New Rules for Approving Power Lines and Plants

This law requires officials in Arizona to check if a proposed power plant or transmission line has confirmed buyers before approving its location.

What This Bill Does

  • Adds the risk of financial failure as a factor when reviewing applications for new power plants or lines.
  • Requires applicants to show they have specific, identified buyers with long-term contracts to purchase electricity.
  • Defines 'known offtakers' as customers who have signed binding agreements to buy future energy output.
  • Exempts public utilities from showing individual buyer contracts because their existing customers count as known buyers.
  • States that projects by public utilities cannot be labeled as speculative under this new rule.

Who It Names or Affects

  • Companies planning to build power plants or transmission lines in Arizona
  • The Power Plant and Transmission Line Siting Committee within the Arizona Corporation Commission
  • Public service corporations and public power entities operating in the state

Terms To Know

Certificate of Environmental Compatibility (CEC)
A permit required before a utility can build a new plant or transmission line.
Known Offtakers
Specific buyers who have signed legally binding, long-term contracts to purchase electricity from the proposed project.
Speculativeness
The level of risk or uncertainty about whether a power plant or line will be financially successful.

Limits and Unknowns

  • The law does not specify an exact date when these new rules take effect.
  • It is unclear how the committee will measure 'financial success' for private companies beyond checking for contracts.
  • The text does not explain what happens if a project has some buyers but not enough to meet the definition of known offtakers.

Amendments

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

Plain English: This amendment adds a new rule requiring officials to check if power plants or transmission lines have confirmed buyers before approving them, while also updating how local laws are handled during the approval process.

  • Officials must now consider whether there are specific, identified buyers with long-term contracts for the electricity a proposed plant or line will produce.
  • The amendment defines 'known offtakers' as buyers who have signed legally binding agreements to purchase a portion of future energy output.
  • It clarifies that if an applicant is already serving customers in Arizona (like a public utility), they do not need these specific contracts because their existing customers count as known buyers.
  • The text updates rules about local laws, requiring officials to notify city or county leaders and let them respond if the state decides those local rules are too restrictive.
  • The amendment uses technical legal terms like 'certificate of environmental compatibility' that may be hard for some readers to understand without more context.
  • It is unclear exactly how much energy must be sold under contract to meet the definition of a 'substantial portion,' as this specific amount was removed from the text.

Plain English: This amendment adds a new rule requiring officials to check if power plants and transmission lines have confirmed buyers before approving them, while also updating definitions for financial risk.

  • Officials must now consider whether there are specific, identified buyers with long-term contracts when deciding on energy projects.
  • The law defines 'known offtakers' as buyers who have signed legally binding agreements to purchase a portion of the project's future electricity output.
  • The amendment clarifies that for public power companies or utilities serving customers in Arizona, their existing customers count as known buyers without needing separate contracts.
  • The text uses technical legal terms like 'speculativeness' and 'certificate of environmental compatibility' which may be hard to fully explain simply.
  • Some parts of the amendment involve removing old definitions that are not clearly explained in this specific document.

Overview

Expands
determining factors for issuing a Certificate of Environmental Compatibility (CEC)
to include the speculativeness of the proposed transmission line or plant as
identified by the existence of known offtakers.

History

Each utility that plans to construct a plant or transmission
line, both defined by statute, in this state must first file an application for
a CEC with the Arizona Corporation Commission which will be referred to the
Chairman of the Power Plant and Transmission Line Siting Committee (Committee).
The Committee may evaluate an application for a CEC and may impose reasonable
conditions on its issuance. The CEC's evaluation must consider certain
conditions including:

1)

existing
plans of this state, local government and private entities for other
developments in the vicinity of the proposed site;

2)

noise
emission levels and interference with communication signals; and

3)

the
total environment of the area (A.R.S. ��
40-360
,
40-360.03

and
40-360.06
).

Provisions

1.

Adds the
speculativeness of the proposed transmission line or plant as identified by the
existence of known offtakers as a factor for considering applications for a CEC
regarding the suitability of a plant or transmission line siting plan. (Sec. 1)

2.

Defines
known
offtakers
as specific, identified buyers:

a.

for a
proposed transmission line, who have contracted to purchase a portion of the
future output of any electrical generating unit that is related to or will be
interconnected with the proposed transmission line; and

b.

for a
proposed plant, who have entered into legally binding, long-term contracts to
purchase a portion of the plant's future output. (Sec. 1)

3.

Defines
speculativeness

as the level of risk or uncertainty that is associated with a proposed
transmission line's or plant's financial success. (Sec. 1)

4.

