Looking at the National Grid's plans for new powerlines between Twinstead and Ipswich it looks as though the closest route,No 4, goes some way to the east of Waldingfield Ward. Those interested can see more information than is available in the press on the National Grid's website.
Route 4 looks to be a less likely route in any event than 1 or 2 which closely follow the existing pylons that pass well to the south of Sudbury.
For once we seem to have escaped the march of progress and depradations of modern life!
