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
• CC La: MISO system committed capacity in GW (CsatSupplyDemand 15-minute actuals averaged per hour) — the "Committed Capacity" line of MISO's Supply and Demand chart, system-wide and identical across nodes. Archive starts 2026-09-08; older dates and slots MISO never backfilled show a dash

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.

DA CC Filter

Type a number in the DA CC filter box (say 30, with the comparator on >) and every pooled statistic on the page is recomputed over the hours whose Day-Ahead congestion component passes it: Period DA, Period RT, Period Spread, INC Win% and INC σ, plus a CC Hrs / CC Spread / CC Win% group on each day box and a CC row under each table's AVG row. Cards that have narrowed wear the rule; the line under them gives the counts.

• Rows that fail the rule stay in the table, dimmed — which hours did not qualify is half of what a conditional win rate means. Nothing is refetched; the rule only decides which of the loaded hours a number describes.
• An hour with no DA CC published is neither a match nor a miss. It is counted separately and named in the notice, never folded into the hours that failed.
• The AVG row still means the whole day. A filter adds a number here; it never redefines one.
• The rule sticks across reloads and rides the URL as ?cc=&cc_op=, so a finding is shareable. Clear the box (or press ×) to go back to every hour.
• Frame: a delivery day's own DA CC is published when the day-ahead market clears — after that day's 10:30 ET bid cutoff. Conditioning on it describes what happened at the node; it is not a signal you could have bid into. The CSV export is unfiltered and carries the DA CC column.

Summary Stats

Period averages are pooled over every loaded hour. Each leg is averaged over the hours that actually published it — a day whose RT has not printed yet contributes to Period DA and not to Period RT, rather than dragging the RT average toward zero — and each card's tooltip carries its own hour count. Positive spread means DA > RT (favorable for INC bids).

• INC Win%: percent of paired hours (DA and RT both published) where DA > RT — an INC placed there wins — with the winning-hour count in parentheses; win/lose/tie counts sit in the card tooltip
• INC σ: sample standard deviation of the DA − RT spread ($/MWh) across those same paired hours — the volatility behind Period Spread; needs at least 2 paired hours
