Some Australians in the country's east will soon be able to receive free electricity for three hours per day, as part of the federal government's Solar Sharer Offer.Starting Wednesday, the scheme is designed to give more households access to solar power when it's most abundant during the day, the scheme will be available to renters and homeowners living in NSW, South Australia and south-east Queensland, all of which are covered by the Default Market Offer (DMO) Eligible households will need to opt in through their energy retailer.Back in January, Energy Minister Chris Bowen said the Solar Sharer Offer was about "making sure we make the most of our huge solar generation"."It will provide direct bill savings for households who sign up and can move their energy use into the zero-cost power period, while also taking pressure off evening peak demand, lowering network and system security costs," he said.On its website, Australia's energy department says households eligible for the Solar Sharer Offer can take advantage of it by planning around the three-hour daily window.It suggests running larger appliances during the free-power period "where it is safe and practical to do so"
