The article considers the need to ensure reliable power supply to high-tech enterprises, taking into account two location options: near the city or power lines, and in a territory remote from it. The problem of using only one power source for such enterprises is connected to current instability in frequency and voltage changes, as well as planned or unscheduled power outages in the power transmission line network. A variant of an automated power supply system is proposed as a backup source. This includes AC power from an external network and power from a combined wind-solar installation. The study proposes schemes for the joint use of wind-solar installations and external sources for enterprises located near power lines. It further proposes a scheme for the joint use of power lines with recuperators and thermoelectric generators, in those cases when enterprises are located beyond the reach of power lines. The result of this proposal is a constant, high-quality and uninterrupted power supply to high-tech power plants at any time of the year and under any weather conditions.
