1. What “monthly price” means here

The electricity price series reproduces AVGRRP from AEMO’s official monthly average price CSVs. It is a published, time-weighted regional average in nominal AUD/MWh. The five series are NSW1, QLD1, VIC1, SA1 and TAS1. NSW1 includes the ACT; WA, NT and the former Snowy region are outside this dataset.

Coverage starts in July 2005. Only complete calendar months are displayed. Dates follow NEM market time, fixed AEST (UTC+10), rather than daylight-saving local time. AEMO’s monthly CSV date is the month-end date; we convert it to YYYY-MM. Source values are retained numerically and shown to two decimal places.

We do not independently reconstruct every monthly average or calculate a national aggregate. This is not a demand-weighted average, retail tariff, settlement invoice, generator capture price or PPA transaction index. Peak-hour price (PEAKRRP) is not used. Negative prices are retained without clipping.

2. Calculations and historical intervals

The chart’s first-to-last percentage is (last / first − 1) × 100, shown only when the first price is positive. Otherwise the page shows an absolute AUD/MWh change. A single month has no comparison. Month-to-month percentage comparisons follow the same rule.

NEM settlement moved from 30-minute to five-minute intervals on 1 October 2021. Our source is AEMO’s published monthly series across that change. Raw interval spot checks use the applicable interval length, fixed AEST and interval-ending timestamps: after the start of the month, through midnight at the start of the next month. Only TRADE rows are included; no forecast rows, interpolation or missing-interval replacement.

3. Updating and preserving verified data

This site publishes reviewed historical datasets. Data is updated through reviewed releases, not on each visit. Automatic source checks and alerts are not currently enabled.

Data coverage, recorded verification dates and publication dates describe the retained snapshot; they do not imply a new source check. Changes to published data require publishing a new verified snapshot.

4. MLF directory and technology labels

590 unique DUIDs are retained from all generation and bidirectional-unit tables in AEMO’s FY 2026–27 MLF report, version 3 (22 July 2026). Separate load TNI tables are excluded. A DUID identifies a dispatch unit or aggregate, not necessarily one physical site, and appearance in this report does not confirm current operation. NSW1 includes ACT.

FY 2025–26 values are the report’s comparison column, not a reconstruction of factors applied throughout that earlier year. The published revisions effective 1 July 2026 are used for Corowa and Wandoan South solar farms. Shared DUID station names are retained as aliases. Bidirectional import and export factors, and Basslink directional entries, remain separate.

Technology is a conservative editorial grouping using explicit report names and matched AEMO or operator asset lists; it is not a live registration classification. Each row links its classification evidence. Storage includes batteries, hybrid bidirectional units and identified pumped hydro. Auxiliary loads and interconnectors are separate; unconfirmed technologies, including some thermal and bioenergy facilities, remain Other / Unclassified. Fuel filters may therefore omit unconfirmed units of that technology.

Names, DUIDs, connection point IDs, TNI codes, voltage, report page and version are retained. Two annual values for the selected direction are shown as separate bars, with no implied interpolation. MLFs can be revised; check the applicable official data for settlement use. This fixed MLF snapshot is not changed by the price updater.

5. Quality checks and traceability

Every month must contain exactly one value for each of the five included regions. Missing months, duplicates, unexpected regions, invalid dates and non-numeric values block publication. Source CSVs and SHA-256 checksums are retained for audit. Checksums identify the retrieved bytes; they do not certify the underlying data’s accuracy.

Independent checks compare selected regional monthly averages with their full interval RRP files, including periods before and after the five-minute change. These are spot checks, not validation of every raw interval in the historical series. Errors remain possible; consult the linked official source when relying on a result.

6. Reuse, independence and privacy

Underlying data © Australian Energy Market Operator (AEMO). AEMO’s general copyright permission permits use of AEMO-created public material with accurate attribution; confidential material and copyright owned by others are excluded. Source-specific restrictions still take priority. We reviewed the dashboard notice and selected report notices for these datasets; this is a source review, not legal certification.

Downloads are free and do not require registration. We add no blanket “non-commercial only” restriction to AEMO material and make no promise beyond the source permissions. Future commercial services would need to respect those permissions.

月度现货电价的口径

电价直接使用 AEMO 官方月度 CSV 的 AVGRRP 字段，按 NSW1、QLD1、VIC1、SA1、TAS1 分别展示，从 2005 年 7 月开始。金额为名义澳元/兆瓦时，保留源值，显示两位小数。NSW1 包括 ACT；不包括西澳、北领地或历史 Snowy 区域。

这是时间加权的区域月均现货电价，不是需求加权电价、零售电费、结算账单、发电单元捕获价或 PPA 成交价。不使用 PEAKRRP，不截掉负电价，也不编造全国均价。只发布完整月份，使用 NEM 固定 AEST（UTC+10）口径。

计算与验证

首末月变化按（末月 ÷ 首月 − 1）× 100 计算，仅在首月价格大于零时展示百分比，否则显示绝对金额变化。2021 年 10 月 1 日结算从 30 分钟切换为 5 分钟；网站沿用官方月度系列。抽查原始数据时核对对应间隔、完整时间轴，只纳入 TRADE，不补缺、不混入预测。

每个月必须有五个地区各一条记录。缺月、重复、格式变化或无效值会阻止更新。下载包含源链接、SHA-256、检查时间、方法版本和归属信息。哈希用于追溯文件，不代表准确性认证。抽查不等于对所有历史区间逐条复算。

自动检查的实际范围

网站发布经审核的历史数据，通过审核后发布新版本更新，不在访问时检查来源。目前未开启自动更新或告警。页面显示的核验时间属于保留快照，不表示刚刚检查了来源。

MLF 覆盖与分类

MLF 覆盖 2026–27 财年报告第 3 版（2026 年 7 月 22 日）发电及双向单元表中的 590 个唯一 DUID，不包括另列的负荷 TNI 表。DUID 不等于物理电站，也不表示当前正在运行。2025–26 值是报告的对比列，不是完整历史实际适用因子。双向储能的 Import / Export 分别保留；共享 DUID 的电站名保留为别名。采用 Corowa 和 Wandoan South 自 2026 年 7 月 1 日生效的修订值。

英文技术分类来自报告明确名称，以及 AEMO 或运营商资料的匹配，是保守的编辑分类，不是实时注册清单。Storage 包括电池、混合双向单元和已识别的抽水蓄能；厂用负荷、互联线单列，无法确认类型的单元归入 Other / Unclassified，因而技术筛选可能遗漏尚未分类的同类单元。详情与 CSV 保留分类依据。MLF 是因子，不是电价，不能独立说明项目盈利；电价更新不会自动更新 MLF。

许可、独立性与隐私
