WHY WERE ELECTRICITY PRICES RISING WHILE NATURAL GAS IS FALLING?....

While doing my homework last week for the recent switch of providers, I noted several REPs had raised their prices two to four mils (tenths of a cent) during the week.  Were their actions justified?  Natural gas prices were falling to $3.83 during the same period.  Did wholesale costs of electricity increase or did the REPs again profit on the fears of some due to events in Libya and the rise in oil and gasoline prices?  PROVIDE YOUR COMMENTS.
