Katy has written to the Scottish Government's minister for Enterprise, Energy and Tourism, Jim Mather, urging him to extend the standard 28-day public consultation period.
She said: "I feel 28 days is an incredibly short timeframe for an application which would have such a huge impact on the local community.
"My constituents have already been denied the chance of consultation when the plans were added to the National Planning Framework without any say from the public.
"People must be allowed to give their views. Extending the consultation period would allow more time for people to engage with the process and to properly examine the final application Ayrshire Power submits."
