“Opposition at the electricity frontier”
German grid operator 50Hertz is installing phase shifters to stop excess electricity from spilling over into neighbouring countries like Poland, writes Andreas Mihm in Frankfurter Allgemeine Zeitung. Electricity current normally takes the path of least resistance, but if the direct route is congested it will take a detour, sometimes through neighbouring countries. These loop flows have caused diplomatic controversies in the past, writes Mihm. The phase shifters – some of which have already been installed near the Polish-German border – can raise electrical resistance to divert power elsewhere.
