  • Ultimately we want to minimise the amount of energy we use whilst providing our customers with the best level of service at the least cost. Open Energi’s tech delivers an income, but it also gives us far greater visibility of how our assets are performing, second-by-second. This insight can help us to optimise our sites for the future – pre-empting maintenance issues, improving resiliency, and thinking more smartly about how we integrate other technologies, such as renewable energy and battery storage.

Severn Trent embraces demand flexibility to deliver a smarter energy future

Severn Trent is working with Open Energi to unlock demand flexibility from its equipment, and aims to provide over 20MW of flexible capacity from across its network by 2020. The company, which provides water to 4.5 million households and businesses across the Midlands and Wales, is using Open Energi’s Dynamic Demand technology to enable equipment such as pumps, motors and blowers to automatically adjust their electricity use second-by-second.

To date, Open Energi’s technology has been installed at two of Severn Trent’s sewage treatment works in Redditch and Leicester. Together these two sites are providing National Grid with around 1.2MW of real-time flexibility. A further six sites are expected to be complete by Q1 2018. Longer term, Severn Trent plans to expand its use of Dynamic Demand to smaller sites and estate buildings.

Delivering a dynamic frequency response service from “always on” assets, within a highly regulated, customer facing industry, is operationally challenging. Open Energi has worked closely with Severn Trent’s operations and process scientist teams to ensure that control protocols are always respected and that the integration has zero impact on process operating parameters.

By tapping fast-acting, invisible flexibility in its existing assets, Severn Trent is providing an efficient, low carbon means of balancing electricity supply and demand, paving the way for greater use of renewable energy across the UK.
