Dynamic Transfers

This page has information for generators outside of the PJM footprint that want to deliver its output into the PJM territory.

Background

When a generator within one balancing authority agrees to deliver power into another, it can choose to electrically transfer its output into the attaining balancing authority and thereby make itself available for dispatch by the attaining balancing authority. This is called a dynamic transfer.

The below graphic displays how power moves in a dynamic transfer.

Dynamic Transfers

As a dynamic transfer, a unit can elect to either dynamically schedule or pseudo-tie into an attaining balancing authority.

Dynamic Schedule

This is a reading or value used to schedule generation, often jointly-owned, between balancing authorities. It is subject to North American Electric Reliability Corporation tagging rules.

A unit may decide to Dynamically Schedule, instead of Pseudo Tying, because the owner does not hold long-term firm transmission service.

Pseudo Tie

This is a reading or value used as a “virtual” connection to a grid operator when no physical tie exists. The native balancing authority removes the unit from its calculations to schedule generation, and the attaining balancing authority adds it to its own. Pseudo ties currently are not subject to NERC tagging rules, but must register with the North American Energy Standards Board to assist with inter-regional congestion management.

A unit may decide to Pseudo Tie, instead of Dynamically Scheduling, because the resource is seeking a Capacity Import Limit exception in PJM’s Reliability Pricing Model.
