Question to the Department for Energy Security & Net Zero:

To ask His Majesty's Government what the original estimated completion date was for the new 400kV double circuit Blackhillock-Peterhead project; and what the current estimated completion date is.

Government monitors the progress of transmission projects required to meet our goal of clean power through regular engagement with industry and regulators. Transmission Owners (TOs) are licensed and regulated by Ofgem. While TOs are responsible for delivering transmission 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. Ofgem holds TOs accountable for the efficient and timely delivery of network upgrades and can investigate potential non-compliance where delivery falls short of regulatory requirements.
