Brockman Battery Grid Connected

Scope of works

Network studies, design and installation of 2 x 1.3 MVA / 2.5 MWh Tesla Megapacks and the associated electrical infrastructure required for successful connection to the grid. The BESS solution will be utilised in the EvoEnergy electricity grid for load management and FCAS services.


  • ACT's largest privately owned grid connected battery energy storage system.
  • Software Integration including SCADA overview control screen, dashboards, reports, alarms and financial estimation.
  • The HV and LV relays on either side of the transformers are set to protect the transformer and downstream network from three phase and single line faults.
