Azerbaijan is stepping into a new phase in the energy sector, APA-Economics reports.

Large-scale Battery Storage Systems (BESS) have been initiated for the rapid development of renewable energy sources (RES) in the country.

Azerenergy is creating Battery Storage Systems with a total capacity of 250 megawatts and 500 megawatt-hours at the 500-kilovolt Absheron substation near the capital and the 220-kilovolt Agdash substation located in the central part of the country. Currently, necessary construction work is being carried out on site, and work is underway to manufacture and deliver the elements on order. The application of systems of this scale will be the first not only in Azerbaijan but also in the entire CIS region.

It has been noted that the creation of Battery Storage Systems is extremely important for increasing the stability of the energy system, frequency stability, reducing interruptions in RES, compensating for active power shortages, meeting peak loads, smoothing the load schedule during sunset hours, and restoring the energy system from zero in case of an accident. The implementation of these systems will not only strengthen Azerbaijan’s energy independence but also ensure the reliable operation of our energy system in parallel and island modes with the synchronous zone of the neighboring country.

It was reported that AzerEnergy is currently implementing a large-scale program to integrate 2 Gigawatt solar and wind power plants to be created in the country by 2027 into the network. Within the framework of the program, in addition to the application of energy storage technologies, one of the country’s largest substations – the 500/330 kV “Navahi” Energy Hub – is being built to serve as a main network junction, from which 500 kV and 330 kV high-voltage transmission lines are laid to various directions across the country. Comprehensive works are being carried out to improve digitalization and grid management.
