Due to the recommendation of the World Health Organization, the standard rate of vegetables consumption for a person per year is 130-150 kg, including up to 15 kg of fresh production during the off-season. To meet these standards in Russia, the construction of greenhouses and greenhouse complexes was sped up. To cultivate the bulk of vegetables in the conditions of protected soil we have mostly used winter greenhouses. At the same time, in terms of the climatic conditions, the main production costs are accounted for energy carriers (up to 60 – 70%). The main consumers of energy in greenhouses are plants’ lighting and creation of the required temperature conditions for plants and soil. Annual increase of rates for energy carriers affects the cost of the greenhouses’ production. To increase the energy efficiency and independence in greenhouse complexes, it is proposed to use installations based on gas reciprocating units (GRU) for the production of two types of energy – electric and thermal. Such installations can run on the natural gas and other types of fuel. The drawback of existing installations is that they are mainly produced abroad or consist of the foreign components. As an alternative, we offer new technical solutions, which were developed and patented in the Russian Federation. What makes these solutions original is that asynchronous generators in the installations are used with various control schemes
