Generation seasonality and industrial operating risk
- Energy, water and telecommunications
- The power market and its tariffs
- not audited
Seasonality is strong and is best modeed as an operating risk. In May 2025, at the close of the dry season, coal supplied 29% of generation, hydro 24.2% and bunker fuel 15.2%; in October 2025, in the middle of the rainy season, hydro reached 66.3% (766.22 GWh). It is the thermal mix of the dry months that pushes the spot price up, as it did in 2024.
The research is written in English; quoted figures, source names and the titles of legal instruments stay in the language their source published them in.

This layer is research: read from public sources by the archive's own team, every claim cited with the date it was consulted, and audited where it is marked so. It has not entered the verified store — no figure here was fetched back from its source or stamped with a retrieval time — so it wears no red provenance numeral and never mixes with the verified figures.
