AN INDEPENDENT <strong>EVALUATION</strong> OF THE LCNF E.11 Voltage Control Low Voltage Integrated Automation (LoVIA) Project Title Low Voltage Integrated Automation (LoVIA) Tier 1 DNO ENW Status Complete LCNF project funding £600,000 Project objectives The scope of LoVIA is the deployment of two trial systems on the ENWL low voltage network the objectives of which are to demonstrate the application and integration of new distribution system equipment for the purposes of coordinated voltage control. LoVIA will provide the foundations of a future coordinated LV network voltage control platform and facilitate automated low voltage network operation. Assessment Criteria Accelerates the development of a low carbon energy sector Has the potential to deliver net financial benefits to future and/or existing customers 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. Evidence: This project has shown that an integrated and coordinated voltage control system can be deployed at distribution substations to provide more refined management of voltages on the LV systems (and realise significant voltage headroom) to support the connection of increased low carbon technology. References: • Low Voltage Integrated Automation; Close down report; December 2013. Assessment: Indication that the project is likely to deliver financial benefits to customers. However, the financial benefits and the scale/term of these are not set out. Evidence: The benefits to customers described in the report is in terms of voltage quality delivered. Financial benefits are not specifically set out. References: • Low Voltage Integrated Automation; Close down report; December 2013.

AN INDEPENDENT <strong>EVALUATION</strong> OF THE LCNF Has a Direct Impact on the operation of a DNO’s Distribution System Generates knowledge that can be shared amongst all DNOs 4 5 Assessment: The project has been /is ready to roll out into BAU or outputs are utilised in later LNCF projects. The project has a high likelihood of being replicated by other DNOs. Evidence: Electricity North West plan to carry out a detailed review of the LV planning codes of practice following all of the projects that are being undertaken. This should result in more comprehensive guidance with a wider portfolio of solutions to cater for different network conditions which can be used as part of business as usual. The project solution is not yet implemented as BAU. However, outputs from the project are being used in the follow-on Tier 2 project ‘Smart Street’. 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. References: • Low Voltage Integrated Automation; Close down report; December 2013. Assessment: Specific replication report(s) exist / are available on request. A learning dissemination event or webinar was held. Evidence: As a direct outcome of this project Electricity North West has produced and made publicly available: • The algorithm used to adjust the set point • Communications architecture for the LoVIA system This technical information is contained in the closedown report and in the appendices and is available for download via the Electricity North West website. Electricity North West has presented this project at two LCNF annual conferences.
