Overview

View hourly LMP data for a pricing node across multiple days (up to 60). Each day displays as a compact box with hourly DA/RT prices and spreads.

Selectors

• Pricing Node: Type to search (predictive autocomplete) or pick from the list. The name must exist — unknown names are rejected
• End Date: The most recent date to include
• Days: Number of days to load (1-60), counting back from end date

Table Columns

• HE: Hour Ending (1-24)
• DA LMP: Day-Ahead total LMP
• RT LMP: Real-Time total LMP
• Spread: DA - RT price difference
• DA CC: Day-Ahead congestion component
• RT CC: Real-Time congestion component
• °F / mph: Temperature and wind at the node's nearest NOAA airport (zone-level approximation; hover the mph cell for wind direction). Coverage is sparse — hours without observations show a dash
• N °F / S °F / IL °F / IN °F / MI °F / AR °F: Footprint-wide reference temperatures (identical across nodes). MISO North (Minneapolis, KMSP) and South (New Orleans, KMSY) sit beside the node-local °F; the Illinois (Chicago, KORD), Indiana (Indianapolis, KIND), Michigan (Detroit, KDTW) and Arkansas (Little Rock, KLIT) hubs follow at the right. Lets you read the regional temperature spread that drives the seasonal load/price separation from any node
• DA Ld / RT Ld: MISO system day-ahead forecast vs actual load in GW (EIA-930) — system-wide context, identical across nodes

Load Options

• Consecutive: the last N calendar days
• Weekdays: the last N Mon-Fri days, weekends skipped
• Same Day: the last N of the end date's weekday (7 Fridays, 43 Fridays, …) — so N days spans roughly N weeks, and a node commissioned recently will not have that much history

When Fewer Days Come Back Than You Asked For

Dates the node has no data for are dropped, and the Days card then reads loaded / requested with an amber note saying why — the node's own first and last market date, how many requested dates fall outside it, and any gaps inside it. It is a fact about the node's history, not a cap on the selector.

Summary Stats

Period averages are calculated across all loaded days. Positive spread means DA > RT (favorable for INC bids).
