Latin America’s power map has been redrawn.
Between 2015 and 2026, the old guard ceded ground to a new breed of aggressive consolidators. I tracked installed generation capacity across the top 25 operators in Latin America and the Caribbean. The shifts are striking.
The headline moves:
🟠 Auren Energia went from 1.8 GW to 8.8 GW — including a transformative 5.2 GW acquisition of AES Brasil (Oct 2024).
🟠 Cox Energy went from niche player to major operator by acquiring Iberdrola’s 2.6 GW Mexico renewables portfolio (Apr 2026).
🟠 Iberdrola executed the mirror image: sold ~11 GW in Mexico (8.6 GW gas to MIP, 2.6 GW renewables to Cox) to refocus entirely on Neoenergia Brazil — trading Mexican regulatory risk for Brazilian grid stability.
What the table shows that headlines miss:
Consolidation is happening fast — but not uniformly. Brazil is attracting scale. The Andes are attracting mining-linked corporate PPAs. Central America and the Caribbean are attracting gas-backed baseload. Each sub-region is running a different playbook.
Ownership structures matter enormously. These rankings use net equity-adjusted figures where disclosed — ENGIE’s 13.8 GW reflects actual proportional stakes, against a gross fleet of ~23 GW at 100%. Panama’s 670 MW Gatún CCGT illustrates this perfectly: ~161 MW net to AES (24% economic interest) and ~342 MW to InterEnergy (51% of the JV). The cap table is as important as the nameplate.
The conclusion:
The era of build-from-scratch is being eclipsed by growth-by-acquisition. In 2026, it is cheaper — and faster — to buy your neighbor than to permit a new plant. The next five years will likely accelerate this further as renewable economics tighten and grid interconnection becomes the binding constraint.
