Highlights for October 2023

Australian electricity and gas pricing

  • Spot markets were very soft in the month of October, averaging $29/MWh across the NEM. This was driven by mild temperatures leading to record low demand, and high renewable energy generation increasing supply (45.1% across the month).
  • There was a significant volume of negative price events in all states, most notably in QLD and VIC, as 31% and 29% of all price periods were negative, respectively.
  • The futures market declined in line with the spot markets in October, averaging $8/MWh lower for Cal24 Futures than September.
  • Gas prices firmed in October after hitting prices as low as $4.40 in VIC at the start of the month.

Carbon and environmental markets

  • ACCUs remained relatively steady across the month, with spot Generic ACCUs closing at $30.25.
  • LGCs saw a flattening of the forward curve, as there was a sell-off of spot and early vintages, and a firming of CY27 vintages and beyond.
  • STCs returned to a deficit in the clearing house, meaning the price remained at $39.90 for the entire month.

In other news

  • The Victorian government has announced they will re-enter the private market, as the state-owned utility (the SEC) is reinstated.
  • SA government has announced ATCO BOC Linde as the ‘preferred partners’ for the world’s largest hydrogen electrolyser and hydrogen gas generator (250MW and 200MW respectively).
  • ACCC has approved Brookfield’s takeover of Origin in a win for the renewable energy transition, despite concerns of the potential for Origin to ‘delay and frustrate’ the connection process of rivals.


Feature 1

Victorian Government launches state owned utility SEC

The Victorian Government has officially re-entered the private utility market, launching the State Electricity Commission (SEC).

The Victorian Government has re-launched the State Electricity Commission (SEC), looking to invest in renewable energy generation and storage technologies.

The SEC was the sole agency for the state's power generation, transmission and distribution for most of the 1900s.

Under the guidance of the SEC Expert Advisory Panel, the SEC will look to invest $1 billion in 4.5GW of new renewable generation and storage capacity. 2.6 of the 4.5GW will be invested by 2028.

The advisory panel outlined three priorities for the SEC:

  • Invest to accelerate the energy transition
  • Support the switch to all-electric households
  • Build a renewable energy workforce

The funds will mostly be aimed at investment in onshore generation and 2–4-hour storage.

The SEC is yet to announce their pioneer investment; however they have received over 100 Registrations of Interest (ROIs), combining 24GW of generation and 30GW of storage capacity.

SA Announces winners of 250MW hydrogen tender

The South Australian Government has announced ATCO and BOC Linde as preferred partners for the world's largest 250MW Hydrogen Electrolyser and 200MW Hydrogen Gas Generator.

The SA Government has announced winners of its green hydrogen tender, naming ATCO and BOC Linde as the ‘preferred partners.’

The projects, which will be built in Whyalla, will be the world's largest hydrogen electrolyser and hydrogen gas generator (at 250MW and 200MW respectively).

The Hydrogen Jobs plan, which allocated $593 million in state funding, also includes a 3,600-tonne hydrogen storage facility, equivalent to two months of production. SA infrastructure company EPIC Energy is the preferred developer of the storage facility and associated pipeline.

The project will be owned and operated by the state, aimed at reducing volatility and suppressing wholesale energy prices in SA. The combined electrolyser, gas generator and storage facility are anticipated to be online by Q1 2026.

The SA hydrogen production site allows for SA to decarbonize the hard-to-abate industries, such as production of green steel and green iron.

Feature 3

Introduction of Very Fast 1 second FCAS Market

AEMO officially launched the “Very Fast” 1 second Raise and Lower markets on the 9th of October.

On the 9th of October, AEMO opened the Very Fast FCAS service market.

Due to the decreasing inertia in the system as large synchronous generators leave the NEM, there is a need for the frequency to be adjusted on a smaller time scale.

The Very Fast FCAS market incentivizes participants on a 1 second basis to either:

  • Raise the frequency – by increasing the energy dispatched, or reducing demand
  • Lower the frequency – by reducing the energy dispatched, or increasing demand

There were 9 participants in the first 11 days of operation, most of which were grid scale batteries and C&I aggregators (that only participate in the Raise market, by switching off demand).

Prices in the Lower market were much higher (between $0-140/MWh) than the Raise Market (generally steady around $20/MWh).

The cap for each participant was quickly increased from 50MW to 100MW in the Lower market due to higher availability but remains at 50MW for the Raise market.

What this month’s developments mean for Australian business

The increase in renewable energy penetration coupled with the warmer weather and lower demand were the key drivers in the increase of negative energy price periods seen in October. While this is largely seasonal, we can expect scenarios like this to be, overall, more frequent as the renewable energy transition progresses.

Corporate energy buyers need to actively factor-in periods of negative pricing into their energy contract structure and negotiations. This starts with a setting an energy  that’s based on a sound understanding of current and forecast market dynamics.

In the Australian carbon market, the spot ACCU price remained relatively steady in the month of October. This may be, at least in part, due to delayed demand from Safeguard Mechanism participants who are yet to enter the market.

Our transactions and advisory teams, however, are seeing a heightened activity in deals made on the primary carbon market, through structures such as long-term carbon offtake agreements for example. Like power purchase agreements (PPAs), in a carbon offtake agreement the buyer agrees to purchase set volume of credits, at set price points, for multiple years into the future.

If your business has a defined carbon exposure a carbon offtake agreement is a contract mechanism that should be considered as part of your ongoing strategy.
