Cross-border grid fault plunges Ukraine and Moldova into blackouts

A technical malfunction on high-voltage lines linking Ukraine, Moldova and Romania caused cascading power outages across seven Ukrainian regions and Moldova, with power restored later the same day. Kyiv’s metro paused and heating was limited for thousands amid freezing temperatures. Officials said there was no cyberattack or direct war damage, and investigators are probing the cause while imports are being increased to meet demand.

Ukraine hit by cascading grid failure as mass blackouts sweep major cities

A cascade shutdown in Ukraine’s power grid triggered emergency blackouts across Kyiv and several regions after transmission-line disruptions, cutting heating and water in freezing conditions as officials and energy workers race to restore power to critical infrastructure; Moldova experienced outages and Kyiv metro services were interrupted as the system stabilizes.

Ukraine’s Winter Energy Fight: Residents Rewire Homes to Beat Blackouts

Kyiv and other Ukrainian cities face up to 20 hours of daily power outages as Russia targets energy infrastructure, but residents and local Condominium Owners Associations (OSBBs) are hardening homes with energy-efficient heating units, rooftop solar stations, and local batteries to keep heat and essential services running. Kyiv supports OSBBs with a 70/30 funding split, enabling upgrades like insulated pipes, new pumps, LED lighting, and balanced batteries that power elevators, internet, and lighting during outages. In parallel, households rely on large battery systems, portable power banks, gas heaters, and fuel-switching to cope, while the broader grid retains functionality thanks to durable CHP plants and high air-defense success against drones and missiles. The result is warmer homes (often above 20°C) and continued operation of transport, services, and commerce despite severe winter attacks and climate conditions.

Ukraine declares energy emergency as Kyiv braces for winter power cuts

President Zelensky declared a state of emergency in Ukraine's energy sector after Russian strikes damaged power infrastructure and subzero weather left Kyiv and other regions without electricity, heating, or water. A round-the-clock task force will coordinate the response, with Energy Minister Denys Shmyhal leading efforts to restore supplies, ramp up imports of electricity, and connect backup equipment to the grid. The government will streamline procedures and review curfews to keep invincibility points open, while authorities and energy workers work around the clock to mitigate outages during the crisis.

Tesla Robotaxis Remain Operational During San Francisco Power Outage, Musk Confirms

Waymo has temporarily suspended its driverless ride-hail service in San Francisco due to a widespread power outage caused by a substation fire, while Tesla's ride-hailing service, which requires human drivers, remains unaffected. The outage affected about 130,000 residents, and the situation highlights ongoing challenges and competition in autonomous vehicle services.
