Battery Energy Storage System
The Battery Energy Storage System (BESS) consists of battery-to-grid converter, rack-mounted batteries, battery management system, control system and fire suppression system. For most applications li-ion batteries are the preferred choice and Freqcon co-operates with several tier-1 battery manufacturers. The BESS comes either as a containerized solution for outdoor deployment or in multiple cabinets for indoor installation.
Respecting all relevant grid code requirements the BESS allows the operator to provide a number of grid support services and harvest multiple value streams:
| Fast Frequency Response (FFR) | Providing FFR to stabilize system frequency |
| Short Term Operating Reserve (STOR) | Providing STOR to balance intermittency of renewables |
| Peak Shifting | Shifting peak generation to peak demand |
| Energy Arbitrage | Trading wholesale power to benefit from price fluctuations |
| Voltage Support | High dynamic reactive power control to stabilize voltage |
| Reactive Power | Providing reactive power to reduce network losses |
| Black Start Capability | Providing active power to the system after shutdown |
| Capacity Provision | Providing peak-time capacity to avoid reinforcement costs |
