Want more control over your electric bill? Imperial Irrigation District (IID) offers an optional Time-of-Use (TOU) rate that can help you save by adjusting when you use electricity — with peak times that vary by season.
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.
