Dynamic system is an energy saver

A power balancing system called Dynamic Demand is being installed at 29 operational sites in a phased rollout.

It allows items such as heated bitumen tanks and pumps used to dewater quarries to intelligently shift demand for energy, reducing consumption at peak times and increasing it at quieter periods. This flexibility helps the National Grid manage the system and supports the integration of variable power sources such as wind and solar.

Hanson is paid for providing the service and the technology has no impact on performance.

In addition, Dynamic Demand provides sub-second metering data, which helps to spot maintenance issues, identify energy cost savings and optimise resources.

Chris Kimmett, commercial manager for Open Energi which developed the system, said: “It’s a game-changing evolution in the way we manage energy and we are delighted to be working with Hanson to help adopt a smarter approach.”

Fourteen asphalt plants have already been fitted with Dynamic Demand systems. They are West Drayton, Ardingly, Dagenham, Tytherington, Ettingshall, Baston Fen, St Ives, Northampton, Cliffe Hill (Marini and Quad), Criggion, Bradford, Keepershield and Groby.
