ONS (Operador Nacional do Sistema Elétrico) — Brazil's national electricity grid operator. Public Tempo Real REST/JSON feed, no credentials. Real-time national system load (SIN, ~77 GW), generation mix by source (hydro, thermal, wind, solar, nuclear), marginal operating cost (CMO) by submarket (Southeast/Center-West, South, North, Northeast) in R$/MWh, the energy balance snapshot (generation, load, import/export and interchange by submarket plus international ties with Argentina/Paraguay/Uruguay), and reservoir energy storage (EAR). Joins the power-markets family (ercot/spp/nyiso/caiso/aemo/cammesa/eirgrid).

Methods (6)

  • getSystemLoad

    read

    Live national (SIN) electricity load curve (MW), intraday series + latest point.

    No args. hourIndex is intraday hour offset, not a timestamp.

  • getGenerationMix

    read

    Live national generation by source (hydro/thermal/wind/solar/nuclear), MW.

    No args. Per-source intraday series + latest, plus latestTotalMw.

  • getMarginalCost

    read

    Marginal operating cost (CMO) by submarket (R$/MWh), half-hourly day-ahead.

    submarket: SE|S|N|NE (default SE).

  • getEnergyBalance

    read

    Per-submarket generation/load/import/export + international ties + interchange (MW).

    No args. Single timestamped snapshot (SE-CO/S/NE/N).

  • getReservoirLevels

    read

    Stored hydro energy (EAR) by reservoir/basin/subsystem + SIN total.

    subsystem substring filter: Norte|Nordeste|Sul|Sudeste. limit ≤1000. Daily.

  • getServiceInfo

    read

    Describe the key catalog, submarkets, sources, and probe reachability.

    No args. 24h cached service metadata.
