AGGREGATE INDUSTRIES UNLOCKS AI-POWERED FLEXIBILITY
Aggregate Industries has connected assets to Open Energi’s artificial intelligence-powered flexibility platform, Dynamic Demand 2.0. The platform automatically optimises Aggregate Industries’ electricity demand in real-time to deliver significant electricity cost savings and is providing valuable demand flexibility to support growing levels of renewable generation.
As part of the initial rollout, 40 bitumen tanks at ten of Aggregate Industries’ sites UK-wide have been connected to the platform, which automatically optimises their daily electricity use in response to a variety of signals, including wholesale electricity prices, peak network charges, fluctuations in grid frequency, and system imbalance prices.
Aggregate Industries is accessing the imbalance market via Renewable Balancing Reserve (RBR), a product offered by its renewable electricity supplier, Ørsted. RBR enables Aggregate Industries to tap into the financial benefits of participating in the imbalance market, by reducing its demand at certain times.
Growing renewable generation levels have increased volatility in the imbalance market. Prices can spike very rapidly when there is a shortfall in supply and this has created valuable opportunities for businesses able to quickly reduce their demand for short periods.
Open Energi has worked with Ørsted to fully automate this process, so that Aggregate Industries’ assets can respond at the click of a button. Open Energi sets the strike price at which they will participate, and Dynamic Demand 2.0 checks their availability, with savings shared between the three parties. On average, Aggregate Industries’ assets are responding to three 30-minute RBR calls a day.
By stacking value streams and automating participation, Dynamic Demand 2.0 ensures Aggregate Industries gets the most from its demand flexibility and mitigates uncertainty associated with changing markets and policy. Aggregate Industries plans to expand its use of Dynamic Demand 2.0 to 48 asphalt plants in total – representing up to 4.5MW of demand flexibility, and is looking at other assets and processes which may be suitable.
Since 2011, Open Energi have connected over 3,500 assets at over 400 sites, working with leading business, suppliers, developers and technology partners to deliver innovative solutions that put our customers in control of how, when and from where they consume electricity.
