Exactly Who is making money from these Energy Price Hikes?

A question on everyone’s  mind at the moment concerns exactly  Who is making money from these Energy Price Hikes. I have watched reports and can’t  seem to get to the bottom  of it. There has been suggestions  that Price Hikes are because  of infrastructure  costs such as pipes and wires but that simply doesn’t  add up. Surely  our taxation system  provided money to develop things like nuclear  power stations etc so why isn’t  the public in control  of these businesses?
