About this dataset — PUBLIC_NEXT_DAY_FPPMW

In the PUBLIC_NEXT_DAY_FPPMW (FPP Daily) data files, these four columns define the exact timing and status of the 4-second SCADA power measurements for batteries and generators.

Column Descriptions

INTERVAL_DATETIME The target timestamp for the 4-second interval. Follows the format YYYY/MM/DD HH:MM:SS and represents the standard grid slot (e.g., :00, :04, :08) the measurement is assigned to.

MEASUREMENT_DATETIME The actual timestamp when the SCADA reading was recorded by AEMO's systems. May differ slightly from INTERVAL_DATETIME due to communication latency or jitter; AEMO snaps each reading to the nearest 4-second slot.

MEASURED_MW The instantaneous power output of the asset in Megawatts (MW) at that specific time. For batteries, positive values denote discharging (generation) and negative values denote charging (load).

MW_QUALITY_FLAG A numeric code indicating data health. Tells you whether MEASURED_MW is a live reading or a substitute inserted because the real data was missing or erroneous (see below).

MW_QUALITY_FLAG Values

The quality flag is critical for ensuring you aren't analysing "frozen" or "bad" data. According to the AEMO FPP Factor Calculation Guide, the digits translate as follows:

0 — Good Data is valid and received directly from the site telemetry.

1 — Substituted / Estimated The raw data was missing. AEMO has "held" the previous known-good value or interpolated a value to fill the gap.

2 — Bad Telemetry is flagged as bad (e.g., communication failure, hardware fault). These points are typically excluded from high-fidelity performance analysis.

3 — Manual Override An AEMO operator has manually adjusted the value to correct for a known system-wide error.

Data Quality

Quality flags are sourced directly from the AEMO FPP dataset. Good (0) = reliable measurement; Suspect (1) = possible communication issue; Bad (2) = sustained failure or substituted value.

4-second SCADA data for the selected BESS and date: ⬇ CSV ⬇ Parquet

Parquet is recommended for Python users — 5–10× smaller than CSV, loads natively with pandas.read_parquet() or polars.read_parquet().

About This App

This tool provides access to two datasets published by the Australian Energy Market Operator (AEMO) via NEMWEB:

4-second SCADA data — from NEMWEB FPPDAILY, published as part of the Frequency Performance Payments (FPP) scheme (commenced 28 February 2025). Currently fetchable from 29 April 2025; earlier daily bundles have been rolled off the AEMO archive.

5-minute dispatch energy data — from NEMWEB Next_Day_Dispatch, with the INITIAL_ENERGY_STORAGE column added on 11 February 2025. Currently fetchable from 1 April 2025; earlier monthly bundles have been rolled off.

Data is fetched live from AEMO on each request — no data is stored on this server. Maximum request window: 1 day per query.
