Aurora will charge an extra 1.8 per cent on power from today, but a 2 per cent power price decrease is expected on January 1, as a result of electricity industry reform.

Opposition energy spokesman Matt Groom said the government's position on power prices was ``all smoke and mirrors''.  

``The Premier [Lara Giddings] is deliberately misleading people by suggesting that power prices are coming down when in fact they are expected to be increased again from July 1 [today],'' Mr Groom said.  

``The Premier is giving with one hand and taking with the other.  

``The problem for Tasmanians is the Premier appears to be taking more than she's giving.''

An opposition spokesman said the complexity of electricity charges meant many people would pay 3 per cent more from today, and the January decrease was not guaranteed.

A government spokesman said the Independent Regulator had recommended today's increase, which was in line with CPI.

He said Energy Minister Bryan Green was concerned by the opposition attempt to politicise the reform of Tasmania's electricity industry, which is aimed at keeping downward pressure on prices.

He said the opposition supported the government's energy reforms in parliament.

``It is crazy for the Liberal Party to now criticise the fact that power prices are under control and are actually falling,'' Mr Green said.

 ``I challenge the Liberals to say what they would do differently.''

 Mr Green said the Liberals were still trying to mislead Tasmanians by saying they would immediately cut prices by handing back the windfall to Hydro Tasmania from the carbon tax.

``It is complete rubbish because if Tony Abbott happens to become prime minister no windfall will exist anyway,'' Mr Green said.

Mr Abbott has promised to abolish the carbon tax.

Mr Green said the government provided $37 million in last year's budget from extra revenue generated by the price on carbon to limit power price rises.
