NSW and federal Coalition MPs say they will oppose the plan by ACT Environment Minister Simon Corbell to give 20-year government-backed contracts to developers whose projects have been stalled by uncertainty.

A statement given to The Canberra Times on Friday said the loose coalition would ''fight'' the ACT's decision to boost investment in renewable energy projects. But Mr Corbell said he was shocked at the misinformation being peddled.

He was scathing of claims power prices would skyrocket. ''I think there's a lot of misinformation about renewables and, in particular, how the ACT's policy is going to work,'' he said.

''I'm shocked that local and federal members representing the region would be opposed to jobs and investment in their region.

''The development of wind farms in NSW will only occur if they are approved consistent with NSW planning laws.

''Household costs will on average remain $1000 less per annum than equivalent costs in Queanbeyan and that really does demonstrate that the ACT is implementing a plan which is both affordable and achievable.

''Obviously, elected representatives are seeking to reflect concerns in their communities, but equally, I think it is incumbent on them to engage in those discussions based on the facts and based on the context in which the national electricity market operates.''

Landowners with ridges suitable for wind farms receive thousands of dollars each year for allowing installation of the huge turbines. Member for Hume Angus Taylor, who organised the coalition, said the ACT's ambition to have 90 per cent of its power from renewable energy within six years was ''green

policy gone mad''. ''First casualties will be Canberra businesses and Canberra homes,'' he said. ''I challenge Simon Corbell to admit that wholesale electricity prices will triple under his plan. ''We'll go knocking on their [Canberra businesses] doors with an open invitation to come across the border to avoid the power bills.''

Mr Corbell hosted a meeting on Thursday of interested parties, where NSW parliamentary secretary for renewable energy Rob Stokes congratulated the ACT government for ''bold and innovative'' policies on renewable energy. But John Barilaro, Nationals state member for Monaro, challenged Mr Stokes' support for the scheme to buy power from NSW, describing it as unfair.

''I'm sick and tired of NSW being ACT's junkyard,'' Mr Barilaro said. ''The ACT's policies come at the expense of NSW landowners, it's simply not acceptable.

''Regional and rural communities are strongly opposed to wind farms - without broad community support for these developments, they should never be approved.''

Mr Barilaro recently called on the state government to halt approvals of NSW wind farms until the federal government reviews the renewable energy target.

The Abbott government blames a mandated target for renewables for driving up electricity prices.

Yass Valley mayor Rowena Abbey said communities in the southern highlands were ''really angry'' about wind farm projects.
