Our preferred route

While developing the preferred route we considered the Holford Rules, which set out principles for routeing overhead lines, including choosing natural backgrounds rather than sky backgrounds, and using open valleys with wooded areas rather than areas of higher ground. The best performing options were to connect to a point near Carmarthen, with a route through the Teifi valley. This would result in a total route length of approximately 52km. Visual impacts and effects on the community were important to us when we identified this route.
