Topic | Long-term planning time horizon |
---|
PJM LTRTP | 15 years forward |
---|
Order 1920 | 20 years forward |
---|
What must PJM do? | PJM must look 5 years further into the future |
---|
|
Topic | Planning cycle frequency |
---|
PJM LTRTP | Every three years |
---|
Order 1920 | Every five years at most |
---|
What must PJM do? | No change required |
---|
|
Topic | Number of scenarios |
---|
PJM LTRTP | Three |
---|
Order 1920 | Three minimum |
---|
What must PJM do? | No change required |
---|
|
Topic | Number of sensitivities |
---|
PJM LTRTP | No specific number |
---|
Order 1920 | At 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 |
---|
|
Topic | Scenario inputs |
---|
PJM LTRTP | PJM has included policy mandates and goals, a limited set of resource retirements, and queue interconnection requests |
---|
Order 1920 | List 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). |
---|
|
Topic | Benefits |
---|
PJM LTRTP | Proposes four to be used for project selection: Production cost savings, avoided generation investment, avoided transmission investment, and reduced loss of load |
---|
Order 1920 | Lists 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. |
---|
|
Topic | Cost allocation |
---|
PJM LTRTP | Proposes 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 1920 | Requires 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). |
---|
|
Topic | Alternative Transmission Technologies |
---|
PJM LTRTP | PJM makes no mention of these |
---|
Order 1920 | Mandates 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. |
---|
|
Topic | Right-sizing |
---|
PJM LTRTP | To a limited extent, PJM analyzes regional projects to see if they replace the need for local projects |
---|
Order 1920 | Mandates 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. |
