The Walney 2 offshore transmission assets, comprising the export cable and associated offshore and onshore substations connecting the Walney 2 wind farm to the onshore grid near Cleveleys/Stanah, were commissioned on 23 August 2011. Ofgem notes that commissioning (hot commissioning enabling energisation) marked the point at which the assets were complete, ready to transmit electricity on a commercial basis, and therefore operational, aligning the end of the construction and interest-during-construction period with National Grid’s Interim Operational Notice on that date.
