Spot power prices at PJM’s Western hub exceeded $1,021 per megawatt-hour due to supply constraints. Bloomberg reported that PJM issued a Maximum Generation Alert with approximately 62,000 megawatts of generation offline for planned maintenance. According to Oilprice.com, the supply-demand imbalance created significant stress on the grid serving millions of customers.

The price spike occurred as an unseasonable heatwave across the US Midwest and Mid-Atlantic boosted demand while generation capacity was restricted for seasonal upkeep. The grid faced challenges in maintaining reliability as power commitments to warmer southern and western regions further reduced available cushions, causing spot prices to trade at more than double the day-ahead average.
