Carbon Emission Reduction Technologies
The Energy Networks Association (ENA) represents all of the UK DNOs. Several projects have been initiated by the ENA R&D Working Group and have been funded through the IFI.
Various projects completed and reported in previous years and for that reason these are not reported here. The projects listed below address issues which have been identified by the ENA Working Groups as significant issues requiring technical investigation and development:

  • Harmonic Impedance Modelling – The project addresses the detailed modelling of cable and overhead line components, to develop cable models appropriate for distribution networks

  • Earthing Project – HV/LV Earthing Transfer: The aim is to develop new techniques to assess the impact of lower voltage earth electrodes on higher voltage ‘hot zones’ and to measure the resistance of distribution substation earth systems

  • Smart Grid Forum Workstream 3 Phase 1 & 2 – Takes the impact of UK’s future energy scenarios into key strategic directions for network development, identifying the needs for network expansion and the opportunities for smart grid techniques to drive costefficiency and deliver new services. It considers the enablers for change, including the necessary development of commercial and regulatory frameworks

  • DC Injection: Investigation into the corrosion effects of DC on DNO networks with specific emphasis on assessing the impact of DC flows in the neutral conductors and providing evidence that a max of 20 milliamps as per British Standards is sufficient.
