Scottish Power
Scottish Power
Scottish Power is a major UK-based, vertically integrated energy company operating as part of the Iberdrola Group, renowned for its leadership in wind energy and as the first major supplier in the UK to generate 100% green electricity. The company manages energy generation, transmission, and retail across the UK, focusing on sustainability, smart grids, and the transition to cleaner electric transport.
While Scottish Power is actively involved in transmission and network infrastructure—including extensive overhead and underground cabling—specific engagement in HVDC (High Voltage Direct Current) projects is not highlighted as a core focus; its transmission activities in Scotland include significant network management and interconnection, but explicit HVDC project leadership is not a principal feature in its public profiles.
