The proposed works to be carried out will be the installation of Electric Vehicle Charging Infrastructure to all 320 parking bays within the underground car park. This infrastructure will consist of a centralised Load Management System, along with what can be described as ring-main cabling to all bays in the car park. This allows for a simplified and consistent installation of individual Electric Vehicle Charging Points into the parking bays, as and when required by individual residents.
The works also consist of a new Wi-Fi network to be installed within the car park. This is required for the Pay As You Go functionality that the EV Charging Units will utilise, so that costs for energy consumed through the units is paid for by the resident that is connected to the system.
January 2022 update
Due to the complexities of the project, Kings Chelsea instructed Building Design Consultants who undertook an electrical energy review and feasibility report on the proposed charger installation project. They were required to inspect the car park to ensure there was sufficient space for the new cabling and to look at the condition of the existing switchboards that are planned to be used. Kings Chelsea provided a letter of authority to speak to UK Power Networks (UKPN) on its behalf, with a view to making an application for the power upgrades that are necessary for this project.
Our Building Design Consultants have reviewed the proposals in more detail, and when budget costs has been provided by UKPN we will know the scope of works needed to provide a tender package for the scheme for Section 20 purposes. Following UKPN site visit and confirmation of how the additional power will be provided, our consultants will then be able to specify a tender package.
April 2022 update
The additional kVA required for all the proposed charging infrastructure to be installed at Kings Chelsea is c828 kVA.
UK Power Networks visited Kings Chelsea on 17 March to undertake an inspection of the current electrical infrastructure and we are currently waiting for UKPN to confirm that there is sufficient capacity in the High Voltage network for this project. It was confirmed by UKPN that Kings Chelsea should not need a new substation.
