Not so sure. There have been all kind of wars in the past 10-15 years, and they were pretty much conventional. Bombs, armies, attacks, and so on.

No high tech wizardry needed...

Not to mention, why even have things like power stations and other infrastructure reachable over the internet in the first place?

I wrote on the subject of cyber warfare and the vulnerability of our nation's utilities first in 2015. At that point, a single malicious actor had gained access to a water treatment plant in Chicago that had no air-gap. They were able to cripple a system by turning a key portion on and off until it burnt out. In 2016, a water treatment plant was targeted in an attack which released high levels of treatment chemicals into the water supply. There is an exceptionally high risk of damage.
