PJM Data Miner 2

PJM's API front end for wholesale market and grid operations data, gated behind a PJM Tools account and integration key.

Members get up to 600 data connections per minute versus 6 for non-members, requests return up to 50,000 rows, and non-members may not republish data or derivatives without at least an Associate Membership.

In this catalog it appears concretely: - licensing license — "PJM Data Miner 2 Acceptable Terms of Use (proprietary)". - terms_notes — "gated behind a PJM Tools account and integration key'; 'members may not exceed 600 data connections per minute and non-members 6 per minute". - estimated_size — "API returns up to 50,000 rows per request".

Access method sets your maintenance bill. Delivery routes change, layouts drift and scrapers rot quietly; whoever operates your pipeline inherits all of it, which is why access should be priced alongside the license itself.

The failure mode is concrete: a source can carry the PJM Data Miner 2 label while differing from what you need on exactly the dimension that matters — PJM Data Miner 2 Acceptable Terms of Use (proprietary). Comparing two sources on that line usually settles the choice faster than any feature matrix.

You rarely have to take a vendor's word for it. 82.4% of the 1,744 datasets Datadory catalogs are free to access, and licensing license lets you inspect the real artifact before any budget is committed.

Treat every claim of this attribute as testable:

1. Open licensing license and confirm its record — "PJM Data Miner 2 Acceptable Terms of Use (proprietary)" — against the files you actually receive.
2. Open terms_notes and confirm its record — "gated behind a PJM Tools account and integration key'; 'members may not exceed 600 data connections per minute and non-members 6 per minute" — against the files you actually receive.
3. Open estimated_size and confirm its record — "API returns up to 50,000 rows per request" — against the files you actually receive.
