6. Such exemption shall be granted only upon application by the owner

of the real property on a form prescribed and made available by the

commissioner in cooperation with the authority. The applicant shall

furnish such information as the commissioner shall require. The

application shall be filed with the assessor of the appropriate county,

city, town or village on or before the taxable status date of such

county, city, town or village. A copy of such application shall be filed

with the authority.

7. If the assessor is satisfied that the applicant is entitled to an

exemption pursuant to this section, he or she shall approve the

application and enter the taxable assessed value of the parcel for which

an exemption has been granted pursuant to this section on the assessment

roll with the taxable property, with the amount of the exemption set

forth in a separate column as computed pursuant to subdivision two of

this section in a separate column. In the event that real property

granted an exemption pursuant to this section ceases to be used

primarily for eligible purposes, the exemption granted pursuant to this

section shall cease.

8. (a) Notwithstanding the provisions of subdivision two of this

section, a county, city, town or village may by local law or a school

district, other than a school district to which article fifty-two of the

education law applies, may by resolution provide either (i) that no

exemption under this section shall be applicable within its jurisdiction

with respect to any solar or wind energy system or farm waste energy

system which began construction subsequent to January first, nineteen

hundred ninety-one or the effective date of such local law, ordinance or

resolution, whichever is later, and/or (ii) that no exemption under this

section shall be applicable within its jurisdiction with respect to any

micro-hydroelectric energy system, fuel cell electric generating system,

micro-combined heat and power generating equipment system, electric

energy storage equipment or electric energy storage system, or

fuel-flexible linear generator electric generating system constructed

subsequent to January first, two thousand eighteen or the effective date

of such local law, ordinance or resolution, whichever is later. A copy

of any such local law or resolution shall be filed with the commissioner

and with the president of the authority.

(b) Construction of a solar or wind energy system or a farm waste

energy system shall be deemed to have begun upon the full execution of a

contract or interconnection agreement with a utility; provided however,

that if such contract or interconnection agreement requires a deposit to

be made, then construction shall be deemed to have begun when the

contract or interconnection agreement is fully executed and the deposit

is made. The owner or developer of such a system shall provide written

notification to the appropriate local jurisdiction or jurisdictions upon

execution of the contract or the interconnection agreement.

9. (a) A county, city, town, village or school district, except a

school district under article fifty-two of the education law, that has

not acted to remove the exemption under this section may require the

owner of a property which includes a solar or wind energy system which

meets the requirements of subdivision four of this section, to enter

into a contract for payments in lieu of taxes. Such contract may require

annual payments in an amount not to exceed the amounts which would

otherwise be payable but for the exemption under this section. If the

owner or developer of such a system provides written notification to a

taxing jurisdiction of its intent to construct such a system, then in

order to require the owner or developer of such system to enter into a

contract for payments in lieu of taxes, such taxing jurisdiction must

notify such owner or developer in writing of its intent to require a

contract for payments in lieu of taxes within sixty days of receiving

the written notification. Written notification to a taxing jurisdiction

for this purpose shall include a hard copy letter sent to the

highest-ranking official of the taxing jurisdiction. Such letter shall

explicitly reference subdivision nine of section four hundred

eighty-seven of the real property tax law, and clearly state that,

unless the taxing jurisdiction responds within sixty days in writing

with its intent to require a contract for payments in lieu of taxes,

such project shall not be obligated to make such payments.

(b) Notwithstanding paragraph (a) of this subdivision, should a taxing

jurisdiction adopt a law or resolution at any time within or prior to

the sixty day window, indicating the taxing jurisdiction's ongoing

intent to require a contract for payments in lieu of taxes for such

systems, such law or resolution shall be considered notification to

owners or developers and no further action is required on the part of

the taxing jurisdiction, provided that such law or resolution remains in

effect through the end of the sixty day notification period.

(c) Any payment in lieu of a tax agreement shall not operate for a

period of more than fifteen years, commencing in each instance from the

date on which the benefits of such exemption first become available and

effective.

10. Notwithstanding the foregoing provisions of this section, on or

after April first, two thousand nineteen, a county, city, town or

village may by local law or a school district, other than a school

district to which article fifty-two of the education law applies, may by

resolution provide that real property that comprises or includes a solar

or wind energy system, farm waste energy system, microhydroelectric

energy system, fuel cell electric generating system, microcombined heat

and power generating equipment system, electric energy storage system,

or fuel-flexible linear generator as such terms are defined in

paragraphs (b), (f), (h), (j), (l), (n), and (o) of subdivision one of

this section (hereinafter, individually or collectively, "energy

system"), shall be permanently exempt from any taxation, special ad

valorem levies, and special assessments to the extent provided in

section four hundred ninety of this article, and the owner of such

property shall not be subject to any requirement to enter into a

contract for payments in lieu of taxes in accordance with subdivision

nine of this section, if: (a) the energy system is installed on real

property that is owned or controlled by the state of New York, a

department or agency thereof, or a state authority as that term is

defined by subdivision one of section two of the public authorities law;

and (b) the state of New York, a department or agency thereof, or a

state authority as that term is defined by subdivision one of section

two of the public authorities law has agreed to purchase the energy

produced by such energy system or the environmental credits or

attributes created by virtue of the energy system's operation, in

accordance with a written agreement with the owner or operator of such

energy system. Such exemption shall be granted only upon application by

the owner of the real property on a form prescribed by the commissioner,

which application shall be filed with the assessor of the appropriate

county, city, town or village on or before the taxable status date of

such county, city, town or village.
