The Authority‘s main objective is to protect existing and future consumers' interests in relation to gas conveyed through pipes and electricity conveyed by distribution or transmission systems. Consumers' interests are their interests taken as a whole, including their interests in the reduction of greenhouse gases and in the security of the supply of gas and electricity to them. Since 2010 the Authority has imposed nearly £100 million in fines and redress levies against energy suppliers, including a £12 million redress levy on E.ON in May 2014, and a £1 million redress levy on British Gas in July 2014.
