Sugar Land electricity prices have edged up about 0.1¢ per kWh over the past 7 days, which comes to roughly $1 a month for an average 1,000 kWh home. The current average market rate is 15.05¢/kWh, with 121 available plans ranging from 7.0¢ to 22.02¢ per kWh across the Greater Houston service territory. The spread is wide, so plan terms and structure matter more than the small weekly move.
