en.Wedoany.com Reported - SeriEnergy's energy storage power station project in Bulgaria has completed commissioning and successfully connected to the local grid, transitioning from the delivery and installation phase to commercial operation. This marks another smart energy storage project implemented by SeriEnergy in Eastern Europe.

The project has a total installed capacity of 10MW/31MWh, utilizing seven units of SeriEnergy's Star Series 5MWh containerized energy storage system. The system adopts a modular design and highly integrated architecture, offering advantages in site adaptability, transportation, installation, and future expansion, enabling rapid deployment and flexible scheduling from equipment arrival to initial operation. During the grid-connection commissioning phase, the project team collaborated with the grid operator to complete the 72-hour charge-discharge test required by the grid company, with all design parameters meeting grid specifications.

The project is equipped with SeriEnergy's EMS energy storage management system, enabling deep collaboration with local electricity traders to assist in analyzing peak-valley price spreads and demand changes for ancillary services such as frequency regulation and reserve. The system formulates charge-discharge and bidding strategies in the day-ahead market and automatically adjusts in the real-time market based on electricity price changes and grid commands. This intelligent scheduling model allows the energy storage asset to simultaneously capture peak-valley arbitrage and ancillary service revenues within the same period, forming a triple revenue structure when combined with local government subsidies.
