J5 Super Grid Transformer Refurbishment

J5 Super Grid Transformer Refurbishment The United Kingdom Atomic Energy Authority would like to invite suppliers who are interested in this requirement to attend a scheduled site visit, prior to a tender exercise being released for the above requirement. Values listed below are an estimate, and the UKAEA are currently undertaking cost exercises alongside this notice, in order to build upon our current estimates and scope development prior to conducting a tender exercise. Interested parties should contact us via the below link in order to arrange attendance at our site visit.

Please use the attached site visit request form and return to us via the EU Supply link below. Scheduled Dates: - Wednesday 26th August, 9:00am Further dates are available on request, as well as further visits to be arranged during the tender period. Outline Scope of Requirement: This project concerns the strategic life-cycle management of Super Grid Transformers SGT1A, SGT1B, and SGT1C, located north of the J5 Substation.

These critical assets are currently integrated into the 400kV National Grid network and primarily operate in a parallel configuration to ensure grid stability and redundancy. As these assets approach their fifth decade of service, this project represents a shift from reactive maintenance to a formal Asset Life Extension (ALE) Program. By addressing latent defects and obsolescence during the 2026-2027 shutdown, this scope of work aims to "reset" the aging clock of the SGTs, ensuring their continued reliability and operational integrity for a projected further 10 to 15-year life cycle.
