Ships to plug into clean electricity at Portsmouth International Port
The new system's being launched to help cut emissions
Last updated 21 hours ago
A pioneering project to allow ships entering Portsmouth to plug into clean electric power is underway at the International Port.
Sea Change will allow up to three ships at a time to access multiple electrical frequencies at the same time from spring next year.
It means they will be able to switch off their engines while alongside and operate under battery power when entering and exiting Portsmouth harbour.
Bosses say the project is set to to help avoid emissions of around 20,000 tonnes of CO2e from 2027.
Works began this week, starting with the digging of a trench to lay a 600-metre, 33-kilovolt cable underneath the port’s car lanes to connect the system to the electricity supply.
The system will utilise an extra 15MVA (megavolt amps) capacity secured by the port from Scottish and Southern Energy in 2023, which is all generated from clean, renewable sources.
The project has been funded with £19.8 million from the Department for Transport and £4.6 million from Portsmouth City Council, along with a further £3 million from the council to secure the power necessary for the system.
Brittany Ferries, one of the Sea Change project partners, has also made a significant investment of €550 million to renew five vessels in the fleet, including two new Portsmouth-based LNG-electric hybrid ferries, and will be the main customer using the shore power system.
Maritime Minister Mike Kane said: “UK shore power is crucial in making the sector greener and that’s why it’s fantastic to see this £19.8m help decarbonise one of the UK’s busiest ports.
“Plug-in technology is key to reducing domestic shipping emissions, and I know that ports across the UK are already working on decarbonisation plans.”
Cllr Kimberly Barrett, Portsmouth City Council Cabinet Member for Climate Change and Greening the City, said:
"The Sea Change project will mean the port, its customers and the city as a whole can all make large strides towards our ambitious sustainability goals, and it’s really exciting to see work now taking place.
"The shore power system will have the potential to help the port avoid 20,000 tonnes of carbon emissions per year from 2027, and importantly, improve air quality for Portsmouth residents.
"Portsmouth is leading the way when it comes to innovative, sustainable technology and this is a huge opportunity for the city and also the industry to learn from the Sea Change project."
Christophe Mathieu, CEO of Brittany Ferries, said:
"An integrated approach to sustainability is essential if shipping is to achieve net zero by 2050.
"Ship owners, fuel companies, port partners and government bodies all have a role to play and this is why the Sea Change project is so important.
"It allows the potential of our plug-in hybrid ships to be realised and that benefits everyone.”
Alongside the digging of the trench and laying of the cable, complex engineering works will also take place on the three berths where shore power will be provided, with installation of a flexible cable management system that will enable ships of different shapes and sizes to plug in.
Brittany Ferries’ two new ships will launch in the new year, and will both be able to use the system as soon as it is ready. The system will also be able to accommodate any shore-power-ready cruise ship that calls into the city.
