Western Power – Emergency Solar Management in WA

To maintain the stability of the energy system and support the continued installation of rooftop solar, the WA State Government is introducing emergency solar management.

All new and upgraded solar PV and battery installations with an inverter capacity of 5kW or less will need to be capable of being remotely turned down or switched off in emergency situations.

According to Western Power.

Inverter systems installed on or after 14 March 2022, will need to comply with ESM requirements and means you’ll need to:

  • apply for a new Retailer Reference Number (RRN), and
  • submit a new Western Power Embedded Generation application.

If you’ve recently installed and have submitted a Notice of Completion from Building and Energy, and have yet to submit the Embedded Generation Registration application for your approved system, we encourage you to do so here by 13 March, 11.59 pm. Our team is here for you. If you have any questions, please contact us online or call 13 10 87.
