Electricity generation

Queensland currently has an installed generation capacity of around 13,520 megawatts (MW), although some generators may be operating infrequently or not at all because of lower wholesale electricity market prices or higher gas prices, in the case of gas-fired generation.

The National Electricity Market (NEM)

The NEM is a wholesale market supplying electricity into the interconnected grid powering most of eastern and southern Australia. Under the management of the Australian Energy Market Operator (AEMO), generators and retailers trade electricity into a pool where supply is dispatched (sent out into the grid) to meet demand on a near real-time basis.

More information on the NEM can be found on the AEMO website and in the Australian Energy Regulator’s annual State of the Energy Market report.

Generation outside the NEM

The interconnected grid does not extend to every city, town or community in Queensland. These areas rely on generators operating outside the NEM to send out electricity into isolated networks (networks not part of the interconnected grid).

Isolated networks are typically small in area and have relatively few customers, with the exception of the Mount Isa‑Cloncurry network in the state’s northwest. The small isolated networks are generally powered by diesel or other liquid-fuelled generators while the Mount Isa‑Cloncurry network is powered by gas-fired generation.

Ownership

Government-owned corporations have a stake in about 65% of the state's generation capacity, although the number of partially or fully privately-owned power stations has increased over the past decade.
