Queensland Opposition Leader Tim Nicholls has made fresh accusations that government-owned power generators Stanwell and CS Energy have been price-gouging.

Mr Nicholls mentioned the issue several times in his speech to the Liberal National Party state convention on Sunday, and promised to bring it up every day between then and the state election, due early next year.

Energy Minister Mark Bailey has rejected claims the generators had been gouging, saying Queensland has one of the lowest wholesale energy prices in the country.
