58A.—(1) This article applies to a generating station which—
(a)is accredited;
(b)is offshore;
(c)generates electricity from wind; and
(d)in the case of a generating station accredited before 1st April 2011, has added registrable additional turbines on or after that date.
(2) The operator of a generating station to which this article applies may apply to the Authority in writing for one or more wind turbines to be registered under this article in relation to the generating station.
(3) For each wind turbine to which the application relates, the application must—
(a)identify the location, or the proposed location, of the wind turbine; and
(b)specify the total installed capacity of the wind turbine.
(4) Following receipt of an application meeting the requirements of paragraph (3), the Authority must register the wind turbines to which the application relates if the Authority is satisfied that—
(a)where the station was accredited before 1st April 2011, the wind turbines are registrable additional turbines;
(b)where the wind turbines are registrable additional turbines—
(i)the date of receipt of the application was no later than 5 years from the date on which registrable additional turbines were first added to the station; and
(ii)the Authority has not registered other registrable additional turbines in relation to the station on more than 4 separate occasions;
(c)where the wind turbines form part of the accredited capacity of the station—
(i)the date of receipt of the application was no later than 5 years after the date on which the station was accredited; and
(ii)the Authority has not registered other wind turbines forming part of the accredited capacity of the station on more than 4 separate occasions; and
(d)where the wind turbines form part of the accredited capacity of the station and no other wind turbines have been registered under this article in relation to the station, the total installed capacity of the wind turbines to which the application relates is at least 20% of the accredited capacity of the station.
(5) The Authority must notify the applicant in writing of its decision on an application to register a wind turbine under this article.
(6) In providing written notification under paragraph (5), the Authority must specify the date on which the registration of the wind turbine is to take effect.
(7) For the purposes of this article, the date on which a registrable additional turbine is added to a generating station is the date on which the registrable additional turbine is first used to generate electricity.
(8) In this article, in relation to a generating station “accredited capacity” means the capacity of the station as accredited.”.
