CENACE (Centro Nacional de Control de Energía) — Mexico's grid operator / ISO. The canonical Mexican wholesale-power PML feed (Precios Marginales Locales / Locational Marginal Prices). Public PÚBLICA web service, no key. Hourly LMP per node for day-ahead (MDA) and real-time (MTR) markets, with energy/loss/congestion components. Systems: SIN (national grid), BCA (Baja California), BCS (Baja California Sur). upstream quirks: non-standard port 8082; hard 7-day date-range cap per request (getNodePriceSeries chunks longer histories); node keys are system-specific (a SIN key under BCA returns ZERO_RESULTS); no node-catalog endpoint; Spanish field names; price strings parsed to numbers.
