The UK Government has announced a ban on new internal combustion engine (ICE) car sales from 2030 (originally 2040). Which is quickly followed up with hybrid cars in 2035 and a new set of building regulations (Part S) has been published, dictating the number and type of electric vehicle charging facilities for all new builds and major renovations. The building regulations were updated to include regulations: 44D to 44K which were laid on 15 December 2021 and came in effect on 15 June 2022.

As Graham Thompson set out in his blog post Is the grid ready for electric cars?, Electric Vehicle Charging (EVC) comes with major implications to the national grid which it can’t currently handle. So with the 2022 energy crisis gripping the economy, the question is, could this put people off having electric vehicles all together?

In fact, the 2022 energy crisis may have some positives - one being that it could help to show people how crucial and important the energy we use in our homes and business really is. How many of us just plug in without thinking or leave our TVs on standby without consideration?

Maybe 2022 is the turning point and could be dubbed “the big switch off” because it is forcing us to think differently about our energy use. Forcing us to turn off electronics and unused items of equipment to lower the energy demand on the grid. Maybe then we will have some of the spare capacity required to power all our vehicles. This is only one solution that could help to provide some of the power, but where will the rest of the demand come from? More work and research is needed over the coming years to ensure the UK’s electricity grid can cope.

If we are going to hit the UK’s EV targets, then newer EVC technologies are going to be needed. These include:

  • Smart Charging
  • Demand sharing and energy management
  • Vehicle to grid and battery storage
  • Open protocol payments
  • These technologies will help to drive forward the markets whilst ensuring we have power when we need it and where we need it. Have a look through the Cundall Electric vehicle charge point design guide for further information.

So, as we consider the way forward and how we ready the grid to handle electric vehicles in the near future, I ask you to consider the following:

  • How can you reduce your electricity use?
  • How will you adopt the new Part S?
  • What sustainable technologies can we use to generate electricity for the future?
  • What can the grid do to support EVC?
  • How can we “the construction industry” ensure that we have power “when we need it, and where we need it”?
