In the UK, hundreds of small green gas plants in the UK are set to close by 2031 with the loss of 2 terawatt hours of clean electricity to the grid – enough clean electricity to power around 500,000 homes. The closures have been revealed in a survey of members undertaken by the Anaerobic Digestion and Bioresources Association (ADBA) – the organization representing green gas in the UK. The shutdown will take place over the next few years as old support schemes for green gas end, and operators are unable to justify maintaining and replacing worn-out equipment like combined heat and electric power units (CHP).
ADBA has mapped out the number of green gas plants that will come off support schemes like the Feed-in Tariff (FITS) and the Renewable Obligation Certificates (ROCs) over each year for the next ten years as the schemes end.
