Life Inside Ukraine’s Blackouts as Temperatures Plummet
The Wall Street Journal· 2026-02-09 14:15
I'm in the center of Kiev, Ukraine. Today, the temperature dropped to minus14°. This is the coldest winter Ukraine has faced since the start of Russian full-scale invasion.It's only early evening, but the city is already dark. Over the past weeks, the situation with electricity, heating, and water has been extremely difficult. Russia is attacking Ukraine's energy infrastructure to push the country into a blackout.Millions of people across Ukraine are affected every day and the dogs as well. Outside the city ...

Engineer Explains Three Key Issues in Renewable Grid Design

Grid Infrastructure Challenges with Renewable Energy - Renewable energy sources like wind and solar are creating infrastructure problems because power grids weren't designed for them [1] - The lack of inertia in renewable energy systems can increase the risk of widespread blackouts [5] - Conventional power plants have built-in inertia, providing buffer time when a power plant fails [2][4] Solutions for Grid Resilience - Grid-forming inverters can operate independently and support the grid during disruptions [5][6] - Synchronous condensers can provide additional rotational inertia by using electricity from renewable sources [7] - Battery energy storage systems (BESS) can deploy excess energy to stabilize the grid during outages [8] Technological Aspects - Conventional power plants produce electricity at a grid frequency of 60 Hz in the US [3] - Grid-following inverters rely on the grid's voltage and frequency, while grid-forming inverters can adjust electronically and react faster [5][6]
