Something is very amiss with the QLD data. A better site for exploring composition of generation is https://opennem.org.au/energy/qld1/ https://opennem.org.au/energy/qld1/. That said, the result is about right for CO2 intensity, if a bit high. Also the market operator has their own data for CO2 intensity https://aemo.com.au/en/energy-systems/electricity/national-electricity-market-nem/market-operations/settlements-and-payments/settlements/carbon-dioxide-equivalent-intensity-index https://aemo.com.au/en/energy-systems/electricity/national-e... . General comment - Victoria tends to have the worst electricity supply in Australia in terms of CO2 per kWh (brown coal vs black coal elsewhere)
