Stirling councillors have voiced their unanimous opposition to plans to upgrade hundreds of electricity pylons from the Highlands to central Scotland.
There are fears over the health impact of the pylons
The authority's planning panel rejected the proposal due to concerns about the health and environmental impact.
It backed calls for a public inquiry into the plans and called for a summit involving others opposed to the move.
Scottish and Southern Energy (SSE) said it still believed the application was "robust and appropriate".
Its proposals involve "super-pylons" between Beauly in the Highlands and Denny, near Falkirk.
The largest of the 600 electricity pylons on the 137-mile route would be 65m high.
The line would cross the Cairngorms National Park and pass within sight of the Wallace Monument in Stirling.
Objections have already been lodged by the Cairngorms National Park Authority, Highland Council and Perth and Kinross Council.
Stirling Council wants to hold a summit with these organisations, as well as Falkirk Council, Clackmannanshire Council, the Scottish Environment Protection Agency (Sepa) and Scottish Natural Heritage, to discuss their opposition.
Stirling's planning panel said it recognised the importance of renewable energy, but felt not enough had been done to justify the chosen route.
It said alternative routes and methods of distribution, such as underground cabling, had not been exhaustively investigated.
The panel also suggested approaching SSE to investigate any possible improvements or compromises.
Councillor Charlie McKean, the panel's chairman, said: "There are strong planning grounds to object to this proposal.
"There is also great concern from Stirling's citizens and other citizens affected by the proposed route of the powerline."
