89% of battery charging from solar
In winter months, grid charging tops up your battery. With the right energy plan, you can charge during off-peak periods at very low rates - or even free.
Monthly averages based on typical weather. Cloudy days and seasonal variation mean some days will need grid top-up to fully charge your battery. Assumes ~35% of daily usage (5 kWh) during solar hours.
South Australia leads the world in renewable energy penetration, making Adelaide an ideal location for batteries that can participate in lucrative VPP programs.
Adelaide is served by SA Power Networks. With 5 average daily sun hours, a well-sized battery system can significantly reduce grid dependence and electricity costs.
Adelaide residents qualify for the Cheaper Home Batteries Program:
South Australia offers up to $2,050 for connecting a battery to a REPS-approved VPP, plus world-leading VPP earnings.
SA has the world's highest renewable penetration, creating extreme price volatility. Wholesale prices swing from -$50 to $15,000/MWh. Smart batteries capture this arbitrage, and VPP programs offer additional income.
SA has mature VPP programs including Tesla Energy Plan, AGL, and Origin offerings. These pay 10-20c/kWh for grid support events, boosting battery returns significantly.
