Nicola Sturgeon, the Deputy First Minister, has told the SNP conference that an Independent Scotland would bring about a "real and lasting cut in Scottish energy bills."
"I can announce today that an SNP government in an independent Scotland will remove the cost of energy saving measures and the warm home discount from energy bills. We will provide that funding from central government resources.
"That will mean direct government funding for fuel poverty schemes of at least £200 million per year.
"That money will be spent in a fully joined up way, on schemes designed in Scotland to meet Scottish circumstances.
"And this won't just allow us to deliver our energy efficiency schemes more effectively. It will also save hard-pressed consumers money.
"We estimate that it will cut energy bills by around 5% - or £70 a year.
"Not a short term measure - but a real and lasting cut in Scottish energy bills."
