This project involved the delivery of a new 6MVA 11kV metered connection at Arriva’s Croydon bus depot to support the transition to electric bus operations. All works were designed and constructed in full compliance with UK Power Networks standards, within a live and highly constrained operational environment.
Arriva London required a new 6 MVA 11kV metered connection to support their transition to electric bus operations at the Croydon depot. All works were delivered to UK Power Networks (UKPN) standards.
Completed detailed design for 11kV installation, including RMU with NVD functionality and associated metering equipment.
Excavation and reinstatement of the HV cable route from the RMU location up to the Point of Connection joint bay, in line with the agreed cable route.
Provision and installation of two 11kV HV cables in a dual-duct arrangement from the point of connection joint bay to the RMU base and onward to the private transformer.
Supply and installation of the GRP enclosure and construction of a reinforced concrete base to UK Power Networks (UKPN) specification.
Installation and commissioning of the 11kV metered RMU, metering, protection settings and associated switchgear and emergency tripping facilities.
Coordination with UK Power Networks (UKPN) for Point of Connection, disconnection, energisation, and commissioning.
All works took place within a live Arriva bus depot, requiring careful coordination with ongoing bus movements, depot access and operational constraints. Safe segregation of construction areas and continuous access for vehicles were critical throughout the project.
The project required 105m of dual-duct HV mains installed in both footway and carriageway, involving NRSWA compliance, parking bay suspensions and Section 50 notices. Works had to avoid existing underground utilities while maintaining public footpath and road access on Brighton Road and Napier Street.
Design and construction required careful planning around the integration of cable ducts within a constrained depot environment while ensuring future access for maintenance and metering equipment.
Project sequencing was heavily dependent on design approval, legal consents for adoptable network assets and timely coordination for energisation and commissioning.
