An increase in electricity bill rebates will be given to seniors, veterans and pensioners in order for the Labor government to retain its generous solar panel feed in tariff.

The Palaszczuk government has announced the increase following a Queensland Productivity Commission Electricty Pricing report.

The government says electricity prices will rise 1.2 per cent annually over the next two years and the electricity rebate will be extended to assist 157,000 low-income families in Queensland.

But the Liberal National Party opposition has accused Labor of dismissing its own electricity price productivity report which would have driven down power costs.

Opposition energy spokesman Michael Hart says a draft report hidden from the public for six months states Labor's policies would cost $10.8 billion in subsidies to solar panel owners.

He is calling on Premier Annastacia Palaszczuk to guarantee power bills won't rise for households or businesses because of her policies "which are driven by a need for Green preferences".
