(Alliance News) - SSE PLC on Tuesday said it welcomes the National Energy System Operator's 'Beyond 2030 Update', anticipating further investment for its SSEN Transmission business as a result.
The Perth, Scotland-based electricity generator said the update details a series of new and upgraded electricity transmission network reinforcements which NESO believes are required to reach the UK and Scotland's energy targets.
SSE said this includes multiple onshore and offshore reinforcements in the north of Scotland, which it said could represent an additional GBP12 billion in estimated further investment for SSEN, its electricity transmission business. SSEN, which is also based in Perth, manages northern Scotland's electricity transmission network.
These are a new 2 GW HVDC link from Aberdeenshire to Lincolnshire and one from the Newmachar area to southeast England, both via subsea offshore cables, and a new 400kV double-circuit line from Greens substation in Aberdeenshire to Harburn in SPEN's network region.
SSE also noted that NESO confirmed the potential need to upgrade the "Dounreay to Loch Buidhe to Beauly 275kV overhead line" with higher-capacity conductors.
It said Tuesday's update builds on NESO's 'Beyond 2030' report from 2024, which "included several new and upgraded reinforcements in the north of Scotland that are now at different stages of the development phase" and "confirmed the need for additional north-south network reinforcements".
SSE said it submitted several onshore and offshore reinforcement options for NESO to assess, "before confirming today's additional reinforcements as the most appropriate solutions."
It said that as the recommendations progress through the development stage, they will be subject to extensive public consultation and stakeholder engagement to help inform potential routes, substation locations and technology choices.
"Progression of these investments will require an appropriate regulatory framework, including early confirmation that SSEN Transmission will be the delivery body, alongside securing all planning and regulatory approvals," it added.
SSE shares were marginally higher at 2,460.00 pence each in London on Tuesday morning.
