Another state launches Solar Sharer offer, amid fresh warnings of drawbacks to three hours of free power - Renew Economy

Another Australian state has launched a Solar Sharer scheme offering households three hours of free electricity daily during peak solar generation. The initiative draws fresh warnings from network operators and energy analysts about the drawbacks of the approach: it distorts price signals needed to manage demand, creates volatility in the grid that is harder to manage when supply is weather-dependent, and shifts costs to non-participating households and renters who cannot install rooftop solar.

Where this fits

This bears on the cost and reliability pillars of the renewable transition. Solar Sharer schemes mask the real cost of running a high-solar grid by suppressing peak-time prices when the sun shines hardest, which sounds consumer-friendly but removes the incentive for people to shift demand away from the narrowest generation window. On a grid with three to four hours of useful solar output daily, that window narrows further. The subsidy is real, even if hidden: it flows through network charges and cross-subsidies paid by other households. It also shores up an increasingly difficult balancing act: as solar capacity swells, managing the ramping demand at dusk and the duck curve becomes a grid operator's nightmare without firm, dispatchable power to fill the gaps.

What it means

Solar Sharer offers buy political acceptance for solar expansion by keeping the household bill artificially low during the day, but they entrench a grid design that depends on gas peaking plants, battery storage (which is expensive and China-sourced), and network overbuild to absorb the midday glut. Australia is locking in a high-cost, high-complexity, China-dependent system to firm a weather-dependent supply. The honest cost of that choice remains offstage.
