Regulation 62 Calculation of subsequent tariffs
Except as provided in paragraphs (2) to (4), in relation to a particular financial year, the subsequent tariff is the tariff applicable to the biomethane produced by the participant or to the accredited RHI installation on the last day of the previous financial year, adjusted by the percentage increase or decrease in the relevant measure of inflation for the calendar year ending with the 31st December immediately preceding the commencement of that subsequent financial year, the resulting figure being rounded.
Where paragraph (3) or (4) applies, the subsequent tariff from the date on which these Regulations come into force until 31st March 2018 is the relevant tariff set out in Schedule 6.
This paragraph applies where—
a participant produces biomethane for injection or an accredited RHI installation generates heat from biogas;
the tariff start date is on or after 14th December 2016 but before 1st April 2017; and
the participant has elected to be subject to the requirements in regulation 74.
This paragraph applies where—
an accredited RHI installation generates heat from biomass and has an installation capacity of 1MWth or above; and
the tariff start date is on or after 14th December 2016 but before 1st April 2017.
In this regulation “relevant measure of inflation” means—
if the tariff start date is earlier than 1st April 2016, the retail prices index; and
in any other case, the consumer prices index.
