AN INDEPENDENT <strong>EVALUATION</strong> OF THE LCNF Demonstrating the Benefits of Monitoring LV Network with Embedded PV Panels and EV Charging Point Project Title Demonstrating the Benefits of Monitoring LV Network with Embedded PV Panels and EV Charging Point Tier 1 DNO SSE Status Complete LCNF project funding £320,000 Project objectives This project introduced distribution substation monitoring to obtain detailed and accurate current, voltage, power and directional energy usage data, and to develop an understanding of how DNOs might pursue such deployments in the future using monitoring devices installed at substations. It provided the opportunity to monitor the LV feeder circuit to which SSE’s low carbon homes are connected to gain insight into the impact on the low voltage network. Consideration was given to the monitoring requirements of the Low Carbon Networks Fund (LCNF) Tier 2 New Thames Valley Vision1 (NTVV) project so that monitoring can be deployed with certainty on a larger scale through this project. 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 the connection of low carbon generation or demand. The carbon benefits not specifically quantified. Evidence: Through the project, data analysis from the substation monitoring showed that showed there is capacity for additional connection of around 30 EVs on the feeder to which the low carbon homes are connected, but did not enable quantification of additional PV which could be connected. Therefore, the project has potential to facilitate the connection of low carbon demand. Carbon benefits are not specifically quantified.

AN INDEPENDENT <strong>EVALUATION</strong> OF THE LCNF Has the potential to deliver net financial benefits to future and/or existing customers Has a Direct Impact on the operation of a DNO’s Distribution System - 5 Assessment: Compelling evidence that the project is highly likely to deliver significant financial benefits in the long term (ED2 and beyond) to selected group of customers. Evidence: The closedown report details the financial benefits in Table 11. The main financial benefit for customers is around the connection of new low carbon technology. Benefit would therefore mainly be for customers wishing to connect new generation. References: • Demonstrating the Benefits of Monitoring LV Networks with embedded PV Panels and EV Charging Point; Close down report; Feb 2013. Assessment: The project has been / is ready to roll out into BAU and is being used in an ongoing tier 2 project). Other DNOs have included the project in their business plans. Evidence: It is the outcome of the Tier 2 ‘New Thames Valley Vision’ project that is expected to directly influence SSEPD and other DNOs’ approach to business as usual. The findings from this project are being fed directly into the Tier 2 New Thames Valley Vision Project. Specifically this project 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. The project also 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 £5000 to £1000 per installation. The closedown report states: It is noted that other DNOs (ENWL in particular) have already procured equipment configured by manufacturers on this project for deployment for business as usual activities. This is considered business as usual medium scale deployment.
