UK’s busiest train station signals significant energy savings

Open Technology’s LiGO control system will provide the exact light levels required across the station, matching lighting use to train timetable, passenger presence, daylight levels and other varying uses. The system is able to ensure maximum savings throughout the year as well as reduce light pollution in the surrounding area.

For the first time, Clapham Junction station will automatically be able to dim the lights down to a minimum value when the station is not in operation or switch the lights off when the station is completely closed. On average, this would amount to savings of 35 per cent of usual lighting use.

Clapham Junction will be the latest in a series of projects that has seen Network Rail and South West Trains work in partnership with Open Technology to introduce intelligent lighting controls. Following an initial installation at Woking Station in 2010, LiGO has now been introduced at 25 stations and train maintenance depots across the Wessex Route.
Installing lighting control is one part of the South West Trains, Network Rail Alliance’s climate change and energy reduction strategy that is estimated to achieve total annual savings of £7m – £12m and a payback period of approximately six years.

‘Reducing our energy consumption is a challenging but crucial aspect of our business. Intelligent lighting has enabled us to save, on average, 20 per cent at each location,’ explained Amy Dickinson, environment manager, Southwest Trains, Network Rail Alliance.

‘An automatic control keeps it simple for us. It enables us to save as much energy as possible, by dimming down and turning off automatically when not in use. It also tracks usage, which helps us to spot any areas for improvement and understand how our buildings are being used.’
