Off-grid power for temporary asphalt plant | Aggreko UK

Aggreko helps £20m refurbishment take off at RAF Valley


RAF Valley is a Royal Air Force station on the Isle of Anglesey that is also used as Anglesey Airport.

The site embarked on a £20 million refurbishment project to extend the runway's life by 25 years and strengthen the taxiway for Hercules, Tornados, Typhoons and Hawk aircraft.

Joint venture partners - Northstone and Whitemountain - contacted Aggreko to provide off-grid power for the temporary modular asphalt plant that was installed to produce materials for the 12-month long project.  

Aggreko's solution

Aggreko supplied six generators to provide a total of 2000 kVA of daytime power to the temporary modular asphalt plant.  

At night, the power provision automatically reduced down to two 200 kVA generators, which powered the plant’s heating system and ensured that the asphalt didn’t solidify.  

The generators were synchronised to share the load, so if one failed, the other could automatically pick up the power requirements. 

Each of the generators was monitored round the clock by Aggreko Remote Monitoring technology, which used GPRS to transmit continuous real-time data from the equipment.  The data was received by Aggreko's Remote Operations Centre, where a 15-strong team of service engineers constantly monitored the equipment and corrected any issues remotely, or if required, dispatched a local service engineer to site.  


Aggreko provided reliable off grid power for this 12 month refurbishment project, using Aggreko Remote Monitoring technology to ensure continuous power.  Load on demand technology delivered a cost efficient solution to meet the fluctuating power needs of the site that changed whether day or night.  

“Aggreko designed a bespoke power scheme to ensure that we could meet the variable power loads of the site as cost efficiently as possible. They were able to deliver a reliable power supply, with smart failsafe technology in place to ensure uninterrupted power to the site.”
