Power prices in eastern states are forecast to go down by 10 per cent, driven by an uptick in renewable energy and batteries.
The final Default Market Offer, which sets out the maximum amount retailers can charge on plans, shows price reductions for households and even bigger drops for small businesses.
Some households are expected to save more than $200 a year in their power bills when the offer comes into effect in July.
Household standing offer time-of-use prices will fall by up to 10.7 per cent across South Australia, NSW and Queensland's southeast.
Small business standing offer time-of-use prices are set to fall by up to 20.9 per cent.
The Australian Energy Regulator sets the default market offer as a benchmark for residential and small business electricity bills in NSW, southeast Queensland and South Australia.
