Scottish and Southern Electricity Networks (SSEN) Smart Grid and Network Upgrade
North of Scotland and Central Southern England · Ongoing (e.g., £2bn network upgrade, £29bn investment to 2030) · £2bn (network upgrade), £29bn (investment to 2030 for transmission network) [130, 131]
The judgement call
Account-gated at launchCommitment to substantial investment in network infrastructure to support the energy transition and unlock economic opportunities [131, 136]. - Collaboration with engineering firms and technology providers to enhance network capabilities and resilience [132, 134]. - Focus on smart meters as a key component for managing energy use and supporting network operations [137].
Key engineering challenges
Upgrading and strengthening the network to accommodate increased renewable energy generation and meet net-zero targets [131, 136]. - Enhancing grid resilience and reliability across diverse geographical areas, including rural and remote regions [130, 134]. - Deploying smart meters and integrating them with network operations for better energy management and communication [133, 137]. - Managing significant investment programs to modernize both distribution and transmission infrastructure.
