The ISP forecasts the need for over 125GW of
additional VRE capacity by 2050 to meet demand as
coal-fired generation withdraws¹
Coal generation still accounts for 67% of electricity
generation in the NEM (excluding South Australia)²
More than half of the capacity underpinning this to
exit the NEM by 20301
Gas generators will be essential as they can be
turned on within minutes to support intermittent
renewable energy generation
