ERCOT large loads (data centers and other 75 MW+ loads), peak demand records and forecasts, read from ERCOT's own documents: dataset 'monthly' = MW approved to energize and their observed peak per month (from April 2025); 'queue' = GW of large-load requests ERCOT is tracking and the data-center share; 'batch_zero' = ERCOT's conditional Batch Zero classification; 'peak_demand' = monthly and yearly peaks and record days; 'forecast' = ERCOT Long-Term Load Forecast summer/winter peaks (TSP-provided vs ERCOT-adjusted). Every value has its document URL; records are unofficial until final settlement. For the page with context see electricity_data_product slug 'large-load-demand'. Free (no key or free key): the most recent 30 days of each series; a Pro key unlocks full history. Values are exact as published with unit, date and original source URL; incomplete days are flagged, never filled. Free for non-commercial use with attribution; commercial use requires Pro.
