About

NEMWeb is where the Australian Energy Market Operator publishes the files behind the National Electricity Market. The Current directory at nemweb.com.au/Reports/Current/ holds a folder per report: five-minute dispatch, pre-dispatch, trading prices, operational demand, rooftop PV, PASA adequacy, settlements, bids, network outages and market notices. Each file is a zip holding one CSV in AEMO's MMS layout, with I rows naming the columns and D rows carrying the data; the Electricity Data Model Report documents every table. Older files move to the Archive, which keeps up to thirteen months.

An operator polls the dispatch price for your region and proposes when to shed, shift or discharge. You approve the plan and keep the receipt.

This is a reference listing. It documents what Fibric would read from AEMO NEMWeb and what it could propose, based on the publisher's published interfaces. Fibric builds it under a managed deployment when you request it; selecting it here installs nothing.

Inputs

  • DispatchIS_Reports: PUBLIC_DISPATCHIS zips every five minutes with DISPATCH PRICE, REGIONSUM, INTERCONNECTORRES, CONSTRAINT and CASE_SOLUTION tables
  • Predispatch_Reports and P5_Reports: 30-minute pre-dispatch and 5-minute pre-dispatch summaries
  • Public_Prices daily zips and the TradingIS_Reports folder: trading and dispatch price files
  • Operational_Demand and ROOFTOP_PV: actual and forecast operational demand, rooftop PV measurement and forecast, by area
  • Short_Term_PASA_Reports, PDPASA, Medium_Term_PASA_Reports and the 7 Day Outlook folders: supply adequacy
  • Market_Notice: one NEMITWEB1_MKTNOTICE file per notice
  • Network, HighImpactOutages, Marginal_Loss_Factors and Dispatch_SCADA folders

Proposed actions

Read-only. This feed informs operators; it changes nothing.

Proposed actions are target capabilities. Every action runs propose-first and needs a validated deployment and the appropriate permissions.

What you can build

  • Shed load on a five-minute price spike

    Poll DispatchIS_Reports and read the DISPATCH PRICE row for your region. When the price crosses your threshold, the operator proposes which loads to shed and for how long, with the interval and price on the receipt.

    With Price Shift, Peak Demand

  • Plan tomorrow's battery cycle from pre-dispatch

    Read the 30-minute pre-dispatch prices from Predispatch_Reports for your region. The operator proposes charge and discharge windows against your load forecast and shows the pre-dispatch run it used.

    With Battery Dispatch

  • Cap solar export when the regional price falls

    Watch the dispatch price for your region. When it drops below your export threshold, the operator proposes an active-power cap on the inverters for the coming intervals, for your approval.

    With Export Limit

Requirements

  • A poller that lists a Current folder and downloads new PUBLIC_*.zip files by name and timestamp
  • The Electricity Data Model Report under MMSDataModelReport to map each table's I-row columns
  • A client that unzips and parses CSV; nemweb.com.au serves files and HTML listings only
  • Attribution of AEMO as author of AEMO Material under its copyright permissions
Authentication
No key. nemweb.com.au serves directory listings and files over plain HTTPS; no sign-up is documented for the public reports.

Limits

  • Files are zipped CSV in the MMS C/I/D layout, not JSON; every table must be parsed from its own I row
  • Current folders hold recent files only; the Archive keeps up to thirteen months and older data sits in the Data Model Archive
  • Directory listings are HTML; there is no query API, filter or subscription on nemweb.com.au
  • Predispatch_Reports files carry a _LEGACY suffix and the portal labels a Legacy predispatch report; check the Data Model Report before parsing

Questions and answers

Do I need to register to download NEMWeb files?
No. The Current and Archive directories answer plain HTTPS requests and list files as HTML. Public files carry PUBLIC in the name. AEMO's market portals, which need participant access, are separate and not part of this listing.
What is inside a DISPATCHIS zip?
One CSV in AEMO's MMS format. A C row carries report metadata, each I row names a table and its columns, and D rows carry the data. The file fetched held DISPATCH CASE_SOLUTION, CONSTRAINT, INTERCONNECTION, INTERCONNECTORRES, LOCAL_PRICE, PRICE and REGIONSUM. The Electricity Data Model Report documents each column.
How much history does NEMWeb keep?
The Current directory holds recent files. AEMO's market data page says older files are automatically moved into the archive and up to thirteen months of data is stored; the Archive folder for DispatchIS_Reports held one zip per day. Older data is stored in the Data Model Archive.
