Statutes, is amended to read:

START_STATUTE
41-1519.

Computer data center tax relief; definitions

A.
From and after August 31, 2013,

Tax relief is allowed for the owner or operator of a computer data center
certified pursuant to this section.� The same tax relief is allowed for
qualified colocation tenants of the computer data center. All tax
relief applies during the qualification period.

B. To qualify for the tax relief, the owner or
operator shall submit to the authority an application on a form prescribed by
the authority that includes all of the following:

1. The owner's or operator's name, address and
telephone number.

2. The address of the site where the facility is or
will be located, including, if applicable, information sufficient to identify
the specific portion or portions of the facility composing the computer data
center.

3. If the computer data center is to qualify under
subsection E, paragraph 1 of this section, both of the following:

(a) The anticipated investment associated with the
computer data center for which the tax relief is being sought and whether the
computer data center is anticipated to qualify as a sustainable redevelopment
project.

(b) An affirmation, signed by an authorized
executive representing the owner or operator, that the computer data center is
expected to satisfy one of the certification requirements prescribed in
subsection E, paragraph 1 of this section and that the computer data center
will not violate subsection M of this section.

4. If the computer data center is to qualify under
subsection E, paragraph 2 of this section, an affirmation, signed by an
authorized executive representing the owner or operator, that the computer data
center has satisfied the certification requirements prescribed in subsection E,
paragraph 2 of this section, whether the computer data center qualifies as a
sustainable redevelopment project and that the computer data center will not
violate subsection M of this section.

C. Within sixty days after receiving a complete and
correct application, the authority shall review the application and either
issue a written certification that the computer data center qualifies for the
tax relief or provide written reasons for its denial.� Failure to approve or
deny the application within sixty days after the date the owner or operator
submits the application to the authority constitutes approval of the computer
data center, and the authority shall issue written certification to the owner
or operator within fourteen days. The effective date of the
certification is either the date on which the application was submitted to the
authority or a prospective date stated in the application that does not exceed
five years after the date on which the application was
submitted. The authority shall send a copy of the certification,
including its effective date, to the department of revenue. The authority shall
not certify any new computer data center that submits an application to the
authority after December 31,
2033
2026
.

D. An owner or operator may separate a facility into
one or more computer data centers, which may each receive a separate
certification if each computer data center individually meets the requirements
prescribed in subsection E of this section.� A portion of a facility or an
article of computer data center equipment shall not be deemed to be a part of
more than one computer data center.� The owner or operator may aggregate one or
more of the parcels, buildings, condominiums or modular data centers in a
facility into a single computer data center if, in the aggregate, the parcels,
buildings, condominiums and modular data centers meet the requirements of subsection
E of this section.

E. A computer data center must meet one of the
following requirements after taking into account the combined investments made
by the owner, operator or qualified colocation tenants of a computer data
center:

1. On or before the fifth anniversary of
certification, the computer data center creates a minimum investment of at
least:

(a) $25,000,000 of new investment, including costs
of land, buildings, improvements, modular data centers and computer data center
equipment, whether owned or leased or paid for pursuant to a right to use
agreement, if the computer data center is located in a county with a population
of eight hundred thousand or less persons.

(b) $50,000,000 of new investment, including costs
of land, buildings, improvements, modular data centers and computer data center
equipment, whether owned or leased or paid for pursuant to a right to use
agreement, if the computer data center is located in a county with a population
of more than eight hundred thousand persons.

2. During the seventy-two months immediately
before September 1, 2013, the computer data center created an investment of at
least $250,000,000, including costs of land, buildings, improvements,
modular data centers and computer data center equipment, whether owned or leased
or paid for pursuant to a right to use agreement.

F. On or before the fifth anniversary of the
certification of a new computer data center, the owner or operator shall notify
the authority in writing that the computer data center for which the
certification is requested has or has not satisfied the requirements prescribed
in subsection E, paragraph 1 of this section. Until a new computer
data center satisfies the requirements prescribed in subsection E, paragraph 1
of this section, the owner or operator shall keep detailed records of all
investment created by the new computer data center, including costs of land,
buildings, improvements, modular data centers and computer data center
equipment, and all tax relief directly received by the owner or
operator. This subsection does not apply to an existing computer
data center.

G. If the authority determines that:

1. A new computer data center that is certified
under subsection E, paragraph 1 of this section has not complied with the
requirements and time periods prescribed by subsection E, paragraph 1 of this
section, the authority shall revoke the computer data center's
certification. If the certification is revoked, the qualification
period of any owner, operator or qualified colocation tenant of the computer
data center automatically terminates, and the department of revenue may
recapture all or part of the tax relief provided directly to the owners and
operators.� A qualified colocation tenant is not subject to recapture of any
part of tax relief received pursuant to this section, except that a
contributing qualified colocation tenant may be subject to recapture if it is
located in a computer data center that is certified from and after August 31,
2016.� An owner or operator may appeal any revocation under this paragraph
pursuant to chapter 6, article 10 of this title.

