Hornsdale Power Reserve Unit 1

SA · BESS · HPR1
As of 6 Nov 09:00 NEM time (AEST) · SCADA current
Net SCADA
-28.1 MW
Declared availability (next-day)
75.0 MW
Regional price
$-56.91/MWh

Aligned 5-minute series in NEM time (AEST). Coverage 100% of expected intervals (chart sampled 1 in 6).

Battery SCADA is shown as net MW (+ discharge / − charge). Interval energy uses MW × 5/60 h. State of charge is shown only when Next_Day_Dispatch INITIAL_ENERGY_STORAGE is present — it is not inferred.

Peer comparison

Same technology (BESS) and region (SA). One row per site — DUIDs at the same site are combined and energy-weighted. Period 30 Oct 09:04 – 6 Nov 09:04 NEM time. Coverage 100%. Charge-weighted and discharge-weighted regional reference prices, and the spread between them. Weighted by SCADA energy in each 5-minute interval. Excludes contracts, FCAS, fees, degradation and other costs. Not profit and not a judgement of operator decisions.

Detection defaults for BESS

Availability drop 10.0 MW or 15%; output drop 15.0 MW or 25%; high price from $300.00/MWh while output is below 25% of last-known availability; minimum 10 minutes; cooldown 60 minutes.

AEMO settlement timestamps are period-ending Australian Eastern Standard Time year-round. They do not observe daylight saving. A 14:05 stamp covers 14:00:01–14:05:00 AEST.

Energy and FCAS bid/rebid files (BIDDAYOFFER / BIDPEROFFER) are not ingested. AEMO publishes “Yesterday’s Bids” the next day; this release does not show bid bands, rebids or published reasons.

Binding constraint identities from dispatch are not ingested, so constraint overlays are not shown. State of charge is only stored from Next_Day_Dispatch INITIAL_ENERGY_STORAGE. It is next-day, not live, and is omitted when the field is absent.
