Interruptible Service

With the Interruptible Service rate, eligible commercial customers can receive a bill credit by agreeing to service interruptions that can help TEP manage energy resources efficiently, especially when the demand for power is high.

Participating customers will receive a bill credit for each of the five summer months when an interruption may occur. The length and frequency of outages are limited, and TEP will give customers a 30-minute notice before each interruption. Under this program, TEP can interrupt service at any time for any reason.

The monthly credit will be calculated using TEP’s Market Value Capacity Price (MVCP) and the amount of interruptible capacity, measured in kilowatts (kW), that participating customers agree to curtail. The MVCP based on the 2017 Market Index, was calculated to be a $1.215 per kW bill credit for the 2018 schedule.

Interruptible Service is available to customers using pricing plans designed for demand that exceeds 3,000 kW. Participants must agree to curtail at least 1,000 kW of electric demand at a single service point.

Participating customers are responsible for the expense, installation and maintenance of communication, relay and breaker equipment needed to qualify for service under this special rate. TEP must inspect and approve customer equipment. TEP is not responsible for any loss or damage caused by service interruptions.
