  • Distribution Innovation

  • Scottish and Southern Electricity Networks are constantly seeking to improve our understanding of the challenges facing the distribution network in Great Britain, and to find ways to overcome these challenges to ensure security of supply and value for money as Britain moves to a low carbon economy.

    A number of our projects benefit from external funding, which you can read about in the Funding Mechanisms page.

    We actively share the results and methodology of our research with all distribution network operators (DNOs) and stakeholders – why not sign up for our Quarterly Newsletter and stay informed?

    NIA SSEPD 001 DISCERN Knowledge Transfer

    DISCERN focused on the need for enhanced intelligence on a distribution network and the replicability and scalability of solutions across different networks. In addition to direct learning from the solutions trialled at five Smart Grid demonstration sites across Europe, the diverse range of consortium partners enabled the creation of a suite of tools designed to support operators by informing their decisions on the development of networks that will provide high security of supply for the future.

    Expected outcomes -  Studies and research directly relevant to SSEN, is made available for incorporation into both business and innovation strategic thinking. Knowledge relating to a range of Smart Grid sub-functionalities not yet being investigated within the business is made available from other FP7 DISCERN partners. Research and demonstration sites and simulations support decisions on how networks are built, managed and operated. Knowledge of such factors as systems architecture, use cases & Smart Grid Architecture Model (SGAM), semantic models and Common Information Model, is improved across operational and innovation areas of the business, as well as ICT, such that it is possible to take a view on the potential development, relevance and applicability of such approaches within the business from a BAU perspective. SSEN has successfully met all of its obligations as a project partner in the FP7 DISCERN project, and ensured that project outputs do not go against GB interests, specifically those forming recommendations to standards authorities.

    NIA SSEPD 0025 Applied Integrated Vegetation Management (IVM)

    This project seeks to investigate potential improvements of efficiency, safety and environmental impact through the use of Integrated Vegetation Management (IVM). IVM is the practice of promoting desirable, low-growing plant species beneath overhead lines. Combined with occasional herbicide use, they are expected to suppress taller, woody species and so reduce the need for clearance work, reduce the frequency of re-visits; and replace chainsaw and mulcher techniques. IVM offers a safe, environmentally sound, and low cost approach to maintaining the necessary clearance distances.

    Expected outcomes - The success of the project will be defined by the following outcomes: Identification of the extent to which IVM can control trees returning and how effective it is as a tool to maintain regulatory standards around power lines. The project will determine if IVM is a cost effective method in the UK.
