At the end of the XX century, during the agrarian reform in the Republic of Sakha (Yakutia), deep organizational, structural and socio-economic changes took place. At present, the foundations of a multi-layered agricultural economy have been created, a wide range of agricultural producers, distinguished by a variety of forms of ownership and management, have been formed, land transformations have been carried out. One of the acute problems is the physical and moral deterioration of the agricultural machinery fleet. From year to year, the availability of machines and aggregates for the mechanization of labor-intensive processes is deteriorating. In the agricultural sector of the republic, in quantitative terms, the share of agricultural enterprises with state ownership is 0.4 %, and private enterprises account for 99.6 %. At the same time, the vast majority of private farms carry out the laborious process manually. Due to the fact that in recent years the requirements for the quality of milk have become stricter, processing enterprises accept milk obtained only by machine. Accordingly, the number of farms decreased, milk yields decreased. It is possible to increase milk yield by organizing summer farms on decentralized agricultural land. To create such farms, it is necessary to introduce the technology of anaerobic digestion of cow manure in bioenergy plants with the conversion of the resulting biogas into electrical energy. There are various technologies in this direction. The use of psychrophilic accumulative technology is justified for use in a decentralized area. It works steadily at ambient temperatures from 5 оС and above, has a low-volume methane tank up to one cubic meter, which makes it affordable to purchase and easy to maintain and operate. At the same time, the conducted biogas accumulates in a gas tank-compressor and is converted into electrical energy through a generator.
