This is FASCINATING. Researchers were able to pin down the cause of measurable global 60 second power spikes to software that does regular checks on the minute mark. They found large scale battery installations as one major cause, but obviously this is true for any other computerized system that does cron jobs and has a synchronized clock. As weird as it sounds, adding random 0-59.999s delays to cron jobs in Linux distributions and other software would actually help the power grid.

Mystery of 60-Second Fluctuations in Power Grids Solved Why do our grids show a brief spike in electricity demand every minute? A team led by Dirk Witthaut from Forschungszentrum Jülich has now demonstrated that this is due to regular power checks carried out by large-scale battery storage systems. These findings could help to make our electricity supply more robust, as the team reports in an article published in Nature Energy.

@hzulla i can add to this story ;) We once had a service that was integrated into every Windows Mobile that also stupidly checked in our service on a fixed clock. That wasn't a problem as long as Windows Mobile didn't had NTP. But then suddenly Microsoft added that feature and after a short time all phones suddenly had accurate time and DDOSed our service on the fixed interval.....
