Ukraine's Zaporizhstal steel plant suspended production after a complete power outage caused by Russian attacks on energy infrastructure. The Metinvest-owned facility in Zaporizhzhia represents a critical component of Ukraine's industrial base. Russian strikes have systematically targeted power generation facilities and transmission networks since autumn 2022. Steel production requires stable, high-voltage electricity supplies that cannot be replaced by backup generators. The suspension affects workforce employment, supply chains, and Ukraine's economic resilience during wartime conditions.
