The Resilience as a Service – RaaS – innovation project seeks to improve the operational resilience of electricity distribution networks in remote areas.
The aim is to develop and trial a new market-based solution which can swiftly and automatically restore supply to customers in the event of a fault, using services provided by a local Battery Energy Storage System (BESS), and incorporating local Distributed Energy Resources (DER).
In addition to demonstrating the technical concept, the work will develop the commercial framework for RaaS – evaluating the financial case from a DNO perspective and assessing the investment case for RaaS Service Providers with options for revenue stacking in other flexibility services markets
The RaaS concept would deliver low carbon, cost effective network resilience to improve security of supply for communities in areas susceptible to power outages, supporting the UK’s transition to Net Zero.
The first phase of the project focused on site selection, system design for the chosen demonstration site, and refinement of the business case for RaaS. The purpose of this stage was to evaluate the technical feasibility and financial viability of the RaaS concept.
Following a positive stage gate decision, the project is now proceeding with the trial phase and deployment of a demonstration scheme for detailed testing and live operation.
