Ukraine has been working toward connecting to the European power grid for years, but Russia’s invasion made the situation urgent. Engineers achieved “a year’s work in two weeks.”
On February 24 Ukraine’s electric grid operator disconnected the country’s power system from the larger Russian-operated network to which it had always been linked. The long-planned disconnection was meant to be a 72-hour trial proving that Ukraine could operate on its own. The test was a requirement for eventually linking with the European grid, which Ukraine had been working toward since 2017. But four hours after the exercise started, Russia invaded.
After the late February trial period, Ukrenergo, the Ukrainian grid operator, had intended to temporarily rejoin the system that powers Russia and Belarus. But the Russian invasion made that untenable. “That left Ukraine in isolation mode, which would be incredibly dangerous from a power supply perspective,” Jayanti says. “It means that there’s nowhere for Ukraine to import electricity from. It’s an orphan.
Crucial to this mission is grid interconnection. Linked systems can share electricity across vast areas so that a surplus of energy generated in one location can meet demand in another. “More interconnection means we can move power around more quickly, more efficiently, more cost effectively and take advantage of low-carbon or zero-carbon power sources,” says James Glynn, a senior research scholar at the Center on Global Energy Policy at Columbia University.
One safeguard against grid instability is inherent to many of Ukraine’s assets: rotational inertia. Once heavy turbines, such as those in the nuclear plants that comprise much of Ukraine’s energy supply, are spinning at a certain frequency, it takes a substantial, sustained change in power to alter their rotation. They are unaffected by minor blips in the power generated to spin them, so their frequency remains stable.
