Grid Politics and Cross-Border Energy
How electricity grids connect nations, create interdependencies, and become tools of political leverage.
Connected Grids, Connected Politics
Electricity grids rarely respect national borders. Europe's grid connects 40 countries from Portugal to Turkey. The Nordic countries share electricity seamlessly, with Norwegian hydropower balancing Danish wind. The Southern African Power Pool connects 12 nations, with South Africa's Eskom providing baseload power to neighbors. These interconnections improve efficiency, enhance reliability, and lower costs -- but they also create political dependencies.
When countries depend on each other for electricity, energy policy becomes foreign policy. France exports nuclear electricity to neighbors, giving it influence over European energy debates. Russia's grid connections to the Baltic states were designed during the Soviet era to maintain Moscow's leverage. In 2024, Lithuania, Latvia, and Estonia completed a decade-long project to synchronize their grids with continental Europe, physically disconnecting from the Russian-controlled system -- a technical project driven entirely by geopolitics.
