| - The Imperial Irrigation District (IID) is an irrigation district that serves the Imperial Valley in Southern California. Established under the State Water Code, the IID supplies roughly 500,000 acres (200,000 ha) of Imperial Valley farmland with raw Colorado River water to support irrigation. In addition to providing irrigation, IID also supplies electrical energy to the valley. In 2009 under the agreement, IID completed the 23-mile concrete lining project of the All-American Canal to recover about 66,700 acre-feet of water per year for use by the San Diego County Water Authority.

| - The Imperial Irrigation District (IID) is an irrigation district that serves the Imperial Valley in Southern California. Established under the State Water Code, the IID supplies roughly 500,000 acres (200,000 ha) of Imperial Valley farmland with raw Colorado River water to support irrigation. In addition to providing irrigation, IID also supplies electrical energy to the valley. IID was formed in 1911 under the California Irrigation District Act to acquire the properties of the bankrupt California Development Company and its Mexican subsidiary. The IID was formed as a public agency, acquiring 13 mutual water companies in the valley which had developed and operated water distribution canals. The district is headquartered in Imperial, California. Prior to 1942, irrigation water delivered to the Imperial Valley was diverted from the Colorado River near Pilot Knob through Mexico to bypass the Imperial sand dunes west of Yuma and into the IID-operated Alamo Canal (also known as the Imperial Canal). Since 1942, water has been diverted at Imperial Dam on the Colorado River through the 82-mile All-American Canal, all of which the IID operates and maintains, although the structures are owned by the U.S. Bureau of Reclamation. Water from Imperial Dam serves the Yuma, Ariz. region as well as the Imperial Valley. The All-American Canal also delivers water from the dam to the Coachella turnout—a section east of Yuma that diverts water to the Coachella Valley Water District. Imperial Dam, located about 20 miles north of Yuma, contains four desilting basins which help remove silt and sediment from the river water so it can be delivered by gravity flow. The IID also remotely operates the Brock Reservoir, between El Centro and Yuma, by operating the inlet and outlet gates and regulating the amount of water diverted into the reservoir and returned to the main system. The IID is a key partner in the Quantification Settlement Agreement—a pack of several agreements among California water districts entered into in 2003 to help California live within its entitlement of 4.4 million acre-feet of Colorado River water a year. Water conserved through conservation projects under the QSA is made available for the Southern California Coastal communities (San Diego County Water Authority, Coachella Valley Water District and Metropolitan Water District of Southern California). In 2009 under the agreement, IID completed the 23-mile concrete lining project of the All-American Canal to recover about 66,700 acre-feet of water per year for use by the San Diego County Water Authority. IID's Energy Department provides electric power to more than 145,000 customers in the Imperial Valley and parts of Riverside and San Diego counties. Service to residents of the Imperial Valley and Coachella valleys includes the Imperial Valley cities of El Centro, Calexico, Holtville, Brawley and Coachella Valley cities including Mecca, Thermal, La Quinta, Coachella and Indio, Bermuda Dunes, Thousand Palms, Indio Hills and Sky Valley. As the third largest public power utility in California, IID controls more than 1,100 megawatts of power derived from a diverse resource portfolio that includes its own generation, and long- and short-term power purchases. Located in what's been referred to as the "renewable energy capital of the world", IID serves as a catalyst for renewable energy development in the Imperial Valley and is going to great lengths to enhance its energy infrastructure to be able to move renewable energy generated in the Imperial Valley to markets far and wide. The Energy Department has an aggressive transmission expansion plan and, over the next five years, intends to invest $1 billion in its energy infrastructure, which includes building a state-of-the-art energy battery storage unit in El Centro, which would provide back-up energy resources but also help the IID grid integrate the many megawatts of solar energy entering the IID grid during the day.
