"attacking electrical infrastructure is a war crime" is quite a woolly and interpretable thing. It's not blanket, there are questions of purpose and proportionality. If, for example, you strike a single civilian substation because by doing so you take out the power supply to a critical defence radar and are then able to attack an otherwise defended military target, then it's hard to argue that's a war crime. Any more than bombing civilian infrastructure like roads and railways. Doing it as part of a deliberate campaign of terror whose main purpose is to harm and intimidate civilians is probably a war crime, although it's very easy to fig leaf it if there's any way that attacking the infrastructure impedes war production directly. Doing it proportionately in retaliation is less likely to be.
