Frequently asked questions

What tariffs are supported?

All standard Spanish ATR tariffs: 2.0TD (residential, 3 periods), 3.0TD (commercial, 6 periods), and 6.1TD through 6.4TD (industrial, 6 periods).

What is indexed vs fixed pricing?

Indexed pricing assembles the final price from market components (OMIE + peajes + cargos + pérdidas + margin). Fixed pricing applies contractual per-period prices directly. You can compare both strategies for the same date range.

Where does the market data come from?

OMIE day-ahead prices from ESIOS (REE), loss coefficients from ESIOS archives, and regulatory parameters (peajes, cargos) from BOE official publications.

Can I upload my own consumption data?

Yes. Upload CSV, Excel, or Parquet files with your consumption data. The system auto-detects columns, normalizes to hourly kWh, and merges with pricing data for full cost breakdowns.

Can I try it online?

Yes. The interactive playground lets you upload consumption data and run calculations directly in your browser — no installation needed.

Is there a trial?

Yes. Contact us and we'll set up a trial so you can evaluate the billing engine with real tariffs and market data.
