If you thought incentives were strong for electric vehicle buyers in British Columbia, consider the deal in Norway.

With policies in place that allow EV drivers to collect charging and parking points, avoid certain taxes and take advantage of cheaper or free road tolls, sales of electric cars in the European nation hit an all-time high this spring.

In March, nearly 60 per cent of new cars sold were fully electric.

In total, some 220,000 of Norway’s 2.7 million cars are EVs.

But according to a study ordered by Norway’s power regulator, the increased use of electricity to charge vehicles could come back to smack citizens right where it hurts—their wallets.

State-appointed consultancy Poyry says that with driving and charging habits the way they are now and EV penetration increasing, the Norwegian power grid will be in need of upgrades to the tune of 11 billion crowns (over $1.6 billion) by 2040.

“If nothing is done, charging every afternoon to evening seems most likely,” Poyry’s Norway director Kjetil Ingeberg said in an interview with Reuters. “In that case, the 11 billion … grid cost is paid by all customers.”

Here’s the thing, though: this whole issue could likely be avoided if drivers just made some changes to their EV routines.

According to the Reuters report, “Charging car batteries at night would drop new grid costs to almost zero, while charging in the afternoon and only when batteries are relatively empty would require just above 4 billion crowns ($613,0000) of investment.”

Norway is often the first nation to face such futuristic societal growing pains, so we’ll be watching to see how its smart and tidy people manage the challenge.
