Providing efficient energy through the effective management of power resources in Arizona

Notice of Power Cost Adjustment -

Pursuant to the Bureau of Indian Affairs regulations governing our electric power utilities, found at 25 CFR 175, notice is hereby given that the San Carlos Irrigation Project (SCIP) is adjusting the purchased Power Cost Adjustment (PCA) component of our rates. Effective March 1, 2026, the PCA will be removed. Our existing electric power rates published in the Federal Register (87 FR 77628, Dec. 19, 2022) remain in effect.


SCIP completed its periodic review of power supply costs for calendar year 2025 and projected power costs for 2026 and determined that a removal of the PCA is appropriate. We will continue to monitor energy rates and adjust the PCA as needed to meet our financial and statutory requirements.


Please direct questions via e-mail to scippca@bia.gov or mail to San Carlos Irrigation Project, P.O. Box 250, Coolidge, Arizona, 85128.
