Electricity Supply and Reliability Check Up

In this section

The NSW Government released the NSW Electricity Infrastructure Roadmap (the Roadmap) in November 2020, which is legislated under the Electricity Infrastructure Investment Act 2020 (EII Act 2020).

The Roadmap coordinates investment in new transmission, renewable generation, storage and firming infrastructure to ensure NSW has an electricity system that provides affordable, clean and reliable energy for everyone.

Independent Check Up

The independent Electricity Supply and Reliability Check Up (the Check Up) was commissioned to help the NSW Government understand how the energy market and policy landscape has evolved since the Roadmap was released. The Check Up recommended practical steps to keep the NSW electricity system transition on track, and is available here (PDF, 4.34 MB).

The NSW Government considered the report, and the recommendations made, and published its response here (PDF, 456 KB).

Progress on the Check Up

As at 31 December 2025, 44 recommendations have been completed and an additional 6 are underway.

Key outcomes include:

The Roadmap has been designated as a strategic priority of the NSW Government to support whole-of-Government implementation.
December 2023: the Minister for Energy directed the Energy Corporation of NSW (EnergyCo) to focus on clear priorities, including delivery of the Central-West Orana Renewable Energy Zone, Waratah Super Battery, and Hunter Transmission Project.
May 2024: the NSW Government secured an agreement with Origin Energy to extend operating Eraring power station until August 2027. In January 2026, Origin Energy announced it intends to operate Eraring until April 2029.
June 2024: NSW Parliament passed the Energy Security Corporation Bill 2024 which established the Energy Security Corporation as an NSW statutory corporation.
July 2024: A formal governing board was established for EnergyCo.
November 2024: the Renewable Energy Planning Guidelines for wind and solar energy generation and transmission infrastructure were finalised and published.
March 2025: the NSW network hosting capacity opportunities map was launched on the NSW Spatial Digital Twin. The map highlights where connections opportunities may exist for renewable generation in the distribution network.
April 2025: EnergyCo delivered the first round of grants under the NSW Government’s $128 million Community and Employment Benefit Program in the Central-West Orana Renewable Energy Zone.
May 2025: the Biodiversity Conservation Regulation 2017 (NSW) was amended to introduce a new offsetting pathway for major energy transition projects in NSW. The amendment allows proponents of eligible projects to enter into Strategic Offset Delivery Agreements (SODAs) with the NSW Government.
October 2025: The NSW Government published the Transmission Planning Review Final Report and its formal response. The Review made 15 recommendations to optimise transmission planning arrangements for NSW.
