Vivaqua turns water treatment flexibility into demand response payments with REstore
By temporarily curtailing power demand from its upstream pumping stations, Vivaqua is able to reduce its power demand by up to 5 MW during Demand Response events. And in doing so prevents 4 000 tonnes of carbon emissions every year.
Vivaqua is a major player in the water and sewage treatment business, serving more than two million domestic and business customers in Belgium including the entire Brussels area.
Vivaqua borrows water from the environment, stores and treats it to world-class standards, and safely distributes it to its customers. Over the past five years, Vivaqua has invested heavily both in sewage treatment and in improving drinking water quality.
Sustainable development is a top priority at Vivaqua. The company works hard to minimise the contribution of its operations to climate change through energy efficiency investments, improvements in pumping systems and a comprehensive energy efficiency programme at its corporate headquarters.
“Operators can fully concentrate on the core business, as the Demand Response process is entirely automated”Pierre Granville, Technical Director
Vivaqua’s primary objective is to deliver excellent service reliability to its customers. This requires constant pressure across its 5 000+ kilometre distribution pipeline network to minimise leakages and avoid water impurities in the delivery process. Initially this process seemed like an unlikely candidate for Demand Response.
Vivaqua’s Head of Operations had assessed a range of options for engagement with Demand Response from several suppliers. However, at the final stage of the assessment, Vivaqua decided to partner with REstore, encouraged by its automated Demand Response technology platform FlexPond™. This enabled the use of a major buffer present between two water reservoirs upstream at the Tailfer Treatment Plant and close to the raw water sourcing facilities.
In 2012, Vivaqua decided to enrol in Demand Response with REstore to offer tertiary reserves to the grid operator. REstore delivered a fully automated Demand Response solution via the FlexPond™ platform 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 3 minutes, with no effect on water throughput or pipeline pressure. The control room operators retained 100% control over the industrial process as REstore’s Flextract™ unit ensured that on-site industrial boundary constraints, such as water or pressure levels, were always met.
