UK ends subsidies for small-scale biomass plants, putting poultry-litter power stations at risk

Rule Changes

Renewables Obligation support expires from 2027 through 2037 with no successor scheme planned

Today: Melton warns of plant closures and job losses

Overview

Updated 1 hour ago

Energy minister Michael Shanks confirmed on September 1 that the government will not offer successor subsidies for small-scale biomass generators as Renewables Obligation (RO) support expires. The category covers plants under 100 megawatts, including dedicated biomass, anaerobic digestion, sewage gas, and energy-from-waste facilities. Support begins winding down from 2027 with the last accreditations ending in 2037.

The decision directly threatens Melton Renewable Energy, which runs three poultry-litter plants at Thetford, Eye, and Westfield processing 600,000 tonnes annually. The company has received £649 million in taxpayer support since 2010-11 and says closures and redundancy consultations could begin as soon as December. With no clear alternative disposal route for chicken waste, environmental regulators are watching whether litter ends up in waterways or on farmland.

Why it matters

If these plants close, 600,000 tonnes of UK poultry waste per year loses its designated disposal route, and the country's power supply loses a small but reliable baseline generation source.

Key Indicators

£649M
Total RO subsidies to Melton plants since 2010-11
Combined payments to the Thetford, Eye, and Westfield plants, roughly £43 million per year.
600,000 tonnes
Poultry litter processed annually by Melton
Across the three plants, more than half of Melton's income comes from taxpayer support.
405 GWh
Electricity generated by Melton plants in 2025
Roughly 0.13% of UK electricity demand — modest output for the level of subsidy.
100 MW
Capacity threshold for small-scale biomass definition
All plants below this size lose RO successor support.
2027-2037
Support phase-out window
Different assets reach end-of-support at different points across the decade.

Historical Context

2 moments from history that rhyme with this story — and how they unfolded.

November 2015 - October 2024

UK Coal Phase-Out (2015-2024)

The UK announced in 2015 it would close all coal-fired power stations by 2025, later tightened to 2024. Subsidies and capacity payments were progressively withdrawn, and plants closed on schedule across the decade. Ratcliffe-on-Soar, the last coal plant, shut in October 2024.

Then

No major security-of-supply failures occurred as gas and renewables filled the gap, vindicating the phase-out approach.

Now

Established a template for ending subsidies for legacy generation: announce dates far in advance, hold the line, rely on market signals for replacement.

Why this matters now

The biomass phase-out follows the coal playbook: long-notice subsidy removal, with the government betting the market absorbs the loss without reliability issues.

2015-2026

US Biomass Subsidy Battles (2015-2026)

Massachusetts and other states have spent over a decade debating whether wood-burning and biomass plants deserve clean-energy subsidies. The Massachusetts Senate in August 2026 voted to remove biomass from clean energy standards, arguing lifecycle emissions are worse than fossil fuels for some feedstocks.

Then

Proposed Springfield biomass plant lost its subsidy base, with legislators calling the vote the 'final nail in the coffin.'

Now

A cross-Atlantic convergence on biomass skepticism: governments on both sides treating small-scale biomass as high-cost, questionable-benefit generation.

Why this matters now

The UK decision and Massachusetts action reflect a shared reassessment of biomass's role in decarbonization, though the UK is more focused on cost than emissions accounting.
