On Feb. 24, 2022, Ukraine's grid operators were entering into "island mode"—a state of autonomy from other neighboring grid systems—when their country was invaded by Russia. This shift was a test that was part of plans already underway for months to desynchronize from the Russian. .
Ukraine's aging grid has been a challenge to maintain even before the war brought targeted attacks. Before the invasion, NREL was. .
"So much of that planning went to the back burner after the invasion," said NREL researcher Ilya Chernyakhovskiy. "Then, the focus became:. .
Looking further into the future, NREL and USAID are planning to help Ukraine and its power system operators build a cleaner and more resilient energy system. But this will take time, as. [pdf]
