Abstract For the solar power plants unsteady power generation is one of the main drawbacks, which must be taken into account. The hydrogen-air energy storage gas turbine system is considered in this paper for the Yakutsk region in Russia. This place with no centralised electrical grid has enough solar insolation level to supply with the power the settlement of several households with the average power consumption of 3 kW. The calculations show that 52 photovoltaic panels of the specific type are optimal number from the power balance data. It is supposed that in the months with the surplus of solar power the system works in generation mode and in the other months in storage mode. Also some reserve is planned for the supply during night in the storage mode by the gel batteries. After that the volumes and masses were determined for the reservoirs containing air, hydrogen and oxygen for the energy storage. The air reservoir for the compressed air energy storage (CAES) has the biggest volume 121 m 3 according to the calculations. The gas turbine (GT) of 5 kW suits the system in the power generation mode. The special hydrogen-air combustion chamber is required for the GT unit.
