I have added two plots or graphs from smart meter data to my website at http://beta-a2.com/energy_c.html . These are PE1 and PE2 near the end of this website page.
The bargraph PE1 is a simulation of what can be seen on-line at my DTE account under Energy Use Analysis. This is classified as an "Hourly Use (bar chart)". Shown is the calendar week plot. I have defined a time period when there is virtually no activity except for loads that are on all throughout a day as "sleep time". Getting an idea of an average value for sleep time provides an estimate of average base load.
If base load seems high, then an analysis of what constitutes base load may prove useful in eliminating some unnecessary components.
The second plot, PE2, is not available on the DTE site. A similar one is called "Compare hourly use".
PE2 is generated from data downloaded from the DTE website. This consists of two different plots overlaid on the same coordinates.
The first plot is a number of dots. Each dot represents the energy used at a particular hour in a day and is centered in the hour to which it applies. Thus, at a particular hour there is one dot for each day of the time frame covered by the plot. In this plot the time frame is Sunday 4-28-13 thru Saturday 5-18-13. The vertical distribution of dots provides a view the variance at a particular time of day.
The second plot is a step graph of the average energy used at each hour for the time frame. In other words, all the dots in a given hour are added together and divided by the number of dots within said hour to provide the average value plotted in the step plot. This may be a very good way to estimate base load.
How many of you have smart meters and made any use of on-line data from your power company? Has this kind of data helped you reduce your energy use?
