Curtailment MWh by month — stacked by cause class
Curtailment R$ by month — stacked by cause class (CMO proxy)
Curtailment MWh by month — split by source (EOL / UFV)
R$ figures use ONS CMO Semi-Horário as a PLD proxy. During 2023 the PLD floor sat at ~R$69/MWh while CMO hit ~R$6/MWh for most of the year, so pre-2024 R$ values are materially understated. Wire CCEE PLD horário to reprice the backlog economically.
