Observed Five-Minute Generation by Fuel

CAISO Today's Outlook five-minute observed generation by fuel, including signed battery output and net imports.

One row per: event_time; 5-minute cadence
Evidence: Observed market data; Published observations from the named source
Time basis: Point-in-time records; UTC · event_time

Overview

Battery charging is negative output and is used to compare system demand with forecasts on the same basis. The time-only current file must be anchored to its actual Pacific source day; captures preceding their claimed observation time are ineligible for serving.

Query contract: Preserve one canonical row per (event_time) before aggregating.
Analysis rules: Group only after preserving the declared grain: event_time.

Dataset	Description
Battery Storage Net OutputCAISO · 5-minute	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.
Daily HTML report and corrected publicationCAISO · day publication	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.
EDAM Wind and Solar Forecast by Balancing AreaCAISO · hourly delivery; half-hourly collection	CAISO OASIS EDAM wind and solar generation forecasts by balancing-authority group, with the delivery hour and publication vintage retained separately. Forecasts for participating areas are not CAISO system generation.
Renewable Generation ForecastCAISO · 5-minute RTD and hourly DAM	CAISO wind and solar forecasts by trading hub and market run. event_time is delivery time and source_time is publication time. Historical forecast-error analysis must use the last source_time at or before delivery; using a later revision introduces hindsight.
