The recent flare-up in Middle Eastern tensions has sent the usual suspects into a predictable tailspin. Analysts are dusting off decades-old blueprints for the ASEAN Power Grid (APG), claiming that the threat of an oil shock is the final "catalyst" needed to integrate the region’s electricity markets.
They are wrong.
The idea that a unified grid across ten sovereign nations with radically different economic priorities will solve energy insecurity is not just optimistic; it is dangerous. We are being sold a fairy tale of "interconnection" that ignores the brutal physics of transmission and the even more brutal reality of nationalist politics. I have spent years watching energy ministries nod politely at regional summits, only to go home and double down on domestic coal or gas because they know the truth: relying on your neighbor for the lights to stay on is a strategic suicide pact.
The Myth of Regional Solidarity
The prevailing narrative suggests that because Singapore is hungry for green energy and Laos has excess hydropower, a subsea cable is the obvious solution. This "lazy consensus" assumes that the primary barrier to the APG is technical or financial.
It isn't. It is an issue of trust.
Energy is the lifeblood of sovereignty. In a crisis—the kind of crisis an Iran-Israel conflict would actually trigger—governments do not honor export contracts. They protect their own. If Indonesia or Malaysia faces a domestic supply crunch due to soaring fuel costs, do you honestly believe they will prioritize sending electrons to Singapore’s data centers over keeping their own cities from rioting?
We saw this during the pandemic with medical supplies and food exports. Energy is even more sensitive. A regional grid creates a "tragedy of the commons" where the most vulnerable state dictates the stability of the entire network. Without a supranational regulator with the power to penalize sovereign states—something ASEAN’s "non-interference" policy strictly forbids—the APG is a wire to nowhere.
Subsea Cables are Not the Answer
The technical fetishization of high-voltage direct current (HVDC) subsea cables ignores the sheer scale of the engineering nightmare. Proponents point to the Australia-Asia PowerLink as a North Star. Yet, that project has faced repeated restructuring and existential financial questions.
Laying thousands of kilometers of cable through some of the most contested maritime territory on earth is a security nightmare. In a world of hybrid warfare, a subsea power cable is a giant, stationary target. We have seen how easily pipelines like Nord Stream can be "neutralized." Transitioning from a reliance on oil tankers—which can at least change their route—to a fixed, vulnerable cable is a step backward in strategic flexibility.
Furthermore, the "grid" enthusiasts fail to account for the massive transmission losses over these distances. Physics is indifferent to your "green transition" goals. Moving power from the mountains of Laos to the tip of the Malay Peninsula involves a tax paid in heat and resistance that makes the levelized cost of energy (LCOE) look far less attractive than decentralized, local production.
The Decentralization Counter-Intuition
The real solution to an energy shock isn't a bigger grid. It is a smaller one.
If you want to insulate an economy from a Strait of Hormuz blockade, you don't build a $20 billion extension cord to a neighbor who might cut it. You build radical domestic autonomy.
- Industrial-Scale Storage, Not Interconnection: Instead of spending billions on subsea cables, ASEAN nations should be pouring that capital into long-duration energy storage (LDES). Vanadium flow batteries and pumped hydro within domestic borders provide a buffer that no regional treaty can match.
- The Nuclear Elephant in the Room: You cannot run a modern industrial economy on intermittent solar and distant hydro alone. If ASEAN is serious about "decarbonizing" while maintaining security, the conversation must shift to Small Modular Reactors (SMRs). Vietnam and Indonesia know this, but they are too timid to say it loudly while the "regional grid" hype train is in the station.
- Microgrid Resilience: True security comes from a "cellular" energy architecture. If one part of the system fails or is sabotaged, the rest stays up. A centralized regional grid is a single point of failure.
The Price of Interdependence
I have consulted for firms that lost millions betting on cross-border infrastructure that never materialized because a local election changed the political winds. In 2021, Malaysia banned the export of renewable energy to Singapore to prioritize its own domestic targets. They eventually eased it, but the message was clear: domestic politics trumps regional "synergy" every single time.
Investors are being told that the APG will create a "liquid market" for electricity. This is a misunderstanding of how Southeast Asian utilities operate. Most are state-owned or heavily regulated monopolies. They do not want liquid markets; they want controlled, predictable margins and social stability. A regional market would force a convergence of prices that would be politically radioactive in lower-income member states.
The "People Also Ask" Reality Check
Does a regional grid lower costs? Only in a vacuum. Once you factor in the "sovereignty premium"—the cost of building redundant backup systems for when your neighbor cuts you off—and the astronomical insurance costs for trans-border assets, the "savings" evaporate.
Is it better for the environment? Not necessarily. It encourages "carbon leakage," where wealthy nations outsource their environmental impact to poorer neighbors. Singapore gets to claim "net zero" while Laos damns its rivers and destroys local ecosystems to feed the demand. It’s an accounting trick, not a climate solution.
What should we do instead? Stop trying to fix the 20th-century model of centralized, long-distance power. The Iran war threat proves that the old ways are fragile. The future belongs to the nation that can power itself entirely within its own borders using a mix of nuclear, deep-geothermal, and localized storage.
Every dollar spent on the ASEAN Power Grid is a dollar stolen from the only thing that actually provides security: self-sufficiency. Stop building bridges to people who will burn them the moment they get cold.
Build your own furnace.
