PJM, the largest power grid operator in the United States, said on Friday that it is facing serious pressure on the electricity system.
The grid operator said it is working under a federal emergency alert to reduce electricity demand across its service area.
PJM said several problems are happening at the same time. Many electricity generators are currently out of service, reducing the amount of power available. High-voltage transmission lines are heavily overloaded, making it difficult to move electricity where it is needed, according to the report by Reuters. A long spell of extremely hot weather has led millions of people to run air conditioners, pushing electricity demand much higher than normal.
PJM has told utility companies to reduce electricity use among customers who have signed contracts to lower their power consumption during emergencies. These customers are usually large businesses or industrial users that agree in advance to cut electricity use when the grid is under stress.
PJM supplies electricity to about 67 million people, as per Reuters. Its power grid covers the Mid-Atlantic states, parts of the South, and the Washington, D.C., region.
PJM said it is unable to fully meet the expected electricity needs because of the current pressure on the grid, as stated by Devdiscourse. The company has started plans to manage and reduce electricity demand to keep the power system stable.
PJM said it is working closely with utility companies to reduce electricity use in a controlled way. The goal is to prevent the grid from becoming unstable and to keep electricity flowing safely across the region.
Residents and businesses in the affected areas have been advised to be ready for possible changes in electricity usage as PJM carries out its demand reduction plan. The company said these measures are aimed at protecting the reliability of the power grid.
Spot wholesale electricity prices in northern Virginia have climbed above $2,000 per megawatt-hour this week, as per Reuters. Under normal conditions, wholesale electricity prices in the PJM market are around $40 per megawatt-hour.
PJM's operational data say the biggest reason is congestion on high-voltage transmission lines. Because these transmission lines are crowded, it has become much more expensive to deliver electricity across the grid.
Prolonged hot weather has sharply increased the use of air conditioners across the region. This surge in electricity demand is adding more pressure to an already stressed power system.
To avoid bigger problems, the grid operator has started emergency demand reduction measures while wholesale electricity prices have jumped to unusually high levels.
