The Ukraine electric grid has been synched with the Russian electric grid since the fall of U.S.S.R. In 2017, Ukrain and ENTSO-E (Continental Europe electric grid authority) began planning to interconnect the Ukraine grid with the Europe Grid (and disconnect from the Russian grid). The original schedule was testing throughout 2022, and interconnecting the grids in 2023. NPC UKRENERGO announced as of yesterday (March 16, 2022), it has synched with the Continental Europe grid a year ahead of schedule. https://www.linkedin.com/feed/update/urn:li:activity:6910298679274815488 https://time.com/6153039/ukraines-electricity-grid-escape-russia/
