Utility & Tariff

Notes

Otter Tail Power

Super Large General Service (Approved)

• Rate is designed to capture the marginal costs the utility expects to incur serving the customer's load; any additional unanticipated costs will be recovered through riders

Arizona Public Service

Extra High Load Factor (XHLF) Rate (Proposed/Pending)

​

• Proposed a new cost allocation method to directly assign new generation costs to serve growth based on the level of increased load each class experiences.
• Also proposed making XHLF tariff mandatory for “large-use customers requiring the procurement of new generation resources to serve their load.. not already in APS' resource plan..."

Evergy Kansas

Large Load Power Service (LLPS) Rate Plan and Associated Tariffs (Approved)

• Proposed a system support rider (a per-kW demand charge), minimum bill, early termination fee.
• Also proposed updating line extension policies to ensure large load customers pay all of the costs necessary to serve them.
• The plan includes optional tariffs to allow large load customers to receive bill credits for using their own capacity as Southwest Power Pool (SPP) capacity & using onsite generation for DR services.

Georgia Power

Rules and Regulations
