PJM LTRTPNo specific number
Order 1920At least one, applied to each scenario, to account for “uncertain operational outcomes” (e.g., extreme weather)
What must PJM do?PJM must include at least one sensitivity per scenario
TopicScenario inputs
PJM LTRTPPJM has included policy mandates and goals, a limited set of resource retirements, and queue interconnection requests
Order 1920List  of seven minimum required factors: Federal, state, Tribal, and local laws and regulations affecting the resource mix and demand; federal, state, Tribal, and local laws and regulations affecting decarbonization and electrification; state-approved Integrated Resource Plans (IRPs) and expected supply obligations for Load-Serving Entities (LSEs); cost, performance, and availability trends in generation, fuel, storage, building and transportation electrification technologies; resource retirements; generator interconnection requests and withdrawals; utility and corporate commitments and federal, state, Tribal, and local policy goals
What must PJM do?PJM must include additional factors based on FERC’s list and redesign scenarios to not be shaped around cost allocation methodologies or project drivers (e.g., reliability, public policy).
TopicBenefits
PJM LTRTPProposes four to be used for project selection: Production cost savings, avoided generation investment, avoided transmission investment, and reduced loss of load
Order 1920Lists seven required benefits that must be utilized to identify transmission needs: Avoided or deferred transmission facilities and aging infrastructure replacement, either reduced loss of load probability (LOLP) or reduced planning reserve margin (PRM), production cost savings, reduced transmission energy losses, reduced congestion due to transmission outages, mitigation of extreme weather events and unexpected system conditions, and capacity cost benefits from reduced peak energy losses
What must PJM do?PJM’s list of four benefits already captures benefits #1, 2, 3, and 7 from Order 1920. Benefits #4-6 can be incorporated by using different operational criteria during production cost modeling. PJM must also utilize benefits to identify transmission needs, not just evaluate proposed projects.
TopicCost allocation
PJM LTRTPProposes to use a combination of two existing PJM cost allocation approaches (regional cost socialization for baseline/reliability projects and State Agreement Approach for projects in medium/high scenarios)
Order 1920Requires each transmission provider to determine its own default cost allocation methodology in compliance with Order 1000, engaging states in its development during an initial 6-month Engagement Period prior to compliance. Allows states to develop an alternative State Agreement Process during this Engagement Period and any following planning cycle, if desired
What must PJM do?PJM can assist PJM transmission owners in launching the FERC-required 6-month Engagement Period with states to determine a default cost allocation methodology (and, optionally, State Agreement Process) prior to submitting a compliance filing to FERC next spring. This must be consistent with Order 1000 principles (invalidating the State Agreement Approach from consideration).
TopicAlternative Transmission Technologies
PJM LTRTPPJM makes no mention of these
Order 1920Mandates consideration of four ATTs (dynamic line ratings, advanced power flow controls, advanced conductors, transmission switching)  
What must PJM do?PJM does not propose solutions to transmission needs, but they can require transmission developers to include consideration of the FERC-mandated ATTs in their bids.
TopicRight-sizing
PJM LTRTPTo a limited extent, PJM analyzes regional projects to see if they replace the need for local projects
Order 1920Mandates consideration of right-sizing of assets as part of long-term planning
What must PJM do?PJM can require transmission developers to demonstrate consideration of right-sizing in their bids.
