Tidal Stream Generators

Tidal stream turbines

These are already in place already in some parts of the estuary. They have minimal ecological impacts, but produce only a tiny fraction of the energy that a Barrage would produce.

Some kinds of tidal stream turbines could be placed now in the Severn, and relocated when the Barrage is in place, although in some locations their power would be unaffected by a barrage.
