Skanska got the green light on works at London’s Euston Train Station to demonstrate the potential of solar-powered off-grid temporary lighting, which would contribute sustainability benefits and cost-savings to the major infrastructure project.
Temporary lighting was needed to illuminate night-time working and to protect site security on the project. The project was to replace and upgrade an electricity substation at Barnby Street, NW1 for Network Rail.
With no mains power on site a temporary off-grid lighting solution was needed for night-working and site protection. As the substation site was next to a residential estate, it was important that all reasonable efforts were made to reduce site impacts, such as noise and fumes from generators. The lights needed to be easy to install and avoid pinning of cables to the hoarding fence which could be a hazard.
Skanska chose to setup our ProTemp Temporary Solar Street Light to provide powerful and reliable lighting at the Euston site, with no noise or emissions. As it does not use mains power, the ProTemp dispenses with the need for a contractor to dig trenches, install trunking and cables and saves significantly on groundworks and installation costs.
The lights removed the need for temporary diesel generator lights, which would have been the only alternative to mains connection at Barnby Street.
Mounted on a concrete base, the stand-alone ProTemp tower light can be moved into position quickly and easily with a forklift or sack truck. Eight lights were positioned around the perimeter of the Barnby Street site until the completion of the contract.
The ProTemp lights continue reliably even when winter days are dark and short. Every ProTemp is fitted with smart Passive Infrared Sensor (PIR) to optimise power usage. A bright light is activated when the area is entered by a vehicle or person. When the area is unused this ‘smart eye’ technology switches the light to a lower lux level to save battery usage and minimise light pollution.

I was familiar with the off-grid benefits of Prolectric solar lighting from previous trials, so I knew using the ProTemps at Euston would mean reliable site illumination without mains electricity, saving on utility charges. As the site is near a residential estate, it was important to reduce impacts such as noise. My role at Skanska is to promote renewable equipment – solar-powered alternatives help reduce environmental impacts and save on project costs.

A 97% diesel reduction at the first attempt is a great achievement. Saving close to 6,000 litres is like driving a family car at 40 mpg twice around the world. It’s clear where we’ve learnt lessons from Llanwern to close that small gap. We want to reach 100% fuel-free by our next rail renewal project. These technologies are a complete game-changer, and we need to get to where this is business as usual.

Highways England’s environmental strategy seeks to help protect, manage and enhance the quality of the surrounding environment.
The use of Prolectric solar powered lights on the project is an excellent innovative approach by the A14 Integrated delivery team. The use of renewable power sources on the A14 scheme helps us to work in greater harmony with the environment.
