TradeFlux

Every number, checked against your meter data

Import your data once. TradeFlux applies your tariffs, works out what you should have paid or been credited, and shows where the bills differ.

Bring the files you already have

Upload CSV or Excel exports from any meter or portal. TradeFlux guesses the columns, checks every interval and tells you exactly what it could not read.

  • CSV and Excel, with sheet selection
  • Column and timestamp format detection
  • Interval start or end, in any timezone
  • Gaps, duplicates and estimates flagged
  • Import history per location
Sample meter data import: a CSV with 2,880 rows is being mapped to TradeFlux fields, with 2,876 valid, 3 estimated and 1 missing reading.

Your tariff, modelled exactly

Start from an Eskom template or build your own: seasons, day types, TOU bands, demand and fixed charges. A new tariff year is a new version, so last year’s bills still check out.

  • Eskom Megaflex and Nightsave templates
  • Fixed, time-of-use and dynamic prices
  • Seasons, day types and public holidays
  • Versions by validity date
  • Check which period any moment falls in
Sample Megaflex tariff, 2026/27 version, with weekday and Saturday TOU schedules for the high and low demand seasons and energy rates per period.

What the bill should say

For each connection and billing period, TradeFlux turns half-hourly readings into energy, demand and fixed charges per TOU period, before the bill arrives.

  • kWh and rand per season and TOU period
  • Demand from kVA data, or estimated and labelled
  • Tariff year changes handled mid-period
  • Data gaps shown, never hidden
  • Every figure traced to its inputs
  • Rerun any month and keep the history
Sample expected charges for one connection in September 2026: energy per TOU period, network demand estimated from kWh, ancillary and service charges, a wheeling credit from Overberg Wind, and the expected total.

See exactly where a bill is wrong

Enter or upload the Eskom, municipal or trader statement. TradeFlux lines it up with the expected charges and flags every difference above your threshold.

  • Utility, municipal and trader statements
  • Rate, quantity and missing-line checks
  • Thresholds per organisation or connection
  • Open, acknowledged and resolved, with notes
  • PDF and Excel report to send on
Sample comparison of an Eskom bill against expected charges for September 2026. Three lines match, standard energy is billed on more kWh than metered, off-peak energy is billed at the wrong rate, demand differs from an estimate, and a wheeling credit is missing. The bill is about R53,000 higher than expected.

Coming next

Built on the same engine, in the order founding members ask for them.

Sample allocation of one wind farm’s September output across three offtakers by fixed share, capped at each site’s consumption, with 7 percent spilled and a 2.5 percent loss factor.

Wheeling allocation

Split one generator’s output across many offtakers by share or priority, capped at what each site used, with losses applied once.

  • Fixed share, priority or pro rata
  • Spilled energy tracked, not lost
  • Expected credit per offtaker and TOU period
  • Statements per contract
Sample hindsight optimisation for a site with a 400 kWh battery. On a typical weekday the battery charges off-peak and discharges in the two peak windows, cutting the September bill from R438,210 to R401,760.

Site optimisation

See the battery schedule that would have cut last month’s bill on your tariff, and test a bigger battery or another tariff before you commit.

  • Schedules within your battery’s limits
  • Energy and demand charges both counted
  • Scenarios side by side
  • Savings you can check by hand

From checked bills to a virtual power plant

The meter data and tariffs you verify today are what flexible assets are scheduled against tomorrow. TradeFlux is built to grow in that order.

  1. MeasureAvailable now

    Half-hourly meter data and tariffs, already checked for billing.

  2. Optimise each siteComing next

    Find the battery and solar schedule that would have cut your bill on your tariff, then plan the next month with it.

  3. AggregateLater

    Pool batteries, solar and flexible load across sites for licensed traders and aggregators as the wholesale market opens.

TradeFlux is software for licensed traders and aggregators. It does not trade or take ownership of electricity itself.

Sample virtual power plant portfolio pooling four sites into 0.94 MW of flexible capacity for peak shaving, TOU optimisation and demand response. On the roadmap.

Built in phases, with the people who use it

Founding members shape each phase before it ships, and the order follows what they need most.
