the maritime sector.

Projects like this are creating demand for people with skills in electrical engineering, renewable energy, digital technology, marine operations and environmental management. They also show how sustainability is changing the roles and opportunities available across maritime and transport.
