Solar Power Turned off
Too much solar power is causing a problem.
Energy authorities in South Australia have used their new power to remotely switch off thousands of household solar panels for the first time, making the intervention when electricity demand plunged over the weekend.
Last year, transmission authorities were given permission to deliberately "trip" existing rooftop solar panels in rare circumstances to prevent sudden dips in demand leading to widespread blackouts.
The Australian Energy Market Operator (AEMO) recommended the measure as a means of mitigating the threat to grid security posed by the rapid growth of rooftop solar, which has led to days of very low demand.
