A model says deeper Latin American grid integration could save $32 billion a year around 2045
The study, published 17 September 2026, finds continued fragmentation can raise system costs by up to 7% and weaken resilience to drought shocks.
Integration would let regions share hydropower, solar, wind and firm generation when weather and demand differ across borders.
What $32 billion means
It is the annual system-cost gap between model scenarios near 2045, not an equal household rebate or guaranteed yearly saving.
Drought link
Hydropower exposure makes low reservoirs disruptive. Cross-border transmission can spread risk across different weather zones and generation mixes.
Beyond engineering
Tariffs, market rules, trust, emergency exchanges and cost sharing are as important as wires. Low trust can concentrate gains in small blocs.
Limits
Demand, fuel prices, construction costs and drought severity may differ. A least-cost route does not automatically resolve land, Indigenous-rights or environmental issues.
