Interregional Planning

PJM participates in collaborative interregional planning activities with its neighbors:

• Northeast: New York Independent System Operator (NYISO) and ISO New England
• West: Midcontinent Independent System Operator (MISO)
• Southeast: Southeastern Regional Transmission Planning (SERTP) and North Carolina Transmission Planning Collaborative (NCTPC)

These planning efforts have grown alongside the evolution of broader organized markets and interest at the state and federal level in favor of increased coordination, particularly along interregional seams. Studies examine the impacts of respective regional transmission plans, generation interconnection requests and opportunities for economic efficiency.
