12.—(1) Subject to article 15, instead of producing certificates pursuant to article 3, a designated electricity supplier may discharge (in whole, except to the extent of the minimum wave or tidal requirement, or in part) its renewables obligation in relation to a particular obligation period by producing to the Authority in accordance with this article eligible NIROCs issued in respect of electricity that has been supplied to customers during that obligation period.
(2) A NIROC referred to in paragraph (1) shall be regarded as produced to the Authority in respect of an obligation period where, before the specified day relating to that period, the Authority receives, from the designated electricity supplier which is treated as holding the NIROC for the purposes of the NIRO Order under which it was issued, a notification in writing identifying the NIROC to be so produced and giving its NIROC identifier.
(3) Without prejudice to paragraph (2), the Authority may draw up procedural guidelines for the production of NIROCs under this article.
