replyThat's the theory. Others in this thread are reporting the reality.
replyIn practice, any profit-making enterprise will not want to miss out on the income they were previously getting, so will find other times and charges to load it onto. Also, they know some people will specifically choose an energy plan that seems to give them something free, so it's easy to take advantage by increasing the prices they pay less attention to.
As far as line-items on an invoice are concerned, power always seemed egregiously overpriced, and the infrastructure costs seemed wildly understated.
replySo, maybe this is a correction?
