Notice

Summary

The Colorado River Storage Project (CRSP) has new formula rates ready if it joins the Southwest Power Pool (SPP). These updated rates will replace the old ones for transmission and related services, affecting customers who use CRSP’s power lines. The changes kick in only if CRSP becomes an SPP member, with current rates staying put until the end of 2028.

Analyzed Economic Effects

2 provisions identified: 1 benefits, 0 costs, 1 mixed.

New CRSP Transmission Formula Rates

If CRSP decides to join the Southwest Power Pool (SPP), new interim formula rates for transmission and ancillary services (Rate Schedules CRCMT-ATRR, CRCMT-AS1, and CRCMT-PTP) will be placed into effect. These new formula rates will replace the existing transmission and ancillary service formula rates listed in the notice once CRSP becomes an SPP member.

Current Rates Remain Through 2028

The existing CRSP transmission and ancillary service rate schedules will remain in effect until they expire on December 31, 2028. Any replacement by the new CRCMT- series formula rates will occur only if CRSP becomes an SPP member, so customers keep current rates through December 31, 2028 unless that membership condition is met earlier.