2. There has been a violation of subsection M of
this section with respect to a computer data center:

(a) The authority shall revoke the computer data
center's certification and, if revoked, the qualification period of any owner,
operator or qualified colocation tenant of the computer data center
automatically terminates.

(b) The department of revenue may not recapture any
tax relief provided directly to the owner, operator or qualified colocation
tenant before the date of revocation.

(c) An owner or operator may appeal any revocation
under this paragraph pursuant to chapter 6, article 10 of this title.

H. The authority and the department of revenue shall
adopt rules and prescribe forms and procedures as necessary for the purposes of
this section. The authority and the department shall collaborate in adopting
rules as necessary to avoid duplication and inconsistencies while accomplishing
the purposes of this section.� The authority has exclusive authority over
issues related to certification, including determinations as to whether a
computer data center has satisfied the requirements of subsection E of this
section, constitutes a qualified sustainable redevelopment project or has
committed a violation of this section.� The department of revenue has exclusive
authority over the administration of tax relief.

I. Proprietary business information contained in the
application described in subsection B of this section, the written notice
described in subsection F of this section and the list described in subsection
J of this section are confidential and shall not be disclosed to the public
except that the information shall be transmitted to the department of revenue.�
The authority or the department may disclose the name of a computer data center
that has been certified pursuant to this section.

J. The owner or operator shall provide the authority
and the department of revenue with a list of qualified colocation tenants,
including the commencement and expiration dates of each qualified colocation
tenant's agreement to use or occupy all or part of the computer data center,
and shall notify the authority and the department of any changes within thirty
days. The failure of an owner or operator to provide the list or
notify the authority and department of revenue of changes within the required
time is not grounds for termination of the computer data center's
certification, but may preclude unlisted colocation tenants from receiving tax
relief until the list is provided or updated.

K. Except as provided in subsection G of this
section, if a computer data center has been certified, the certification
remains in effect, even in the event of a future transfer, sale or disposition,
directly or indirectly, of the computer data center.

L. For the purposes of qualifying and continuing as
a sustainable redevelopment project:

1. After receiving certification, an owner may
substantially demolish all or part of an existing building to the extent
reasonably necessary to accommodate future computer data center use, and the
demolition is not cause for loss of certification as a sustainable
redevelopment project. An existing building that has been
substantially demolished before certification is not eligible to qualify as a
sustainable redevelopment project.�

2. An owner or operator may expand the boundaries of
a certified computer data center by increasing the size of an existing building
within a sustainable redevelopment project or by building additional
improvements in an unlimited manner to the extent the expansion is constructed
on the same parcel of land on which the original sustainable redevelopment
project is located or on a contiguous parcel, regardless of whether the
contiguous parcel was within the original description of the boundaries of the
certified computer data center.� Expansion activities do not prevent a facility
from maintaining its classification as a sustainable redevelopment project.

3. All construction activities and investments
related to demolition and expansion activities described in this subsection are
considered to be a part of the sustainable redevelopment project.

M. This section does not allow a computer data
center to do either of the following:

1. Generate electricity for resale purposes.

2. Generate, provide or sell electricity outside of
the computer data center.

N. The owner or operator may be a single individual
or entity or multiple affiliated entities.

Sec. 2. Section 41-1520, Arizona Revised
Statutes, is amended to read:

START_STATUTE
41-1520.

International operations centers; utility relief; certification;
revocation; definitions

A. Utility relief is allowed for the owner or
operator of an international operations center that is certified pursuant to
this section.

B. To qualify for the utility relief, the owner or
operator must submit to the authority an application in a form prescribed by
the authority that includes all of the following:

1. The owner's or operator's name, address and
telephone number.

2. The address of the site where the facility is or
will be located, including, if applicable, information sufficient to identify
the specific portion or portions of the facility comprising the international
operations center.

3. An estimate of the total investment the owner or
operator or an affiliated entity, including investments made by a third-party
entity on behalf of and for the benefit of the owner, operator or affiliated
entity, will make, over a three-year period beginning on the date the
application is received, in new renewable energy facilities in this state that
produce energy for self-consumption by the international operations
center using renewable energy resources.

4. The expected location of each of the renewable
energy facilities that comprise the total investment estimated in paragraph 3
of this subsection and the earliest date that each facility is expected to be
operational.

5. A statement that a portion of the power generated
by each renewable energy facility, as required by subsection D, paragraph 4 of
this section, is for self-consumption and will be used for international
operations center use.

C. Within sixty days after receiving a complete and
correct application, the authority shall review the application and either
issue a written certification that the international operations center
qualifies for the utility relief or provide written reasons for its
denial. A failure to approve or deny the application within sixty
days after the date of submittal constitutes certification of the international
operations center, and the authority shall issue written certification to the
owner or operator within fourteen days. The authority shall send a
copy of the certification to the department of revenue.
The
authority shall not certify any new international operations center that
submits an application to the authority after December 31, 2026.

