The method of claim 1, further including: if said additional site does not have sufficient data processing or manufacturing capacity or if said additional current AC frequency is less than said additional threshold AC frequency then determining if said task needs to be released for processing to meet a scheduled completion time and date and if said task needs to be released for processing to meet said scheduled completion date/time then performing said task at said site on a computer system or a manufacturing tool connected to said AC power grid. 5. The method of claim 1, wherein said threshold AC frequency is equal to or greater than a nominal AC frequency of said AC power grid and said additional threshold AC frequency is equal to or greater than a nominal AC frequency of said additional AC power grid. 6. The method of claim 1, further including: at an additional site powered by connection to an additional AC power grid, measuring an AC frequency of said additional AC power grid to obtain an additional current AC frequency;if said current AC frequency is higher than said additional current AC frequency, then performing said task at said site on a computer system or a manufacturing tool connected to said AC power grid; andif said additional current AC frequency is higher than said current AC frequency, then transferring said task to said additional site and performing said task at said additional site on a computer system or a manufacturing tool connected to said additional AC power grid. 7.

The method of claim 7, further including: if said additional current AC frequency is higher than said current AC frequency, and said additional site does not have sufficient data processing or manufacturing capacity to perform said task, and said task needs to be released for processing to meet a scheduled completion time and date then performing said task at said site on said computer system or said manufacturing tool connected to said AC power grid. 9. A method, comprising: receiving a request to perform a task at a site powered by connection to an AC power grid, said task either comprising data processing or manufacturing an article;periodically measuring an AC frequency of said AC power grid to obtain a current AC frequency;starting said task at said site on a computer system or a manufacturing tool connected to said AC power grid when said current AC frequency is equal to or greater than a threshold AC frequency;after said receiving a request to perform a task, said periodically measuring an AC frequency of said AC power grid and said starting said task at said site, then periodically measuring an AC frequency of said AC power grid to obtain a periodic AC frequency and if said periodic AC frequency is lower than said threshold AC frequency then stopping said task and restarting said task from where said task was stopped when said periodic AC frequency is again greater than said threshold AC frequency;while said task is stopped, determining if said task needs to be released for processing to meet a scheduled completion time and date; andif said task needs to be released for processing to meet said scheduled completion time and date, then restarting said task from where said task was stopped and completing said task with no further stoppages or transferring said task to an alternative site having the same capability to perform said task as said site, said alternative site completing performance of said task. 10. The method of claim 9, further including: continuing to periodically measure said AC frequency of said AC power grid to obtain said periodic AC frequency and if said periodic AC frequency is lower than said threshold AC frequency then stopping said task and restarting said task from where said task was stopped when said periodic AC frequency is again greater than said threshold AC frequency until said task is complete. 11. A computer system comprising a processor, an address/data bus coupled to said processor, and a computer-readable memory unit coupled to communicate with said processor, said computer-readable memory unit containing instructions that when executed by the processor implement a method for workload balancing to assist in power grid load management, said method comprising the computer implemented steps of: receiving a request to perform a task at a site powered by connection to an AC power grid, said task comprising either data processing or manufacturing an article;determining a current AC frequency of said AC power grid from frequency measurements of said AC power grid;issuing instructions to perform or not perform said task at said site based on said current AC frequency; andwherein the method step of issuing instructions to perform or not perform said task at said site based on said current AC frequency includes: if said current AC frequency is less than a threshold AC frequency, issuing instructions to determine if an additional site powered by connection to an additional AC power grid has sufficient data processing or manufacturing capacity to perform said task;if said additional site has sufficient data processing or manufacturing capacity, then determining an additional current AC frequency of said additional AC power grid from frequency measurements of said additional AC power grid; andif said additional current AC frequency is equal to or greater than an additional threshold AC frequency then issuing instructions to transfer said task from said site to said additional site. 12.
