Apparently the energy retailers can Opt Out of whatever your contracted rate is at any time and there is nothing that can be done about it. This happened to me recently and here is an article that explains the the energy industry is regulated by itself:

In Britain contracts are inforcable but not so here.
BTW gas is not an option for long as the retail gas industry is moving to world spot price for gas and the people getting cozy deals on it at substidised rates are seeing increases already. This is the new area where duel supply retailers like AGL can make more money both ways.
