Batteries Are Now Setting Prices. Domestic Gas Just Hit a Four-Year Low. And Your Contract Might Be Built on Outdated Assumptions.
AEMO’s Q1 2026 Quarterly Energy Dynamics report landed this month. Here’s what the data actually says — and what it means if you’re a large or complex energy user in Australia.
Every quarter, AEMO publishes its Quarterly Energy Dynamics (QED) report — the most comprehensive energy market update Australia has. It’s data-rich, runs to nearly 100 pages, and most businesses don’t have the time or context to translate it into decisions.
That’s what we’re here for. This is our read of the Q1 2026 QED — Australia’s most detailed energy market update — not a summary, but an interpretation. What shifted, why it matters, and what you should be thinking about right now if you’re a large energy user.
Electricity prices fell. But not everywhere, and not without volatility.
The headline number is a 12% year-on-year drop in NEM-wide wholesale spot prices, which averaged $73/MWh across Q1 2026. On face value, that sounds like good news. For most regions, it was. Victoria recorded the steepest fall, averaging just $43/MWh, down 28% from the same quarter last year. Queensland and New South Wales also saw meaningful reductions.
But South Australia told a different story. It was the only NEM region to record a year-on-year price increase, averaging $88/MWh — up 33%. A single weather-driven volatility event on 26 January contributed $26/MWh to that quarterly average on its own. When interconnectors were constrained and cooling demand surged above 43°C in Adelaide, prices hit $19,000/MWh across 28 dispatch intervals in a single evening.
If your sites are in South Australia, or you have exposure through a partially pass-through contract, Q1 2026 was a painful reminder that headline averages don’t tell the whole story. The risk is in the volatility, not just the mean.
Batteries are now the dominant price-setter. That changes the game.
This is the most structurally significant finding in the Q1 2026 report, and it’s one that will have lasting implications for how large energy users manage their exposure.
For the first time, batteries displaced hydro as the most frequent price-setting technology across the NEM, accounting for 32% of all price-setting intervals. In Queensland and New South Wales, batteries set prices in more than 40% of intervals. That’s a fundamental shift in market dynamics.
The practical effect is twofold. Battery charging during the day is pushing up midday prices, while battery discharge in the evening is suppressing peak prices. The daily price profile is flattening. The old assumption that peak-period exposure is your biggest risk is becoming less reliable as a guide.
This matters for embedded networks in particular. If you’re operating an embedded network or procuring on behalf of a mixed tenant base, the intraday price signal is changing shape. Strategies built on historical peak-to-off-peak spreads may need revisiting.
The battery revolution isn’t coming — it’s here. Over 4,400 MW of new large-scale battery capacity entered the NEM in the past year, more than doubling total installed capacity. The market is being repriced in real time.
Gas prices hit a four-year low domestically. International markets told the opposite story.
East coast wholesale gas prices averaged $10.61/GJ in Q1 2026 — down 20% from Q1 2025, which was itself a record high. By March, the average had dropped further to $9.22/GJ, the lowest monthly average since January 2022.
The drivers were domestic: record-low gas-fired generation demand (batteries and wind displaced gas at the evening peak), increased supply flowing south from Moomba, and a significant shift in market participant bidding behaviour in March.
Meanwhile, international LNG spot prices were doing the opposite. A military escalation in the Middle East in early March disrupted Strait of Hormuz transit, halted significant LNG supply from Qatar, and sent Asian LNG prices more than doubling from their February levels. The ACCC netback price surged, with six-month forward prices ranging from $23.69/GJ to $25.20/GJ.
Domestic and international gas markets have rarely diverged this sharply. That divergence won’t last forever. For businesses using this energy market update to inform their Australia procurement decisions, the current domestic pricing environment is a window, not a new baseline. For businesses with gas contracts up for renewal in the next 12 months, this is a conversation worth having now rather than later.
Renewables hit new records. So did the infrastructure pressure that comes with them.
The renewable share of NEM generation reached a new Q1 high of 46.5%, up from 42.5% in Q1 2025. Grid-scale solar hit an all-time quarterly record. Wind output reached a new Q1 high, driven largely by new capacity coming online in Queensland. The energy transition numbers are real and accelerating.
But the report also flags growing network pressure. Solar curtailment due to network constraints nearly doubled year-on-year, averaging 246 MW across Q1 2026. Total network curtailment of wind and solar reached 296 MW — almost double Q1 2025. The grid is struggling to absorb what’s being connected to it.
