DatasetRows
AESO Solar Actual (10-minute)ATG Data·US reference·Alberta's total solar output every ten minutes, with AESO's most-likely, minimum and maximum forecast for the same interval and installed solar capacity.——
AESO Solar Forecast (12-hour)ATG Data·US reference·AESO's 12-hour solar forecast in ten-minute steps, with its minimum, most-likely and maximum envelope, every retrieval kept.——
AESO Solar Forecast (7-day)ATG Data·US reference·AESO's seven-day hourly solar forecast, every retrieval kept.——
AESO Unit Output and Capability (polled)ATG Data·US reference·Every reporting Alberta generating asset at each poll: AESO asset code, fuel and sub-fuel, maximum capability, net generation and dispatched contingency reserve. Summed by fuel_type at one poll it reproduces the system total.——
AESO Wind Actual (10-minute)ATG Data·US reference·Alberta's total wind output every ten minutes, with AESO's most-likely, minimum and maximum forecast for the same interval and installed wind capacity.——
AESO Wind Forecast (12-hour)ATG Data·US reference·AESO's 12-hour wind forecast in ten-minute steps, with its minimum, most-likely and maximum envelope, every retrieval kept.——
AESO Wind Forecast (7-day)ATG Data·US reference·AESO's seven-day hourly wind forecast, every retrieval kept.——
SPPAll hourly reserve-zone forecast vintagesATG Data·SPP·SPP's All hourly reserve-zone forecast vintages. Each row preserves a publisher record, workbook row, or report document with its source member and row index. Source timestamps, units, geographic scope, and revision qualifiers are retained in record_json; event_time is collection time; completed_at is when the entire document became available.311.8K2026
Balancing Authority Generation by FuelATG Data·US reference·EIA-930 hourly net generation by energy source for every reporting balancing authority, one wide row per (ba, hour). 5.2M rows, 83 BAs, 2019-01 to now. Each EIA source code is its own additive column: coal, gas, oil, nuclear, hydro, pumped storage, wind, wind with storage, solar, solar with storage, battery, other and unknown storage, geothermal, other and unknown.5.2M2019
CAISOBattery Storage Net OutputATG Data·CAISO·Observed five-minute net output from standalone and hybrid battery storage across the CAISO footprint. The total supply_mw field is positive when batteries are discharging into the grid and negative when they are charging from the grid; standalone_batteries_mw and hybrid_batteries_mw are components of that total, not additional generation to add on top. This is the live operating series published in CAISO Today's Outlook, not nameplate capacity or state of charge.389.5K2023
NYISOBehind-the-Meter Solar ActualATG Data·NYISO·NYISO estimated behind-the-meter solar output by load zone and a published SYSTEM total at hourly resolution. NYISO releases each completed operating day on the following day, so this is a published completed-day estimate rather than a live meter reading.613.5K2020
NYISOBehind-the-Meter Solar ForecastATG Data·NYISO·NYISO day-ahead behind-the-meter solar forecast by load zone and a published SYSTEM total at hourly resolution. source_time preserves the file's real publication timestamp; compare a delivery hour only with the matching completed-day estimate, never with a sum that also includes SYSTEM.681.7K2020
NYISOBehind-the-Meter Solar Installed CapacityATG Data·NYISO·NYISO estimated behind-the-meter solar installed capacity by load zone. This tracks distributed PV nameplate growth over time.15.4K2023
BPA Balancing Area Load and GenerationATG Data·US reference·BPA balancing authority load, wind, solar, hydro, thermal, nuclear and net interchange every five minutes since 2007, as BPA publishes them, with the live seven-day feed beside the yearly workbooks.2.1M2007
CENACE Settled Generation by TechnologyATG Data·US reference·Hourly settled generation (MWh) for Mexico's National Electric System by CENACE technology: wind (eolica), solar (fotovoltaica), biomass, coal, combined cycle, internal combustion, geothermal, hydro, nuclear, conventional thermal and gas turbine.——
CENACE Wind and Solar ForecastsATG Data·US reference·CENACE's hourly wind (eolica) and solar (fotovoltaica) generation forecasts for the day-ahead market, by system, every publication kept.——
Columbia River Dam OperationsATG Data·US reference·Hourly and daily operations of Columbia and Snake River hydro projects, including Bonneville Dam (BON), Grand Coulee, Chief Joseph, McNary, John Day, The Dalles, Ice Harbor and Lower Granite, from the Corps' Dataquery: forebay and tailwater elevation, outflow, spill, turbine flow, generation (MW), inflow and storage, one row per CWMS series and time.85.0M1960
SPPCompleted-year curtailment archiveATG Data·SPP·SPP's Completed-year curtailment archive. Each row preserves a publisher record, workbook row, or report document with its source member and row index. Source timestamps, units, geographic scope, and revision qualifiers are retained in record_json; event_time is collection time; completed_at is when the entire document became available.0—
CAISODaily HTML report and corrected publicationATG Data·CAISO·CAISO's Daily HTML report and corrected publication. Each row preserves a publisher record, workbook row, or report document with its source member and row index. Source timestamps, units, geographic scope, and revision qualifiers are retained in record_json; event_time is collection time; completed_at is when the entire document became available.82026
SPPDaily VER curtailments, preserving BAAATG Data·SPP·SPP's Daily VER curtailments, preserving BAA. Each row preserves a publisher record, workbook row, or report document with its source member and row index. Source timestamps, units, geographic scope, and revision qualifiers are retained in record_json; event_time is collection time; completed_at is when the entire document became available.5.2K2026
MISODay-Ahead Cleared GenerationATG Data·MISO·Hourly MISO day-ahead cleared supply by region and physical or virtual segment. Virtual supply is a financial market position and must not be summed into physical generation output.185.6K2021
NYISODay-Ahead Implied Marginal Emission RateATG Data·NYISO·NYISO day-ahead implied marginal emission rate by zone, including CO2 and NOx rates derived from day-ahead LBMP, VOM, and implied heat rate.183.3K2024
MISODay-Ahead Offered GenerationATG Data·MISO·Hourly day-ahead generation offers by MISO region and ECOMIN or ECOMAX bound, separated into must-run, economic, and emergency MW. Offered capability is not the same as cleared or physically generated energy.291.5K2021
Dispersed GenerationATG Data·US reference·EIA-861 dispersed generation capacity by technology and utility, 2012 to 2015. Dispersed sheets of the discontinued distributed_generation file. event_time is 1 January of the report year. release is final or early_release: EIA posts an early release of a year in August and replaces it with the final file in the autumn, and the mirror keeps the newest row per key. A key cell EIA leaves blank is '' or 0, and duplicate_index numbers rows that still share a key, in workbook order.9272012
Distributed GenerationATG Data·US reference·EIA-861 distributed generation capacity by technology and utility, 2012 to 2015. Distributed sheets of the discontinued distributed_generation file, succeeded by net_metering and non_net_metering_distributed. event_time is 1 January of the report year. release is final or early_release: EIA posts an early release of a year in August and replaces it with the final file in the autumn, and the mirror keeps the newest row per key. A key cell EIA leaves blank is '' or 0, and duplicate_index numbers rows that still share a key, in workbook order.1.3K2012

About generation data

These datasets connect current grid operations with the generating fleet behind them. Use fuel-mix and plant-level output to track realized generation, renewable forecasts to compare expected and actual wind or solar production, and federal generator inventories to research capacity, technology, and operating status.
