Section 33(2) does not prevent an order under section 3 of the Transport and Works Act 1992 (c. 42) from authorising the carrying out of works consisting of the construction or extension of a generating station that is or (when constructed or extended) will be a Welsh offshore generating station.

A “Welsh offshore generating station” is a generating station that is in waters in or adjacent to Wales up to the seaward limits of the territorial sea.

If, by virtue of subsection (1), an order under section 3 of the Transport and Works Act 1992 authorises the carrying out of any works, development consent is treated as not being required for the carrying out of those works.
