To ask the Scottish Government what discussions it has had with (a) the National Energy System Operator, (b) ScottishPower Energy Networks, (c) Scottish and Southern Electricity Networks and (d) the UK Government regarding the disparity in transmission impact assessment thresholds between Scotland and the rest of Great Britain.
The Scottish Government engages regularly with Ofgem and NESO to ensure transmission infrastructure delivers for Scotland. This includes exploration of the TIA threshold, and consideration of the impact that this has on energy users in Scotland.
The most recent discussions on TIA thresholds took place with Scottish and Southern Electricity Networks on 4 February 2025. Joint discussions with UK Government, National Energy System Operator and Scottish Government officials took place on 6 February 2025. Officials also plan to discuss this when they next meet with Scottish Power Energy Networks representatives on 11 March 2025.
Officials also attend NESO’s Connections Process Advisory Group and Connections Delivery Board meetings where the TIA threshold was discussed. Membership of these governance boards includes representatives from across industry, including TOs, together with Scottish, Welsh and UK Governments and Ofgem. Notes of these meetings can be found via NESO’s website: Search | National Energy System Operator.
