PRESS RELEASE: ADBA Welcomes Extension of RHI Tariff Guarantee Deadline

ADBA Welcomes Extension of RHI Tariff Guarantee Deadline

  • Deadline for tariff guarantee extended to 31st January 2021 by BEIS
  • Major campaigning win for coordinated ADBA and industry efforts


After an intensive campaign on behalf of the anaerobic digestion industry, ADBA has welcomed the Department for Business, Energy and Industrial Strategy’s extension of the Renewable Heat Incentive’s tariff guarantee deadline for another year, to 31st January 2021.

Due to delays caused by political uncertainty, the existing 2020 deadline was not working for the AD industry, with ADBA members highlighting that construction and connection times did not sync up with the Government’s deadline – potentially leading to developments being abandoned, stymieing investment in anaerobic digestion and biogas projects.  

The Government recently proposed boosting the amount of green gas in the grid, and ADBA has been calling for tangible policy support from Ministers to encourage this. Extending the deadline by another year will help bring certainty to the industry and give projects breathing space to be completed and connected in time to qualify for the tariff guarantee.

Commenting on the news, Charlotte Morton, ADBA Chief Executive said:

“I am very pleased that Ministers have listened to ADBA, our members and the wider biogas sector in implementing this extension to the tariff guarantee deadline. The existing timeframe was simply too tight for some of our members to complete and connect projects, leaving them at risk of missing out on being eligible for the scheme. We will continue to work with Ministers on support for our sector to encourage more green gas to grid, but this is an extremely welcome step.

Further support for our industry is vital even after this extended deadline, both here and abroad. We need to act fast to address climate change, and AD has the ability to help reduce global emissions worldwide by over 10%.”
