Proponents West Wind Energy were to begin construction of the 64-turbine wind farm late last year.

But general manager Tobias Geiger said the project had been affected by the uncertainty of what the new renewable energy laws would bring.

Mr Tobias said the company needed to ensure the government's scheme set a target high enough to sustain the renewable energy industry long term.

Mt Mercer Wind Farm was approved by the State Government two years ago.

West Wind Energy selected Enercon as its wind turbine supplier and Powercor as the preferred contractor to build the balance of the plant.

Mr Geiger said the planning report for the company's proposed 64-turbine Lal Lal Wind Farm was still being assessed by the State Government.

He was confident of securing investment, despite the economic climate.

He said if the Federal Government's legislation set high enough energy targets, there was no doubt investment could be raised.

Similar to West Wind Energy, Wind Power is also awaiting news of the Federal Government's targets to determine its next step for Tuki Wind Farm.

Community consultant Ross Richards yesterday said the company was finalising the layout of its planning application for its proposed 282-turbine wind farm at Stockyard Hill.

He said it would then be reviewed by the Department of Planning and Community Development before being put on public view.