For businesses investing in on-site generation or evaluating solar-plus-battery projects, this is worth understanding. Network constraints aren’t just a wholesale market issue — they affect behind-the-meter economics and the value of export agreements too.
Underlying demand is growing again. Quietly.
One number that tends to get lost in the renewables conversation: NEM-wide underlying demand averaged 25,496 MW in Q1 2026, a new quarterly record, up 1.2% from Q1 2025. The growth is being driven by electrification, population increase, and data centre demand, particularly in New South Wales where data centre load averaged 398 MW — up 18% year-on-year.
Distributed solar output is currently masking this growth at the operational demand level. But as electrification of industrial processes and fleet vehicles accelerates, load growth will become harder to offset. Supply adequacy is not a solved problem. Staying across these shifts in real time is exactly what the Empower Portal is built for — giving large energy users visibility over their energy data when the market is moving.
What this energy market update means for Australian C&I users right now
The Q1 2026 energy market update for Australia points to a few clear priorities for commercial and industrial businesses thinking about their energy strategy.
Review your contract structure against the new price shape
The flattening of the daily price profile changes the value of time-of-use strategies and peak demand management. If your contract was structured around an older price shape, it may not be working as hard for you as it should. Our energy procurement team works with large and complex energy users to structure contracts that reflect current market conditions, not last year’s assumptions.
Don’t confuse low domestic gas prices with long-term stability
The gap between domestic and international gas pricing is historically wide right now. Middle East supply disruption and European demand for LNG alternatives could close that gap quickly. If gas is material to your cost base, act on the current domestic pricing while it lasts.
Understand your exposure to volatility, not just average prices
South Australia in January is a case study in why average pricing figures can be misleading. Know your contract structure, understand where your pass-through exposure sits, and make sure your procurement strategy accounts for tail risk.
Think carefully before making energy investment decisions without current market context
The battery market, the curtailment environment, the shifting intraday price shape — these are all moving fast. Investment decisions in on-site generation, storage, or demand management that don’t account for Q1 2026 market conditions may be working from outdated assumptions.
Frequently asked questions
What is the AEMO Quarterly Energy Dynamics report?
The Quarterly Energy Dynamics (QED) report is published by the Australian Energy Market Operator (AEMO) each quarter. It provides a comprehensive overview of electricity and gas market outcomes across the National Electricity Market (NEM) and Western Australia’s Wholesale Electricity Market (WEM), including wholesale prices, generation mix, demand trends, storage activity, and gas market dynamics. It is one of the most authoritative sources of energy market data in Australia.
What is price-setting in the electricity market and why does it matter?
In the NEM, the wholesale electricity price in each dispatch interval is set by the most expensive generator needed to meet demand at that moment — known as the price-setter. The technology that sets the price determines the price level. When lower-cost technologies set prices more frequently, average wholesale prices tend to fall. When higher-cost or more volatile technologies are marginal, prices can spike significantly. Understanding what is setting prices — and when — is fundamental to assessing wholesale electricity cost risk.
What is an embedded network and how is it affected by wholesale energy market changes?
An embedded network is a private electricity network operating within a larger property or precinct — common in commercial buildings, shopping centres, industrial estates, caravan parks, and residential apartment complexes. The embedded network operator purchases electricity at wholesale or negotiated rates and on-supplies it to tenants or occupants. Changes in wholesale market structure, including shifts in intraday price shape and regional price volatility, directly affect the cost of energy procured for embedded networks and the viability of on-supply tariff structures.
What is the ACCC LNG netback price and how does it relate to domestic gas prices in Australia?
The ACCC LNG netback price represents the price at which it would be economical for gas producers to sell gas domestically rather than export it as LNG. It is calculated by taking the international LNG spot price and subtracting the costs of liquefaction and shipping. It acts as a ceiling indicator for domestic gas prices — when international LNG prices rise sharply, as occurred in Q1 2026 due to Middle East supply disruption, the netback price increases, which can put upward pressure on domestic contract gas prices over time.
What does energy procurement mean for large and complex energy users?
Energy procurement for large and complex energy users — including multi-site businesses, industrial operations, and embedded network operators — involves far more than simply choosing a retailer. It includes understanding wholesale market exposure, structuring contracts to manage price and volume risk, timing procurement decisions against market conditions, and ensuring that tariff and contract structures reflect the actual load profile and operational requirements of the business. Effective procurement can represent a significant cost advantage for high-consumption businesses.
Your energy strategy should reflect today’s market, not last year’s.
