The Highlands and Islands Enterprise (HIE) has challenged the scheme saying that it could make many alternative energy projects unworkable. Connection charges for a large wind farm in northern Scotland will rise from £60,000 a year to £200,000 a year if the changes go through.
"We are meeting Ofgem in a couple of weeks time and issues like charging will be raised," Sandy Cumming, HIE's chief executive, said.
"This is fundamental. We have the resource and it's only fair, proper and appropriate that we have the opportunity to contribute to the energy requirements of Scotland."
