Plants and generation
US power plant inventoryOperating US power plants and batteries from the August 2026 EIA-860M and the final 2025 EIA-860, with capacity, technology and operating dates.Monthly power plant generationMonthly net generation, battery charging and discharge, and fuel heat input for US power plants from EIA-923, January 2000 to July 2026.Power plant emissionsAnnual CO₂, SO₂ and NOx mass for EPA-monitored power plant units, 1995 to 2025, from EPA Clean Air Markets, linked to EIA plants.Ownership and offtake contractsOwners, parent companies, PPAs and contract buyers for US power plants, from FERC MBR and EQR data, EIA-860 and reviewed public filings.ERCOT resource dataHourly settlement-metered net energy for reviewed ERCOT resources, March 2014 to July 2026, with battery telemetry and resource registries.
Market prices
Day-ahead power pricesDay-ahead prices for every hub, zone and node in the seven US ISO and RTO markets, with congestion and loss components where published.Real-time power pricesFive-minute real-time prices at every hub, and every node with hourly means, in the seven US ISO and RTO markets.Ancillary service pricesDay-ahead and real-time prices and cleared MW for regulation, spinning, non-spinning and other reserves in all seven US ISO and RTO markets.Binding transmission constraintsDay-ahead and real-time shadow prices for binding transmission constraints in the seven US ISO and RTO markets, with a registry of every constraint seen.Capacity auction resultsCapacity auction clearing prices and cleared MW by zone for PJM, MISO, NYISO and ISO-NE, in native units and $/MW-day, from the 2006 delivery year.
Grid operations
ISO load, fuel mix and storageEach ISO’s own system load, generation by fuel and storage output, every 5 minutes, for CAISO, ERCOT, ISO-NE, MISO, NYISO, PJM and SPP.EIA-930 hourly load and fuel mixHourly demand, demand forecast, interchange and generation by fuel for every US balancing authority from EIA-930, July 2015 to the latest hour.ISO load, wind and solar forecastsEvery published ISO load, wind and solar forecast vintage, stored by publish time, with the forecast in force at the day-ahead deadline.Generation outagesGeneration outage reports from the seven US ISOs: unit events in some markets, outage MW by type in others, with every report kept as a vintage.Interconnection queuesEvery generation request in the seven US ISO interconnection queues, as daily snapshots with a per-project change log, plus LBNL Queued Up history.Operator-reported curtailmentWind and solar curtailment as CAISO and SPP publish it: CAISO monthly totals for 2015 to 2025 and SPP annual mean curtailed MW for 2024 and 2025.
Network, water and siting
US substationsAbout 80,000 US substations compiled from OpenStreetMap, ISO, state and federal sources, with a crosswalk to pricing nodes, plants and queue points.Transmission and local power lines687,028 mapped power line and cable segments in the 50 states and DC, from an OpenStreetMap snapshot of September 25, 2026, with reported voltage.Plant cooling water and watershed stressAnnual cooling-water withdrawal and consumption for US thermal plants from EIA, 2014 to 2024, joined to USGS surface water stress by watershed.Plant and airport weatherHourly point weather at every US wind and solar plant from 2010, and NOAA GHCNh hourly weather at about 2,300 US airports from 2010.
Model outputs
Expected generation and physical potentialInfraMap models of what each US plant could have produced from its weather and equipment, and of its expected monthly output, from January 2010.Modeled curtailmentExperimental InfraMap estimate of the energy US wind and solar plants likely withheld, from physical potential and the real-time price at each node.Modeled battery revenueInfraMap model of what a 1 MW battery could have earned from energy arbitrage at each pricing node, for 1, 2 and 4 hour durations, by month.Estimated shift factors and congestionInfraMap statistical fit of each pricing node’s congestion price against binding constraint shadow prices, used to explain basis.
