Ofgem threaten to 'break' The Big Six
Their measures require large suppliers and generators to trade fairly with smaller firms or face stiff cash penalties.
Not only that, Centrica (British Gas), E.ON, SSE, Npower, EDF and ScottishPower will have to post the prices at which they will buy and sell electricity up to two years in advance.
It seems Ofgem wants the industry to move to simpler tariffs that everyone can understand and introduce more competition into the market in a bid to lower the prices for customers.
Ofgem's Ian Marlee said that the measures should open up the market. Competition isn't a bad thing, right?
He added: "It's not just requiring the big six to actually post prices up to two years in advance, actually it's also forcing them then to sell at those prices if the independent suppliers want to buy at those prices".
