UK ICP | High Voltage Infrastructure for EV Charging | Leading The Charge For Your EV Solutions

Location:

Turney Street, Nottingham

Completed:

EV Charging Infrastructure, HV Connections, Substation Installation

Client:

Nottingham City Transport Limited

Stakeholders:

National Grid Electricity Distribution (NGED)

In line with their commitment to sustainable transport, Nottingham City Transport Limited (NCT) is preparing for the rollout of electric vehicle (EV) chargers at their Turney Street depot. To power this transition, NCT has requested a total capacity of 1.8MVA at each of two separate substations on-site: Substation No.1 and Substation No.2.

HV Point of Connection & Supply Strategy

NGED has identified and provided two HV Points of Connection (POCs), located at the outgoing terminals of two new circuit breakers to be installed at Sneinton Primary Substation. These circuit breakers, which NGED is responsible for installing, will act as the source points for the new HV supplies.

Infrastructure Works & Equipment Installation

To deliver the required power, the following strategy was implemented:

Two new 11kV circuits were installed from the circuit breakers at Sneinton Primary directly to the Turney Street site over 1Km
These circuits were terminated at Schneider RN2d Ring Main Units (RMUs), each paired with a MU2d metering unit, located at the newly constructed Substation No.1 and Substation No.2.
The substations were interconnected via a loop, providing network resilience. An open point will be introduced between them, as instructed by NGED, to ensure proper ring configuration and protection.
All electrical equipment were housed in GRP (Glass Reinforced Plastic) substation housings, designed to include a separate metering area
Substation plinths were constructed in line with NGED specifications

Civil Works & Land Requirements

Both substations will be located on land provided by the client.
Prior to construction, full legal searches will be conducted to confirm land ownership, including for the cable routes feeding each substation.
All legal consents and easements must be secured before any site work begins.

Key Consent Areas

Two critical areas had been identified where special consent was required due to infrastructure crossings:

Railway Bridge – Manvers Street
Canal Crossing – London Road / Meadow Lane

These areas involved third-party assets and was carefully coordinated, legally reviewed, and approved the before construction can commence.

Summary

The project represented a key milestone in Nottingham City Transport’s shift to cleaner mobility solutions. With coordination between the client, NGED, and third-party stakeholders, the successful delivery of this high voltage infrastructure enabled the seamless installation of EV chargers, supporting the city's move toward a greener future.
