BARNSLEY East MP Michael Dugher is calling for measures to tackle high price energy bills, such as forcing power companies to put people over 75 on the cheapest tariffs.
Mr Dugher also wants to scrap Ofgem and replace it with a tough new energy watchdog.
It would have the power to force suppliers to pass on price cuts when the cost of wholesale energy falls.
The MP says energy companies should be required to pool the power they generate and make it available to any retailer, putting downward pressure on prices.
Mr Dugher says Barnsley families are facing record fuel bills while energy companies are enjoying huge profits.
If people over 75 were put on the cheapest energy tariff, he says, they could save up to £200 a year.
"The economy has flatlined for two and a half years. On average real wages are down £1,700 since 2010 and energy bills have risen by over £300.
"This has been one of the coldest springs on record and rising energy bills are putting real pressure on the budgets of many in Barnsley."
