QUEENSLAND's Transmission Network
Our purpose is to connect Queenslanders to a world-class energy future, providing electricity to more than five million Queenslanders and 241,000 businesses.
Powerlink plays a vital role delivering Queensland's world-class energy future.
Through our unique central position in the power system, we are guiding the market to help influence the energy system of the future - one that balances customer needs while transforming to a future comprising a diverse array of generation and storage technologies.
Powerlink’s network serves as the platform for the provision of energy services while maintaining a sharp focus on safety, affordability and reliability of supply for our customers.
Our customers and communities
As well as connecting large generators to end-use customers through the distribution networks owned by Energex and Ergon Energy (part of the Energy Queensland Group) and Essential Energy (in northern New South Wales), we also directly provide electricity directly to large industrial customers such as rail companies, mines and mineral processing facilities.
As a Transmission Network Service Provider (TNSP), we link to the National Electricity Market (NEM) via the Queensland/NSW Interconnector (QNI) transmission line. Most of Powerlink’s network is regulated by the Australian Energy Regulator (AER) under the National Electricity Law and the National Electricity Rules (NER).
