Arbitrage CSV Mapper & Merger

Upload your two CSVs, preview the headers, then map the right columns. After that, merge to add SEK/MWh.

Guided Workflow

  1. Load energy prices: In panel 1, pick your Nord Pool CSV and map the interval and price columns.
  2. Load FX rates: In panel 2, upload the EUR/SEK CSV and confirm the date and rate fields.
  3. Merge & review: Click Merge & Compute SEK/MWh to preview the combined table.
  4. Export data: Download the merged CSV for version control and/or send it straight to the simulator.
  5. Run simulator: Scroll down to the simulator workspace, load the merged rows, and walk through the modelling steps.

Tip: keep DevTools open with “Disable cache” while iterating so you always load fresh scripts.

Arbitrage Simulator

Load the merged SEK/MWh price table below and walk through the 15 minute timeline, Swedish villa load model, battery controller, KPIs, and exports — no extra tab required.

Quick Checklist

  1. Load price data: Use “Load last merge” or paste CSV, then confirm the ingest status banner.
  2. Build timeline: Click Build 15-min timeline and glance at the preview table.
  3. Generate load: Enter annual kWh and create the Swedish villa profile.
  4. Configure battery: Adjust controller sliders for your scenario.
  5. Run simulation: Execute, study KPIs, daily rollups, and export if needed.

Tip: the ingest banner always shows the active period so you can spot missing data early.
