Post: Optimisation and market participation are not the same thing

Optimisation and market participation are not the same thing

Guest post by GridBeyond Business Development Director (AU), Mark Netto

Market participation gets your asset connected and settled. Optimisation determines how much it earns.

They are related but distinct — and solving for one does not mean you’ve solved for the other.

Two misconceptions are particularly common among new developers entering the sub-5MW market:

• that having a market access arrangement means the asset is being optimised
• that having an offtake structure removes the need to think about optimisation at all

Neither is true, and both are worth understanding before you sign anything.

The sub-5MW battery market is attracting a wave of developers who are entering the NEM for the first time.

Most of them move quickly to solve for market participation — finding a retailer or auto-bidding partner, understanding the FRMP registration process, establishing how the asset will be settled. That is the right instinct. You cannot earn revenue without it.

What often gets less attention is optimisation. Not because developers don’t care about it, but because the distinction between the two isn’t always obvious — particularly when the simplest market access arrangements appear to bundle both functions together.

They don’t. And the difference matters.

Two functions, not one

Market participation is the regulatory and commercial layer that connects your asset to the NEM. It covers AEMO registration, FRMP obligations, settlement flows, and the compliance requirements that come with being a market participant.

It answers the question: is the asset in the market and getting paid?

Optimisation is the intelligence layer that determines what the asset actually does in that market. It covers price forecasting, dispatch strategy, state of charge management, and — for hybrid assets — the co-ordination of solar generation and battery dispatch.

It answers the question: is the asset making the right decisions in every interval?

These are related. But they are not the same thing.

An asset can be fully market-compliant and consistently underperforming. It can be settled correctly and still be leaving significant revenue on the table every day.

Misconception one — market participation means optimisation

The most common version of this mistake happens when a new developer signs up with a retailer or an auto-bidding partner for market access and assumes the optimisation question is answered at the same time.

Retailers and auto-bidding platforms provide market participation. Most also provide some form of automated rebidding — a tool that submits bids based on predefined price points or simple rules.

That is not optimisation. It is automation.

Genuine optimisation involves AI-driven price forecasting, real-time state of charge management, dynamic marginal cost calculation, and continuous re-evaluation of dispatch strategy as market conditions change.

The difference in revenue outcomes between a rules-based auto-bidding tool and a purpose-built optimisation platform is material — and it compounds across every interval, every day, across the life of the asset.

Having a retailer or auto-bidding partner as your route to market does not mean your asset is being optimised.

It means it is in the market.

Those are different things.

Misconception two — an offtake structure means you don’t need to think about optimisation

This one is subtler and arguably more consequential.

Offtake structures take many forms in the sub-5MW market — PPAs, virtual tolls, revenue floors, cap contracts, hybrid merchant arrangements. What they share is a common purpose: providing some degree of revenue certainty, improving bankability, and reducing the developer’s exposure to spot market volatility.

For many projects, an offtake structure is an important — sometimes essential — part of getting to financial close.

What an offtake structure does not do is change how the asset interacts with the market.

Regardless of the contract structure sitting above it, the asset is still dispatching into the NEM on every interval. It is still settling with AEMO. It is still making decisions about when to charge, when to discharge, and how to position for the next period.

The offtake arrangement determines what the developer receives from the counterparty — not what the asset actually earns or costs in the market.

The gap between those two things is determined entirely by how well the asset is optimised.

Poor optimisation under an offtake structure doesn’t always show up immediately in the developer’s P&L — the contracted revenue provides a buffer. But it shows up in the offtaker’s economics, in the asset’s degradation profile, and eventually in the renegotiation conversation at the end of the contract term.

An asset that has been poorly optimised for five years is not in the same commercial position as one that has been well optimised — and both the offtaker and any future acquirer will know it.

An offtake structure is not a reason to deprioritise optimisation.

If anything, it is a reason to make sure the optimisation layer is robust enough to protect the economics of the contract from both sides.

One provider or two?

Understanding the distinction between market participation and optimisation also highlights the vendor question.

Some developers run them separately — a retailer or market access partner for FRMP, a separate software platform for optimisation. That works. But it creates two relationships to manage, two data sets to reconcile, and two parties to mediate between when performance doesn’t meet expectations.

In our experience, that last point is where the real cost sits. When an asset underperforms, the conversation between two separate providers rarely produces a clear answer quickly.

A single provider handling both functions changes that dynamic entirely.

One platform sees the full picture — market participation, optimisation, settlement, and performance — and one party is accountable for all of it.

For developers who want to go further, GridBeyond can act as the FRMP directly. That means the AEMO registration, market participant obligations, settlement flows, and all of the ongoing compliance requirements that come with NEM participation sit with us — not with the asset owner.

Combined with our optimisation platform and 24/7 NOC oversight, it means a new developer can focus entirely on owning and financing the asset. The market complexity is handled.

For a developer building their first sub-5MW project and navigating the NEM for the first time, that is not a minor convenience. It is a material reduction in operational risk.

The question worth asking early

Before selecting a market access arrangement, it is worth asking explicitly:

Does this solve for market participation, optimisation, or both — and how do I know the difference?

The answer will tell you a lot about what you are actually buying.
