Prior state
Many national grids remained fragmented, with limited interconnections and high curtailment of renewable output.
Material change
Multi-country power pools expanded both physical capacity and market rules, enabling seasonal and diurnal balancing across larger geographic domains. New high-voltage direct-current corridors linked resource-rich zones to demand centers.
Why now
The cumulative build-out of variable generation in the 2050s and 2060s produced chronic curtailment and reliability problems that national-scale balancing could no longer resolve at acceptable cost; simultaneous maturation of regional financing vehicles lowered the political barrier to shared corridors.
Mechanism and resistance
Resistance arose from national utilities defending monopoly positions and from security establishments wary of dependence on neighbors. Counter-pressure came from industrial users seeking lower prices and from climate-finance institutions conditioning support on regional integration.
Consequences
Average wholesale prices fell in surplus regions; reliability improved in deficit regions; political leverage shifted toward corridor-host jurisdictions.
End state
Regional power pools handled a majority of cross-border electricity trade in the named continental domains and set the de-facto reliability standards for connected national systems.
Observable test
Official market reports show more than half of inter-country electricity transfers occurring under regional-pool rules rather than bilateral contracts in at least two of the named continental domains.
Disconfirming sign
Persistent national-grid isolation and high renewable curtailment rates despite available transmission technology.
