real time power grid frequency map

[Mitch Buchman]

Cool indeed.

Any ideas on what is causing the oscillations in SE Pennsylvania. About
every 6-120 seconds there appears to be a 0.03 Hz dip or spike in
frequency. Maybe looking at an estimate of power consumption in 1/2 the
state and look at the 0.03 Hz change in potential <-> kinetic energy might
be interesting.

According to:
http://www.ferc.gov/market-oversight/mkt-electric/pjm.asp#gen
in 2009 there was a generating capacity of approximately 169,000 MW.

The 0.03 Hz swing corresponds to about a 75 MW swing, discounting damping
through the system.

Temperate weather, about 60 degrees F right now. Evening, with reduced
power consumption. Should still only get it to about a 30 MW swing.

What am I missing? Any other explanations?