D. The owner or operator of the international
operations center must achieve all of the following requirements after taking
into account the combined investments made by the owner or operator:

1. A minimum annual investment of $100,000,000 in
new capital assets, including costs of land, buildings and international
operations center equipment in each of ten consecutive taxable years of the
owner or operator. Investments greater than $100,000,000 in any taxable year
may be carried forward as a credit toward the investment requirement in future
years.

2. On or before the tenth anniversary of
certification, a minimum investment of at least $1,250,000,000 in new capital
assets, including costs of land, buildings and international operations center
equipment.

3. An investment by the owner or operator or an
affiliated entity, or a third-party entity on behalf of or for the direct
benefit of the owner, operator or affiliated entity, of at least $100,000,000
in one or more new renewable energy facilities in this state that produce
energy for self-consumption using renewable energy
resources. The minimum investment must be completed within a
three-year period beginning on the date the initial application is received or
by December 31, 2030, whichever is earlier. Construction of the
renewable energy facilities shall begin not later than six months after the
receipt of the application.

4. The use of a portion of the energy produced at
each renewable energy facility for self-consumption in this
state. By the fifth year a renewable energy facility is in
operation, at least fifty-one percent of the energy produced must be used for
self-consumption in this state.� Self-consumption includes the
power used by related entities if the related entities are directly or
indirectly under the same ownership interests that collectively own more than
eighty percent. Power that a renewable energy facility transfers to
a utility qualifies as self-consumption if the utility is the same
utility that provides power to the owner's or operator's international
operations center in this state, regardless of whether the owner or operator or
an affiliated entity owns or leases the renewable energy facility or the land
on which it is located at the time of transfer.

5. The use of power for self-consumption under
paragraph 4 of this subsection is for an international operations center in
this state. A lessor of an international operations center facility
that uses power for self-consumption under paragraph 4 of this subsection
satisfies the requirements of this paragraph if the lessee is an international
operations center and the power is transferred as part of the lease to the
lessee.

E. Within thirty days after the end of each taxable
year following certification, and within thirty days after the tenth
anniversary of certification, the owner or operator shall furnish the authority
written information demonstrating whether the certified international
operations center has or has not satisfied the requirements prescribed in
subsection D of this section. Until the requirements prescribed in
subsection D of this section are met, the owner or operator shall keep detailed
records of all capital investment in the international operations center,
including costs of land, buildings and international operations center
equipment, and all utility relief directly received by the owner or operator.

F. If the authority determines that the requirements
of this section have not been satisfied, the authority may revoke the
certification of the international operations center and notify the department
of revenue in writing. The owner or operator may appeal the
revocation. The authority may give special consideration or allow a
temporary exception if there is extraordinary hardship due to factors beyond
the owner's or operator's control. If certification is revoked, the
department of revenue shall order the owner or operator to forfeit further
entitlement to utility relief. If the owner or operator fails to
make a minimum capital investment of $100,000,000 in a taxable year, taking
into account any excess investment amounts carried forward from previous years,
the owner or operator may avoid revocation of its certification by paying to
the department of revenue within sixty days after the end of the taxable year
the amount of the utility relief provided pursuant to this section in that year.

G. Each year after initial certification, on or
before the anniversary date of the application specified in subsection B of
this section, the owner, operator or affiliated entity must submit to the
authority:

1. Documentation of the owner's, operator's or
affiliated entity's progress toward the investment required by subsection D,
paragraph 3 of this section. This documentation is not required
after the authority receives a report stating that the required investment
threshold has been reached.

2. Documentation for each renewable energy facility
that demonstrates that the required portion of the power generated by each
facility is for self-consumption as required by subsection D, paragraph 4
of this section.

H. The authority and the department of revenue shall
prescribe forms and procedures as necessary for the purposes of this section.

I. Proprietary business information contained in the
application form described in subsection B of this section and the written
notice described in subsection F of this section are confidential and may not
be disclosed to the public, except that the information shall be transmitted to
the department of revenue. The authority or the department of
revenue may disclose the name of an international operations center that has
been certified pursuant to this section.

J. Except as provided in subsection F of this
section, on certification, the international operations center remains
certified unless ownership of the international operations center is sold,
conveyed, transferred or otherwise directly or indirectly disposed of to
another entity in which the original owner holds less than a controlling
interest.� For the purposes of this subsection, "controlling
interest" means at least eighty percent of the voting shares of a
corporation or of the interests in a noncorporate entity.

K. An owner or operator may be composed of a single
entity or affiliated entities.

L. If the information required by subsection B,
paragraphs 3, 4 and 5 of this section and the documentation required by
subsection G of this section were already provided to the department of revenue
for the purposes of the credit provided by section 43-1164.05, the owner
or operator is not required to provide the information or documentation a
second time under this section.

M. For the purposes of this section:

1. "Affiliated entity" means any of the
following:

(a) An entity that is included in the same Arizona
income tax return as the owner or operator of the international operations
center.

(b) Any entity in which the owner or operator of the
international operations center is entitled to a distributive share of the
entity's income or loss.

(c) Any entity, including a single-member
limited liability company, that is disregarded for federal income tax purposes