Makes
technical and conforming changes. (Sec. 1)

5.

States that
an applicant who is a public service corporation or public power entity doing
business in this state:

a.

will
consider the public service corporation's or public power entity's customers as

known offtakers
;

b.

is exempt

Section 1. Section 40-360.06, Arizona Revised
Statutes, is amended to read:

START_STATUTE
40-360.06.

Factors to be considered in issuing a certificate of
environmental compatibility

A. The committee may approve or deny an application
and may impose reasonable conditions on the issuance of a certificate of
environmental compatibility and in so doing shall consider the following
factors as a basis for its action with respect to the suitability of either plant
or transmission line siting plans:

1. Existing plans of this state,
a
local
government and private entities for other developments at or in the vicinity of
the proposed site.

2. Fish, wildlife and plant life and associated
forms of life on which they are dependent.

3. Noise emission levels and interference with
communication signals.

4. The proposed availability of the site to the
public for recreational purposes, consistent with safety considerations and
regulations.

5. Existing scenic areas, historic sites and
structures or archaeological sites at or in the vicinity of the proposed site.

6. The total environment of the area.

7. The technical practicability of achieving a
proposed objective and the previous experience with equipment and methods
available for achieving a proposed objective.

8. The estimated cost of the facilities and site as
proposed by the applicant and the estimated cost of the facilities and site as
recommended by the committee, recognizing that any significant increase in
costs represents a potential increase in the cost of electric energy to the
customers or the applicant.

9. The SPECULATIVENESS of the
proposed transmission line or plant as identified by the existence of known
offtakers.� For the purposes of this paragraph:

(
a
) "Known
offtakers" means
:

(
i
) For a
proposed transmission line, specific, identified buyers that have entered into
legally binding, long-term contracts to purchase a portion of
the future output of any electric generating unit that is related to
or will be interconnected with the proposed transmission line.

(
ii
) For a
proposed plant, specific, identified buyers that have entered into legally
binding, long-term contracts to purchase a portion of the plant's future
output.

(
b
) "Speculativeness"
means the level of risk or uncertainty that is associated with
the proposed transmission line's or plant's financial success.

(
c
) If the
applicant for the proposed transmission line or plant is a public service
corporation or public power entity doing business in this state, the public
service corporation's or public power entity's customers shall serve as the
existence of known offtakers, the identification of specific buyers and legally
binding long-term contracts are not required and the proposed
transmission line or plant may not be deemed speculative.

9.

10.
Any
additional factors that require consideration under applicable federal and
state laws pertaining to any such site.

B. The committee shall give special consideration to
the protection of areas
that are
unique because of
biological wealth or because they are habitats for rare and endangered species.

C. Notwithstanding any other provision of this
article, the committee shall require in all certificates for facilities that
the applicant comply with all applicable nuclear radiation standards and air
and water pollution control standards and regulations
,

but shall not require either of the following:

1. Compliance with performance standards other than
those established by the agency having primary jurisdiction over a particular
pollution source.

2. That a contractor, subcontractor, material
supplier or other person
that is
engaged in the
construction, maintenance, repair or improvement of any project subject to
approval of the commission negotiate, execute or otherwise become a party to
any project labor agreement, neutrality agreement as defined in section 34-321,
apprenticeship program participation or contribution agreement or other
agreement with employees, employees' representatives or any labor organization
as a condition of or a factor in the commission's approval of the project.�
This paragraph does not:

(a) Prohibit private parties from entering into
individual collective bargaining relationships.

(b) Regulate or interfere with activity
that is
protected by law, including the national labor
relations act
.

D. Any certificate
that is

granted by the committee shall be conditioned on compliance by the applicant
with all applicable ordinances, master plans and regulations of
the

this
state, a county or an incorporated city or town,
except that the committee may grant a certificate notwithstanding any such
ordinance, master plan or regulation, exclusive of franchises, if the committee
finds as a fact that compliance with such
an
ordinance,
master plan or regulation is unreasonably restrictive and compliance therewith
is not feasible in view of technology available.
When

If
it becomes apparent to the chairman of the committee
or to the hearing officer that an issue exists with respect to whether such an
ordinance, master plan or regulation is unreasonably restrictive and compliance
therewith is not feasible in view of technology available, the chairman or
hearing officer shall promptly serve notice of such fact by certified mail on
the chief executive officer of the area of jurisdiction affected and,
notwithstanding any provision of this article to the contrary, shall make such
area of jurisdiction a party to the proceedings on its request and shall give
it an opportunity to respond on such issue.
