Note: Changes to machine capabilities or in-service dates as originally submitted in the Impact Study Agreement (PJM Open Access Transmission Tariff Attachment N) must be formally communicated to the appropriate PJM project manager.

This form is to submit data for proper modeling of your respective Queue Project in the Impact Study phase.

Impact Studies are conducted to identify transmission expansion needed to maintain the system reliability given the addition of your generation on to the network.

The data that is submitted is required to perform the power flow, short circuit and dynamic simulation analyses which are necessary for the Impact Study phase.

PJM uses the following programs to perform the Impact Analysis:

1. PSS/E from PTI, Inc. (power flow and dynamic simulation)
2. Aspen from Advanced Systems for Power Engineering, Inc. (short circuit))

Minimum requirement fields are indicated by *

All data must be provided on an individual unit basis.

For example, a combined cycle plant with two identical Combustion Turbines (CT) and one Steam Turbine (ST) would have two submissions of the data request form. One submission for the CT and one submission for the ST.

If the final unit specifications are not certain an approximation must be made.

When more information is available, the typical model must be replaced with an “as built” model based on the actual unit purchased.

If data is still not available and cannot be estimated please indicate by typing:

• TBD and MM/DD/YY

The date indicates when you will supply us with the expected data.
