What Salt River Project does
Salt River Project (SRP) is one of the United States' largest publicly owned, not-for-profit electric and water utilities, headquartered in Tempe, Arizona, and operating exclusively within a designated service territory in central Arizona. Founded in 1903, SRP is legally structured as a political subdivision of the State of Arizona (the Salt River Project Agricultural Improvement and Power District and the Salt River Valley Water Users' Association), is owned by its customers and water shareholders, and is governed by an elected 14-member board. SRP delivers electricity to approximately 1.2 million residential, commercial, industrial, and agricultural accounts and supplies roughly 260 billion gallons of water annually to the Phoenix metropolitan area, with rates reported 37% below peer Southwest utilities and #1 reliability among large utilities in the region per 2024 EIA SAIDI data.
SRP's generation portfolio is diversified across natural gas, coal, nuclear, and a rapidly expanding renewables and storage mix - including 1,570+ MW of battery storage and 1,560+ MW of solar capacity in operation, with major PPAs and ESAs extending this to multi-gigawatt solar and multi-gigawatt-hour storage additions through partnerships with NextEra (3 GW solar + 1 GW storage), Enlight / Clēnera (1.2 GW solar + 4 GWh storage at the CO Bar Complex), Aypa Power, Invenergy, and EDP Renewables. The utility is also piloting novel long-duration storage technologies via Energy Dome's CO2-based battery (19 MW, 10-hour) and ESS Tech's iron flow battery (5 MW, 50 MWh), with Google participating as a cost-sharing partner. Grid modernization assets include advanced metering infrastructure, demand response (Bring Your Own Thermostat), customer-side solar and battery integration (SRP Battery Partner), and EV charging programs.
Commercially, SRP operates under a regulated, subscription-style revenue model where rates are set through a public pricing process to cover costs rather than generate shareholder returns. Customer revenue streams include flat-rate residential tariffs, time-of-use price plans, the M-Power prepaid program, Budget Billing averaging, and income-qualified discounts, alongside transmission and distribution services for commercial and industrial customers. Go-to-market leverages owned T&D infrastructure within its exclusive franchise territory, complemented by digital self-service through My Account and three dedicated mobile apps (SRP Power, SRP M-Power, SRP Water), 24/7 phone support, and over 900 retail payment locations across the Phoenix Valley. Commercial customer development is increasingly targeted at high-growth data center load (representing roughly two-thirds of large-business demand growth), with economic development outreach as the primary commercial acquisition channel.
