Milford Haven Marina - Low Energy Lighting

The Project

Milford Haven Port, the leading energy port in the UK, has been reviewing its use of energy across its port buildings. The first phase of the project included the installation of over half a MW of Solar PV on 17 port buildings to generate renewable electricity. The second phase included an ongoing review of energy efficiency in key areas including the Milford Haven Marina.

TGE Group was asked to conduct an energy audit on the 328-berth Marina and to advise how energy efficiency could be improved and carbon emissions reduced.

The Solution

TGE Group identified lighting as a key area where efficiency could be improved. A full assessment on current and future lighting requirements was made with a breakdown on the cost and savings of a programme of lighting upgrades.

The approved programme included the upgrade of 80 light and power bollards on the marina pontoons to modern 3 watt LED units, a saving of 48 watts per bollard. This upgrade alone generated an energy saving of over 14,000kWh/year.
The next stage was to replace the marina promenade lighting from 200 x 15 watt incandescent lights to modern 2 watt LED units. With the lights on for ten hours a day, this resulted in a saving of 9,490kWh a year. A further 120 lights will be replaced as part of an on-going maintenance programme with Quayside Estates.

“The Marina was using older style lighting both on the pontoons and surrounding areas,” explained Operations Manager, Mark West. “This project demonstrates how a simple upgrade to modern lighting can have a significant effect on electricity bills, producing an instant cost saving of 77%. All the lights are now more reliable, providing better safety and security around the marina. This was a large Construction Design Management (CDM) project delivering a significant reduction of over 12 tonnes in carbon emissions.”

Fuel Saving

Replacement of all lights generated a saving of 23,506kWh a year, reducing the energy bill by over £3,000. The project will save over 12 tonnes of CO2/year and provide a combined payback of less than two years.
