South Australia became the worlds largest jurisdiction to have their energy demands met completely by solar power.
100% of energy demands were met for just over an hour on October 11th. Consumer rooftop solar contributed 77% of this, with the remaining coming from large-scale solar farms in Tailem Bend and Port Augusta.
Already 288,000 homes have rooftop solar installed in South Australia, about a third of all South Australian homes. This number is expected to grow by 12.5% in the next 14 months to around 324,000 homes.
With rooftop solar becoming more commonplace, energy demands in South Australia will be met more frequently by renewables. Excess power generated by gas and wind farms is stored in batteries or exported to Victoria via the interconnector.
However, there are concerns that an excess of energy generated could cause instability in the grid. New powers passed last month allowing electricity distributors to switch off new solar panels as a last resort if the system was under too much pressure. New inverters installed must include software that allows them to be controlled remotely.
Earlier this year, plans were announced to build a $1.5 billion interconnector between S.A. and N.S.W. This would allow excess power generated to be exported interstate and lower power prices.
Currently as a Victorian, you can get paid for feeding excess solar power back into the grid as a ‘feed-in tariff’. The tariff is different depending on a number of factors, but is just one of the incentives in place to encourage solar installations.
