TXU Free Nights plan (just switched) UPDATE! With one plug-in vehicle, and a second on the way, I started digging into this TXU plan. My Reliant Power Tracker Plus plan was changed on me and I was getting hit with ~13 cents per Kwh. After several hours of spreadsheet magic, I concluded that I would be saving about 15% without even modifying my energy usage. The gist of the TXU free nights is this: 17.1 cents per Kwh 100% free from hours 10PM-6AM $10 monthly fee Normal taxes apply Here's what I have planned now that I have a nice, fat window to play in: 1. Only charge the cars after 10PM 2. Dishwasher and laundry timed for after 10PM 3. Modify the pool's pump to do its big filter cycle and chlorine generation from 11PM-6AM. Have two 30min skim cycles during the day. 4. Crank the AC down a bit from 10-6. 5. It seems small, but charging portable electronics after 10PM (including power tools) This will be a fun game to play this summer, too.
