nodal prices

Prices quoted at individual grid locations (pricing nodes or PNodes) rather than as one system-wide number.

CAISO OASIS carries nodal detail across every PNode plus trading hubs and load aggregation points, and PJM reports by pricing node, hub, interface, transmission zone and load area.

In this catalog it appears concretely: - CAISO OASIS coverage — "nodal detail across all PNodes, trading hubs (NP15, ZP26, SP15) and load aggregation points". - PJM coverage — "reported by pricing node, hub, interface, transmission zone and load area".

Conventions decide whether two sources can be joined at all. Buy one side of an analysis that ignores this convention and every reconciliation step — calendar alignment, unit conversion, entity matching — lands on your team instead of the vendor's.

The failure mode is concrete: the label appears in a listing, the delivered files tell a different story, and the gap surfaces mid-project when fixing it is most expensive.

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 CAISO OASIS coverage lets you inspect the real artifact before any budget is committed.

Treat every claim of this attribute as testable:

1. Open CAISO OASIS coverage and confirm its record — "nodal detail across all PNodes, trading hubs (NP15, ZP26, SP15) and load aggregation points" — against the files you actually receive.
2. Open PJM coverage and confirm its record — "reported by pricing node, hub, interface, transmission zone and load area" — against the files you actually receive.
3. Pin down update cadence in writing. Across this catalog, 22.6% of 1,744 datasets refresh daily and 64 still arrive only through a manual request form, so ask exactly how fresh each release is.
4. Check whether definitions are verified at all. Field definitions are verified for 1495 of 1,744 datasets (85.7%), and any source you license should meet that bar.
5. Price the delivery route before the license. In this catalog bulk download is the most common access method (725 datasets) ahead of official APIs (574), and 379 sources still require scraping — a maintenance cost that lands on you, not the vendor.
