something for nothing
TXU Energy in Texas now has free energy between 10 PM and 6 AM. The first utility in the nation to go to Zero rate at night. TXU has lots of wind generated energy, and in their location the wind blows almost all night every night, when demand is the lowest. Some power they make at night goes unused. During daylight hours demand often exceeds supply. Rather than build more capacity TXU believes they can change customers habits by giving away power.
With a little adjustment, people can start the laundry and go to bed, new dishwashers have delayed start settings, run them at night for free, crock pots can run at night, charge all your toys at night, even your new electric car. TXU believes they can move 10% of the demand to night time. Their customers can save money, and TXU can delay building more capacity.
