That's partly a result of having 50 states writing laws for themselves instead having all statues living under federal laws for everything. The line between what is acceptable to be regulated by federal laws and what is not is something I, not being a lawyer, have never studied. Power and water type utilities does feel like it might be something that could benefit from same rules/regulations every where, but basing regulations on feelings is probably not the best bit of logic

Exactly. Think how much more efficient our government could be if we had one centrally planned government instead of 50 sovereign states. Sometimes I wish I could move to the USSR.

For the most part power grids are federally regulated. The exception is Texas because they are self-contained and don't cross state lines

States rights is not why there are issues with the power grid

EDIT: I should add, states DO also regulate electric utilities but generally that is around local issues like charging rates to customers. the bulk electric system (transmission and generation) is largely the domain of the Federal Energy Regulatory Commission
