AN INDEPENDENT <strong>EVALUATION</strong> OF THE LCNF Large Scale Storage ENWL – Low Voltage Integrated Automation, Low Voltage Protection and Control UKPN – Short Term Discharge Energy Storage The project outputs are being used in the Tier 2 Smart Street project. The ‘smart joint’ developed in the project is a BAU technique for establishing means of voltage measurement on LV feeders at a point remote from a feeding substation. To-date 200 smart joints have been deployed. The enhanced protection and communication functionality for the Kelvatek load management devices, Weezap and Lynx will allow greater control on the LV network. Enabled UKPN and other DNOs to proceed with larger-scale storage projects, e.g. SNS (UKPN) and CLNR (NPG) SSEPD – LV Network Storage and Orkney Energy Storage Park The project was the first in the UK to prove the theoretical benefits of energy storage such as peak shaving, phase balancing and voltage manipulation. Learning from the project also directly supported the implementation of a number of lithium ion-based energy storage projects within SSE and other DNOs – such as UKPN and NPG. Learning was gained in terms of the safety case installation and operation of the lithium ion batteries, and also in the cost of procuring, installing and operating the batteries. This allowed for the development of a code of practice and the establishment of the Energy Storage Operators Forum (ESOF). Visibility SSEPD – LV Network Modelling & Analysis Identified the appropriate choice of power analysis tool to be used such that the impact of LCTs on the LV network could be appropriately assessed. Learning from the project fed into NTVV. WPD – Electric Boulevards Provided a template for use as part of the planning toolset as and when the increase in demand for Electric Buses comes to fruition.

AN INDEPENDENT <strong>EVALUATION</strong> OF THE LCNF SSEPD – Impact of Electrolysers on the Network The knowledge generated in the project will help DNOs to prepare and understand the potential impact of the wide-spread adoption of hydrogen vehicles including the potential impact of a rollout of hydrogen refuelling stations and the alternative operational modes. This could avoid adding to local peak demand, reducing generation constraints, and also help avoid reinforcement. It could allow more renewable generation on to the grid and improve the amount of 'green' hydrogen which could be produced. WPD / UKPN – LV Current Sensor Tech Evaluation SSEPD – Benefits of Monitoring LV Networks Enabled GB DNOs and vendors to better understand requirements and challenges, leading to better and cheaper LV monitoring products and practices. Demonstrated that they can be installed extremely quickly and efficiently. Proved safety aspects of fitting monitoring equipment into live distribution substations and enabled NTVV to progress with substation monitoring to the time line necessary for the provision of data. Highlighted the high cost of monitoring and installation and initiated ‘price challenges’ on innovation via the EiC. Early outcomes indicate that monitoring costs can be reduced from £5,000 to £1,000 per installation.
