On July 1, the Australian government flipped a switch on something called the Solar Sharer programme. From that day, energy retailers in New South Wales, south-east Queensland, and South Australia must offer households with smart meters at least three hours of free electricity in the middle of the day. The climate change and energy minister, Chris Bowen, framed it as a way for households without rooftop panels to benefit from the country’s solar glut. The predictable reactions arrived on schedule: government forcing private companies to give away product, a gimmick that will just get cross-subsidised into higher evening rates, another brick in the edifice of Australian energy dysfunction.

All of that misses what is actually interesting here.

The free electricity was already free. Retailers just weren’t telling anyone.

The Spread They’d Rather You Didn’t Notice

By Q4 2024, negative prices accounted for 23.1% of trading intervals in Australia’s National Electricity Market — a record, and one that has almost certainly been broken since. When wholesale prices go negative, generators are literally paying the grid to take their power. Solar floods the system at midday, demand doesn’t rise to meet it, and the spot price dives below zero. This is not a secret. It is the defining feature of a grid that has built solar capacity faster than it has figured out what to do with it.

What happened to those negative prices at the retail level? Nothing. Households kept paying positive rates through the sunniest hours of the day. The retailers bought low — sometimes below zero — and sold at the standard tariff. The spread was pure margin, and it was enormous.

One energy trader, messaging from a desk in Melbourne during Tuesday’s midday trough, put it bluntly: “We’ve been buying at minus twenty bucks a megawatt-hour and selling it back to residential customers at two hundred. The Solar Sharer doesn’t create a subsidy. It just makes us stop charging for something that costs us nothing.”

That is the quiet truth of the programme. It is not a handout. It is a pass-through mandate. The government looked at a market where the wholesale price had collapsed and noticed that retail prices hadn’t budged. So it wrote a rule requiring retailers to reflect the reality they were already trading on.

The Real Subsidy Ran the Other Way

This is where the conventional right-of-centre critique gets the story backwards. The complaint is that Solar Sharer forces a cross-subsidy — daytime freeloaders will be paid for by households who use power at night. But the cross-subsidy was already running, and it ran from consumers to retailers. Every household paying 30 cents per kilowatt-hour at 1 p.m. while their retailer paid negative wholesale rates was already subsidising something: the retailer’s margin.

The Australian Energy Regulator confirmed retail price increases of up to 9.7% for households in 2025-26. Those increases landed on top of a wholesale market that was, for significant stretches of the day, paying people to take power. If you are looking for a transfer of wealth, start there.

Solar Sharer doesn’t eliminate the evening peak problem. It doesn’t solve the duck curve, or the need for storage, or the fact that someone has to pay for the poles and wires. But those problems existed before July 1, and they will exist after. What changed is that a chunk of the surplus created by Australia’s solar buildout is now visible on household bills instead of buried in retailer spreadsheets.

What the Programme Actually Tests

The interesting question is not whether three free hours is good policy. It is whether retailers can survive having their margins exposed. If the business model depends on charging customers for electricity that costs nothing to procure, the business model was already on borrowed time. Solar Sharer just names the date.

Some retailers will handle this fine. They will bundle the free hours with storage offers, or time-of-use plans that price the evening peak honestly, or services that shift load into the midday window. Others will complain loudly and hope voters blame the government. The ones that complain loudest are worth watching: they are telling you, in effect, that their margins were built on an arbitrage they never intended to share.

Queensland alone has 1.16 million rooftop solar installations and 7.2 GW of total capacity. That is not a policy choice; it is a physical fact. The electrons are arriving whether retailers have a pricing strategy or not. Solar Sharer is less a revolution than an acknowledgement — a regulatory shrug that says, fine, if the power is free at noon, the bill should say so.

The Uncomfortable Lesson

There is something here that should make free-marketers pause. The government did not create the free electricity. The market did — through a decade of rooftop solar adoption, falling panel costs, and feed-in tariffs that were themselves a policy intervention. What the government did was notice that a market outcome was being intercepted before it reached consumers, and it wrote a rule to complete the circuit.

You can call that overreach. Or you can call it the thing that happens when an industry declines to pass through a benefit voluntarily and then acts surprised when someone makes it mandatory. Either way, the three free hours are not the interesting part. The interesting part is that they were always there, and nobody was supposed to know.
