Promoting biogas production to generate energy is associated with several EU policy initiatives such as increasing the output of electricity and thermal energy, energy independence, and the reduction of GHG emissions. Besides, one of the topical problems is the increasing amount of organic waste and residue from agriculture, industry, and households, thereby making waste management, recycling, and waste reduction one of the government policy priorities. Therefore, energy production from biogas that forms in the fermentation process of various (including agricultural) wastes provides environmental, social, and economic gains, and it plays a significant role from both bioeconomic and energy policy perspectives. Owing to the support mechanisms for biogas production in the EU and Latvia, 38 biogas production units with a total capacity of 42.93 MWel operated in Latvia in 2013; 32 of these units produced biogas from biomasses of agricultural origin. Yet, presently, the expansion of this sector is almost stopped, as obligatory purchases of electricity are not held anymore. In the present paper author reveals risk evaluation results of the biogas production plants that produce biogas form agricultural biomasses. Risk evaluation was made in 2013 and it showed that risks in this sector were mainly caused by the political decisions and arises in the biogas production process.
