Regional Transmission Expansion Plan (RTEP)
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.
Regulators are encouraged to participate in the ongoing activities of the
PJM Transmission Expansion Advisory Committee (TEAC). This forum provides opportunity for stakeholder participation and advice throughout the
RTEP process and for remaining apprised of all evolving aspects of PJM’s
RTEP plans and processes.
The Sub Regional RTEP Committees (SRRTEP) provide a forum to review Subregional
RTEP upgrades and to provide input and recommendations to the TEAC:
PJM’s RTEP Report The
RTEP report is published annually by PJM to convey the results of planning studies throughout the previous calendar year and to explain the rationale behind why
transmission system upgrades are needed. The report discusses system drivers, reliability criteria violations and upgrades for reporting purposes to facilitate greater
RTEP understanding.
A complete list of all approved
RTEP upgrades, a brief description of facility and driver, as well as,
construction status is available .
Organization of PJM States Incorporated (OPSI) OPSI is a liaison group to PJM and its members. It is a non-profit group made up of the state regulatory commissions from the states in which PJM operates.

Reliability Planning Process Working Group (RPPWG) The
PJM Regional Planning Process Working Group (RPPWG) enables a stakeholder process to evaluate and make recommendations to the
PJM Members Committee to reform the present interconnection queue and study processes.
PJM Planning Process Protocol The
PJM Operating Agreement (PDF), Schedule 6, codifies the provisions under which PJM executes its Regional Transmission Expansion Planning Protocol, known as the PJM
RTEP Process.
PJM’s Open Access Transmission Tariff (OATT)
PJM’s
OATT describes the interconnection request process for generating resource interconnection and merchant transmission interconnection, as well as, specific process provisions to address long-term firm transmission service and Auction Revenue Rights.
PJM M-14 Series of Manuals PJM’s
M-14 series of manuals describe the specific business rules under which PJM effects the entire
RTEP Process including details associated with the scope and procedures associated with the planning process methodologies, analyses and development of proposed upgrades.
Load Growth and Forecasting One of the core principles of PJM’s planning process is the integration of all drivers that impact grid infrastructure planning needs and all solutions available to meet those needs. Load Forecasting is a fundamental, key driver of resource adequacy requirements and transmission expansion plans.

Planning Criteria In developing the RTEP, PJM annually performs comprehensive power flow, short
circuit and stability analyses. These assess the impacts of forecasted firm loads, firm imports from and exports to neighboring systems, existing
generation and transmission assets, and anticipated new
generation and transmission facilities. PJM conducts a comprehensive assessment of the ability of the PJM system to meet all applicable reliability planning criteria.
