In PA, we have the PUC, utilities have to present a request for increasing rates to them. That's natural gas, electricity etc. Some regions have odd grandfathered in deals that skew rates and limit competition despite the opening of retail between producers/generation & consumers. Never got an explanation how that was allowed, guess a legally binding deal that has no expiration.....
I think the major problem with that question is that, the former act wasn't "picking winners" for us when there was an established alternative that already met our needs, unlike today..
