I think people are under appreciating how much power running a truck stop with say 20 fast chargers would draw from the grid.

Tesla's new V3 supercharger can pump out 250kw each, so in theory 4 cars would consume a whole MW of power, 5MW to charge 20 cars at a time. Add in the electric semis with 900-1,000kw battery packs to achieve a 600km range, they will draw up to 2MW each to achieve the claimed 30 min charge time.

The new Sheppard gas plant produces 860MW of power. The entire city of Calgary is using 1,050MW right now. If you were supercharging 20 cars and 5 semis at a time you're consuming 1.5% of the total load for the city.

I hope my math is right, I am pretty dumb when it comes to electrical.
