As promised in the last update, sample datasets that include both zip code and energy cost are now posted at http://energy.gov/downloads/green-button-sample-data-pge. The four new files cover two small businesses, a residential account using a time of use plan, and a residential account paying a flat rate. Look for the files ending with " zipcode cost".
Also, a few of you noted that my math was off in the last update. The difference between Eastern and Pacific time is 10800 seconds.
