Find out what to do (before your work commences) when working near underground electric cables 33kV or higher.
What to do before work commences
- Complete a Dial Before You Dig (DBYD) enquiry If the DBYD plans show underground cables with voltage 33kV or higher, go to Step 2. If not, refer to Working Near Overhead and Underground Electric Lines (WP1323) (PDF 813.8 kb).
- Request our plans of underground powerlines Complete and submit our online Request for detailed plans form.
- Submit preliminary works plans for us to review Complete and submit our online
Request for review of preliminary works plans form. All proposals must comply with WP1323 (PDF 813.8 kb). If the preliminary plans are acceptable, no further action required. If the preliminary plans require further work, go to Step 4.

Important information about risks
A person conducting a business or undertaking at a workplace must ensure, so far as is reasonably practicable, that no person, plant or thing at the workplace comes within an unsafe distance of an underground electric cable. This includes ensuring that all risks are assessed by your designer or constructor.
Work near energised electrical assets is considered high risk. Specific activities that can increase the risk include but are not limited to:
- entry into the powerline backfill below the protective cover strips, bricks or equivalent (typically installed approximately 100mm above cables)
- removal of flowable fill backfill
- excavation beneath the underground cable.
If your proposed work includes any of the above activities, we recommend that an Energex rated Transmission Civil Contractor from our PCP125 panel is engaged to carry out work and/or assist with risk assessments and development of work methods.
