01 / Capabilities

Engineering around your operation.

Scope is defined around the needs, equipment and conditions of each project.

  • Storage management

    BESS charging and discharging, state of charge and energy, availability and operating limits.

  • Power allocation

    Coordination of active and reactive power between blocks according to capacity, availability and constraints.

  • Solar generation

    Coordination of solar production and curtailment when operating conditions require it.

  • Operating modes

    Management of grid-connected, islanded and generator operating sequences according to project architecture.

  • Supervision & historical data

    HMI/SCADA, alarms, events and trends to understand operation and review its evolution.

  • Engineering & integration

    Programming, communications, testing, commissioning and documentation according to the agreed scope.

02 / Solution focus

Secondary voltage and frequency regulation.

A key function in our EMS scope for BESS projects. Integration, operating modes and performance criteria are defined according to each system’s conditions.

Interfaces and responsibilities

What we define with you before execution.

A clear scope reduces integration risk. These points are agreed in writing at the start of the project.

  • Variables and commands exposed by the BESS and inverter manufacturers.
  • Required operating modes and the transitions between them.
  • Voltage and frequency regulation requirements applicable to the system.
  • Relationship with the PPC, SCADA and other existing controllers.
  • Performance criteria and acceptance tests.

How we implement it

Engineering with a clear sequence.
