Question to the Department for Energy Security & Net Zero:

To ask His Majesty's Government which Accelerated Strategic Transmission Investment projects they expect to be completed by 2030.

While TOs are responsible for delivering Accelerated Strategic Transmission Investment (ASTI) projects, Ofgem plays a key role in scrutinising delivery plans, setting the regulatory requirements and monitoring performance (including completion dates), against agreed outputs and milestones. As the independent regulator, Ofgem holds TOs accountable for the efficient and timely delivery of ASTI projects and can investigate potential non-compliance where delivery falls short of regulatory requirements. Government monitors the progress of transmission projects required to meet our goal of clean power through regular engagement with industry and regulators.
