NOVELTY - The method involves determining (260) atmospheric or environmental factor influencing wind generation capability for a region associated with an online electric power grid. Near term wind generation capability of a wind power generation system is determined (270) based on the atmospheric or environmental factor. A power grid spinning reserve forecast requirement is determined (285). Instructions to adjust power generation of non-wind power generators are provided (290) based on the near term wind generation capability, spinning reserve margin, and/or the forecast requirement.    USE - Method for preemptively adjusting power generation of a non-wind power generator e.g. gas turbine generator, steam turbine generator, battery pack and capacitor bank, based on near term wind generation capability, spinning reserve margin, and/or power grid spinning reserve forecast requirements to offset wind power generation based on geospatial regional wind conditions e.g. wind speed, wind direction, icing on wind turbine blades, lightning strikes, and wave height for off-shore units (all claimed).    ADVANTAGE - The method enables providing instructions to adjust the power generation of the non-wind power generators based on the near term wind generation capability, the spinning reserve margin, and/or the power grid spinning reserve forecast requirement such that grid spinning reserve losses are minimized by reducing the reserve margin while maintaining sufficient spinning reserve to meet anticipated peak loads, thus improving power generation asset manager decision fidelity.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for an electric power system.    DESCRIPTION OF DRAWING(S) - The drawing shows a flow diagram illustrating a method for preemptively adjusting power generation of a non-wind power generator to offset wind power generation.
