Tereos helps sweeten potential power shortages
With clear targets for energy efficiency and reducing its carbon footprint, Tereos partnered with REstore to curtail its wheat mill and be able to return electricity to the city of Aalst during power shortages. This combined an answer to some of the energy challenges imposed by our changing world with strong support for the company’s local community.
Tereos, the third largest sugar producer in the world, the largest in France and the second largest in Brazil, transforms raw agricultural materials into sugar, alcohol and starch. Tereos is a cooperative group that unites 12 000 cooperative partners around the world. Tereos is placing corporate social responsibility at the heart of its strategy. The company has clear targets, including reducing the energy required to produce one ton of sugar or starch by 20% between 2010 and 2020 and to implement a renewable energy development plan with the aim of reducing CO₂ emissions in its French sugar factories by 20% by 2016.
“We also had the opportunity to deal directly with Elia, but the REstore approach took away the associated risk”Kris Van Hege, Energy Specialist Tereos - plant of Aalst
Located by the Dender River, the Tereos plant in Aalst has processed cereals for more than 140 years. The production site consists principally of a wheat starch plant and a bioethanol facility of which two wheat mills can easily be curtailed. As a large energy consumer, Tereos is constantly looking for opportunities to increase its energy efficiency and to reduce its energy costs. In addition, as the site is located in the heart of Aalst, Tereos commits to reduce consumption and return power to its local community during periods of power shortage linked to peak demand, for example, on cold winter days.
Tereos had the opportunity to monetise this power flexibility directly with the Transmission System Operator, Elia, but found the operation complex and was concerned by the associated risk. Working with REstore, the company launched a project to reduce its energy consumption in periods when energy was scarce and therefore expensive. Tereos appreciated REstore’s consulting approach and found the company to be an experienced partner with great knowledge and understanding of the subtleties of the full range of applicable reserve programmes. In particular, REstore was able to spread the risk with a portfolio of other participants. During daily operations, there is little or no communication necessary on Tereos’ side - REstore’s Flextract™ technology 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 Response participation has grown, the initial trial in Aalst will be developed in the company’s French factories.
