The message
from "BAC" contains these words:

Tidal flow has been used to generate electricity on the Rance estuary in
Northern France, I believe.

Pelamis has supplied wave-generated power to the national grid from
Orkney

Perhaps, but as you say, that is wave generated power, not tidal flow
generated power.


I don't know why no-one has yet built a tidal flow power station in the
UK,


Google on European Marine Energy Centre.

IIRC, it didn't include tidal flow generation facilities as built, that was
something reserved for the future, and would require an extension.

It's in Scotland.


In the same sense that the Isles of Scilly are in England, I suppose.
