As a not-for-profit, SRP doesn't have investors or shareholders. Instead of creating profits for investors, we put extra revenue back into improving water and power infrastructure and services for our community. This helps customers pay about 18% less than other Arizona utilities. Because SRP — unlike other Arizona utilities — is not regulated by the Arizona Corporation Commission, its independently elected officials have the sole authority to set electricity rates, approve major infrastructure investments and determine solar policies.
Cyborg Score Rationale
SRP holds the highest credit rating in the country as a not-for-profit utility, operates reliably across a 13,000-square-mile service area, and is actively modernizing its grid and solar infrastructure. Recent governance shift to clean-energy majority signals strong commitment to decarbonization and renewable integration, though political volatility in board elections presents operational uncertainty.
Top Insights
In April 2026, a pro-clean-energy slate secured majority control of SRP's power board for the first time in the utility's 120+ year history, signaling strong customer demand for renewable energy policy.
In April 2026, SRP commissioned its first utility-owned 55 MW solar facility at Copper Crossing, marking a strategic shift from third-party power purchase agreements to direct asset ownership and control.
SRP aims to reduce carbon intensity by 82% by 2035 and reach net-zero emissions by 2050, with a planned 2 GW solar expansion program.
Governance through elected landowner-based boards rather than a state regulatory commission gives SRP unique autonomy over rates and policy, but creates unusual political dynamics as demonstrated by record 36,000+ voter turnout in April 2026 election.
