Brazil's hydro-dominated grid gives it some of the lowest-carbon compute outside the Nordics, but São Paulo's own reservoir crises make water the pressure point. The 2014–15 drought remains the reference case locally.
Water and air figures are modelled from disclosed capacity, not measured — site-level
error is roughly ±40%. Diesel backup generators are not counted, so on-site figures are floors.
