Methodology

Methodology & Limitations

This page documents how numbers are made from ENTSO-E and TSO data, and what they cannot tell you. Built by a practitioner, shared freely.

How the numbers are made

Data First. AI Second.

Three layers separate raw data from the intelligence you receive. The AI writes the story — it never invents the numbers.

01 — Data Ingest
Five Institutional Sources
Every analysis starts with measured, verifiable data from official European energy institutions — not scraped, not estimated.
Fraunhofer ISE · 1s frequency ENTSO-E · prices & flows PVGIS 5.2 · solar irradiance GOPACS · SMARD · Elia Open-Meteo · weather
02 — Deterministic Compute
Algorithms, Not Guesswork
Every number in every report is produced by deterministic statistical pipelines and standards-grade formulas. Reproducible. Auditable.
SciPy / NumPy pipelines Day-ahead price statistics Congestion & redispatch analytics SOGL threshold detection
03 — AI Narrative
AI Writes the Story, Not the Numbers
AI interprets the computed results — explaining why frequency dropped, what drove prices, or where congestion risk is building. Context, not fabrication.
Grid event root-cause analysis Market trend interpretation Operational briefings · 200 words

Every number in our reports comes from measured data processed by deterministic statistical algorithms. AI generates narrative text only — never the data. You can always verify our analysis against the source datasets.

Honest Positioning

What this resource can't tell you

×
Need real-time trading execution or asset control

Grid Compass monitors frequency, detects stress events, and delivers AI root-cause analysis; our market reports provide weekly and monthly intelligence for NL, DE-LU, BE, and FR. But we're an insight layer — not an operational platform. We don't control DER assets, optimise VPP dispatch, or stream tick-by-tick trading data. We push intelligence to the edge of the grid — operators, traders, and analysts make the decisions.

×
Need bespoke consulting or a custom data model

This is a personal educational resource, not a consultancy. You get standardised reports and dashboards built on ENTSO-E and TSO data — freely available. Custom modelling engagements aren't what we do.

×
Need markets outside NL, DE-LU, BE & FR

Our market analytics and grid intelligence cover four bidding zones today. If you need other European markets, we're likely not the right fit yet.

Quality & Accountability

How the data is validated

What each dataset stands on, what we guarantee, and where the qualified professional picks up.

Market Intelligence · 4 Bidding Zones
Quasar Intelligence
EU electricity markets — historical + forward outlook
Weekly Market Snapshot
ENTSO-E · 7-day rolling
Monthly Deep-Dive
ENTSO-E · 30-day synthesis
Forward Outlook
Statistical 7-day outlook · not a trading signal

Historical data sourced from the ENTSO-E Transparency Platform with snapshot timestamps on every chart. Forward outlooks are a statistical 7-day projection — not a trading signal.

NL · DE-LU · BE · FR only · zones outside scope not covered
Real-Time Dashboards
Grid Compass

Live TSO feeds with balancing activation analytics and imbalance-spread decomposition. Every panel shows source and last-update timestamp. Free with a Quasar account.

4 EU zones · freshness ≤ TSO publication lag
Weekly Grid PDF
Grid Pulse

Deterministic statistics computed from archived TSO data for the prior 7-day window. AI narrative synthesises the deterministic statistics — never adding numbers.

Prior 7 days only · not real-time
Conversational · Grounded
AI Grid Analyst

Tool calls over live TSO data. Every answer cites source and timestamp. If a number isn't retrievable, the bot says so — it never fabricates. Community grant — dashboards stay free with your account.

Community grant · 50 Q / month · no forecast beyond day-ahead curve
What We Guarantee

Every numerical output traces deterministically to a cited standard or authoritative data source. The AI layer never introduces unsourced numbers. Delivery within the stated turnaround. GDPR-compliant processing throughout.

Where the Professional Picks Up

Final design sign-off, DSO or permit acceptance, local code compliance, and on-site conditions remain the responsibility of the qualified professional applying the output.
