EO Provides Turnkey Electrification Solution for Go-Ahead London at Northumberland Park Bus Garage
Following Transport for London’s (TfL) award of a fully electric contract to Go-Ahead London for Route W15, its Northumberland Park Garage required overnight charging infrastructure to support 12 additional zero-emission e-buses.
01. Project Scope
The project required:
End-to-end delivery of the LV charging equipment, beginning with trenching and connection to existing on-site infrastructure.
All electrical and civils works for the existing power supply connection, feeder pillar and associated LV equipment [12 x 80kW and 88kW chargers and Armco barriers and fixings].
Commissioning and connecting to the charge point management system (CPMS) and back office through existing BYD software and Cloud. Plus, certification and on-site training for Go-Ahead London colleagues.
02. Project Summary
EO’s role in the project:
EO provided consultancy and guidance for the installation programme of the charging infrastructure and supported Go-Ahead London and other partners on the site design and layout.
Following the design phase, as lead contractor EO worked closely with the Go-Ahead London project team, taking responsibility for project management of the civils and electrical installation works.
Individual elements installed (Hardware / Software):
Phihong 88kW and BYD 80kW chargers installed in the garage for overnight charging.
Services provided (Maintenance /Aftercare):
EO provided CAT6 cabling between the new chargers and the onsite BYD communications hub, allowing all 12 chargers to be connected to the existing on-site BYD back-office and charger management system. This also enabled load management alignment to the power available on site.
03. Key Activities Undertaken by EO
Liaison with the charge point manufacturers.
Full project management responsibilities for the installation programme [EO engineering delivery and onsite management team].
Acted as principle point of contact and liaison with the Go-Ahead project team [EO Account Manager].
All variation works for a cable replacement and the charger commissioning process.
Whilst one of the first projects undertaken for Go Ahead London by EO Charging, it laid down a benchmark for price, quality and delivery. It has seen EO deliver more projects for Go Ahead London and become a preferred supplier.

04. Key Challenges & Learnings
At the time of order, the chargers purchased [as specified and requested by Go-Ahead London through Phihong in Taiwan] were only available with 5m cables. This proved to be too short due for the eBus parking and charging layout.
EO was able to arrange with Phihong for an order of additional 7.5m cables and managed the cable replacement once they were delivered to site.
EO also managed liaison with Phihong to commission the chargers, as well as to provide operational training for Go-Ahead London personnel, which was delivered through the EO engineering team.
