View data and information from the Australian National Electricity Market (NEM). With NEM Data you have instant access to information published by the Australian Energy Market Operator (AEMO) including wholesale electricity prices, regional demand and supply (including individual power station output), and interconnector flows displayed on an easy-to-use map. Features include: * A dispatch overview map showing regional energy price, demand and supply as well as interconnector flow. Each region can be tapped on to view the previous 24 hours dispatch prices, demand, available generation and interconnector imports, wind and solar generation, and reserve levels. Each interconnector can be tapped on to view the previous 24 hours interconnector flows, and import and export limits. * An hour-ahead price outlook, displaying minimum, median and maximum dispatch prices for each region, sourced from the 5-minute pre-dispatch solution. Each region can be tapped on to view the 5-minute pre-dispatch forecasts of prices, demand, available generation and interconnector imports, wind and solar generation and reserve levels for the next hour. This is updated every 5-minutes and is available in the application as soon as it is published by AEMO. * A day-ahead price outlook, displaying minimum, median and maximum pre-dispatch prices for each region, sourced from the pre-dispatch solution. Each region can be tapped on to view the 30-minute pre-dispatch forecasts of prices, demand, available generation and interconner imports, wind and solar generation and reserve levels for the next trading day. This is updated every 30-minutes and is available in the application as soon as it is published by AEMO. * A week-ahead reserve outlook, displaying a traffic light indication of reserve levels for each region, sourced from the Pre-Dispatch Projected Assessment of System Adequacy (PDPASA) and Short-Term Projected Assessment of System Adequacy (STPASA) processes. Each region can be tapped on to view the forecasts of demand, generation capacity, interconnector import capacity, wind and solar generation capacity, the Lack of Reserve level 1 (LOR1) reserve requirement (or trigger level), the Lack of Reserve level 2 (LOR2) reserve requirement (or trigger level) and reserve levels for the week ahead. * A list of Market Notices issued by AEMO, with the market notice number, heading, type and date of publication visible. Each market notice can be tapped on to view the market notice detailed information. * A demand overview screen showing the regional operational demand and how it is tracking against the 1-hour ahead, 4-hour ahead and day-ahead demand forecasts. The latest demand forecasts for each region can also be viewed, which show the most recent demand forecast published by AEMO for the week ahead. There is also an average demand screen which shows the rolling 7-day, 14-day, 30-day and 90-day average demand for each region - useful for viewing how demand changes as the seasons progress. * The supply screen displays the current and historic electricity supply by fuel type. Each power station current electricity generation can be viewed in real-time. Behind the meter rooftop PV generation is also available. * Energy and FCAS dispatch prices for each region are displayed on the prices screen. This screen also shows price trends (volume weighted average prices and prices averaged by time of day) and a price outlook to see current price forecasts and the range of historic price forecasts. * NEM Tycoon game - create a conglomerate by buying a portfolio of power stations. Each conglomerate earns income based on how each power station performs in the NEM in real life. Compete with other Tycoons to see whose conglomerate can earn the most income. ## Key features - Dispatch overview map - Hour-ahead price outlook - Day-ahead price outlook - Week-ahead reserve outlook - Market notices - Demand overview and forecasts ## Recent user reviews (10 of 39) All indexed reviews: https://appshunter.io/ios/app/nem-data/id1509687648/reviews.md ### 1/5 — App broken *2026-05-07, version 2.1.1* Hi dev, app is totally broken! ### 1/5 — No longer works *2026-05-05, version 2.1.1* Unfortunately this app is no longer functional nor supported!
