The main distribution substation for this supply is J5 substation, located at the north end of Culham Campus. The substation is undergoing a significant upgrade in 2026. The scope is for part of that upgrade. It covers the design, manufacture, delivery, installation, and commissioning of: • A replacement 415V AC Distribution Board, • 3 replacement auxiliary supply cubicles including isolation transformers, • A new 400/33 kV inter-trip panel to transfer trip signals between the 400 kV and 33 kV substations, and • A new 400 kV revenue metering panel capable of metering the 400 kV supply for each of the three Super-Grid Transformers (SGTs). All of the above must be capable of integration with a new IEC 61850 SCADA system. ## CPV classification Electrical apparatus for switching or protecting electrical circuits Electrical machinery, apparatus, equipment and consumables; lighting Electrical fitting work Electrical installation work of electrical distribution apparatus Source Find a Tender (UK) · Notice ocds-h6vhtk-05d5ac-2026-05-21T11:42:48+01:00 [View official notice](https://www.find-tender.service.gov.uk/Notice/ocds-h6vhtk-05d5ac-2026-05-21T11:42:48+01:00) Never miss a tender like this again Get AI summaries, deadline alerts and a bid pipeline for tenders matched to your business.
