Capacity (AI)

200 MW / 400 MWh

ACEN New England Solar & Energy Storage project page states the project will ultimately include a 200 MW/2 hr battery; 200 MW x 2 h = 400 MWh (acenrenewables.com).

AEMO status Anticipated

Project status Development (AI)

ACEN project page describes the site as an upcoming 200 MW/2 hr battery development (acenrenewables.com, accessed via search result snippet).

Region NSW1

Coordinates -30.35000, 151.63000 (AI)

NSW major projects portal excerpt says the project is approximately 6 km east of Uralla, NSW (majorprojects.planningportal.nsw.gov.au).

Revenue (× MLF)

Estimated $ per interval — energy (RRP) and FCAS (regional FCAS prices), both × MLF.

🔋 State of charge

Stored energy at the start of each 5‑minute interval (AEMO INITIAL_ENERGY_STORAGE). Available up to the latest next‑day dispatch file.

Methodology & assumptions

Dispatch & availability — AEMO Next Day Dispatch UNIT_SOLUTION (5‑minute intervals). Intervention intervals excluded.
Regional price — dispatch_price RRP matched by settlement time and NEM region (from generator registry).
Energy revenue (× MLF) — cleared MW × (5/60 h) × RRP × MLF.
FCAS revenue & volume — cleared FCAS MW from DISPATCHLOAD (raise/lower 6s, 60s, 5min, reg) × (5/60 h) × regional FCAS price × MLF. Volume is total FCAS enablement MWh across services.
State of charge — INITIAL_ENERGY_STORAGE (MWh at interval start) from UNIT_SOLUTION, published for bidirectional/storage units. Next-day data — the SOC line lags real time by up to a day.
Curtailment — estimated economic curtailment when availability exceeds dispatch target: max(0, availability − cleared) × (5/60) MWh.
Not settlement — estimates only. AEMO settlement applies DLF, rebids, constraints, and other factors not modelled here.
