Energy Storage & Grid
Battery storage sized through the full energy chain, and the grid studies that prove a plant can connect, ride through faults and be protected properly.
What we do
- 01
BESS sizing
Power and energy sized through the chain from factory acceptance to the point of interconnection: auxiliaries, conversion, transformer and line losses, degradation and augmentation.
- 02
Grid load-flow & short-circuit
Steady-state load-flow, contingency and short-circuit studies at the connection point and inside the plant.
- 03
Single-line diagrams
SLDs drawn from the model and exchanged with common power-system study formats (DGS, CGMES, pandapower).
- 04
Distribution protection
Protection coordination for distribution networks, relay settings and fault location.
- 05
Grid strength & compliance
Short-circuit ratio, reactive capability and grid-code requirements for inverter-based plants.
- 06
Testing
BESS and distribution test plans from FAT through site acceptance to grid-code compliance tests.
Typical deliverables
- 01BESS sizing report with energy chain FAT → POI

Method
- 01
Use case
Arbitrage, ancillary services, firming or backup defined first.
- 02
Energy chain
Usable energy traced from cell to point of interconnection.
- 03
Network model
Plant and grid modelled; load-flow and faults simulated.
- 04
Protection
Settings and selectivity proven, fault location planned.
- 05
Test & accept
Test plans written before equipment ships.
