Southlake electricity prices have decreased slightly by 0.1¢ over the past 7 days for an average 1,000 kWh home. That’s about a $1/month decrease. With 117 available plans ranging from 8.08¢ to 22.84¢ per kWh, the market remains competitive. If you’ve been considering switching, a downward trend is typically a good time to lock in rates.
