The hub is expected to play a critical role in transforming the electricity network in the region.
The approval follows two years of development and consultation with local communities and stakeholders. Perth-headquartered SSEN Transmission highlighted the hub as part of its wider £22 billion investment programme, which contributes to the renewal of the electricity transmission system across Great Britain. The project has also undergone independent review, receiving approval from the National Energy System Operator (NESO) and regulator Ofgem.
Community input played an important role in shaping the project’s final design. Concerns over flooding and visual impact were addressed through drainage planning and screening measures. These adjustments aimed to balance technical requirements with local considerations.
Once completed, the Netherton Hub will host a 400kV substation to support both offshore and onshore electricity generation, as well as a 132kV substation to provide connections for future generation and storage projects by third-party developers.
The site will integrate with broader transmission initiatives. The Spittal to Peterhead High Voltage Direct Current (HVDC) converter station will transmit renewable energy from new generators in northern Scotland to demand centres across the UK. In addition, the Eastern Green Link 3 HVDC converter station will transfer renewable power from northern Scotland to Norfolk and further south.
Supporting infrastructure will include a transmission hall to expand network capacity, a spares warehouse, and an operations base to ensure effective long-term management. With planning consent now granted, construction of the Netherton Hub is scheduled to begin in early 2026.
Alison Hall, director of development at SSEN Transmission, said: “The decision marks a key milestone in delivering UK and Scottish Government energy targets – one that will deliver a new strategic hub for onshore and offshore projects that will be critical to delivering a cleaner, more secure and affordable energy system for future generations.”
The project illustrates the growing importance of transmission infrastructure in meeting renewable energy ambitions. By enhancing grid connections and providing additional capacity, the Netherton Hub is expected to support the transition to a low-carbon power system while ensuring reliable supply.
The council’s approval marks an important step toward strengthening the regional network, with the hub positioned as a key link in connecting northern Scotland’s renewable energy potential to wider markets across Great Britain. With its construction, the project will contribute both to local economic activity and to broader energy security objectives.
