EPCOR is planning an ultra-fast EV charging site in Edmonton, but what caught my attention is the tech behind it.

Instead of the chargers just pulling maximum power all the time, EPCOR is using smart grid technology (DERMS) that coordinates the chargers with the electricity grid. The idea is to allow very fast charging while managing how power is drawn so it doesn’t overload local infrastructure.

Curious if anyone working in utilities or grid planning here has thoughts on how this actually works in practice? This seems to be new here, but same/similar tech seems to be in use in other areas of Canada, so perhaps some of you know more about this. Anything that can help combat the 'our grid can't support EVs' crowd is a welcome addition.
