EVs impact on the grid according to MIT

The boffins at MIT are forecasting that EVs charging with home fast chargers could add the equivalent power consumption of 3 houses to the grid. According to MIT, “Electric cars being sold today can draw two to five times more power when they’re charging than electric cars that came on the market just a couple of years ago.”

Utilities are now prioritizing areas that are seeing a higher proportion of EVs sold as the risk is that failure to upgrade the connectors could lead to more frequent blackouts. The upgrade costs are borne by all ratepayers, not just the EV buyer.

According to a UK National Grid report, peak demand for electricity will add around 30 gigawatts to the current peak of 61GW – an increase of 50%.

It is doubtful whether most governments have factored in the true costs of EVs on electricity markets other than vague commissioned reports that get them to the result their looking for. Then when it’s too late and EVs potentially start crashing the grid then comes all the regulation around when you can charge and the decade of planning required to set up a new back up electricity facility to make up for the shortfall.

Watch it unfold. Governments doing what they do best. Making promises by which time they’ll be out of office when the true costs must be borne.
