Your Imperial Irrigation District now offers an optional new time-of-use (TOU) electrical rate for residential customers, giving them the opportunity to save. The TOU option encourages customers to shift energy use during the greater part of the day when the rate is lower; it also encourages implementing energy-saving practices during the on-peak hours. Non-participants will have the standard residential rate of 19.76¢ per kWh.

In January 2025, the Imperial Irrigation District Board of Directors approved the new Time-of-Use (TOU) rate structure to give customers more control over their energy usage and costs. View the January 21, 2025 Board Meeting where TOU rates were approved.
