Normally its not advisable to hack shearwall. It may affect the strength of the wall. Even if its just for plugs as it reduces the concrete cover protecting steel.
Just because there's power points on shearwall doesn't mean it can be hacked because the construction sequence is to lay conduit for those power points BEFORE concreting take place.

Its better not to hack any of shearwall as it acts as column & beams supporting the whole freaking building. Maybe its a bit exaggerating, but you'll never know how it'll affects the wall.
