Objectives The project will require site surveys to be undertaken and data to be collected to understand how the wastewater assets are operating and how much energy they are consuming. Hydraulic models will be developed using weather data and knowledge of the physical constraints of the wastewater system. Outputs from such models will then be input into another model to determine areas of storage capacity and pump turn-down opportunities for a given duration. This project will focus on assets within a single waste water catchment area operated by United Utilities, however the learning will be disseminated and applicable across waste water catchment areas across GB. The objectives of this project are: to assess the technical potential for demand-side flexibility within a single waste water catchment area when operating all assets as part of a wider system to identify technical enhancements needed to operate individual assets as part of a wider system to assess the business case for providing flexibility services via this systemic method of operating assets within a waste water catchment area to support dissemination of any learning to water utilities, as well as other networks, to encourage deployment of this technology across GB if the project demonstrates technical and commercial feasibility
Abstract With increasing deployment of variable, non-synchronous generation and the closure of conventional dispatchable generation, the GB electricity system is becoming more inflexible. Additional sources of flexibility are required to help operate the system. National Grid Electricity System Operator (ESO) is exploring new ways to procure additional flexibility, including exploring the potential for flexibility from the demand side. The Power Responsive programme, which brings together stakeholders from a range of UK sectors, identified potential for additional demand-side flexibility from the water sector.Water systems are built with headroom to protect against rare weather events such as storms, floods and droughts, and it is this system headroom which could be used to provide additional flexibility services. However, it is unclear how large these system-wide opportunities from the water sector are, where they are, how to access them and whether there is a sufficiently strong business case to justify the necessary investment in new technology and processes. The research hypothesis of this project is that providing demand side flexibility through controlling a whole water system is more cost-effective than focussing on a single asset or process.
