Research Methodology

Desk research of EIA international energy statistics, ANEEL regulatory filings, and IEA power generation databases preceded structured interviews with utility planning officers, IPP project developers, EPC contractors, and fuel supply specialists. Primary fieldwork across São Paulo, Santiago, and Lima validated secondary projections through bottom-up capacity tracking and top-down demand reconciliation. Triangulation between project development databases and interconnected grid dispatch records anchored segmentation integrity.

Variance decomposition across fuel type, generation capacity tier, and regional grid type shaped the analytical framework over the projection horizon. CAGRs were derived through capacity-weighted averaging of segment-specific expansion trajectories. Modeled inputs incorporated LNG import terminal construction timelines, mining sector electricity intensity coefficients, and hydroelectric reservoir variability indices.

Forecasts assume regulatory continuity in ANEEL reliability standards and Chilean SEC emissions benchmarks; material policy shifts would require re-modeling. Specific risk factors include carbon border adjustment implementation, Argentine export pipeline regulatory reversals, and supercritical equipment procurement delays. Revision becomes warranted when Atlantic basin LNG spot price volatility crosses thresholds that compress combined-cycle operating margins below regulated return floors.
