Subject to Article 10(1), instead of producing NIROCs pursuant to Article 3, a designated electricity supplier may discharge (in whole or in part) his renewables obligation in relation to a particular obligation period by producing to the Authority in accordance with this Article eligible GBROCs issued in respect of electricity that has been supplied to customers during that obligation period.

A GBROC 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 GBROC for the purpose of the GBRO order under which it was issued a notification in writing identifying the GBROC to be so produced for that purpose and giving its GBROC identifier.

Without prejudice to paragraph (2), the Authority may draw up procedural guidelines for the production of GBROCs under this Article.
