HB2782: New Rules for Utility Rate Disclosures

This law requires the Arizona Corporation Commission and utility companies to publish specific details about how they calculate costs related to regulatory assets in their rate schedules.

What This Bill Does

  • Requires disclosure of the unamortized balance of a regulatory asset on the date new rates take effect.
  • Mandates reporting the difference between the test year balance and the actual balance when rates start.
  • Demands that utilities state the total amount they expect to recover through amortization expenses over time.
  • Requires explanation of how rate base values are treated if they stay fixed or decline as assets are paid off.
  • Ensures disclosures allow a comparison between amounts recovered in rates and remaining asset balances.

Who It Names or Affects

  • The Arizona Corporation Commission
  • Public service corporations (utility companies)

Limits and Unknowns

  • This law does not force the Commission to use any specific method for adjusting rates.
  • The text states there is no expected cost impact to the state General Fund.

Amendments

These notes stay tied to the official amendment files and metadata from the legislature.

Plain English: This amendment requires public utilities and the Corporation Commission to clearly publish details about how costs for regulatory assets are recovered through customer rates.

  • Utilities must disclose the remaining unpaid balance of a regulatory asset when new rates take effect.
  • The difference between the original cost estimate and the current balance at the time rates start must be shown.
  • Tariff schedules must include a clear plan for how long it will take to recover these costs from customers.
  • Utilities must explain if their rate base value stays fixed or decreases as they collect money from customers.
  • The amendment text uses complex legal formatting that makes some specific definitions of 'fair value' difficult to interpret without the full original bill context.
  • It is unclear exactly which types of assets count as 'regulatory assets' based solely on this amendment text.

Plain English: This amendment requires public utilities and the Corporation Commission to clearly publish details about how costs for regulatory assets are paid back through customer rates.

  • Utilities must disclose the remaining unpaid balance of a regulatory asset when new rates start.
  • The difference between past balances and current balances must be shown in published documents.
  • Tariff schedules must include a clear plan showing how much money will be collected from customers to pay off these costs over time.
  • If assets are treated differently, the utility must explain exactly which rules apply to each type of asset.
  • The amendment text contains many conflicting edits and formatting marks that make some specific legal definitions hard to read clearly.
  • It is unclear if this rule applies immediately or only after a future date because the effective timeline is not stated in the provided text.

H.B. 2782

corporation
commission; utilities; amortization; tariffs

Purpose

Prescribes disclosure requirements for the Arizona Corporation Commission
(ACC) and public service corporations if a regulatory asset is included in rate
base or otherwise reflected in the rates based on a test year or historical
balance.

Background

Under the rules and regulations prescribed by the ACC, every public
service corporation must file with the ACC, and must print and keep open to
public inspection, schedules showing all rates, tolls, rentals, charges and
classifications to be collected or enforced, together with all rules,
regulations, contracts, privileges and facilities which in any manner affect or
relate to rates, tolls, rentals, classifications or service. The ACC may, from
time to time, approve or fix rates, tolls, rentals or charges in excess of or
less than those shown by the schedules. The ACC may also approve or fix rates,
tolls, rentals or charges that do not match with the schedules and prescribe
such changes, by order, in the form of the schedules that demonstrate expediency
(
A.R.S.

� 40-365
).

No change may be made by any public service corporation in any rate,
fare, toll, rental, charge or classification, or in any rule, regulation or
contract relating to or affecting any rate, toll, fare, rental, charge,
classification or service, or in any privilege or facility, except after 30
days' notice to the ACC and to the public. The notice must be given by filing
with the ACC and keeping open for public inspection new schedules stating
plainly the change to be made in the schedules then in force, and the time when
the change will go into effect. The ACC, for good cause shown, may allow
changes without requiring the 30 days' notice by an order specifying the
changes to be made, the time they will take effect and the manner in which they
will be filed and published (
A.R.S.
� 40-367
).

There is no anticipated fiscal impact to the state General Fund
associated with this legislation.

Provisions

1.

Requires
the ACC and a public service corporation, if a regulatory asset is included in
rate base or otherwise reflected in the rates based on a test year or
historical balance, to disclose:

a)

the unamortized balance of the regulatory asset as of the rate effective
date;

b)

the difference between the test year balance and the rate effective date
balance;

c)

the total amount of amortization expense expected to be recovered over
the period the rates are in effect; and

d)

if a
public service corporation's regulatory assets include either assets whose rate
base value remains fixed until the next rate case or assets whose rate base
value declines in proportion to the amortization of the unamortized balance,
the public service corporation must disclose the treatment applied to each
category of regulatory asset and indicate whether and how rate base will be
adjusted over time to reflect declining balances for the assets subject to such
adjustment.

2.

Specifies that nothing in the prescribed disclosure requirements
requires the ACC to adopt any particular adjustment mechanism, but the
prescribed disclosure requirements do require the ACC to ensure that the
disclosures are sufficient to compare the total amounts that will be recovered
in rates against the remaining unamortized balance of regulator asset.

3.

Contains a statement of legislative intent.

4.

Becomes effective on the general effective date.

2. The difference between the test

4. If a public service corporation's

until the next rate case or assets whose rate base value declines in proportion
to the amortization of

the Unamortized balance
, the public service corporation shall disclose the treatment applied
to each category of regulatory asset and indicate whether and how rate base
will be adjusted over time
to reflect declining balances
for the assets subject to such adjustment.

B. Nothing in this section requires
the commission to adopt any particular adjustment mechanism, but this section
does require the commission to ensure that the disclosures required by this
section are sufficient to compare the total amounts that will be recovered in
rates against the remaining unamortized balance
of

END_STATUTE

Sec. 2.
Legislative intent

The legislature intends that the
corporation commission and public
service
corporations publicly post tariff schedules, including amortization schedules,
that impact rates as this provides the public with the ability to comment on
rate schedules that are set by the corporation commission.
