Belgian water treatment plant cuts annual carbon emissions by 4,000 tons

With automated Demand Response, this energy-intensive facility, serving more than two million citizens, has reduced power demand by up to 5MW with no impact on asset performance.

Minimizing contributions to climate change

This Belgian water treatment plant is a major player in the water and sewage treatment business, serving more than two million residential and business customers.

Sustainable development is a top priority. The company works hard to minimize the impact of its operations on climate change through energy management investments, improvements in pumping systems and a comprehensive energy management program at its corporate headquarters.

Unlikely candidate for Demand Response

The company’s primary objective is to deliver excellent service reliability to its customers. This requires constant pressure across its 5,000+ kilometer distribution pipeline network to minimize leakages and avoid water impurities in the delivery process. Initially this process seemed like an unlikely candidate for Demand Response (DR).

The Head of Operations had assessed a range of options for engagement with DR from several suppliers. However, at the final stage of the assessment, the company decided to partner with Centrica Business Solutions, encouraged by the usability of its automated DR technology platform. This enabled pumps and motors between reservoirs at the treatment plant to participate in DR.

The results

Centrica Business Solutions delivered a fully automated DR solution by reducing power demand from the upstream pumping stations and other equipment.

This created a reduction in load of 5 MW, available in less than three minutes, with no effect on water throughput or pipeline pressure. The control room operators retained 100% control over the industrial process as its proprietary hardware unit ensured that on-site industrial boundary constraints, such as water or pressure levels, were always met.

Operators can fully concentrate on the core business, as the Demand Response process is entirely automated.”
