6 Tesla Superchargers to be included as part of Gridserve’s Electric Forecourt development, officially confirmed today by Gridserve today. Almost certain to be V3 250 kW. I lined up the site plans on Google maps and estimate the Tesla bays will be located at (51.852600, 0.522400).
This has its own thread on TMC: https://teslamotorsclub.com/tmc/threads/gridserve-braintree-status-video.206006/
Also links to planning docs showing the site layout etc. are included in the UK Superchargers thread, e.g. https://teslamotorsclub.com/tmc/posts/4975125/
They are targeting opening November. It’s not clear if the Superchargers are actively being constructed but I’d class this as “under construction”. Looks like a promising deal and Gridserve have planning applications for two further sites in SE England with an expectation that Tesla, as a technology partner, will have charging bays at both.
