AN INDEPENDENT <strong>EVALUATION</strong> OF THE LCNF Smarter Network Storage (SNS) Project Title Smarter Network Storage (SNS) Tier 2 DNO UKPN Status Underway LCNF project funding £13,218k Project objectives This project is trialling how energy storage could be used to defer traditional network reinforcement and evaluating additional benefits that can be gained to maximise the value, and make storage a more cost-effective alternative. In order to achieve these additional benefits, the storage will be used for a range of other system-wide services, to benefit other electricity system participants, and test both the technical and commercial aspects of these applications. The aims are to: • Demonstrate how 6MW / 10MWh of lithium-ion storage can be deployed on the distribution network to support security of supply. • Trial the multi-purpose application of storage for a range of different system benefits to help maximise value, e.g. investment deferral and ancillary services. • Develop a new optimisation and control system and trial the commercial arrangements for shared use of energy storage. Assessment Criteria Accelerates the development of a low carbon energy sector Score (1-5) 4 Overview of assessment, sources of evidence and comments Assessment: The project clearly facilitates one of the carbon benefits: Defer asset reinforcement. The carbon benefits are credible and quantified. Evidence: The project is trialling how energy storage could be used to defer traditional network reinforcement and evaluating additional benefits that can be gained to maximise the value, and make storage a more costeffective alternative In the full submission pro-forma, it is estimated that 6MW of storage capacity, as installed in the project, would provide annual CO 2 emissions savings of 1.7k tonnes of CO 2 when fully integrated.

AN INDEPENDENT <strong>EVALUATION</strong> OF THE LCNF Has the potential to deliver net financial benefits to future and/or existing customers Generates knowledge that can be shared amongst all DNOs Involvement of other partners and external funding - - 4 Assessment: The project is expected to demonstrate benefits to network which are highly likely to be required in the future to benefit storage owning parties and customers. Evidence: As well as deferring network reinforcement, benefits are associated with Triad optimisation, balancing services and the capacity market.

Assessment: Project incomplete not marked The project website has a range of learning documents and details of events to date Evidence: SMS project website References: • Smarter Network Storage learning event March 2014 • Project reports e.g. SDRC 9.7 Successful Demonstrations of Storage Value Streams, SDRC 9.6 SNS 3.12 Analysis of Integrated Energy Storage Contribution to Security of Supply, SDRC 9.5 Electricity Storage in GB: SNS 4.7 Recommendations for regulatory and legal framework Assessment: The project involved some external partners covering some of the main technical /commercial / stakeholder aspects as applicable. Evidence: Project Partners: AMT-SYBEX (information and data exchange); Durham University (development of algorithms); Imperial College London (analysing, modelling and optimising electricity systems, core studies and development of recommendations); KiWiPower (provide and manage the route to market); National Grid (guidance and advice); Pöyry Management Consulting (market and regulatory expertise, analytical services); Smartest Energy (market reconciliation and pricing information) and Swanbarton (overall development support and specialist support in commercial arrangements). Project Suppliers: A123 Systems Inc. (supplier of the energy storage device). Project Supporters: UK Energy Research Centre, IMechE, Electricity Storage Network Full submission pro-forma shows external funding of £1,216k (~8% of total project cost cited (£15,292k)).
