Arlington electricity prices have decreased by 0.2¢ over the past 7 days for an average 1,000 kWh home. That’s about a $2/month decrease for the average family. With 119 plans available ranging from 7.9¢ to 23.56¢ per kWh, the market remains competitive. We don’t have a crystal ball, but when rates are trending down, it’s generally a good time to lock in a plan.
