Overview

Prefer the typed live_load, live_capacity, and live_grid_metrics tables for calculations.

Query contract

Select one latest watcher snapshot before reading publisher-titled raw values.

Analysis rules

Group only after preserving the declared grain: raw_id, raw_datetime_est, raw_value.

Interpretation

raw_value is a display string. Use the typed live_load, live_capacity, or live_grid_metrics dataset for arithmetic.

Access

Query from your own tools

Use the guarded HTTP endpoint directly, or connect an MCP client and load the dataset contract with describe_data before calling query_data.

Dataset	Description
MISO Interconnection QueueMISO · daily snapshot	MISO's public generator interconnection queue, including project identity, developer, county and state, proposed point of interconnection, transmission owner, technology, requested capacity, status, and negotiated or actual completion dates where published. Each posting is a snapshot: current totals must use one latest snapshot, and requested queue MW is not operating capacity, available transmission headroom, completed study work, or evidence that a project will be built.
MISO Price LocationsMISO · slow-moving dimension, refreshed every 6 hours	Every MISO location that carries a price, as three columns: location_id, name, and kind. 325 rows — generator (274), interface (22), zone (21), hub (8). This is the dimension the MISO price, and where applicable constraint, tables join to, and it is the one place a location's type is decided: resolve "which hubs exist", "is this a zone or a node", or "give me the readable name for this id" here rather than inferring a type from a name prefix. For MISO, name equals location_id (the node name, e.g. ALTE.1ROCKGEN). MISO publishes no pricing-node registry, so this dimension is assembled from grid.entities rather than from a MISO feed. It covers MISO's hub and zone roll-up, which is coarser than a full nodal set. The same three columns exist for every market, so the equivalent question in another ISO is the same query against that ISO's table.
Baja California (CENACE) Price LocationsBCA · slow-moving dimension, refreshed every 6 hours	Every Baja California (CENACE) location that carries a price, as three columns: location_id, name, and kind. 4 rows — zone (4). This is the dimension the Baja California (CENACE) price, and where applicable constraint, tables join to, and it is the one place a location's type is decided: resolve "which hubs exist", "is this a zone or a node", or "give me the readable name for this id" here rather than inferring a type from a name prefix. For Baja California, location_id is CENACE's load zone (TIJUANA, MEXICALI, ENSENADA, SANLUIS) and joins cenace.zonal_prices.load_zone; name is the city it is named for. CENACE prices Baja California by load zone only; there are no nodes or hubs in this dimension. The same three columns exist for every market, so the equivalent question in another ISO is the same query against that ISO's table.
