Requirements.

1.8 Reactive Power and Primary Frequency Response

1.8.1 Power Factor Design Criteria

1.8.1.1 Synchronous Generation. The Interconnection Customer shall design its
Small Generating Facility to maintain a composite power delivery at continuous
rated power output at the Point of Interconnection at a power factor within the
range of 0.95 leading to 0.95 lagging, unless the NYISO or the Transmission
Owner in whose Transmission District the Small Generating Facility interconnects has established different requirements that apply to all similarly
situated generators in the New York Control Area or Transmission District (as
applicable) on a comparable basis, in accordance with Good Utility Practice.

1.8.1.2 Non-Synchronous Generation. The Interconnection Customer shall
design its Small Generating Facility to maintain a composite power delivery at
continuous rated power output at the high-side of the generator substation at a
power factor within the range of 0.95 leading to 0.95 lagging, unless the NYISO
or the Transmission Owner in whose Transmission District the Small Generating
Facility interconnects has established a different power factor range that applies to
all similarly situated non-synchronous generators in the New York Control Area
or Transmission District (as applicable) on a comparable basis, in accordance with
Good Utility Practice. This power factor range standard shall be dynamic and can
be met using, for example, power electronics designed to supply this level of
reactive capability (taking into account any limitations due to voltage level, real
power output, etc.) or fixed and switched capacitors, or a combination of the two.
This requirement shall only apply to newly interconnecting non-synchronous
generators that have not yet executed a Facilities Study Agreement as of
September 21, 2016.

1.8.2 The NYISO is required to pay the Interconnection Customer for reactive power,
or voltage support service, that the Interconnection Customer provides from the

SERVICE AGREEMENT NO. 2975

Small Generating Facility in accordance with Rate Schedule 2 of the NYISO
Services Tariff.

1.8.3 Primary Frequency Response. Interconnection Customer shall ensure the primary
frequency response capability of its Small Generating Facility by installing,
maintaining, and operating a functioning governor or equivalent controls. The
term “functioning governor or equivalent controls” as used herein shall mean the
required hardware and/or software that provides frequency responsive real power
control with the ability to sense changes in system frequency and autonomously
adjust the Small Generating Facility’s real power output in accordance with the
droop and deadband parameters and in the direction needed to correct frequency
deviations. Interconnection Customer is required to install a governor or
equivalent controls with the capability of operating: (1) with a maximum 5
percent droop and ±0.036 Hz deadband; or (2) in accordance with the relevant
droop, deadband, and timely and sustained response settings from an approved
Applicable Reliability Standard providing for equivalent or more stringent
parameters. The droop characteristic shall be: (1) based on the nameplate
capacity of the Small Generating Facility, and shall be linear in the range of
frequencies between 59 to 61 Hz that are outside of the deadband parameter; or
(2) based on an approved Applicable Reliability Standard providing for an
equivalent or more stringent parameter. The deadband parameter shall be: the
range of frequencies above and below nominal (60 Hz) in which the governor or
equivalent controls is not expected to adjust the Small Generating Facility’s real
power output in response to frequency deviations. The deadband shall be
implemented: (1) without a step to the droop curve, that is, once the frequency
deviation exceeds the deadband parameter, the expected change in the Small
Generating Facility’s real power output in response to frequency deviations shall
start from zero and then increase (for under-frequency deviations) or decrease (for
over-frequency deviations) linearly in proportion to the magnitude of the
frequency deviation; or (2) in accordance with an approved Applicable Reliability
Standard providing for an equivalent or more stringent parameter.

Interconnection Customer shall notify NYISO that the primary frequency
response capability of the Small Generating Facility has been tested and
confirmed during commissioning. Once Interconnection Customer has
synchronized the Small Generating Facility with the New York State
Transmission System, Interconnection Customer shall operate the Small
Generating Facility consistent with the provisions specified in Articles 1.8.3.1 and

1.8.3.2 of this Agreement. The primary frequency response requirements
contained herein shall apply to both synchronous and non-synchronous Small
Generating Facilities.

