Innovation Funding Incentive
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
- 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.
