    An investigation into REZ capacity factors during Victoria’s dark doldrums

    As the grid transitions to much higher levels of renewable penetration, the range of generation outcomes on any given day increases. The worst of these ranges are known as dark doldrums when there is a combination of poor conditions for wind and solar generation, usually a windless day in winter....

    Queensland SuperGrid – Faster than a speeding bullet

    The Queensland Energy and Jobs Plan (QEJP) sets an ambitious goal to deliver the Queensland SuperGrid. The SuperGrid is the future electricity system aiming to deliver consumers clean, reliable, and affordable power. As part of the plan, all publicly owned coal-fired power plants are intended to be retired by 2035....

    The Quest of the Ring: Will the Sydney Ring of Power unlock commercial viability of renewables?

    With the development of Renewable Energy Zones (REZs), the need for transmission augmentation arises to unlock the transfer of energy from Renewable Energy Zones to major load centres. This may subsequently increase the commercial viability of renewable generators within the Renewable Energy Zones, for example, by reducing plants’ technical curtailments...

    Australian Chart of the week | Energy is neither created nor destroyed; it just transitions

    In April, the NSW government opened consultations on “specific urgent and mechanical policy details” on regulations needed to implement its Electricity Infrastructure Roadmap released late last year. The Roadmap aims to unlock 12GW of new renewable energy capacity from selected Renewable Energy Zones (REZs) with an additional 2GW in storage...

    Australian Chart of the week | NEM wind generation: Do birds of a feather flock together?

    With a growing expectation that coal plants will face early retirement, this week’s ‘Chart of the week’ examines the correlation between different wind patterns in the various identified Renewable Energy Zones in the NEM. As would be expected, there is a tendency of high correlation within the individual states, where...

    Australian Chart of the week | Now speed up, gas pedal, gas pedal: faster transition for NSW?

    Last month, the NSW government issued a call to renewable developers to respond to a Registration of Interest to develop a pilot Renewable Energy Zone (REZ) in the Central-West region of the state. This REZ – with an estimated worth of $4.4 billion in private investments - is expected to...
