"We will fund up to 30 million LED bulbs for Ukraine, for precious energy savings," Ursula von der Leyen said in a tweet.
"When 50 million of these bulbs are deployed with our partners, this will save 1 GW - the annual output of a nuclear plant," she added.
"In times of darkness, we stand with our Ukrainian friends," von der Leyen also tweeted.
In a separate post, she said: "The Ukrainian spirit remains unbroken. Unyielding. We will help the Ukrainian people as long as necessary. We have already mobilised 800 generators. Now Europe is providing more support to help Ukraine get through the winter."
Since early October, Russia has targeted Ukraine's critical energy infrastructure, including power plants, transmission and distribution facilities and water pumping stations, leaving millions of people without power, heat or water, the Reuters news agency has reported.
Ukraine's allies meeting in Paris on Tuesday pledged over EUR 1 billion worth of aid to help Ukrainians survive the winter amid a humanitarian crisis, news outlets reported.
Tuesday is day 293 of Russia’s war on Ukraine.
