Battery Energy Storage (BESS).

Standalone and co-located storage, containerised or built-up. Sizing, grid behaviour and energy management decide whether it earns revenue and supports the grid.

What We DeliverTalk to an Engineer

Types We Engineer.

No two Battery Energy Storage Projects are the same. Here is what changes from one type to the next.

Standalone Grid-Scale

Storage connected directly to the grid for trading, balancing or grid Services.

What We Focus On
  • Duty-cycle based sizing
  • Grid code performance in charge and discharge
  • Dedicated substation and protection

Co-Located with Renewables

Storage sharing a connection with a solar or wind plant.

What We Focus On
  • Shared connection capacity and export limits
  • Coordinated control with the plant
  • Protection across both systems

Behind-The-Meter

Storage at an industrial or commercial site for peak shaving and backup.

What We Focus On
  • Load and tariff-based sizing
  • Integration with plant switchboards
  • Islanding and transfer behaviour
