Automate power & gas trade matching, settlement reconciliation, ISO/RTO reporting, and compliance logging.
A production-focused resource for engineers and analysts who turn raw market data into reconciled, audit-ready settlements. Here you will find deterministic patterns for power and gas trade matching, ISO/RTO reporting, settlement calculation, ETRM system sync, regulatory filing prep, batch validation, and audit logging.
Every guide is built around real Python workflows — vectorized pandas pipelines,
schema-validated ingestion, header-aware async clients, and idempotent reconciliation
engines — so that settlement variances are caught before they reach the general ledger.
The material targets energy traders, settlement analysts, utility operations teams, and
the automation builders who keep their pipelines running.
The hub is organized into four sections that follow data from ingestion through calculation and architecture to regulatory filing. Start anywhere — each section links to deep, hands-on guides.
Energy settlement reconciliation breaks the moment two systems disagree about what a megawatt-hour is worth, when it was delivered, or which node it settled…
Energy markets dispatch generation at sub-second resolution, yet financial settlement runs on daily, monthly, and preliminary-versus-final cycles — and the gap…
A single day-ahead award that lands in your ETRM as 2026-03-08T02:30:00 — an hour that does not exist on the US spring-forward date — is enough to leave a…

Open sectionNew to the hub? These hands-on Python walkthroughs are the most direct way in — each one takes a real settlement task from raw market data to a reconciled, audit-ready result.
A settlement re-run for a trading day two months old maps a meter to pnode AECOLOAD, but that node was re-parented from the AECO zone to PSEG three weeks ago —…
