What’s already changing in Australia’s energy market as the NEM Review lands

As the NEM Review lands, attention rightly turns to system-level settings. But much of the commercial change shaping renewable and firming supply is already unfolding inside over-the-counter (OTC) energy markets. This article sets out what’s already shifting commercially in a market under review.

What’s already changing in Australia’s energy market as the NEM Review lands

Energy contract innovation is often invisible to market participants

Over-the-counter (OTC) energy markets are moving quickly as corporate renewable procurement starts to re-engage in pockets and project economics continue to shift.

These are the deals shaping how risk is allocated and how new renewable energy projects reach financial close - but they remain largely invisible unless you’re working directly on them.

The NEM Review’s final report, released today, reinforces this point by calling out the limited visibility across OTC (off-exchange) contracting.

In this article, we use ‘OTC’ in the same broad sense as the Review, to capture the full spectrum of off-exchange bilateral contracting, from long-term offtakes through to shorter-dated hedging activity.

The release of the final report provides a useful moment to look at what’s changing inside wholesale and retail offtake markets, and how these changes sit alongside the broader policy discussion.

This article is written for project developers, corporate energy buyers, intermediaries and investors who want a clearer view of how current contracting trends are interacting with broader market dynamics.

It builds on the themes we’ve explored throughout the year, with updated insights from our recent buyer and developer engagements. In this piece, we outline:

  • Forces influencing contract design in both wholesale and retail offtake markets
  • Where corporate demand and project economics are shifting
  • Early signals we’re watching across transactions
  • How these commercial trends relate to the broader visibility challenge surfaced by the Review

We’ll incorporate the Review’s outcomes across our commentary in the coming weeks, particularly where they intersect with contracting, liquidity and project development.

OTC energy deals are revealing the real commercial developments

Bilateral offtake discussions are one part of the broader OTC market, and they’re often where the earliest adjustments to market conditions occur. For example, as The Energy noted, so-called “super-peak” swap contracts were traded on the OTC market several years prior to them being traded on the ASX.

Across this broader OTC activity, buyers and sellers are testing different approaches to firmness, flexibility and risk allocation in an ever-changing environment. These dynamics aren’t visible in exchange data or system-level settings, but they have a material influence on how projects progress towards financial close.

In the context of the NEM Review’s final report, it’s worth recognising that many of the commercial signals shaping contracting behaviour and liquidity formation are already emerging across the OTC market, including long-term offtakes and the downstream retail agreements.

These commercial signals set the context for the contract innovation we explore next.

What’s driving energy contract innovation

Buyers and developers are responding to the same underlying conditions. As expanded on below, these conditions include:

  • a shift in technology costs, with wind build costs elevated, while costs for solar and especially batteries falling
  • a backwardated wholesale price curve, with near-term prices higher than longer-term prices
  • changes in policy signals at the utility-scale (such as the NEM Review) and at the small-scale (in particular, the meteoric rise in behind-the-meter battery uptake since July), and
  • different dynamics at play in single-asset versus, portfolio contracting.

The shared market pressures are shaping how parties think about firmness, flexibility and exposure, and they’re influencing the ever-evolving nature and structure of OTC contracting.

While these factors impact each side differently, they form the backdrop for the adjustments we’re seeing across current OTC activity.

Buyer-side drivers

A few buyer-side pressures are standing out clearly in bilateral activity.

  • Corporate renewable procurement is re-engaging after a period where many organisations slowed or deferred decisions due to price volatility and internal uncertainty. With the moderation in labour and other input costs post-COVID, buyers increasingly have the financial headroom to again evaluate Scope 2 decarbonisation. In addition, short-term hedging has carried some organisations through the price volatility of the past few years, but many are now approaching the point where longer-term procurement needs to be locked in to support 2030 targets and beyond.
  • Decision cycles are lengthening as organisations work through more structured procurement processes and internal governance. CFO and finance teams are looking closely at exposure to shape, volume and budget risk under different contract configurations, which is slowing decision cycles and influencing appetite for contract tenor, flexibility and risk.
  • Expectations around firmness and load alignment are becoming more specific. Buyers are moving beyond generic renewable offtakes toward structures that better reflect their underlying load shape and exposure. This is prompting more detailed conversations about shaping, flexibility and the role of firming within contract structures, including early interest in hybrid supply models.
  • Re-emergence of interest in additionality of renewables procurement, albeit currently still limited to large C&I customers like data centres and energy-intensive loads.
  • Early signals of more granular demand-supply matching with discussion of moving to intra-quarterly matching, as potential stepping stone to hourly matching (or “24/7 PPAs”).

