New South Wales Carbon Intensity

New South Wales Grid Carbon Intensity

New South Wales is the largest electricity region in the National Electricity Market by demand. The grid's carbon intensity is primarily driven by the output of black coal-fired power stations including Eraring, Bayswater, Vales Point, and Mt Piper, which contribute the bulk of baseload generation. When these plants are running at high capacity, NSW's grid intensity typically sits between 0.6 and 0.9 tCO₂/MWh.

Daytime solar generation — both rooftop and utility-scale — is steadily reducing the midday carbon intensity profile, while wind farms across the state contribute variable low-emission generation. Interconnector flows from Queensland and Victoria also influence the effective emission intensity, particularly during periods of high renewable output in neighbouring regions.

For organisations with operations in NSW, tracking real-time grid intensity enables time-matched Scope 2 emissions accounting and supports load-shifting strategies that reduce both carbon footprint and electricity costs.
