Every Queensland household - all 1.9 million of them - will get a $50 discount on their electricity bills for the next two years.

As the next state election looms, Premier Annastacia Palaszczuk took to the back deck of an old Queenslander in Greenslopes on Sunday to announce a $300 million energy plan, which also includes an ultimatum to retailers.

Premier Annastacia Palaszczuk has announced a $300 million affordable energy plan.

The package includes an "asset ownership dividend" of $50 a year which will be stamped on every household's electricity bill for the next two years, starting January 2018.

It will be paid for using all the dividends from the state's publicly-owned energy companies over the next two years.
