About this bond

What it is and who needs it.

What the UniSource deposit bond actually does

UniSource Energy Services is the trade name of two Arizona public service corporations regulated by the Arizona Corporation Commission (ACC): UNS Electric, Inc., which serves electric customers in Mohave and Santa Cruz counties, and UNS Gas, Inc., which delivers natural gas in Mohave, Yavapai, Coconino, Navajo and Santa Cruz counties. Each company’s Commission-approved Rules and Regulations let it require a deposit from any present or prospective customer to guarantee payment of all bills.

Both tariffs — Sheet 903, Section 3, Establishment of Service — give you an alternative to cash: “A surety bond may be provided as security for the Company in an amount equal to the required deposit.” The bond runs to UNS Electric or UNS Gas as obligee and guarantees payment of your utility charges up to the bonded amount. If the account goes unpaid, the utility recovers against the bond instead of a cash balance it would otherwise be holding.

The deposit, and so the bond, is sized to your own usage. Residential deposits cannot exceed two times your estimated average monthly bill; non-residential deposits cannot exceed two and one-half times your maximum estimated monthly bill, based on weather-adjusted usage history where it exists. Residential deposits or other instruments of credit expire after twelve consecutive months of on-time service; non-residential deposits are reviewed after twenty-four months.

It is not insurance for you. If the surety pays UniSource, you repay the surety. The benefit is cash flow: the deposit stays in your business instead of sitting with the utility for a year or two.

UNS Electric & UNS Gas Rules and Regulations, Sheet 903 · A.A.C. R14-2-203 / R14-2-303UNS Electric, Inc. Rules and Regulations, Sheet No. 903, Section 3.B.1.c (effective February 1, 2024, Decision No. 79277), and the identical UNS Gas, Inc. Sheet No. 903, Section 3.B.1.c (effective March 1, 2026, Decision No. 81653), provide that a surety bond may be provided as security for the Company in an amount equal to the required deposit. Section 3.B.7 caps residential deposits at two times the customer’s estimated average monthly bill and non-residential deposits at two and one-half times the customer’s maximum estimated monthly bill. The Arizona Corporation Commission’s own rules, Arizona Administrative Code R14-2-203(B) for electric utilities and R14-2-303(B) for gas utilities, likewise allow a new applicant to provide a surety bond as security in lieu of a deposit, apply the same two-times and two-and-one-half-times caps, and require each utility’s refund policy to let residential surety bonds expire after 12 months of service if the customer has not been delinquent more than twice. Confirm the exact deposit amount on your UniSource deposit notice.

After you buy

Claims, renewal, filing, and what sets the price.

If a claim is made

A claim comes from the party the bond protects, the obligee named on the form, when the duty the bond guarantees is not met.

The surety investigates and pays a valid claim, up to the bond amount. You then repay the surety: a surety bond is a guarantee of your performance, not insurance for you.

Renewal and term

Term and renewal are set in the underwriter's quote.

Keep the bond in force for as long as the obligation behind it runs.

How to file it

Post it with UniSource. Once you accept and pay, the executed bond is issued ready to deliver to UNS Electric or UNS Gas in place of the cash deposit. Wet-ink originals mailed on request.

What sets the price

This bond is underwritten: the premium is quoted from the bond amount and your financial picture, so there is no flat price to show.

One application, one specialist review.

These are the actual fields: your UniSource account number, the deposit amount the utility required, the effective date, and your contact details. A surety specialist reviews it and returns a quote, typically within one business day. Free until your bond is issued.

FAQ

Common questions.

What is a UniSource Energy Services utility deposit bond?It is a surety bond a UNS Electric or UNS Gas customer posts instead of a cash security deposit. Both companies’ Commission-approved tariffs, Sheet 903, Section 3.B.1.c, say a surety bond may be provided as security for the Company in an amount equal to the required deposit. The bond guarantees payment of your utility bills up to that amount.
Who sets the bond amount?UniSource does, when it sets your deposit. Under Sheet 903, Section 3.B.7, a residential deposit cannot exceed two times your estimated average monthly bill and a non-residential deposit cannot exceed two and one-half times your maximum estimated monthly bill. The bond is written for exactly the deposit the utility required — use the figure on your deposit notice.
How much does the bond cost?This bond is quoted on review rather than published at a fixed price. A surety specialist reviews your application and returns the premium, usually within one business day, and you are under no obligation until you accept it.
Will I need collateral?Rarely for a deposit-sized bond. Because the penal sum is capped at a small multiple of your own monthly bill, most files are quoted without collateral. On an unusually large non-residential deposit, the specialist may ask for supporting information or collateral — and tells you before you commit.
Is there a credit check?The bond issues the moment you pay — no credit review of any kind, not even a soft pull. The application asks only for your account, deposit amount, and contact details.
Which A-rated carriers underwrite these bonds?Typically Arch Insurance Company (A.M. Best A+) or Nationwide Mutual Insurance Company (A.M. Best A). Which one writes your bond depends on the bond type and your state. The carrier's name and official signature are printed on the bond you receive.
