Expenditure for Large biogas and biomethane for injection has exceeded its expenditure threshold (set out in the regulations). The growth for large biogas and biomethane is 1857% – the higher threshold for degression is 150%. The total scheme expenditure threshold has also been exceeded, however there was no degression for the previous degression. There will therefore, be a degression of 15% to the tariff for this technology. The degression will come into effect on 1st January 2019.
