Overview

PJM's verified real-time locational marginal prices at hourly granularity for every pricing node, with total LMP and its system-energy, congestion, and marginal-loss components in dollars per MWh. These are the settled, authoritative real-time prices — published on roughly an 18-hour lag behind the operating hour — and history reaches back to 2018, making this the table for real-time price history, day-over-day basis, and volatility studies. For prices in the current hour use the unverified 5-minute feed instead. Source: PJM Data Miner 2.

Use with MCP

This table is readable two ways, over the same guarded boundary. Over HTTP: POST /api/v1/datasets/pjm_rt_hrl_lmps/query, described in the API reference. Or from an MCP client: connect a market below, then use search_data or describe_data to load its query contract before calling query_data.
