Why Australia needs locational pricing

Issue 15: Australia's electricity market needs better price signals that reflect local conditions

Australia’s electricity prices ignore location, even though the grid doesn’t. This mismatch drives congestion, curtailment, and inefficient investment. There is a better system used in much of the world. Locational marginal pricing aligns prices with physics, improving coordination of batteries, generation, and demand. It adds complexity, but the cost of today’s overly simple price signals is rising as the system becomes more distributed and constrained.

Here comes the AI...

Issue 14: Why Australia needs data centres — and why they must become a core part of the electricity system

After twenty years of flat demand, AI data centres are bringing massive load growth back to Australia's electricity grid. The question is not whether we can handle it, but whether we're smart enough to shape it.

Australia is winning the battery race. Now what?

Issue 13: Australia's grid batteries are starting to matter, but the real future could be right under our noses.

Why the headline numbers flatter us, what “enough storage” actually means, and why the next move is sitting in two million garages.

Grid stability has some important new tools

Issue 12: Distributed energy resources increasingly keep the system stable. Time they were better recognised.

In California, the physical system that keeps the grid running has already changed. The market is still catching up. A new proposal to give distributed energy resources clearer pathways into the system is an important part of that.

Free power at lunch and the democratisation of energy storage

Issue 11: Australia is awash with energy at noon—who gets to store it?

Victoria’s recently announced "free daytime power" plan may look like a consumer giveaway but in fact it is recognition of a market signal. It tells us that midday electricity is now so plentiful that it makes no sense to charge for it. Once that becomes explicit, the real question is not whether power should be free for three hours. It is who gets to store it.

Rebuilding the rhythm — learning to keep time again

Issue 10: Part 2 of "When the rhythm section fades..." on the replacement of large spinning generators with power electronics

In the last post on this topic , I observed that the grid is losing its rhythm section. For decades, large synchronous generators — coal, gas, hydro — acted like the drummer and bassist of the system. They didn’t just produce energy. They held everything together. Frequency, voltage, stability — all of it emerged from the physical behaviour of spinning machines. That rhythm is fading. This piece is about what replaces it.

The grid squeeze: Our grid Is not full, but we keep building it.

Issue 09: How demand flexibility and distributed batteries could defer $100 billion in grid infrastructure

A coalition of US tech giants claims using our existing electricity networks better could save $100 billion in grid infrastructure costs. They are probably right. In Australia we are still building more networks to carry less electricity.

Connection Pending

Issue 08: Why Australia's EV charging rollout is stalled by 18–36 month grid connection delays

Grid connection delays of 18–36 months and costs of hundreds of thousands of dollars per site are throttling fast charger deployment in Australia, particularly in the bush. EV sales are rising quickly. Infrastructure is not. The constraint is not capital. It is connection. We need a dedicated funding programme for long-distance charging infrastructure.

Nikola's Ghost and Elon's Taxis

Issue 07: Tesla's wireless Cybercab charging, Nikola's legacy, and the grid-entangled economics of autonomous EV fleets

Tesla's FCC approval for wireless Cybercab charging appears to echo Nikola Tesla's century-old vision. In reality autonomous taxis, wireless charging, ERCOT’s volatile nodal market and a lot of storage are about to collide. The 21st century Tesla may be the winner.

Issue 06: Australia's energy security in a world at war — oil dependence, gas exports and the renewable hedge

While Australia awakens from another blissful summer the world is at war. Our energy supplies are being severely disrupted. Battling Entropy identifies the single most effective thing we can do about it: electrify more of our transport.

When the rhythm section fades...

Issue 05: What happens to grid stability when synchronous generators retire and inverters take over

For a century and a half, the steady beat of our electricity system came from spinning steel. The inertia of synchronous generators held the 50Hz rhythm steady as a mechanical side-effect of rotation. That era is ending. In a grid dominated by power electronics, stability is no longer a by-product of physics. It must be specified, tested, validated and governed. A recent white paper from Australian researchers makes the challenge explicit: we are virtualising the grid without yet having a national architecture to verify its behaviour under stress. The transition that matters for the grid is not from coal to solar and wind. It is from inertia to firmware. That demands a new discipline of coordination, markets and institutional design.

Massachusetts uses energy markets to reduce copper build-out

Issue 04: National Grid's DER marketplace in Massachusetts tests whether markets can solve grid constraints

National Grid's new DER marketplace in Massachusetts is testing a fundamental question: can distributed energy resources solve grid bottlenecks more cheaply than traditional infrastructure—and can markets coordinate them efficiently enough to matter?

China's solid-state battery standard is all about V2G, not range

Issue 03: China's solid-state battery standard, BYD's 2027 production target, and the vehicle-to-grid endgame

China is standardising solid-state EV batteries with BYD starting production as soon as 2027. This is about unlocking the economics of full scale grid integration of EV batteries.

The Battling Entropy Manifesto

Issue 01: Civilisation is a local rebellion against the universe

Entropy is relentless. Civilisation is resistance. Technology, collapsing costs, and bold imagination let us redesign energy and create islands of coherence in a chaotic world.

Nuclear power could destabilise the market

The federal opposition’s push for government-owned nuclear power in Australia threatens to destabilise our electricity market, undermining the sophisticated market-pricing system that has evolved since the 1990s.

Jan 16, 2025

The Federal Opposition's nuclear policy is dangerously misguided

For decades, conservative governments championed the privatisation of the energy sector, creating a real-time market that balances supply and demand across coal, gas, wind, solar, and hydro. Now the same party wants to reimpose centralised control under a re-nationalised nuclear generating sector. That would be a colossal mistake.

FROM THE ORIGINAL 2016/17 SITE: Privacy is stone dead. Let's make sure we all understand that. It died a slow and largely unlamented death over the period 1998 to 2015. Contrary to popular opinion, it's murderer wasn't government.