1.8.3.1 Governor or Equivalent Controls. Whenever the Small Generating Facility
is operated in parallel with the New York State Transmission System,
Interconnection Customer shall operate the Small Generating Facility with its
governor or equivalent controls in service and responsive to frequency.
Interconnection Customer shall: (1) in coordination with NYISO, set the
deadband parameter to: (1) a maximum of ±0.036 Hz and set the droop parameter

SERVICE AGREEMENT NO. 2975

to a maximum of 5 percent; or (2) implement the relevant droop and deadband
settings from an approved Applicable Reliability Standard that provides for
equivalent or more stringent parameters. Interconnection Customer shall be
required to provide the status and settings of the governor and equivalent controls
to NYISO and/or the Connecting Transmission Owner upon request. If
Interconnection Customer needs to operate the Small Generating Facility with its
governor or equivalent controls not in service, Interconnection Customer shall
immediately notify NYISO and the Connecting Transmission Owner, and provide
both with the following information: (1) the operating status of the governor or
equivalent controls (i.e., whether it is currently out of service or when it will be
taken out of service); (2) the reasons for removing the governor or equivalent
controls from service; and (3) a reasonable estimate of when the governor or
equivalent controls will be returned to service. Interconnection Customer shall
make Reasonable Efforts to return its governor or equivalent controls into service
as soon as practicable. Interconnection Customer shall make Reasonable Efforts
to keep outages of the Small Generating Facility’s governor or equivalent controls
to a minimum whenever the Small Generating Facility is operated in parallel with
the New York State Transmission System.

1.8.3.2 Timely and Sustained Response. Interconnection Customer shall ensure
that the Small Generating Facility’s real power response to sustained frequency
deviations outside of the deadband setting is automatically provided and shall
begin immediately after frequency deviates outside of the deadband, and to the
extent the Small Generating Facility has operating capability in the direction
needed to correct the frequency deviation. Interconnection Customer shall not
block or otherwise inhibit the ability of the governor or equivalent controls to
respond and shall ensure that the response is not inhibited, except under certain
operational constraints including, but not limited to, ambient temperature
limitations, physical energy limitations, outages of mechanical equipment, or
regulatory requirements. The Small Generating Facility shall sustain the real
power response at least until system frequency returns to a value within the
deadband setting of the governor or equivalent controls. An Applicable
Reliability Standard with equivalent or more stringent requirements shall
supersede the above requirements.

1.8.3.3 Exemptions. Small Generating Facilities that are regulated by the United
States Nuclear Regulatory Commission shall be exempt from Articles 1.8.3,

1.8.3.1, and 1.8.3.2 of this Agreement. Small Generating Facilities that are
behind the meter generation that is sized-to-load (i.e., the thermal load and the
generation are near-balanced in real-time operation and the generation is primarily
controlled to maintain the unique thermal, chemical, or mechanical output
necessary for the operating requirements of its host facility) shall be required to
install primary frequency response capability requirements in accordance with the
droop and deadband capability requirements specified in Article 1.8.3, but shall
be otherwise exempt from the operating requirements in Articles 1.8.3, 1.8.3.1,

1.8.3.2, and 1.8.3.4 of this Agreement.

SERVICE AGREEMENT NO. 2975

1.8.3.4 Electric Storage Resources. Interconnection Customer interconnecting an
electric storage resource shall establish an operating range in Attachment 5 of its
SGIA that specifies a minimum state of charge and a maximum state of charge
between which the electric storage resource will be required to provide primary
frequency response consistent with the conditions set forth in Articles 1.8.3,

1.8.3.1, 1.8.3.2, and 1.8.3.3 of this Agreement. Attachment 5 shall specify
whether the operating range is static or dynamic, and shall consider (1) the
expected magnitude of frequency deviations in the interconnection; (2) the
expected duration that system frequency will remain outside of the deadband
parameter in the interconnection; (3) the expected incidence of frequency
deviations outside of the deadband parameter in the interconnection; (4) the
physical capabilities of the electric storage resource; (5) operational limitations of
the electric storage resources due to manufacturer specification; and (6) any other
relevant factors agreed to by the NYISO, Connecting Transmission Owner, and
Interconnection Customer. If the operating range is dynamic, then Attachment 5
must establish how frequently the operating range will be reevaluated and the
factors that may be considered during its reevaluation.

