I have been gathering price histories from the UK wholesale power market APX to use in future scenarios for the retail level. I noted that it is interesting to look at patterns between months, for example January 2012 vs. May 2012:

Above is January, below is May 2012. Each line is the price over one specific day in that month, themonthly average is indicated by a black dotted line. There are basicly two peaks during a day, during office hours and in the evening, when people come home.

The most interesting takeaway for me is that the variance in the data is much lower in January than in May. Also, in January the average price is lower during the day, but higher in the evening than in May.