These buyer-side shifts are shaping how OTC structures are evolving and creating the conditions developers are now responding to.

Developer-side drivers

Developer-side dynamics reflect a different set of pressures.

  • Project costs have risen materially. Higher capex, construction costs and equipment prices are shaping the contract terms developers need in order to progress projects.
  • Financing approaches have changed. Larger developers can access portfolio-level financing that may come with less stringent contracting requirements than single-asset non-recourse structures.
  • Delivery and sequencing risk is more pronounced. Longer lead times, an elongated approvals process, shifting engineering, procurement and construction (EPC) terms and grid-related timing risks are influencing how developers manage exposure and negotiate commercial allocation.
  • Bankability requirements continue to influence contract design. Financiers place more weight on structures that are asset linked and reduce exposure to extreme time-of-day pricing or other adverse events, prompting developers to explore offtake terms that balance buyer needs while achieving higher pricing without shifting all risk onto the project.
  • Projects are adapting to generation–load mismatches, particularly as buyers become more specific about their demand profiles. This is leading to more detailed conversations about shaping, delivery schedules and firmness pathways.
  • Hybrid supply and storage-linked options are becoming part of commercial discussions as developers consider pathways to firmed supply or more flexible offtake structures, though cost and financing conditions continue to determine feasibility.

Together, these developer-side pressures are driving the evolution of offtake structures and shaping the OTC contracting environment for 2026 and beyond.

What this activity means for a market under review

As the final NEM Review lands, much of the attention will fall on system design, investment signals and the long-term settings needed to deliver new supply.

But the adjustments moving through bilateral activity within the OTC market provide an early view of how buyers and developers are already responding to these same conditions in practice.

These commercial signals sit underneath the Review’s system-level analysis and help show how risk is actually being allocated as the market prepares for the next phase of investment.

While the Review will clarify the structural parameters shaping the market, it will not capture the detailed commercial adjustments already occurring across OTC contracting.

Bilateral contracting – as a core part of OTC activity - reveals which products are gaining traction, where liquidity is forming or stalling, and how projects are progressing toward financial close.

These insights are important because they highlight the practical conditions under which the system the Review is examining will operate.

A few implications stand out.

  • Liquidity is forming unevenly. Deal flow is highlighting where contracting interest is concentrating and where products are fragmenting, offering early indications of which structures are supporting active negotiation.
  • Bankability is being shaped by contract structure. How profile risk, firmness pathways and exposure to time-of-day pricing are managed has a direct influence on potential financing terms.
  • Sequencing pressures remain material. Projects are balancing delivery timelines, EPC uncertainty and the timing of revenue commitments. Bilateral negotiations are revealing where sequencing gaps may slow progress toward FID.
  • Buyers are recalibrating their risk strategies. Approaches to cost exposure, shape mismatch and the role of short-term hedges vs longer-term offtake are shifting, affecting timing and contract design.
  • The visibility gap persists. Many of the adjustments buyers and developers are making are not captured in exchange data or formal reporting. These signals are important for policy alignment but sit largely outside the public view.
  • Current activity is moving ahead of broader market indicators. Bilateral contracting across OTC markets provides a view into how commercial decisions are being made as the market adjusts to both current conditions and the system settings under review.

These developments help set the scene for the deeper discussion we’re planning for early Q1.

How these trends shape the next phase of Australia’s energy transition

The contracting shifts outlined in this article sit within a much larger energy transition.

As renewable supply, storage and firming requirements rise through the decade, the way risk is allocated across OTC contracting will be a key determinant for the pace at which new capacity progresses.

These dynamics won’t change overnight with the release of the NEM Review, but they will shape how its system-level settings translate into commercial decisions on the ground.

Understanding these signals matters for developers working toward financial close, for buyers managing exposure as load profiles evolve and for intermediaries and financiers navigating liquidity and bankability in a tightening market.  

CORE Markets will continue to reveal these adjustments before they appear in broader indicators, making OTC contracting an important area to watch through 2026 and beyond.

In the new year, we’ll host a discussion with buyers, developers and intermediaries to examine these contracting shifts in more detail, drawing on front-line experiences and the insights we see across transactions.
