David Cameron admitted the Government needed to work "harder and faster" to bring down energy bills ahead of a summit at Downing Street.
The Prime Minister said the at meeting at the Department for Business, Innovation and Skills with representatives of the "Big Six" power firms, consumer groups and regulator Ofgem would discuss how to create a "trusted, simple and transparent" market.
In a joint article with Liberal Democrat Energy Secretary Chris Huhne on the moneysavingexpert.com website, he wrote: "Energy bills have increased by more than £100 for most people since this summer. These price rises couldn't come at a worse time for consumers who are already feeling the pinch from rising petrol prices and the cost of the weekly shop."
The premier said he wanted to focus on "getting people the help they need to reduce their bills in time for this winter". He added: "Our intention is for today's summit to be the start of a much more active engagement with consumers, with us all working harder and faster to deliver an energy market that is trusted, simple and transparent."
"A market that puts the consumer first and gets these energy bills down as much as possible. We are determined that everything that can be done will be done to help people bring their energy bills down."
The summit is expected to consider how better to inform consumers about the potential savings they could make from checking they are on the cheapest energy deal, switching supplier, or taking advantage of subsidised insulation.
The coalition Government is aiming to get on the front foot on energy bills after Labour leader Ed Miliband attacked the "rigged" market in Britain.
Richard Lloyd, executive director of Which?, is among those attending the meeting. "This is an opportunity for the energy suppliers to show they understand how angry people are about rapidly rising prices and bad customer service," he said. "It is also an opportunity for the Prime Minister to show a real commitment to reforming the energy market so that fuel is affordable for all consumers.
Mr Huhne told BBC News: "I'm determined that we have a much clearer, fairer and much more competitive retail market so that consumers can switch more easily with simpler tariffs and get better deals, and so we get new entrants into the market and that's what we're doing with the electricity market reform to bring new competition into the market," he said.
"These companies are not the Salvation Army, they are trying to make profits for their share-holders, and that's important that we in the Government work with Ofgem to make sure that these are genuinely fair and competitive markets."
