Artelia – EV Charging Solution – Shell Fenstanton

Back to Case studies

Summary

  • New HV supply of six 150KW rapid chargers
  • Designed, built and installed substation, HV supply and LV terminations
  • Full HV testing and commissioning of substation
  • One of the First Artelia site in Europe using Tritium PKM 150 charge points
  • Works taking place on a live forecourt
  • Working with other contractors in a restricted working area
  • Pre-cast substation base installation utilised

Overview

eSmart Networks were appointed by Artelia to complete an 11kV installation providing a supply for new EV Charging points. This included the first Artelia site in Europe using Tritium PKM 150 EV fast charging points which offer world-class reliability and serviceability.

As part of this project eSmart Networks designed and built a connection to the existing HV network and installed a new High Voltage (HV) substation, including precast bases, and Low Voltage (LV) pillar terminations. All works were completed whilst working within close proximity of local residences and a fully operational filling station.

Challenge

  • The offsite cable route was congested with existing services; therefore, excavation works had to be moved into the carriageway.- Due to the close proximity of gas mains, Cadent Gas needed to be present throughout the works. This required collaborative working and meticulous planning and organisation to keep on programme.
  • To develop a phased programme that was acceptable to both Cadent & the local council. In order to provide safe working conditions, Cadent Gas required eSN to excavate a series of trial holes to ensure we did not affect their existing assets. We worked closely with Cadent Gas on the trial holes whilst also coordinating with the local authority to allow repeated access to the road space.
  • The forecourt was required to remain open and operational throughout all of the onsite and offsite works. The biggest challenge was to ensure continuity of power whilst the new onsite infrastructure was being energised, eSN expertly scoped, planned and utilised back-up generation to allow the site to remain fully operational.
  • A comprehensive site review was undertaken to identify the optimal lay down area for materials and storage facilities. Close cooperation was required with both the council and site staff to ensure the site could be kept clean and tidy and the forecourt operational throughout the works.

Solution

  • To ease any concerns of the local residents prior to the works commencing we established good lines of communication with them by giving notice of dates and details of the work with both letter drops & face to face communication.
  • Effective organisation and timely communication with the DNO/IDNO & local authority ensured we were able to maintain programme and meet the customer’s required live date.
  • Our dedicated project manager liaised closely with the end customer & Arcadis, to notify them well in advance of any disruption to power at the site.
  • We fully leveraged our proactive approach to planning work to push for the live date to be completed in early February 2023.
  • We effectively managed our teams which allowed us to increase supervision, both offsite and onsite, to ensure frequent and clear communication.

RATP Dev Transit London – EV Charging Solution, Westbourne Park Bus Depot Phase 1A

Back to Case studies

Summary

  • New HV supply to 20 80kW chargers
  • Designed, Built and Installed a substation, LV cabling, containment and LV terminations
  • Full HV testing and commissioning of substation
  • Works taking place in a live bus depot

Overview

eSmart Networks were appointed to provide the capability for RATP Dev Transit London to run new electric bus routes from their Westbourne Park depot.  This required the provision of 20 new charging outlets and the infrastructure to power them.

Using knowledge from across the business we were able to implement a scheme that allowed the client to power these chargers from their existing metered supply into the site.  We also gave them the opportunity to have a new connection exclusively for the bus charging supply.

As part of this project, eSmart Networks had to install a new 11kV packaged substation, custom-built LV Pillar and 20no 80kW BYD Chargers along with civils work, fitting of armco barriers and a custom fabricated walkway around the site.

This is the first phase of an exciting development to introduce over 30 more electric buses onto routes in this area. We are delighted to partner with RATP Dev Transit London in their continued electrification of their fleet.

Challenge

  • Installation of chargers, armco and the LV Pillar on a reinforced concrete deck, without penetrating beyond a set amount into the structure.
  • Installation of HV and LV cables along the side of the deck, dropping down safely in containment to the new transformer.
  • Installation of transformer below the deck alongside the site’s haul road.
  • Coordination of works with RATP Dev Transit London to ensure no impact on the live bus depot.

Solution

  • Acceleration of the programme from 12 weeks to 8 weeks.
  • Strong organisation and communication with the client and their operational team.
  • A proactive approach to planning work, pushing for energisation and live date to be completed early Feb 2023.
  • Design and build of new charger foundations to avoid over-penetration into the concrete deck.
  • Sourced an alternative route for containment, when the initial route was deemed unworkable due to third parties.
