Power Grid for 67 Million on Edge as Dire Cold Follows Storm.

The article focuses on the severe winter weather impacting the United States, which has led to a grid emergency declared by PJM Interconnection LLC, affecting 67 million people from New Jersey to Chicago. The extreme cold has resulted in record electricity demand, exceeding 147 gigawatts, and has caused significant disruptions, including power outages for over 1 million homes and businesses and a 12% reduction in the country's natural gas production. As temperatures are expected to drop further, PJM has activated emergency measures, including allowing power plants to exceed emissions limits and potentially utilizing backup generators. The ongoing cold snap poses risks of blackouts and challenges for power supply reliability. [Extracted from the article]
