This paper aims to present a comparative analysis of biogas electricity deployment in EU countries over the period of 2010–2017. The analysis shows that the deployment of biogas electricity is mainly linked to the moment of the shift in the support framework, the maturity of tenders and the feasibility of long-term objectives. With 200 incentives in place the EU has created favourable conditions to support biogas electricity. Manure and waste are the main feedstocks of biogas electricity in the EU that receive the highest incentives. However, the recent shift towards capacity market mechanism has had an adverse effect in the deployment of biogas electricity. The way in which the biogas is currently valorised, has not been very effective in some EU countries. We found that the EU average growth rate of biogas electricity over 2016–2017 dropped 4 times compared with 2014–2016. Plans/targets have been very supportive in the fast deployment of biogas electricity. Nevertheless, a clear post 2020 picture for renewables is still missing in several EU countries that are risking lagging in biogas electricity deployment. The future of biogas is been seen promising on the upgrade to biomethane as a sustainable input for environment and economy.
