Research Highlights

Granular data analyses revealing what aggregated reports hide

Numbers That Matter

Findings with direct commercial, regulatory or technical implications

87%

Surprise Curtailment

NEWAVE-DECOMP-DESSEM schedule ZERO. 87% of curtailment is managed manually in real time.

R$ 1.77B

Invisible Congestion

Hidden annual cost of the NE→SE bottleneck. CMO spread between subsystems × curtailed energy.

27x

Daily Floor (P10)

Daily curtailment minimum jumped 27x in 1 year. Present 99% of hours. Became baseload.

11

States Affected

No longer just a NE problem. MG solar +469%, SP emerging. 3 distinct geographic fronts.

-41%

Concentration (HHI)

Curtailment deconcentrated. Top 5 clusters: from 17% to 10%. Became a systemic problem.

2.4x

BESS Value vs Volume

Optimizing battery by value (CMO) yields 2.4x more revenue than by volume (curtailed MWh).

471 GWh

One Equipment Offline

150 Mvar compensator in MG causes 471 GWh of curtailment 2,000 km away. R$ 115M in 116 days.

57 TWh

2030 Projection

Base scenario with logistic saturation. +49% over 2025. MG solar: biggest mover (+81%).
