Tesla and other electric cars drives parts of Norways electric net to its knees

Latest from Norway - electric companies having issues due to too many Tesala's with high power chargers. There are a lot of Tesla's in norway....

Ohh well that was bound to happen. I think London is next for Tesla flicker. :) Uptake here seems to grow fast.

Yeah like who didn't think this would happen ?  ::)

Time to restart some coal fired power stations ?  >:D

Wouldn't help one bit, as it's the distribution net that is overloaded. The energy companies simply didn't plan for this amount of power being consumed way out at an endpoint (aka, house).

What I find really interesting is that they're running into this issue with "only" 4% of the cars in Norway being electric.

I think the electric companies dont plan for anything ever. They are acting like the firefighters.
I'm fighting a different issue at work. Too many solar installations cause the voltage to increase, at some point the inverters have to switch off to avoid overvoltage. This decreases the voltage for others, who can switch on, and they start bouncing on-off until the situation changes. Some people loose 50-100 EUR a year because of this, sometimes even without knowing about it.
Of course instead of replacing the cables with just thicker cables, they want software solution. Great planning. They cannot predict simple things, like: In 5 years we will switch off this powerplant. It takes 5 years to build a new one. When do you need to start building a new power plant:
A) When the lobbyist gives me money
B) After the catastrophic failures start happening
C) Right now? No that cant be right.

There is a strategic system for a country, the power grid. If the grid goes down, GDP goes negative. So it makes total sense, to sell these systems to private operators driven by profit. For example, the USA loses 33 Billion USD every year because power outage. I wonder, if you would spend that money on the power grid, make it redundant and resilient, move it underground where needed, if that would pay back. In a year.

I went to Croatia for a vacation this year, to an island (with a bridge to mainland EU).  3 out of 10 evenings, the power went down for 30+ minutes. Are you kidding me? What is this, early 19 century?

They just did this is Sweden a few years ago, as we had some storms that tore the grid to shreds (I was without power for 5 days. That was fun). Well, at least the "move it underground" part.

Thing is. I doubt they planned for the increase in demand, so if we end up having the same issue as Norway (highly likely), they'd have to dig everything up again to put down bigger cables.  ( I live in a rural area, so putting cables underground is as elegant as digging a ditch, toss in the cable and cover it with dirt )
