AN INDEPENDENT <strong>EVALUATION</strong> OF THE LCNF Validation of Photovoltaic (PV) Connection Assessment Tool Project Title Validation of Photovoltaic (PV) Connection Assessment Tool Tier 1 DNO UKPN Status Complete LCNF project funding £367,000 Project objectives The project planned to implement clear policy guidelines advising planners when further investigations might be necessary before connecting large clusters of solar panels to the electricity network. The project studied requests for photovoltaic (PV) connections in concentrated areas, like housing estates, so the DNO could develop a draft policy. They are now validating those guidelines. Project objectives were to: • Monitor PV clusters to understand their impact on the low voltage network. • Explore whether PV output information, held by installers, could be used by network operators. • Investigate innovative solutions which can be applied to address network constraints. • Validate planning assumptions in the DNO’s draft connection assessment tool and develop an approved policy to provide more cost effective network interventions.

AN INDEPENDENT <strong>EVALUATION</strong> OF THE LCNF 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: This project focuses on understanding the impact of clusters of photovoltaic generation on the distribution network and validating the photovoltaic (PV) connection assessment tool that the DNO developed (i.e. validating the planning assumptions in the draft connection assessment tool). The next step was then to develop an approved policy to provide more cost effective network interventions. The data is used by the DNO to improve their connection assessment tools and should help to facilitate connection of low carbon generation. The project closedown report shows that there are a number of benefits for the connection of PV application, such as reduced processing time, customers being able to connect more PV without having to pay for network reinforcement and new PV schemes that would traditionally require network reinforcement being more feasible. Carbon benefits are not specifically quantified.
