Perenjori network battery

Perenjori: From blackout town to energy innovation crown

Blackouts have been all too common in the small Western Australian town of Perenjori.

The Mid West town sits at the end of a long stretch of powerlines which are exposed to a range of environmental factors.

A problem anywhere along this long line could cut power to the town.

Thanks to a 1MWh network battery installed on the outskirts of town Perenjori is now the first town to trial a backup battery supply on the Western Power network. The battery was commissioned in August 2018 and the community is already beginning to experience tangible benefits.

Western Power has been working with Balance Utility Solutions to design and deliver the Battery Energy Storage System. The system is comprised of lithium-ion batteries with an inverter. It kicks into gear instantaneously if the town loses supply from the main electricity network.

The 1MWh network battery will act as a backup power supply for the town and will eliminate up to 80% of outages, based on the town’s power outage history.

Town residents and businesses may still experience power outages, however these will be after the network battery is exhausted and a series of notifications will enable them to plan for the outage.

Insights gained from this trial are helping us determine how we can deploy network batteries effectively to other communities.

Perenjori customers can opt-in to receive SMS notifications when:

  • A fault on the line has triggered the network battery to start working
  • The network battery is running low and you’re likely to experience a power outage
  • The fault has been fixed and you’re receiving power from the main line again
