Looking at PG&E's sources of energy, 60% comes from easily controllable sources like gas, nuclear, and hydro.
40% comes from wind, solar, and other that are not so easily regulated. Steam generators can't me moved thermally as fast as winds drop or clouds develop. Then there is the load side, with who knows what equipment making large swings. It would be interesting to hear from other parts of the country, but cycle-watching hasn't caught the interest of this group yet.

Jan 20, 2014, Wed http://www.megapathdsl.net/~hmurray/time-nuts/60Hz/2014-Jan-29-a-dip.png I think this is the biggest dip I've seen, down below 59.8 Hz. That's averaged over 10 seconds. Feb 02, 2014, Sun http://www.megapathdsl.net/~hmurray/time-nuts/60Hz/2014-Feb-02-a-dip.png This one got below 59.9 Hz. I guess I should write some code to scan the archives. I wonder how many similar glitches I've missed. The last 50 days days: http://www.megapathdsl.net/~hmurray/time-nuts/60Hz/Dec-2013.png Peak-peak offset is 15 seconds. -- These are my opinions.
