This March 2020 issue of the NEEA report includes data updated to the end of February 2019. Data presented covers electricity demand, electricity supply, and electricity generation emissions in the National Electricity Market (NEM), plus electricity demand in the South West Interconnected System (SWIS). The main trends in the mix of generation and the level of demand for electricity have continued as in the past two or three months.
- In February 2020, grid renewables supplied 19.7% of all generation supplying the NEM grid. When rooftop solar is included, the renewable share increases to 24.3% of all generation, including rooftop solar, in the NEM grid.
- South Australia (SA) has the highest share of rooftop solar in the NEM. This has meant South Australians are annually reducing their demand for electricity from the grid (when so many are getting it directly from their roofs).
- SA is increasing the security and reliability of its electricity grid through its three battery systems (Hornsdale, Dalrymple North and Tailem Bend), virtual power plants being rolled out in Adelaide, four synchronous condensers currently being installed ahead of Summer, the introduction of Wholesale Demand Response next year, and final approvals in 2021 for a new interconnector with NSW.
- The SA Government has an opportunity to package stimulus to improve electricity conservation by ensuring that all air conditioning systems are properly maintained and correctly operated; incentivise heating and cooling improvements to housing stock, particularly the notoriously thermally inefficient private rental properties; and upgrade inspection, certification and enforcement of mandatory minimum energy performance standards for new houses and apartments.
