utilities; plant construction; colocation

Purpose

Outlines the conditions that allow a utility to construct a new plant
without filing for or receiving a certificate of environmental compatibility
(certificate).

Background

Any utility that plans to construct a
plant, transmission line or both in Arizona must first file an application for
a certificate with the Arizona Corporation Commission (ACC). The application
must be in a form prescribed by the ACC and be accompanied by information with
respect to the proposed type of facilities and description of the site,
including the areas of jurisdiction affected and the estimated cost of the
proposed facilities and site. A utility may not construct a plant or
transmission line within Arizona until it has received a certificate from the
Power Plant and Line Siting Committee with respect to the proposed site,
affirmed and approved by an order of the ACC which must be issued no less than
30 days or more than 60 days after the certificate is issued by the Power Plant
and Line Siting Committee (A.R.S. ��
40-360.03
and
40-360.07
).

A utility
is defined as any person engaged in the generation or
transmission of electric energy. A
plant
is defined as each separate
thermal electric, nuclear or hydroelectric generating unit with a nameplate
rating of 100 megawatts or more for which expenditures or financial commitments
for land acquisition, materials, construction or engineering exceeding $50,000
have not been made before August 13, 1971 (
A.R.S.
� 40-360
).

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

Provisions

1.

Allows a utility, after providing 30 days' written notice to the ACC and
holding at least one public comment session in the county where the relevant
plant is located, to construct a new plant without filing for or receiving a certificate
for the new plant if:

a)

the
new plant is co-located with an extra high load factor customer and the extra
high load factor customer has received all applicable zoning entitlements; and

b)

the utility is a public service corporation or public power entity doing
business in Arizona.

2.

Becomes
effective on the general effective date.
