61.—(1) ROCs are not to be issued in respect of any electricity generated by a generating station from bioliquid unless the bioliquid meets the greenhouse gas criteria and the land criteria.
(2) It is for the operator of the generating station to demonstrate to the Authority's satisfaction that the bioliquid meets the greenhouse gas criteria and the land criteria.
(3) Where paragraph (4) applies to a consignment of bioliquid, a mass balance system must be used for the purpose of demonstrating that the bioliquid meets the greenhouse gas criteria and the land criteria.
(4) This paragraph applies to a consignment of bioliquid where—
(a)the consignment of bioliquid was withdrawn from a mixture containing consignments of bioliquid with differing sustainability profiles, or
(b)consignments of the biomaterial from which the consignment of bioliquid was made were withdrawn from a mixture containing consignments of biomaterial with differing sustainability profiles.
(5) For the purposes of this article—
(a)a mass balance system is a system which—
(i)provides for the sustainability profiles of the consignments of bioliquid or biomaterial added to a mixture to be attributed to the consignments withdrawn from that mixture, and
(ii)requires the sustainability profile attributed to the sum of all the consignments withdrawn from a mixture to be the same, and in the same quantities, as the sustainability profile of the sum of all the consignments added to that mixture;
(b)the sustainability profile of a consignment of bioliquid is information identifying—
(i)the material of which the bioliquid is composed, and
(ii)the proportion that meets the greenhouse gas criteria and the land criteria;
(c)the sustainability profile of a consignment of biomaterial is—
(i)information identifying the material of which the biomaterial is composed, and
(ii)information relating to the biomaterial to be used for the purpose of determining whether bioliquid made from the biomaterial meets the greenhouse gas criteria and the land criteria.
