Automated and Electric Vehicles Bill (Second sitting)

Debate between Scott Mann and Stephen Kerr

Committee Debate: 2nd sitting: House of Commons
Tuesday 31st October 2017 Public Bill Committees

[Stephen Kerr]

Q You do not see legislation playing a part in this?

Robert Evans: At this stage I would say that was not necessary.

[Scott Mann (North Cornwall) (Con)]

Q A couple of my questions have already been answered. One was on the car-to-grid technology and the other one was on peak capacity. I want to ask the National Grid this: does your grid mirror some of the main arterial roads that run through the country? How effectively could you put your grid capacity into locations? I am firmly of the view that we should not necessarily assume that we want all the charging points to be in current service stations—there might be opportunities outside the existing ones—so how easy will it be for you to deliver that with your current grid locations?

Marcus Stewart: The high voltage network does mirror parts of the motorway network, but not all of it. There will be locations where there is a clear opportunity to build a connection for high voltage to supply charging, and there will be other locations where it is just not that simple. It has to be looked at on a case-by-case basis. Some of the options around that are maybe connecting at a lower voltage tier but using onsite storage, so you are not taking too much stress from the grid in one go. You are managing exactly the same as a petrol station does today, where it fills up a tank of petrol under the ground and feeds it to the cars as they need it.

We have talked to different developers and people who are looking at those kinds of options, and we describe it as a sort of mosaic of different charging routes out there. One of them could be high voltage input, with 350 kV of charging, backed up with a megawatt-scale battery to minimise the connection to the grid and that impact.
