Salt River Project Agricultural Improvement and Power District, commonly known as SRP, is a public utility headquartered in Tempe, Arizona. Founded in 1903 with the establishment of the Salt River Valley Water Users' Association, the District itself was created shortly after 1936 as a political subdivision of the state of Arizona. As a government-owned corporation, SRP is not publicly traded. In fiscal year 2023, the company reported revenues of US$4.02 billion and had 5,123 employees.
SRP serves as a primary provider of electricity to over 2 million people in the Phoenix metropolitan area and supplies water to much of central Arizona. Its operations encompass a diverse portfolio of power generation resources, including coal, natural gas, hydroelectric, solar, wind, and nuclear facilities. Additionally, SRP manages an extensive water delivery system, which includes reservoirs, canals, and irrigation infrastructure crucial for agriculture and urban development in the region. The utility is also engaged in promoting energy efficiency and sustainable energy practices.
In terms of patent litigation, Salt River Project Agricultural Improvement and Power District maintains a defensive posture, with no tracked cases as a plaintiff and one case as a defendant. This indicates its role as an operating company that faces patent assertions. The company's sole tracked case, "Midwest Energy Emissions Corp. et al. v. Berkshire Hathaway Energy Company et al.," is consolidated under a multi-district litigation (MDL No. 3132) in the Southern District of Iowa.
This notable case involves allegations from Midwest Energy Emissions Corp. (now known as Birchtech Corp.) regarding the infringement of patents related to mercury emission control technologies used in coal-fired power plants. As SRP operates several power generation stations, including coal-fired plants, it is among multiple utility companies defending against these patent claims within the consolidated MDL.
