Asia's $15 trillion energy build-out meets weak grids and a post-Hormuz shock

Asia needs about $1 trillion a year in energy infrastructure over 15 years, according to a new estimate. Earlier 2026 events, including the Strait of Hormuz closure and grid-limited project cancellations, show how hard that build-out may be.

What happened

An analysis published on 25 October 2026 says Asia is building what could become a $15 trillion energy market. It puts the continent's infrastructure investment need at $1 trillion a year over 15 years. [1] Asia would account for 70% of global net energy demand growth through 2040. [1]

The analysis expects coal to stay the dominant fuel for longer than previously thought, even as renewables grow. [1] McKinsey projects $300 billion a year for wind and solar. [1] India and Indonesia are also pushing biofuel mandates, with E30 ethanol and B50 biodiesel. [1] Indonesia's B50 programme is estimated to cut fuel imports by $9.4 billion and emissions by 44 million metric tons annually. [1]

How we got here

The investment story has been building for almost a year. In December 2025, Chinese firms were reported to have put $80 billion into global clean energy in the year to November 2025, a 60% annualized increase. [2] Trade tariffs and China's dominance in solar, wind and EV batteries were cited as drivers. [2] Southeast Asia led as a destination, with major battery plants in Indonesia. [2] China controls about 95% of polysilicon and wafer supply. [2]

Early 2026 pointed to both opportunity and strain. On 13 January, Brent was around $65 per barrel, lifted by geopolitical risk despite limited physical supply losses. [3] On 26 January, Indian LNG importers were reported to be stalling long-term negotiations for over a year. They expected a supply glut later in 2026 to bring lower prices. [4] Global LNG supply was expected to rise by about 10% that year. [4] The IEA projected growth of more than 7%, the fastest since 2019. [4] On 23 February, India's NITI Aayog projected that coal demand could more than double to 2.615 billion tons by 2050 under current policies. [5] The same report said grid investment must rise 50% from the current $400 billion annually to meet demand growth through 2030. [5]

Then came the shock. The Strait of Hormuz was closed in February 2026, cutting 20% of global oil and gas flows and hurting Southeast Asian importers. [6] Since the Iran war began that month, more than 30 governments have introduced renewable energy, EV and efficiency measures. [7] Brent crude rose above $100. [7] The Philippines faced rationing and a national emergency. [8]

The response has been uneven. Solar generation reached 2,811 TWh in 2025 and passed wind's 2,714 TWh for the first time. [9] Renewables supplied 33.4% of global electricity. [9] Yet total energy demand grew faster than low-carbon supply additions, so renewables are still layering onto the existing system. [9] In the first half of 2026, global greenhouse gas emissions rose 0.2%. [7] Wind and solar investment fell globally, mainly because of a slowdown in China. [7] That contrasts with the strong 2025 Chinese outbound investment figure. [2][7]

In Southeast Asia, 50–60% of renewable projects in Vietnam, Thailand and Indonesia stalled or were cancelled in 2021–2025 because of aging, overburdened grids. [6] Over 100 TWh of new demand is expected by 2030. [6] Grid builds take 5–15 years. [6] An October report added that this demand could arrive within 1–3 years, and that the Strait is reopening. [8] In September, a study projected that global biofuels output could rise nearly 70% by 2030 as mandates tighten in the U.S., EU, Brazil, India and Indonesia. [10] Full implementation could add roughly 36 million hectares of feedstock land. [10] Researchers warned of medium-term food insecurity and price pain for low-income households. [10]

Why it matters for markets

The 25 October estimate would imply sustained demand for grid equipment, generation capacity, fuels and financing across Asia. [1] The grid-investment gap flagged in February suggests that transmission, not generation, could set the pace. [5][8] If grid delays continue, clean energy capital could be deterred and exposure to future energy shocks could persist. [6][8]

Fuel markets could feel mixed effects. Coal's longer role could support continued demand for it. [1][5] Rising LNG supply could pressure U.S. exporter margins while helping price-sensitive Asian importers. [4] Larger biofuel mandates could cut import bills in Indonesia. [1] They could also push up food-related costs for net food importers. [10] The Hormuz disruption showed how quickly oil prices can react to supply risk. [6][7]

Interest rates and currencies do not appear to be a direct channel for this story, so they are left out.

What to watch

• Whether grid investment rises from $400 billion annually toward the 50% increase cited for 2030. [5]
• Whether stalled projects in Vietnam, Thailand and Indonesia restart as grid capacity improves. [6][8]
• Whether the reopening of the Strait of Hormuz holds. It is not yet known how quickly regional energy security would recover. [8]
• Whether wind and solar investment recovers after the first-half 2026 decline tied to China's slowdown. [7]
• Whether the expected LNG supply increase brings lower prices and more long-term contracts by Indian importers. [4]
• How India and Indonesia implement their ethanol and biodiesel mandates, and how food-price concerns are handled. [1][10]
• Whether emission cuts from the new government measures become measurable. Experts say this may take years. [7]
