Who We Are

BrazilGrid is a research and intelligence platform focused on the power sector. Founded by Breno Loureiro, director of Brik Engenharia with ~20 years of experience in the wind and solar sector, having certified over 10 GW of renewable projects in Brazil.

The platform was born from a realization: power sector data in Brazil is public, but nobody analyzes it with the necessary granularity. ONS publishes half-hourly data per plant. CCEE publishes hourly prices per submarket. ANEEL publishes generation and permit records. By cross-referencing these sources with analytical rigor, we uncover patterns that aggregated reports hide.

Methodology

Every BrazilGrid analysis follows a hypothesis protocol:

Formulate explicit hypothesis (H##) with testable claim
Query granular data in ClickHouse (186 tables, 648M+ records)
Quantitative validation: correlation, statistical significance, temporal decomposition
Cross-validation: multiple subsystems, months and sources
Document result with status (Confirmed / Partial / Refuted / Inverted)
Publish article with finding + practical implication

Data Sources

ONS — Public S3 data: half-hourly curtailment per plant, CMO, interchange, scheduling/forecast, capacity factor, thermal generation
CCEE — Hourly PLD per submarket
ANEEL — SIGA (permitted/under-construction capacity), RALIE, SAMP (distributed generation), meeting minutes
SINtegre — DESSEM decks, NEWAVE definitions, DECOMP results, wind forecast, PV functions
Receita Federal — Corporate data (CNPJ, shareholders) for ownership mapping

Tech Stack

OLAP — ClickHouse Docker (production EC2 + local development)
Graph — Neo4j Enterprise (SIN topology: 7,100+ nodes, 12,900+ relationships)
Language — Python 3.11+ with Polars, Plotly, Streamlit
ML — XGBoost, LightGBM (surrogates and D+1 predictors)
API — FastAPI (Oracle API, 15 endpoints, SHA-256 per response)
