National Energy Emissions Audit: April 2019

by Hugh Saddler

Welcome to the April 2019 issue of the NEEA Electricity Update, with analysis of the previous month. The Electricity Update presents data on electricity demand, electricity supply, and electricity generation emissions in the National Electricity Market (NEM), plus electricity demand in the South West Interconnected System (SWIS).

In this issue we provide a slimmed down version of the key findings and visual representations, as we look to trial different variations of the Electricity Update.

Key Findings:

  • Continued fall in annual emissions over the past few months has been mainly driven by a large absolute increase in large scale solar generation.  
  • The dramatic increase in grid scale solar generation has contributed to renewables supplying monthly 14-15% of total generation (including rooftop solar) since last November. 
  • There has been a jump in medium (+15kW) to large (+100kW) rooftop solar installations. 
  • Our annual review of seasonal peak demand in each state shows that peak 30 minute (trading interval) demand reached record levels in both Queensland and South Australia, during summer 2018-19. 
  • ‘Baseload’ energy demand at a 15 year low in South Australia.
