It is an issue where the electric utilities are owned by non-frum Jews and hire Jewish workers to run them. That is an issue in Eretz Yisrael since if you make use of the government’s electric supplier, you are in effect hiring Jews to do malacha for you on Shabbos.
An alternative is not to use electricity on Shabbos (note that no gedolim used electricity on Shabbos prior to the late 19th century or early 20th century), or to use only batteries and one’s own generator (if it can run safely without human involvement), or to have one’s own generator and hire a non-Jew to run it.
