Tasmanians will soon be able to choose their electricity retailer, with the government opening the retail market from January 1 next year.
Mr Green said that he believed that recent electricity price rises experienced by Tasmanians will be a thing of the past.
"We are progressing some of the biggest changes we have seen to our electricity industry and it's all about delivering real benefits to households and businesses," he said.
Mr Green will table the legislation next month, removing Aurora's monopoly in Tasmania.
"The sale of Aurora's customer base will begin mid-year allowing customers to be transferred to new retailers for the start of competition," Mr Green said.
"People will benefit from more retailers in the market competing for their business and offering the lowest possible prices and better service."
However, Mr Green said that only 1000 customers a month will be allowed to change retailers for the first 12 months.
Mr Green said he expected to see electricity prices in Tasmania flatten out while continuing to rise in other states as they try to keep pace with their respective energy demands.
"The reforms we are undertaking will place further downward pressure on prices so we won't see the sorts of increases we've seen over the last five years," he said.
"I am confident the price rises we have been seeing will be a thing of the past."
Mr Green said that existing concessions for pensioners and low-income earners will not be affected by the reforms.
"We are also introducing a new rebate for medical cooling for customers who need air conditioning, taking over responsibility for the Salvation Army's hardship program and no interest loan scheme and maintaining the life support discount," he said.
Mr Green also confirmed the Tasmanian Economic Regulator would be given more powers to set the wholesale price of electricity to encourage new retailers to enter the market.
The government decided to transfer the Tamar Valley Power Station to Hydro Tasmania, effective from June this year.
