In Nizhne-Bureiskaya HPP, the first results of work on solar power generation are summarized. Now it is the only hydroelectric plant in Russia that produces electricity not only thanks to the usual units, but also due to the operation of solar panels. Special photovoltaic cells are located in the vicinity, the surrounding hills and even in the water area of the reservoir. Our reporter discovered that solar activity can rival the energy of water.
– Here is the first floating solar power plant in Russia, implemented as part of the Nizhne-Bureyskaya HPP solar power project, consisting of 140 photovoltaic modules installed on a floating base, with a total capacity of 54 kW.
Vyacheslav Sladkevich, chief engineer at Nizhne-Bureyskaya HPP, knows all about solar power generation. Even during the construction of a hydroelectric power plant, special photovoltaic cells were installed here as an experiment. Then the first batteries were installed on the hill next to Bria. The idea turned out to be successful. Now there is not one site near the dam, but five such sites.
“We have more than 200 sunny days a year. This is very powerful solar energy. As part of the project, we have installed additional equipment that allows us to check the number of sunny days and the energy potential of the Amur region. This means that it has been confirmed that we have a very bright and strong sun in our area , and that solar power generation is capable of developing in our region,” says Vyacheslav Sladkevich.
The total capacity of local solar power plants is just over a megawatt. This is much less than what is produced by each of the four hydroelectric units. But it is enough to cover up to 100% of the special needs of the Nizhne-Bureyskaya HPP. The saved electricity is sent to the Unified Power System of the Far East.
Nizhne-Bureyskaya HPP solar power plants are an example of rational use not only of natural resources, but also of the territory. For example, in this place during the construction of the hydroelectric power station there was a temporary camp. After all the works were completed, the site received a second wind and the photovoltaic cells were placed over the area of two football fields.
In total, approximately 3.5 thousand PV modules were installed. Its total annual production is one and a half million kilowatt-hours. Floating power station is a universal thing in general. If necessary, they could be quickly delivered to any settlement – whether by water or dismantled by land or air – and provide an independent supply to a small village for several days. It all depends on solar activity and the time of year.
“For me, I conclude that when implementing new projects it is necessary to create stations with the possibility of adjusting the seasonal angle. That is, in the summer period we work with the maximum angle in summer – at an angle of 35, and in the winter period we raise a steeper angle so that the sun provides the maximum angle of attack on the photovoltaic cells and maximum output,” Vyacheslav Sladkevich.
The Nizhne-Bureiskaya HPP plant can rightly be called the first hybrid power plant in Russia. Moreover, the most environmentally friendly sources of energy are water and the sun. The expertise of Amur power engineers will be expanded to other solar regions of the country. The experiment turned out to be a success.
