Cheap energy rates are further threatened by the government's aim to reduce the environmental impact of carbon capture and storage (CCS) plants, according to the Daily Express.
More coal-fired power stations are likely to be needed to plug the gap between the imminent decommissioning of several older plants and new nuclear reactors coming online, but funds to develop CCS technology could be passed to the consumer.
The cost could come to nearly £10 extra per year on the average domestic energy bill, which could result in more people falling into fuel poverty.
Jonathan Stearn, an energy expert at Consumer Focus, told the paper: "Tackling climate change is essential. But much of the cost is likely to be passed on to consumers through higher energy bills. This could stretch the lowest income households further and plunge many into fuel poverty."
All the major energy companies raised their prices through 2008 and adding £10 to bills each year could result in nearly two million more households becoming fuel poor.
Energy firms received intense criticism for failing to reduce prices during the winter months earlier this year.
