Client in Phoenix just got hit with a massive increase in SRP delivery charges. They're on Schedule E-65 and the delivery portion of their bill went from $0.045/kWh to $0.089/kWh overnight. SRP is claiming it's due to "infrastructure modernization costs" but there was no advance notice to customers. The client has a 3 MW solar installation and I'm wondering if this is SRP's way of discouraging distributed generation. Anyone else seeing similar increases from SRP?
Arizona - Salt River Project delivery charges doubled
Alan, that's a huge jump in delivery charges. Here in Texas we've seen utilities try to recover grid modernization costs but usually there's a rate case or at least a rider filing first. Arizona Corporation Commission should have had to approve those increases. SRP is a little different since they're a public power entity but they still have oversight. Doubling delivery charges without notice sounds like it could violate their own tariff procedures.
Alan, SRP has been aggressive about cost recovery lately, especially for customers with solar. They've been claiming that distributed generation customers aren't paying their fair share of grid costs. But a 98% increase in delivery charges overnight is extreme even for them. I'd check if they filed an amended tariff with proper notice requirements. Also worth seeing if other Schedule E-65 customers got hit with the same increase or if your client was singled out for some reason.
