Edition #5 — June 2026
Welcome back to Behind the Meter. The fortnight gone has handed us one of the more revealing regulatory documents I've read in a while: the AER's final Default Market Offer for 2026-27, with a brand-new product attached called the Solar Sharer Offer. Three hours of free electricity in the middle of the day, mandated across NSW, South East Queensland and South Australia from 1 July.
It is being reported as a consumer-friendly gimmick. It is not. It is the first regulated retail product in this country designed around a wholesale market that has run out of conventional ways to clear daytime energy.
The Take: Free midday power isn't generosity, it's a regulator admitting the merit order has broken
The final 2026-27 DMO cuts standing-offer prices by 3.4% to 10.7% for households across most regions, and as much as 20.9% for small businesses in NSW. That is the headline. The more interesting piece, buried under the price-fall narrative, is the mandatory Solar Sharer Offer every retailer has to make available from 1 July. Households with smart meters in the DMO regions can opt in and take up to 24 kWh per day of free electricity during a three-hour midday window. NSW and South East Queensland set the window at 11am to 2pm, South Australia at 12pm to 3pm.
Read the design closely and the story becomes clearer. The free-period kWh is not actually free, it is recovered through higher peak and shoulder rates so the annualised price matches the time-of-use DMO in each zone. The AER is not handing out free power. It is forcing the retail layer to expose a wholesale reality the contract market has been politely working around for two years: midday energy is structurally surplus, and someone has to write it into a tariff.
What this signals about the price-setting environment is the part worth sitting with. In Q1 the NEM cleared at $73/MWh on average, 12% down year-on-year (AEMO Q1 QED), and batteries set the marginal price 32% of the time. The middle of the day routinely clears at or below zero in the regions where the Solar Sharer applies. Retailers are being handed a regulatory tool to push consumption into a window where their wholesale cost is genuinely negative on a meaningful number of days. The arithmetic works for the retailer. It also creates the first regulated demand-shifting signal we have ever had in a residential tariff.
The bit that matters for the commercial side is what this dress rehearsal foreshadows. The same logic, scaled to a C&I demand profile, lands inside the next round of network tariff resets. If midday energy is worth less than zero often enough to warrant a free-power retail product, the value of solar exported in that window collapses, the value of load-shifting and storage in that window climbs, and the spread the retailer can capture on a flat-priced commercial contract widens. Every flat-rate C&I offer signed in the past 18 months is being subsidised, quietly, by the customer who can't move load. The Solar Sharer makes that arithmetic visible at the household level. It will not stay there.
What I'd be doing right now if I were advising on a commercial portfolio in NSW, SEQ or SA. First, check whether any of your sites have material daytime load that you've been treating as inflexible. The economics have moved. Second, if you have rooftop solar exporting into the middle of the day for a few cents per kWh, the value case has shifted from export revenue to self-consumption and storage, and the next contract should reflect that. Third, the same regulatory instinct that produced the Solar Sharer for households will, within one or two reset cycles, show up as a much harder time-of-use signal on commercial network tariffs. The portfolios that win the next five years are the ones whose load can move. The portfolios that lose are the ones still paying flat rates designed for a 2022 wholesale curve.
Quick Hits
-
CIS Tender 7 cleared 7.8GW of renewables, with batteries taking half the room. The Tender 7 results awarded contracts across 19 projects, eight of them hybrid wind-or-solar plus battery, delivering more than 2GW and 7.9GWh of storage on top of the generation. Tender 8, focused on dispatchable capacity and another 16GWh of storage, lands later this month. The pattern is hard to miss. The federal government is using the contracting scheme to bias the new build toward firming, not pure generation. Anyone modelling a long-tenor PPA on a merchant solar tail should be assuming the daytime energy stack gets even more crowded between now and 2028.

Ofgem lifted the UK price cap 13% from July, and the reason matters. The Q3 cap jumped to £1,862 for a typical household, with gas up 24% and electricity up just 5%. The split is the interesting part. The UK still prices most of its power against gas at the margin, so a gas-driven shock flows straight through to retail. We are watching, in real time, the difference between a market where storage and renewables increasingly set the price (Australia, Q1 down 12%) and one where gas still does (UK, Q3 up 13%). For anyone advising clients with operations in both jurisdictions, the divergence is going to widen, not close.

Australia's first 8-hour grid battery hit full operations in NSW. RWE's 50MW / 400MWh Limondale BESS entered full operations on 28 May, sitting on the first Long Duration Storage LTESA written by AEMO Services. Two-hour batteries do daily arbitrage. Eight-hour batteries start to push into the territory that has been the exclusive preserve of hydro and gas peakers for evening firming. Limondale on its own is small. As a template for the next 16GWh of CIS Tender 8 storage, it is the shape the market is moving toward.
From the blog: If the Solar Sharer logic prompts a question about how time-of-use, network charges and demand pricing actually flow through to a commercial bill, the piece I wrote on tariff optimisation for Australian commercial sites walks through the mechanics. The cost recovery puzzle is moving from household tariffs into commercial ones next.
Three hours of free power in the middle of the day looks like a consumer feature. It is also a signal that the regulator has, for the first time, written a retail product around the fact that the wholesale market can no longer clear daytime energy at a positive price often enough to ignore. The reset cycle that follows will reach the commercial side. Better to be ahead of it than catching up.
Until next fortnight,
