GasBrazil.com — Wiki

GasBrazil.com is a family of Brazilian natural-gas market dashboards — ONS grid balances, PEG capacity-offer results and contracts, ANP pipeline flows, CCEE electricity settlement prices, ANP gas-price disclosures, the national supply balance, and a cross-product desk view — plus the home page and this wiki. Every dashboard is a single self-contained HTML file with an embedded, gzip-compressed data payload: no server, no database, no API call at view time.

This wiki covers what each dashboard's own README doesn't: how to read the live page, and where a number on it rests on an assumption rather than a published figure. It's organized in two layers — this Home page and Architecture and Deployment cover the whole site, and every dashboard has its own Using the Dashboard and Known Limitations pair covering what's specific to it.
