Balancing Authority Day-Ahead Demand Forecast

EIA-930 day-ahead demand forecast for every reporting balancing authority, keyed by ba.

EIALoad data ERCOT market NYISO market CAISO market PJM market MISO market ISO-NE market SPP market

One row per: balancing authority x forecast hour; Hourly cadence
Evidence: Forecast data; Forward-looking values with an explicit issue time
Time basis: Interval-end records; UTC · event_time

Overview

4.5M rows, 71 BAs, 2019-01 through the next day. One forecast per hour, latest submission; join atg.ba_load on (ba, event_time) for forecast error.

Query contract: One row per (ba, event_time) is already the latest EIA submission; read it plainly.
Analysis rules: Filter ba to your scope's code with a direct WHERE; search_data returns the allowed value. One ba per query keeps a region's rows from mixing with another's.Forecast error is atg.ba_load.demand_mw minus forecast_mw for the same (ba, event_time).
Interpretation: event_time is EIA-930's HOUR-ENDING stamp: the row at 18:00 UTC is the 17:00-18:00 hour. To compare with an ISO's interval-start table, match this row at t with the ISO row at t - 1 hour.This is the day-ahead forecast only, the latest submission for each hour; it cannot show how a forecast changed as delivery approached.

Dataset	Description
Balancing Authority Hourly DemandEIA · hourly	Hourly actual demand for every balancing authority that reports to EIA-930, keyed by EIA's BA code in ba. 4.5M rows, 71 BAs, 2019-01 to now. The latest EIA submission for each hour. Every region reads the same columns, so comparing two areas is a filter on ba rather than a second table.
Delivery-Only Company SalesEIA · annual (report year)	EIA-861 delivery companies: revenue, MWh and customers reported by delivery-only companies, by customer class. Delivery_Companies, 2020 on, laid out like sales. customer_class is residential, commercial, industrial, transportation (direct_connected in the distributed generation tables) or EIA's own total, so summing classes without excluding total counts everything twice. 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.
Demand Response ProgramsEIA · annual (report year)	EIA-861 demand response: enrolled customers, energy and peak demand savings and program costs, by utility and customer class. Demand_Response, 2013 on. Savings in MWh and MW, costs in thousand dollars. customer_class is residential, commercial, industrial, transportation (direct_connected in the distributed generation tables) or EIA's own total, so summing classes without excluding total counts everything twice. 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.
Demand-Side ManagementEIA · annual (report year)	EIA-861 demand-side management, 2012 only: energy efficiency and load management effects and costs. The discontinued DSM file, succeeded by demand_response and energy_efficiency in 2013. customer_class is residential, commercial, industrial, transportation (direct_connected in the distributed generation tables) or EIA's own total, so summing classes without excluding total counts everything twice. 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.
