The Central-West Orana (CWO) REZ, designated as NSW's pilot zone, spans approximately 20,000 square kilometres in central NSW, located between Wellington, Dunedoo, and Merriwa, with Dubbo at its center. Formally declared in November 2022, it achieved a significant milestone by becoming the first REZ in Australia to win planning approval in June 2024. Construction of projects within the zone commenced in late 2024, with operations anticipated to begin by 2028. This REZ has an intended network capacity of six gigawatts by 2038 and will initially feature three energy hubs, with potential for a fourth.

The Hunter-Central Coast (HCC) REZ is located in the Hunter Region, encompassing Newcastle and its surrounds, and extending to the northern areas of the Central Coast, specifically between Muswellbrook and Newcastle. Formally declared in December 2022, this REZ has an initial intended capacity of one gigawatt (GW) of renewable energy generation. This capacity is expected to increase over time, particularly with the retirement of coal-fired power stations, the repurposing of mining land, and the growth of offshore wind energy. The Hunter-Central Coast REZ's relatively lower initial capacity of 1 GW, when contrasted with its strategic location in a coal-intensive region and its explicit link to coal plant retirement and offshore wind development, highlights its role in facilitating a "just energy transition". This REZ is designed not just to add new energy capacity but also to repurpose existing energy infrastructure and leverage the local skilled workforce, ensuring economic resilience in a historically coal-dependent area.

The Illawarra REZ, formally declared in February 2023, is set to become New South Wales's first urban Renewable Energy Zone, strategically located in the Illawarra region south of Wollongong. It has an intended network capacity of one gigawatt (GW), with significant potential for growth driven by emerging industries such as green hydrogen and green steel manufacturing. This REZ is designed to leverage the region's unique characteristics, including existing major energy, port, and transport infrastructure, as well as a skilled workforce. A key aspect of its scope is the integration of consumer energy resources, such as rooftop solar systems, home batteries, and community-scale batteries, with plans to utilize spare government land and commercial roof space to minimize impacts on surrounding communities and the environment.

The New England (NE) REZ is located in the Northern Tablelands region of New South Wales, centered around Armidale. This zone is poised to be NSW's largest REZ, with a proposed capacity of eight gigawatts (GW) of generation. While currently "Under Procurement" and in the early stages of assessing new network infrastructure, the first stage of the REZ is expected to commence construction by 2030, with full project completion anticipated by June 2036. The NE REZ has already attracted substantial investor interest, with 80 Registrations of Interest totaling 34 GW of potential renewable energy projects. The New England REZ's substantial 8 GW capacity target, the largest among the NSW REZs, coupled with its strategic proximity to the NSW-Queensland interconnector, positions it as a key enabler for broader National Electricity Market (NEM) stability and inter-state energy trade.

The South-West (SW) REZ is situated in south-western NSW, centered around the town of Hay and stretching from the Murrumbidgee Local Government Area (LGA) in the east to Buronga in the west. This zone was formally declared by the Minister for Energy in April 2024. With an intended network capacity of 2.5 gigawatts (GW) of new renewable generation and storage, the SW REZ has garnered overwhelming market interest, receiving 49 Registrations of Interest (ROIs) representing a total of 34 GW of potential projects, which is more than 13 times its target capacity. In April 2025, EnergyCo granted access rights to four projects with a combined generation capacity of 3.56 GW, including Origin Energy's 1.46 GW Yanco Delta wind farm and Spark Renewables' 1 GW Dinawan Energy Hub. The REZ is anticipated to be supported by key transmission projects such as the 500kV eastern section of Project EnergyConnect (between Dinawan and Wagga Wagga) and HumeLink, with a strategic goal for completion by 2030.
