ISO-NEAlertsATG Data·ISONE·ISO-NE's published Alerts source feed. This catalog page exposes the physical schema, coverage, and latest source rows without inventing a normalized grain for publisher-shaped snapshot fields. Use the documented key and event time when comparing revisions or vintages.01970
Customer Outages by CountyATG Data·US reference·Live county-level customer outage snapshots from ORNL/DOE's ODIN public county map API. Ask the Grid queries the nationwide grid='us' archive and derives each live product map from its exact state-FIPS scope, so every supported grid uses the same accumulated history. Each row is an active county outage at that snapshot with county FIPS, state FIPS, affected meters, contributing utility rows, and the ODIN county polygon. Missing county rows at a snapshot mean zero or cleared public ODIN outage, not stale carry-forward. This is distribution/customer outage data, not ISO generation or resource outage data.1.6M2026
ERCOTERCOT Outage CapacityATG Data·ERCOT·How much ERCOT generation capacity is expected to be unavailable, one row per target hour and region. 268,745 rows, 2017-01 out to roughly eight days ahead. Regions are system, north, south, west and houston. ERCOT publishes this as a rolling forward view with an hourly vintage for every target hour — 15.17M raw rows across 83,875 vintages. This table collapses that to the latest published view of each target hour, which is what almost every question about expected outages actually wants, and removes the vintage-selection step where those questions usually go wrong. ERCOT reported this system-wide until 2021 and regionally afterwards; system rows are ERCOT's own total where it published one and the sum of the four regions after. No hour carries both. The forced-versus-planned split and the separate IRR and new-equipment categories are NOT here — they remain in ercot.hourly_resource_outage_capacity and ercot.reported_outages.269.8K2017
NYISOGeneration Maintenance ForecastATG Data·NYISO·NYISO rolling forecast of total generator maintenance outage MW by future date. This is a forward outage/availability context feed and currently has no full historical archive writer.1.4K2026
PJMGeneration Outages by TypeATG Data·PJM·PJM's daily generator-outage outlook by report date, target forecast date, and region. Each row separates total, planned, maintenance, and forced outage capacity in MW for PJM RTO, Western, or Mid Atlantic - Dominion. This is generation availability evidence from PJM Data Miner 2, not distribution-customer outage data. Source: PJM Data Miner 2.87.0K2015
NYISOGenerator & Transmission Outage ScheduleATG Data·NYISO·NYISO scheduled generator and transmission outage records by PTID and equipment name, including scheduled out and scheduled in timestamps.827.6K2001
ERCOTHourly Resource Outage CapacityATG Data·ERCOT·ERCOT's Hourly Resource Outage Capacity report — the amount of generation capacity out of service across the Texas grid, projected hour by hour over a rolling seven-day horizon. Each posting from the Outage Scheduler breaks the outaged megawatts out by weather zone (South, North, West, Houston) and by category: Total Resource (a proxy for thermal outages), Total IRR (intermittent wind and solar), and Total New Equipment Resource (units still in commissioning). It is bitemporal — every row carries both the projected delivery hour (event_time) and the publishing vintage (source_time), and because ERCOT revises the projection every hour, successive vintages accumulate as distinct rows rather than overwriting. This is the core dataset for seeing how much capacity is unavailable at any moment, how outage expectations shift as an operating hour approaches, and how planned and forced outages concentrate by region — a direct input to scarcity, reserve adequacy, and reliability-unit-commitment analysis. The official source is ERCOT report NP3-233-CD, Hourly Resource Outage Capacity.15.3M2017
MISOLive Generation-Outage OutlookATG Data·MISO·MISO's rolling eleven-day generation-outage outlook in MW, separated into planned, unplanned, forced, and derated categories. Categories are publisher-defined capacity totals, not counts of units or causes.4952026
NYISOOperator MessagesATG Data·NYISO·NYISO operational announcements and dispatcher-issued messages, including interface scheduling changes, manual reductions, and market notices.361.9K2000
NYISOOperator-Initiated CommitmentsATG Data·NYISO·NYISO out-of-merit operator-initiated commitment records by resource PTID and event start time, including requester, commitment type, load zone, reason, ARR, UOL, and committed MW fields.63.0K2019
ERCOTPlanned Resource Outage Capacity LimitsATG Data·ERCOT·ERCOT's operating-day Resource Planned Outage Limit (RPOL) and the aggregate planned-outage megawatts already approved or received for that day. The report separates non-IRR/non-PUN generation, Energy Storage Resources (ESR), and Intermittent Renewable Resources (IRR), and publishes successive vintages from seven days through 60 months ahead. It is grid-level scheduling evidence: it does not identify the resources behind the approved or received totals. The official source is NP3-161-CD, Available Resource Planned Outage Capacity Margin 7 Day Plus.234.8K2026
ISO-NEPower System ConditionsATG Data·ISONE·ISO-NE's published system-condition status and operator action description by reported area. Treat the text as an operator status, not as a numeric reliability probability.9.6K2026
ISO-NEPrice Resp EventATG Data·ISONE·ISO-NE's published Price Resp Event source feed. This catalog page exposes the physical schema, coverage, and latest source rows without inventing a normalized grain for publisher-shaped snapshot fields. Use the documented key and event time when comparing revisions or vintages.01970
NYISOReal-Time Grid EventsATG Data·NYISO·NYISO real-time grid event messages, including operating reserve activations, state changes, and advisories. Use it to contextualize unusual price, reserve, or reliability conditions.34.4K2001
NYISOReal-Time Line OutagesATG Data·NYISO·NYISO real-time transmission line outage records by line PTID and equipment name, including the outage timestamp for currently de-energized or outaged lines.332.6M2001
MISOReal-Time Outage DeltaATG Data·MISO·System-wide forward and real-time MISO outage capacity in MW and their difference. The aggregate does not identify individual generators, outage causes, or whether an outage was planned or forced.57.0K2026
MISORegional Outage ForecastATG Data·MISO·Hourly forecast generation capacity on outage in MW by MISO sub-region. It is an aggregate capacity outlook, not a unit-level outage list or an observed cause record.94.2K2026
ERCOTReported Generation OutagesATG Data·ERCOT·The ERCOT Generation Outages dashboard feed, recorded as system snapshots. It reports total, planned, and forced or unplanned generation-capability reductions, with dispatchable and renewable breakdowns. These are aggregate MW values submitted by Market Participants and can include full outages and partial reductions; they are not per-resource outage identities. The dashboard covers the current day and previous six days.32.4K2026
ISO-NESchedule2 VAR StatusATG Data·ISONE·ISO-NE's published Schedule2 VAR Status source feed. This catalog page exposes the physical schema, coverage, and latest source rows without inventing a normalized grain for publisher-shaped snapshot fields. Use the documented key and event time when comparing revisions or vintages.9252020
NYISOScheduled Line OutagesATG Data·NYISO·NYISO scheduled transmission line outages by line PTID and equipment name, including scheduled out and scheduled in timestamps.283.9M2001