Interconnection Customer’s electric storage resource is required to provide timely
and sustained primary frequency response consistent with Article 1.8.3.2 of this
Agreement when it is online and dispatched to inject electricity to the New York
State Transmission System and/or receive electricity from the New York State
Transmission System. This excludes circumstances when the electric storage
resource is not dispatched to inject electricity to the New York State Transmission
System and/or dispatched to receive electricity from the New York State
Transmission System. If Interconnection Customer’s electric storage resource is
charging at the time of a frequency deviation outside of its deadband parameter, it
is to increase (for over-frequency deviations) or decrease (for under-frequency
deviations) the rate at which it is charging in accordance with its droop parameter.
Interconnection Customer’s electric storage resource is not required to change
from charging to discharging, or vice versa, unless the response necessitated by
the droop and deadband settings requires it to do so and it is technically capable
of making such a transition.

1.9 Capitalized Terms

Capitalized terms used herein shall have the meanings specified in the Glossary of Terms
in Attachment 1 or the body of this Agreement. Capitalized terms used herein that are not so
defined shall have the meanings specified in Appendix 1 of Attachment Z, Section 25.1.2 of
Attachment S, or Section 30.1 of Attachment X of the ISO OATT.

of this Agreement shall be determined in accordance with Attachment S of the
ISO OATT, as required by Section 32.3.5.3.2 of Attachment Z. The
Interconnection Customer shall be responsible for all System Upgrade Facility
costs as required by Section 32.3.5.3.2 of Attachment Z or its share of any System
Upgrade Facilities and System Deliverability Upgrades costs resulting from the
final Attachment S process, as applicable, and Attachment 6 to this Agreement
shall be revised accordingly.

5.2.2 Pending the outcome of the Attachment S cost allocation process, if applicable,
the Interconnection Customer may elect to proceed with the interconnection of its
Small Generating Facility in accordance with Section 32.3.5.3 of the SGIP.

5.3 Special Provisions for Affected Systems

For the repayment of amounts advanced to the Affected System Operator for System
Upgrade Facilities or System Deliverability Upgrades, the Interconnection Customer and
Affected System Operator shall enter into an agreement that provides for such repayment, but
only if responsibility for the cost of such System Upgrade Facilities is not to be allocated in
accordance with Attachment S of the ISO OATT. The agreement shall specify the terms
governing payments to be made by the Interconnection Customer to the Affected System
Operator as well as the repayment by the Affected System Operator.

SERVICE AGREEMENT NO. 2975

Article 6 Billing, Payment, Milestones, and Financial Security

6.1 Billing and Payment Procedures and Final Accounting

6.1.1 The Connecting Transmission Owner shall bill the Interconnection Customer for
the design, engineering, construction, and procurement costs of Interconnection
Facilities and Upgrades contemplated by this Agreement on a monthly basis, or as
otherwise agreed by those Parties. The Interconnection Customer shall pay all
invoice amounts within thirty (30) calendar days after receipt of the invoice.

6.1.2 Within three months of completing the construction and installation of the
Connecting Transmission Owner’s Interconnection Facilities and/or Upgrades
described in the Attachments to this Agreement, the Connecting Transmission
Owner shall provide the Interconnection Customer with a final accounting report
of any difference between (1) the Interconnection Customer’s cost responsibility
for the actual cost of such facilities or Upgrades, and (2) the Interconnection
Customer’s previous aggregate payments to the Connecting Transmission Owner
for such facilities or Upgrades. If the Interconnection Customer’s cost
responsibility exceeds its previous aggregate payments, the Connecting
Transmission Owner shall invoice the Interconnection Customer for the amount
due and the Interconnection Customer shall make payment to the Connecting
Transmission Owner within thirty (30) calendar days. If the Interconnection
Customer’s previous aggregate payments exceed its cost responsibility under this
Agreement, the Connecting Transmission Owner shall refund to the

Interconnection Customer an amount equal to the difference within thirty (30)
calendar days of the final accounting report.

6.1.3 If the Interconnection Customer disputes an amount to be paid, the
Interconnection Customer shall pay the disputed amount to the Connecting
Transmission Owner or into an interest bearing escrow account, pending
resolution of the dispute in accordance with Article 10 of this Agreement. To the
extent the dispute is resolved in the Interconnection Customer’s favor, that portion
of the disputed amount will be credited or returned to the Interconnection
Customer with interest at rates applicable to refunds under the Commission’s
regulations. To the extent the dispute is resolved in the Connecting Transmission
Owner’s favor, that portion of any escrowed funds and interest will be released to
the Connecting Transmission Owner.

