Decmil and joint venture partner Balance Utility Group were awarded a contract to supply, install and maintain a fully functional, utility scale Battery Energy Storage System (BESS) connected to Western Power’s 33kV distribution network.

The scope of works included:

  • Integration studies;
  • Detailed design;
  • Supply;
  • Construction;
  • Transport to site;
  • Site preparation;
  • Installation; and
  • Commissioning and servicing of the system after commissioning.

Perenjori is supplied by a 33kV long rural distribution feeder. In recent years, Perenjori customers have experienced lower reliability of supply than most customers within the Western Power’s network. The Battery Energy Storage System (BESS) will alleviate the poor reliability of supply experienced by customers in Perenjori.

Delivering solutions.

We are committed to outstanding project management and delivery regardless of the scale or the intricacy of the work.
