MISO real-time LMP

Preliminary ex-post prices for every MISO commercial pricing node — hubs, load zones, generator nodes and interfaces — with the congestion and loss components, every five minutes. Collected from MISO's public real-time feed and checked against the Data Exchange copy of the same day.

What it measures

Every value, its unit, and what the source means by it.

  • Total LMP$/MWh

    The five-minute preliminary ex-post price at the node.

    lmp_total
  • Congestion$/MWh

    Marginal congestion component — the part that differs between nodes.

    lmp_congestion
  • Losses$/MWh

    Marginal loss component.

    lmp_loss
  • Energy$/MWh

    System marginal energy cost — the same number at every node in an interval. Derived as LMP minus congestion minus losses, MISO's own identity.

    lmp_energy

Columns

Exactly what a request answers with, read from the API rather than written here.

ColumnTypeDescription
interval_start_utcrequiredtimestampStart of the settlement interval, UTC. Always UTC — the ISOs publish in local time with inconsistent DST handling.e.g. 2026-08-14T15:00:00Z
isorequiredstringPublishing ISO.e.g. ERCOT
marketrequiredstringMarket the price cleared in: DAM (day-ahead), RTM (real-time, SCED), or RTPD for CAISO's fifteen-minute market.e.g. RTM
noderequiredstringPricing node or settlement point identifier, as published by the ISO.e.g. HB_HOUSTON
node_typestringNode classification. For ERCOT this is derived from the settlement point naming convention: HUB / LOAD_ZONE / DC_TIE / RESOURCE_NODE. For MISO it is the ISO's own pricing-node type: HUB (every aggregate, the eight trading hubs and the .AZ zones alike) / LOAD_ZONE / RESOURCE_NODE (a generator's node) / INTERFACE. For PJM it is the type on the row: HUB / LOAD_ZONE (a transmission zone) / INTERFACE / EHV / AGGREGATE for the aggregate streams, and RESOURCE_NODE (a generator's bus) / LOAD_BUS / EXTERNAL_BUS for the bus streams. For SPP it is read off SPP's own suffix on the Pnode behind the settlement location: HUB / LOAD_ZONE (a load area) / RESOURCE_NODE / DEMAND_RESPONSE / INTERFACE (a neighbouring operator). For CAISO it is the APnode type in CAISO's own reference: HUB (trading hubs) / LOAD_ZONE (every kind of load aggregation point) / RESOURCE_NODE / DEMAND_RESPONSE (a proxy or reliability demand resource, read off the resource id) / INTERFACE (intertie resources) / EIM_NODE (a Western EIM area's node — CAISO's EIMT, which holds the area's plants and its transfer points alike) / AGGREGATE (generation aggregation points, distributed-resource aggregations, flexible-ramp and imbalance-reserve zones). For NYISO it is LOAD_ZONE (the eleven zones) / INTERFACE (the four external proxy zones, the proxy buses of scheduled lines, and any generator NYISO files in an external zone) / DEMAND_RESPONSE (a demand-response provider) / RESOURCE_NODE (a bus in NYISO's generator reference, DER aggregations included) / LOAD_BUS (a bus NYISO prices beside the generators that no generator is registered to — transformer banks and load buses). For ISO-NE it is the location type ISO-NE publishes, a network node refined by the prefix on its name: HUB (the Internal Hub) / LOAD_ZONE (the eight) / INTERFACE (an external node) / DEMAND_RESPONSE (a demand-response aggregation zone) / HUB_NODE (one of the network nodes the Hub averages) / RESOURCE_NODE (a unit, UN., or a storage plant's asset-related demand, AR.) / LOAD_BUS (a load node, LD.).e.g. APND
lmp_totalrequirednumberTotal locational marginal price, $/MWh.e.g. 41.83
lmp_energynumberEnergy component, $/MWh.e.g. 39.12
lmp_congestionnumberCongestion component, $/MWh. Signed so that total = energy + congestion + loss on every row: NYISO publishes it with the opposite sign, and it is stored negated.e.g. 2.94
lmp_lossnumberLoss component, $/MWh.e.g. -0.23
source_published_at_utctimestampWhen the ISO published this interval, UTC. Lets a buyer distinguish 'we were slow' from 'the ISO was slow'.
collected_at_utcrequiredtimestampWhen Dryos collected this row, UTC. Stamped by the platform, not the collector. Together with interval_start_utc this makes freshness auditable per row instead of only in aggregate.e.g. 2026-08-15T21:22:09Z

Ask an agent

The same stream through the Model Context Protocol, so Claude, ChatGPT, Cursor or any MCP client can query it directly.

shell
claude mcp add --transport http dryos https://api.dryos.ai/mcp

Then ask:

What has Total LMP been at INDIANA.HUB over the last 24 hours, and when did it peak?

Setup for every client is on the MCP server page.

How this stream is checked

  • Pulled straight from MISO Public API · Real-Time Five Minute ExPost — no reseller in between — and compared against that file before it is served.
  • Null means the source did not report it — never zero.
  • A reading lands every 5 min; the interval timestamp is the start of the interval, in UTC.
  • MISO runs on Eastern Standard Time all year and never observes daylight saving. Every timestamp Dryos serves is UTC.
