Data sources

Where the data comes from

Every public dataset behind the map, the plant panel, the agent and the MCP server: who publishes it, what it feeds in InfraMap and how current it is.

Updated October 25, 2026

At a glance

Each dataset keeps its own reporting period, so the latest month differs by source. Panels and tool results always state the period they cover. How InfraMap combines these sources is on Methodology.

  • Updates. Archives run through September 2026. A scheduled collector adds recent hours for every market through the day and revisits recent days until final prices replace preliminary ones.
  • History. Start months are market-wide. Each node’s history starts when the ISO first published it. Nodes added in the October 2026 coverage review were backfilled from January 2023 (PJM from April 2023, CAISO from October 2023).
  • Map periods. The Prices layer covers January 2025 to August 2026 by week, month and year.
  • Known gaps stay blank, for example some NYISO real-time days in July 2026 and some SPP five-minute files.

Pricing-node and hub registries

CAISO, ERCOT, ISO-NE, MISO, NYISO, PJM, SPP, EIA and FERC

Used to decide which node prices each plant, its comparison hub and its price chain: ISO node, resource and hub registries (for example CAISO OASIS node and resource lists, ERCOT settlement point and resource registries, ISO-NE CELT, the NYISO Gold Book, PJM hub definitions and SPP settlement location reports), EIA-860 node fields, and FERC EQR delivery points. Node locations on the map come from published coordinates where available; MISO locations come from a reviewed catalog and are labeled unverified.

Served
Node coverage review of October 16, 2026; price chains of October 22, 2026

How nodes, hubs, basis and price chains are assigned is on Methodology.
