New South Wales is the largest electricity region in the NEM by demand, and its generation mix reflects a fleet in transition. Black coal-fired power stations (Eraring, Bayswater, Vales Point and Mt Piper) have traditionally supplied the majority of the state's electricity, often generating 70-90% of total output during overnight and early morning periods.
Solar generation has become a significant contributor during daylight hours, with both large-scale solar farms and rooftop installations reshaping the midday supply profile. The combined effect of utility-scale and distributed solar regularly pushes coal generation down during the middle of the day, creating the characteristic "duck curve" pattern visible in the generation data.
Wind generation from farms across the state provides variable but increasingly material output. Gas-fired generation, while a smaller share of the mix, plays a critical role during evening demand peaks when solar output drops to zero and dispatchable generation is needed to fill the gap.
NSW’s generation mix is dominated by black coal (Eraring, Bayswater, Vales Point, Mt Piper) overnight, with solar reducing coal’s share significantly during daylight hours. The live fuel-type breakdown is shown above.
Combined utility-scale and rooftop solar can supply a large share of NSW demand during the middle of the day, creating the "duck curve" pattern visible in the live generation-mix chart above.
Gas-fired generation is a smaller share of the NSW mix but plays a critical role during evening demand peaks, when solar output drops to zero and dispatchable generation is needed to fill the gap.
gridIQ refreshes the NSW generation mix from AEMO SCADA and ASEFS rooftop-solar data every 30 minutes, matching the underlying generation-mix ingest cadence.
