A looming “super” El Niño is poised to disrupt global energy markets, forcing India to turn back to thermal coal to plug a massive looming power deficit. The climate phenomenon, which typically triggers devastating agricultural losses, carries a lucrative silver lining for global miners if they can get their product to port.
The mechanism driving this surge is starkly straightforward. El Niño weather patterns traditionally suppress wind speeds and dry up rainfall across South Asia. For India, the world’s second-largest coal consumer, this translates to crippled output from wind farms and hydroelectric dams. Coupled with soaring temperatures that drive air conditioning demand, New Delhi faces an estimated generation gap of nearly 18 terawatt-hours (TWh).
“When the wind stops blowing and the reservoirs dry up, the green transition takes a backseat to keeping the lights on,” says a senior energy analyst tracking South Asian power grids. “Renewables are expanding rapidly in India, but in a climate crisis, coal remains the ultimate backstop. Something has to fill that 18 TWh void, and that something is fossil fuel.”
India still relies on coal for roughly 60% of its electricity generation. The impacts are already leaking into current data: coal-fired generation recently surged 14% year-on-year to 178 TWh as unusually hot, dry weather took hold. Far from weaning itself off the fuel, India’s long-term appetite could see demand more than double to 2.6 billion tonnes by 2050, up from 1.26 billion tonnes in 2025.
For South African exporters, this should be an easy win. India is already the single largest buyer of South African thermal coal, absorbing 25.75 million tonnes in 2025 roughly 45% of the country’s total shipments. Indian independent power producers and sponge-iron manufacturers have grown hooked on South Africa’s highly competitive pricing. The resources are sitting waiting in the coalfields of Mpumalanga, Limpopo, KwaZulu-Natal, and the Free State.
The problem is getting it to the coast. South Africa’s export ambitions remain bottlenecked by its own crumbling infrastructure. The country’s coal corridor relies almost exclusively on Transnet, the state-owned rail and port operator plagued by years of locomotive shortages, cable theft, and degraded tracks. While rail volumes recovered slightly to top 50 million tonnes last year, they remain a far cry from the 75 million tonnes achieved just a few years ago.
“The inability to move coal from pit to port is no longer just a logistical headache; it’s a national balance-sheet crisis,” notes a Johannesburg-based bulk commodity strategist. “That 25-million-tonne shortfall represents roughly R150 billion ($8.2 billion) in completely foregone revenue that could have stabilized the broader economy.”
The crisis is perfectly captured at the Richards Bay Coal Terminal (RBCT), one of the largest facility complexes of its kind in the world. Engineered to handle a massive 91 million tonnes annually, RBCT moved just 57.66 million tonnes in 2025. Though it represents a 10% improvement as rail lines stabilized, the terminal is effectively operating at a staggering two-thirds of its intended capacity.
The window of opportunity will not stay open forever. Rival exporters in Indonesia and Australia are already moving aggressively to capture India’s looming demand shock, and India itself continues to build out renewable infrastructure at breakneck speed. South Africa retains a structural advantage in geographical proximity and pricing, but its Achilles’ heel remains the domestic value chain.
Market experts warn that capitalizing on the El Niño demand shock will require Transnet to rapidly expand private sector partnerships, automate its legacy networks, and overhaul inventory management. “El Niño is an act of God, but whether South Africa actually profits from it is entirely a matter of political will,” the strategist added. “The country doesn’t need another strategy document; it needs functioning trains.”
