South Australia’s Rooftop Solar Breaks Demand Record
Rooftop solar energy in South Australia has once again surpassed the 100 per cent grid demand threshold, reaching a peak penetration of 107.5 per cent of state demand on a Sunday afternoon. This achievement marks a significant milestone in the state’s renewable energy journey, following a similar breakthrough on New Year’s Eve in 2023. While not a new record, as the record was set last month at 112.9 per cent, this event is noteworthy amidst the ongoing debate surrounding the future of renewables in Australia.
The increasing prominence of technologies such as rooftop photovoltaic (PV) systems, household batteries, and electric vehicles (EVs) is reshaping the energy landscape. With the fossil fuel industry intensifying its efforts, supported by media outlets like Murdoch media, the role of household assets in the grid is becoming more pronounced.
Key Highlights
During the recent rooftop solar peak, the Australian Energy Market Operator reported a decrease in operational demand to minus 45 megawatts. Despite this, emergency measures such as deploying big batteries or curtailing solar output were unnecessary. South Australia managed to export approximately 658 MW of capacity to Victoria, with minimal reliance on battery storage. The total renewable energy contribution stood at 136 per cent of grid demand, with only 82 MW of flexible fossil gas utilised to ensure grid stability.
Any potential interventions, indicated by a Minimum System Load event, would likely be triggered by network constraints. The successful management of the grid during this period underscores the state’s ability to balance supply and demand effectively, even amidst high renewable energy penetration.
