PJM conducts long-range planning studies and analyzes future demands on the transmission system in our region that serves 65 million people. These studies identify changes and additions needed to ensure grid reliability for the future. This process culminates in the PJM annual Regional Transmission Expansion Plan. Visit the PJM Learning Center to learn more about what “planning” means at PJM.
