PJM’s Regional Transmission Expansion Plan (RTEP) identifies transmission system additions and improvements needed to keep electricity flowing to 51 million people throughout 13 states and the District of Columbia. Studies are conducted that test the transmission system against mandatory national standards and PJM regional standards. These studies look 15 years into the future to identify transmission overloads, voltage limitations and other reliability standards violations. PJM then develops transmission plans in collaboration with Transmission Owners to resolve violations that could otherwise lead to overloads and black-outs. This process culminates in one recommended plan – one RTEP – for the entire PJM footprint that is subsequently submitted to PJM’s independent governing Board for consideration and approval.

Generation Interconnection Queues:  View active and withdrawn requests.	RTEP Construction Status:  View a full listing of all planned upgrades and their status.
Planning Criteria:  View standards by which PJM identifies needed upgrades.

Transmission Owners:  Transmission Owners (TOs) and PJM work together to facilitate the coordination of planning and operation of Transmission Facilities within the PJM Region.

Regulators:  PJM’s region-wide RTEP process applies planning and reliability criteria over a fifteen-year horizon to identify transmission constraints and upgrades to alleviate them.

Developers:  PJM administers the process for the interconnection of all new generation and merchant transmission facilities within the PJM footprint.