6.2 Milestones

Subject to the provisions of the SGIP, the Parties shall agree on milestones for which
each Party is responsible and list them in Attachment 4 of this Agreement. A Party’s obligations
under this provision may be extended by agreement. If a Party anticipates that it will be unable
to meet a milestone for any reason other than a Force Majeure event, it shall immediately notify
the other Parties of the reason(s) for not meeting the milestone and: (1) propose the earliest
reasonable alternate date by which it can attain this and future milestones, and (2) requesting
appropriate amendments to Attachment 4. The Party affected by the failure to meet a milestone

SERVICE AGREEMENT NO. 2975

shall not unreasonably withhold agreement to such an amendment unless: (1) it will suffer
significant uncompensated economic or operational harm from the delay, (2) attainment of the
same milestone has previously been delayed, or (3) it has reason to believe that the delay in
meeting the milestone is intentional or unwarranted notwithstanding the circumstances explained
by the Party proposing the amendment.

6.3 Financial Security Arrangements

At least twenty (20) Business Days prior to the commencement of the design,
procurement, installation, or construction of a discrete portion of the Connecting Transmission
Owner’s Interconnection Facilities, the Interconnection Customer shall provide the Connecting
Transmission Owner, at the Interconnection Customer’s option, a guarantee, a surety bond, letter
of credit or other form of security that is reasonably acceptable to the Connecting Transmission
Owner and is consistent with the Uniform Commercial Code of the jurisdiction where the Point
of Interconnection is located. Such security for payment shall be in an amount sufficient to
cover the costs for constructing, designing, procuring, and installing the applicable portion of the
Connecting Transmission Owner’s Interconnection Facilities and shall be reduced on a dollar-
for-dollar basis for payments made to the Connecting Transmission Owner under this Agreement
during its term. The Connecting Transmission Owner may draw on any such security to the
extent that the Interconnection Customer fails to make any payments due under this Agreement.
In addition:

6.3.1 The guarantee must be made by an entity that meets the creditworthiness
requirements of the Connecting Transmission Owner, and contain terms and
conditions that guarantee payment of any amount that may be due from the
Interconnection Customer, up to an agreed-to maximum amount.

6.3.2 The letter of credit or surety bond must be issued by a financial institution or
insurer reasonably acceptable to the Connecting Transmission Owner and must
specify a reasonable expiration date.

6.3.3 Attachment Z to the ISO OATT shall govern the security that an Interconnection
Customer provides for System Upgrade Facilities identified through

Interconnection Studies under the Small Generator Interconnection Procedures.

6.3.4 Notwithstanding the above, Security posted for System Upgrade Facilities for a
Small Generating Facility required to enter the Class Year process, or cash or
Security provided for System Deliverability Upgrades, shall meet the

requirements for Security contained in Attachment S to the ISO OATT.

SERVICE AGREEMENT NO. 2975

Article 7 Assignment, Liability, Indemnity, Force Majeure, Consequential Damages,
and Default

7.1 Assignment

This Agreement, and each and every term and condition hereof, shall be binding upon
and inure to the benefit of the Parties hereto and their respective successors and assigns. This
Agreement may be assigned by any Party upon fifteen (15) Business Days prior written notice
and opportunity to object by the other Parties; provided that:

7.1.1 A Party may assign this Agreement without the consent of the other Parties to any
affiliate of the assigning Party with an equal or greater credit rating and with the
legal authority and operational ability to satisfy the obligations of the assigning
Party under this Agreement, provided that the Interconnection Customer promptly
notifies the NYISO and the Connecting Transmission Owner of any such
assignment. A Party may assign this Agreement without the consent of the other
Parties in connection with the sale, merger, restructuring, or transfer of a
substantial portion of all of its assets, including the Interconnection Facilities it
owns, so long as the assignee in such a transaction directly assumes all rights,
duties and obligation arising under this Agreement.

7.1.2 The Interconnection Customer shall have the right to assign this Agreement,
without the consent of the NYISO or Connecting Transmission Owner, for
collateral security purposes to aid in providing financing for the Small Generating
Facility.

