Data Requirements for PJM RTEP Feasibility Studies

This form is not to be used to submit changes in project MW size or estimated in-service dates. Changes related to project MW size or in-service dates must be officially submitted to the assigned project manager.

This form is not to be used to submit data for existing generator projects. The form listed in Manual 14C known as Generator As Built Data Form is to be used instead.

This form is to submit data for proper modeling of your respective queue project in the Feasibility Study phase.

Feasibility Studies are conducted to identify transmission expansion needed to maintain the system reliability given your generation onto the network.

The data submitted is required to perform the power flow, and short circuit analysis which are necessary for the Feasibility Study phase.

PJM uses the following programs to perform the feasibility analysis:

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

Minimum requirement fields are indicated by *. Failure to provide the necessary data prior to the project kick-off meeting will result in withdrawal of the project from the queue.

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.

When more information is available, the typical model must be replaced with a detailed 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

Note: Please do not include special characters in the fields below (e.g. %, /, *, !, etc).
