PART 8 Additional RHI capacity

76 Additional RHI capacity
1 Paragraph (4) applies where the Authority accredits additional RHI capacity which is first commissioned less than 12 months after the date on which the original installation was first commissioned.
2 Paragraph (6) applies where the Authority accredits additional RHI capacity which is first commissioned 12 months or more after the date on which the original installation was first commissioned.
3 In this regulation “additional RHI capacity” means a plant which is—
(a) first commissioned after the date on which an accredited RHI installation (“the original installation”) was first commissioned;
(b) uses the same source of energy and technology as the original installation; and
(c) supplies heat to the same heating system as that of which the original installation forms part,
but does not include any capacity which is added to an accredited RHI installation which is a shared ground loop system.
4 From the date of accreditation of additional RHI capacity to which this paragraph applies, the tariff for both the original installation and the additional RHI capacity is the relevant tariff based on the sum of the installation capacity of the original installation and the additional RHI capacity, and—
(a) in respect of heat generated by the original installation, determined in accordance with regulation 59 as at the tariff start date of that original installation; and
(b) in respect of heat generated by the additional RHI capacity, determined in accordance with regulation 59 as at the tariff start date of that additional capacity.
5 Where the date of accreditation of the original installation is before 30th April 2013, periodic support payments in respect of both the original installation and the additional RHI capacity shall terminate with the tariff end date of the original installation.
6 Where this paragraph applies—
(a) the tariff for the original installation shall continue to be the relevant tariff for that original installation;
(b) that tariff shall be determined in accordance with regulation 59 as at the tariff start date of that original installation;
(c) the tariff for the additional RHI capacity shall be the relevant tariff based on the sum of the installation capacity of the original installation and the additional RHI capacity; and
(d) that tariff shall be determined in accordance with regulation 59 as at the tariff start date of that additional RHI capacity.
7 All additional RHI capacity must be metered so as to enable the heat generated by such additional capacity and used for eligible purposes to be distinguished from the heat so generated by the original installation.
