Essential Energy is a government-owned electricity network corporation tasked with owning, operating, and maintaining part of Australia’s largest electricity distribution network. It was created in 2011 when Country Energy and Australian Inland Energy and Water were merged. Essential Energy covers an extensive region, providing essential electricity network services to residents and businesses across 95% of NSW and southern Queensland.

🌍 Where Do They Operate?

Mainly over regional, rural, and remote parts of NSW and southern Queensland.

Essential Energy’s network covers around 737,000 square kilometres—a similar size to Germany and the UK combined. This enormous area includes:

• – 95% of NSW and south-eastern parts of southern Queensland
• – More than 1,500 regional, rural, and remote towns

📊 Network Size and Reach

Essential Energy’s network is broad and varied:

• – 183,000 km of over-the-wire powerlines
• – 1.4 million power poles
• – 364 zone substations
• – 139,303 distribution substations
• – Serving over 890,000 customers, from homes through to businesses, hospitals, and schools

Despite having this broad base, the customer density is very low, at the order of 4.86 customers per kilometer of powerline, making maintenance and service delivery difficult.

• – Emergency response 24/7 to power outages
• – Ongoing maintenance and upgrading of network infrastructure
