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 PJM.com 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.

Unavailable Data

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.
