The necessity to heat air in greenhouses, to water planted cultures and soil requires a colossal amount of heat energy especially under low ambient temperature. To obtain heat the major domestic greenhouse households use boiler stations where original utility product (gas, coal etc.) is burnt only in order to get heat energy for heating. The supplier of electrical energy for electrical supply of greenhouse process equipment (pump and ventilation equipment, conveyors etc.), as a rule, is a territory energy service company. It is of no secret that power supply lines and switchboard equipment becomes obsolete for years of operation. But even high electricity tariffs, which in recent years have grown in times, and apparently will continue to grow, do not give guarantees to the greenhouse complex owner that at some point he is not going to face a de-energized economy. The long absence of electricity and heat supply and, therefore, the inability to perform the process may lead to a significant reduction of harvest, disease or even death of plants.
