Port Lavaca 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. With 114 plans available ranging from 7.0¢ to 23.35¢ per kWh, the market is showing some downward movement. We can’t predict where rates will go, but if you’re considering switching, a declining trend might be worth acting on.
