Australia trials "sun tax" to manage solar energy exports, encouraging battery use and evening grid support.

In Australia, a new "sun tax" or two-way pricing system is being trialed to manage excess solar energy generated during peak daylight hours. This affects one-third of households with rooftop solar, historically exporting 75% of output to the grid. To combat this, economist Nicki Hutley recommends investing in household batteries and vehicle-to-grid charging. Smart meters, now being rolled out across the country, will help optimize energy usage during the day. Regulators aim to stabilize the grid by encouraging energy exports during high-demand periods, offering rewards for exporting energy between 4 pm and 9 pm.
