Data Availability

Data Locations

PJM is consolidating its publicly available data into the Data Miner 2 tool.

While most of this data is currently available in Data Miner 2, it will also continue to be available on to give PJM members time to update their systems and processes that use PJM data.

If you cannot find the data you are seeking, PJM may still be in the process of converting the data. The Data Directory provides a searchable list of the legacy data and locations.

Confidential Data

In general, PJM may not post or disclose confidential data. This includes:

Individual Generator Output: The output of an individual generator is considered confidential, including output at a single point in time, over an hour, over a year, etc.

Nodal Load: The load at an individual location (node, pnode, etc.) is considered confidential, including load at a point in time, over an hour, over a year, etc.

Capacity Commitments: Any commitments in the RPM Capacity Market are confidential.

Individual Generator Outages: Individual generator outages are generally considered confidential. PJM only releases aggregated information on such outages.

Individual Generator Offers: The Federal Energy Regulatory Commission requires that PJM post all supply offers on a four month delay. These offers are masked to prevent identification of individual generators. Any unmasked or more detailed information in considered confidential.

These are examples of the most commonly requested confidential information. Consult Manual 33 Section 3.5 for more information on the confidential information.
