Works to commence on Grosnez Lighthouse

From Port of Jersey
9th March 2021

A programme of works to enhance Groznez Lighthouse on the Island’s north-west coast is due to start this week (w/c 08.03.21).

The joint initiative, which is being undertaken by Ports of Jersey (PoJ) and Jersey Electricity (JE), will see the replacement and upgrade of the mains-powered light on the building to a solar powered LED one as well as the replacement of the existing fencing around the site. Work is expected to take up to one month for overall completion.

Advances in LED and solar technology for lighthouses in recent years has presented an opportunity to provide an alternative solution for Grosnez. As part of the works, JE Engineers will also remove the overhead line that currently feeds the navigation light from this Site of Special Interest. It will also make the colours of the light brighter, the intensity stronger and the cut off between the light sharper.

Grosnez lighthouse, which was built in the late 1940s was last refurbished six years ago. It is administered by Ports of Jersey as part of its public service obligations and is an important aid to navigation for both commercial and local mariners. At night, the red sector also indicates the danger to navigation of the Paternosters reef.

The installation and commissioning of the new LED light is being undertaken by Ports of Jersey’s Harbour Operations Team, working closely with JE and the costs for the project, which has a budget of £12k will be shared equally between the two companies.

Leading the project on behalf of Ports of Jersey, Operations and Commercial Manager for its Marine Services, Donford Nicholas, explains, “We are pleased to be collaborating with Jersey Electricity on this important project to introduce further sustainable solutions to our Aids to Navigation in the Island. Ports of Jersey is constantly looking for more efficient and reliable solutions for our lighthouses, buoys and beacons and we’re delighted to see this reflected in this forthcoming project”.

Jersey Electricity Service Delivery Manager, David Powell, says, “This project shows how two organisations, which are committed to sustainability and willing to invest in new technologies can work in partnership for the benefit of Jersey’s environment and the community”.

Public access to the headland at Grosnez will not be affected by this works programme.
