Serena Energia (formerly Omega Energia) is a Brazilian renewable-energy company focused on wind, solar and hydro. Growing through acquisitions and its own development of utility-scale wind and solar, its installed capacity reaches about 1,869 MW. It supplies 100% renewable power and, through long-term power purchase agreements (PPAs), supports the decarbonization of global companies such as 3M. It is part of Brazil's shift as wind and solar first surpassed a third of monthly generation.

Serena Energia (formerly Omega Energia): Brazil's 100% renewable power (wind, solar, hydro). The letter is B; certainty is high. Unconfirmed concerns are placed under “Watching.” (As of 2026-Q3; estimate based on public information.)
Main narrative
One person’s story (N1)
+ A single story
People and future generations who want electricity free of fossil fuels. Serena Energia supplies 100% renewable power from wind, solar and hydro, supporting Brazil's renewable expansion. The benefit appears for nature and future generations: its installed capacity reaches about 1,869 MW, supporting decarbonization through corporate PPAs.

Watching (unconfirmed; not counted in the assessment)
- A listed, for-profit electricity company
- the land use and grid integration of large-scale wind and solar are watch items common to renewables.
Looking ahead (not included in the assessment)
- Adding wind and solar; grid integration and storage; care for land use of large renewables; contributing to Brazil's renewable expansion.
A second look
The plus is an effect on climate, nature and future generations through 100% renewable power from wind, solar and hydro, backed by the real scale of about 1,869 MW, 100% renewable and corporate PPAs. But it is a listed, for-profit electricity company, and the land use and grid integration of large-scale wind and solar are watch items common to renewables. Weighing the genuine, large-scale decarbonization plus, B/high.

How to read this assessment
A Independently verified +, with no confirmed −
B Leans +, with independent backing
C Mixed. A confirmed − sets the ceiling, or much is unverified
D A serious confirmed − sets the ceiling
E A serious − reaches the core of the organization
F Serious and systemic, with little redeeming +
G Only extreme cases
Out of scope An entity whose core purpose is illegal
On hold Independent evidence is scarce on both + and −
- Reachable upper bound (ceiling): a confirmed − sets the ceiling, and independently verified + decide the position within it. + do not cancel out −.
- The weight of evidence is not symmetric: only confirmed − are counted; the volume of disputes or allegations goes under “Watching.” + are counted from independent evidence, while an organization’s own PR is treated as “reference.”
- Size is not value: scale is not used in the assessment. Matters that stay within money or competition—investors, shareholders, sanctions, trade secrets—are also excluded.
- The letter (assessment) and certainty (how reliable the information is) are separate axes.
This is a translation; the Japanese version is authoritative. The assessments here are generated automatically by AI based on published criteria. The operator does not alter individual results. Because they are AI-generated they may contain errors, and they are opinion and commentary, not statements of fact. Where evidence is insufficient, the entry is marked “On hold.” Requests for correction are accepted via the form.
