Objectives Determine the minimum requirements from the DNO for the installation of Small-Scale Energy Storage (SSES) to domestic properties - connection/application/notification Define typical load profile of a PV and storage-equipped household for modelling the long term effects of SSES on the distribution network Improve DNOs’ understanding of the residential energy solutions market Gain insights into customer and DNO value propositions from aggregated SSES applications Creation of policy recommendations about notification and permissions Production of load profile(s) for properties with solar PV and SSES to inform business planning load growth forecast model and LV modelling tools
Abstract More than 850,000 solar PV systems have been installed in the UK since 2010. Only a very small number of these systems have any form of electrical energy storage. Today the market is nascent but it is forecast to grow rapidly. As the price of electrical energy storage systems has fallen, their popularity has increased. The roll-out of solar PV systems coupled with small-scale energy storage (and other low carbon technologies) is likely to introduce challenges for the operation of distribution networks. The Electricity Networks Association (ENA) and Imperial College have estimated that changes to meet these challenges could cost more than £10bn by 2030 with 90% of the cost resulting from low voltage network reinforcement. Domestic energy storage has the potential to create benefits for Distribution Network Operators (DNO)s but, being in its infancy, the potential impacts to the network are not well understood. Powervault Ltd estimates a significant benefit to DNOs, based on a review of studies conducted by the ENA, UK Power Networks and recent research by Andrew Crossland and ENWL. The National Infrastructure Commission and Lord Adonis recently estimated that demand flexibility and electricity storage could save the UK £8bn a year and the Carbon Trust recently estimated that energy storage could save £2. 4 billion a year system wide by 2030; if regulatory hurdles are overcome this could rise to £7 billion a year . However, the impacts of domestic energy storage to DNO networks are not well characterised and other benefits to network operation are not understood. Barriers to deployment of domestic energy storage may exist. Current policies regarding notification or permission may need to be updated. A field trial of up to 60 sites with monitoring equipment of up to three different types of domestic energy storage system.Note : Project Documents may be available via the ENA Smarter Networks Portal using the Website link above
