Tereos sweetens power shortage

With clear targets for improving energy efficiency and reducing its carbon footprint, Tereos partnered with REstore (now part of Centrica Business Solutions) to curtail its wheat mill and be able to return electricity to the network during power shortages.

Supporting the local community

Tereos, the third largest sugar producer in the world, transforms  raw agricultural materials into sugar, alcohol and starch. The company has placed corporate social responsibility at the heart  of its strategy and has clear targets, including reducing the energy required to produce one tonne of sugar or starch by 20% between 2010 and 2020.

Flexible approach to energy

Tereos is constantly looking for opportunities to increase its energy efficiency and to reduce its energy costs. In addition, Tereos has committed to reducing consumption and returning power to its local community during periods of power shortage linked to peak demand, such as on cold winter days.

Tereos had the opportunity to monetise this power flexibility  directly with the transmission system operator (TSO), but it found  the process complex and was concerned by the associated risk to its operations.

With Centrica Business Solutions, the company launched a project to reduce its energy consumption in periods when energy was scarce and more expensive. Using Flextract™ technology there is little or  no communication necessary from Tereos’. The solution monitors the process so that when there is a curtailing activation, Tereos’ SCADA system gets the signal and automatically takes the necessary actions to reduce energy consumption.

Now Tereos’ confidence in Demand Side Response (DSR) participation has grown, the initial trial in Aalst will be developed  in the company’s other factories.

The results

The DSR programme is supporting the company’s corporate social responsibility strategy. It is now on track to reduce the energy required to produce one tonne of sugar or starch by 20% by 2020  and to reduce CO₂ emissions in its European sugar factories by 20%.
 

We also had the opportunity to deal directly with the transmission system operator, but this approach took away the associated risk.”
