– new offshore generating stations under section 36 of the Electricity Act 1989 (applications are made to the Marine Management Organisation (the “MMO”));
– variations of existing section 36 consents under section 36C of that Act (applications are made either to the Secretary of State or the MMO, depending on who granted the original consent); and

Numerous changes are also made to the existing regime for EIAs, as outlined in the Explanatory Note.
