1. A method of forecasting power output of a wind energy facility, comprising:

  • ingesting one or more data sets representative of meteorological forecasts for an area in which a wind energy facility is located from at least one of multiple numerical predictive weather models;

    extracting weather variables from the one or more data sets having an expected relationship to a power output production generated by the wind energy facility;

    ingesting an actual power output data that is representative of historical power output of the wind energy facility for a specified period of time;

    applying, within a computing environment comprised of at least one computer processor configured to model a specific power output forecast for a wind energy facility within a plurality of data processing modules, the weather variables and the actual power output data to heuristically build one or more neural networks to infer non-linear relationships between the weather variables and the actual power output data of the wind energy facility to produce a specific power output forecast for each numerical weather prediction model;

    projecting a current time-series representation of power output of the wind energy facility to create a persistence power output forecast; and

    creating an ensemble average consensus power output forecast for the specified period of time from numerical weather prediction models and persistence power output forecast comprising ensemble members, each ensemble member having a weight determined by recent and real-time statistical assessments of an accuracy of each specific power output forecast for the wind energy facility.
