🌀 NEM Wind Fleet — Value Factor & Profile Dashboard

Value factor — the farm's average selling price compared with the average price in its region over the same period (industry shorthand: generation-weighted price ÷ time-weighted price, VWAP ÷ TWAP). Above 100% means the farm's energy is worth more than the average MWh. Solar sliding below 100% is the well-known midday "cannibalisation" effect; wind that blows into the evening peak can exceed 100%.

Capacity factor — average output as a share of maximum (nameplate) capacity. Capacities marked ~ are estimated from the unit's own observed output (99.7th percentile) because it isn't in the hand-checked registry — treat those as indicative.

Output at negative prices — the share of the farm's generation produced while its regional spot price was below $0. Revenue counts wholesale energy sales only: no contracts (PPAs), green certificates (LGCs), or system-services (FCAS) income.

Periods. Daily is one calendar day of dispatch (intervals attributed to the day they were generated in, not the timestamp they close on). Financial year is the Australian July–June year, so FY2024-25 runs July 2024 to June 2025; a year the data doesn't fully cover is labelled with the months it actually has, because a part-year sitting beside a full one in the picker is an easy way to conclude a fleet halved its output. Quarters and financial years are aggregated from the monthly figures with the weighting each metric needs — energy-weighted price, hours-weighted capacity factor — never by averaging monthly percentages.

Daily value factors need care. Over a month a region's average price is comfortably positive and VWAP ÷ TWAP is stable. Over a single day the regional average can sit near or below zero, and the ratio then explodes or flips sign — a farm earning −$4 against a −$2 average would score 200%. Days whose regional average falls below $5/MWh are shown with no value factor rather than an uninterpretable one; the price earned and the revenue are still there, and on those days they are the honest numbers. Expect a much wider spread day to day than month to month either way: one evening spike can carry a farm's whole day.

Fine print: the regional average price is the full-month average even when a farm ran for only part of the month — a farm commissioned mid-month is compared against the whole month's market. Revenue covers intervals where both output and price data are present. Source: AEMO NEMweb dispatch SCADA (as-generated MW, not settlement metering) and dispatch prices.
