PJM Triples Annual Load Growth Forecast, Driven by Data Centers and Electrification: PJM Interconnection, the manager of the country’s largest grid region, has tripled its forecast for electricity use in its territory through 2034, as Ethan Howland reports for Utility Dive. PJM says it is projecting substantial growth because of customers switching from fossil fuels to electricity and the anticipated growth of data centers. The new forecast says winter peak electricity use will have an average annual increase of 2 percent compared to 0.7 percent in its previous forecast. The rate of growth in electricity demand is a key variable in the transition to clean energy because it affects how quickly the grid needs to add new power plants, and it can lead to an increase in electricity prices, which may allow old power plants to justify remaining online.
