TARMAC HARNESSES FLEXIBLE ENERGY DEMAND TO DELIVER NEW CAPACITY TO THE UK GRID
Tarmac, the UK’s leading building materials and sustainable construction solutions company, has worked with Open Energi to install Dynamic Demand on over 200 bitumen tanks at its 70 asphalt plants across the UK, helping to build a smarter, more responsive system which supports renewables and the wider UK transition to a zero carbon economy.
After trialling the technology on three sites, Tarmac commenced the rollout at the start of 2015, and by April 2016 had completed its installation at 70 asphalt plants, connecting over 200 bitumen tanks UK-wide.
What this means is the heating elements in each of those tanks, which keep the bitumen warm, can switch on or off in seconds to help National Grid balance electricity supply and demand. Collectively Tarmac’s tanks are providing the grid with capacity that can be shifted in real-time, so they’re able to use more when there is a surplus – for example when it’s particularly windy – and less when there’s a shortfall. This is helping to build a smarter, more responsive energy system which is paving the way for more renewable power and reducing the nation’s reliance on fossil fuelled power stations.
Another benefit Tarmac have seen from the technology is greater visibility and control of their tanks. They’re now able to see remotely if a tank is on when it shouldn’t be or if there’s a maintenance issue. For example, one heating element may be broken causing them to super heat others. Responding to these kind of issues promptly can help Tarmac operate more efficiently and the learnings they are gathering from across all of their sites is helping the business to identify and share best practice. Lastly, but most significantly, it has had no impact on site operations or safety and this is the ultimate measure of success for Tarmac – that they don’t even know it is happening.
