AN INDEPENDENT <strong>EVALUATION</strong> OF THE LCNF Generates knowledge that can be shared amongst all DNOs Focuses on network methods that are at the trialling stage 4 4 Assessment: Specific replication report(s) exist / are available on request. There is no evidence of a learning dissemination event or webinar. Evidence: The tables in section 12 of the closedown report list all physical components and knowledge required to replicate the outcomes of this project. In addition to this, further detail on any aspects are available from SSEPD via and email provided in the closedown report. There is no evidence of a learning dissemination event or webinar. References: • Trial of Orkney Energy Storage Park; Close down report; June 2015. Assessment: Solution moved to TRL8 (complete and qualified by end of trial), or commercial solution developed suitable for roll out. Evidence: First tier pro-forma states starting TRL as 6. Following the project, it is judged that the TRL has risen to 8 because of the ability to deploy and manage a constraint management contract has been learned through the project.

AN INDEPENDENT <strong>EVALUATION</strong> OF THE LCNF E.5 Fault Level Management 33kV Superconducting Fault Current Limiter (SFCL) Project Title 33kV Superconducting Fault Current Limiter (SFCL) Tier 1 DNO NPG Status Closed LCNF project funding £2,880,000, (total project value £3,200,000) Final LCNF £2,738,724 Project objectives This project was designed to trial a specific piece of new equipment that has a direct impact on the operation and management of the distribution system. The first phase of the project was to identify suitable locations for the installation and undertake a feasibility and systems readiness study to analyse the network, outlining the optimum application and specification, and confirm the business and carbon cases. The second phase was to design, build, install and commission a three-phase 33kV superconducting fault current limiter on the Northern Powergrid distribution network. It was proposed, and following site surveys, agreed with National Grid, that the unit was installed at a 275/33kV substation in South Yorkshire to facilitate future connection of DG and additional load by limiting the likely increase in fault current to within the rating of the 33kV switchgear. Increase in fault level is typically managed through an operational management switching procedure which, in limited circumstances, may increase the risk of loss of supplies to customers.
