Campaigners are urging councillors to heed their views before making a decision on a windfarm that will be visible from the north’s busiest road.
RWE Innogy want to construct 20 turbines between Tomatin and Farr, adjacent to an existing windfarm.
The proposals for the Glen Kyllachy project will be decided by Highland councillors on Tuesday – two months after they initially discussed the plans.
Proposals for the 360ft turbines, which will be visible from the A9 Inverness to Perth road, went before the south planning applications committee in June, but councillors deferred their decision amid concerns about the standard of the visualisations provided by the developer.
Members of the committee will now visit the site on Monday ahead of their meeting.
The proposals have split the community, with 35 letters of support and 29 objections being lodged with Highland Council.
Supporters of the application said the Glen Kyllachy proposals would not impact on local residents as it would use existing infrastructure from the Farr windfarm during construction.
They also suggested that the development would be good for employment and would be a benefit to the local area.
But both Strathnairn and Strathdearn community councils objected to the application.
Pat Wells, coordinator of campaign group Save Strathdearn said there were major concerns about noise from the site, and about the changes to the way water would drain off the hills into the River Findhorn.
She added: “We maintain that this planning application should not have been processed to the point of determination by Highland Council because the visualisations provided, including the revised ones, fall far below the council’s own excellent standards for visualisations for wind farm developments.
“For these reasons and numerous others we and others have detailed in our submissions to Highland Council, we hope the committee members will refuse the application.”
A spokeswoman for RWE Innogy said: “We look forward to demonstrating to the planning committee on Monday that the proposed scheme has been carefully designed to minimise impacts on local residents, drivers on the A9, visitors to the area and the Cairngorms National Park.”