7.1.3 Any attempted assignment that violates this article is void and ineffective.
Assignment shall not relieve a Party of its obligations, nor shall a Party’s
obligations be enlarged, in whole or in part, by reason thereof. An assignee is
responsible for meeting the same financial, credit, and insurance obligations as
the Interconnection Customer. Where required, consent to assignment will not be
unreasonably withheld, conditioned or delayed.

7.2 Limitation of Liability

Each Party’s liability to the other Parties for any loss, cost, claim, injury, liability, or
expense, including reasonable attorney’s fees, relating to or arising from any act or omission in
its performance of this Agreement, shall be limited to the amount of direct damage actually
incurred. In no event shall any Party be liable to the other Parties for any indirect, special,
consequential, or punitive damages.

7.3 Indemnity

7.3.1 This provision protects each Party from liability incurred to third parties as a
result of carrying out the provisions of this Agreement. Liability under this
provision is exempt from the general limitations on liability found in article 7.2.

SERVICE AGREEMENT NO. 2975

7.3.2 Each Party (the “Indemnifying Party”) shall at all times indemnify, defend, and
hold harmless the other Parties (each an “ Indemnified Party”) from, any and all
damages, losses, claims, including claims and actions relating to injury to or death
of any person or damage to property, the alleged violation of any Environmental
Law, or the release or threatened release of any Hazardous Substance, demand,
suits, recoveries, costs and expenses, court costs, attorney fees, and all other
obligations by or to third parties (any and all of these a “Loss”), arising out of or
resulting from: (i) the Indemnified Party’s performance under this Agreement on
behalf of the Indemnifying Party, except in cases where the Indemnifying Party
can demonstrate that the Loss of the Indemnified Party was caused by the gross
negligence or intentional wrongdoing by the Indemnified Party, or (ii) the
violation by the Indemnifying Party of any Environmental Law or the release by
the Indemnifying Party of a Hazardous Substance.

7.3.3 If a Party is entitled to indemnification under this article as a result of a claim by a
third party, and the Indemnifying Party fails, after notice and reasonable
opportunity to proceed under this article, to assume the defense of such claim,
such Indemnified Party may at the expense of the Indemnifying Party contest,
settle or consent to the entry of any judgment with respect to, or pay in full, such
claim.

7.3.4 If an Indemnifying Party is obligated to indemnify and hold any Indemnified
Party harmless under this article, the amount owing to the Indemnified Party shall
be the amount of such Indemnified Party’s actual loss, net of any insurance or
other recovery.

7.3.5 Promptly after receipt by an Indemnified Party of any claim or notice of the
commencement of any action or administrative or legal proceeding or

investigation as to which the indemnity provided for in this article may apply, the
Indemnified Party shall notify the Indemnifying Party of such fact. Any failure of
or delay in such notification shall not affect a Party’s indemnification obligation
unless such failure or delay is materially prejudicial to the Indemnifying Party.

7.4 Consequential Damages

Other than as expressly provided for in this Agreement, no Party shall be liable under any
provision of this Agreement for any losses, damages, costs or expenses for any special, indirect,
incidental, consequential, or punitive damages, including but not limited to loss of profit or
revenue, loss of the use of equipment, cost of capital, cost of temporary equipment or services,
whether based in whole or in part in contract, in tort, including negligence, strict liability, or any
other theory of liability; provided, however, that damages for which a Party may be liable to
another Party under another agreement will not be considered to be special, indirect, incidental,
or consequential damages hereunder.

SERVICE AGREEMENT NO. 2975

7.5 Force Majeure

7.5.1 As used in this article, a “Force Majeure Event” shall mean “any act of God, labor
disturbance, act of the public enemy, war, insurrection, riot, fire, storm or flood,
explosion, breakage or accident to machinery or equipment, any order, regulation
or restriction imposed by governmental, military or lawfully established civilian
authorities, or any other cause beyond a Party’s control. A Force Majeure Event
does not include an act of negligence or intentional wrongdoing.” For the
purposes of this article, this definition of Force Majeure shall supersede the
definitions of Force Majeure set out in Section 32.10.1 of the ISO OATT.

7.5.2 If a Force Majeure Event prevents a Party from fulfilling any obligations under
this Agreement, the Party affected by the Force Majeure Event (“Affected Party”)
shall promptly notify the other Parties, either in writing or via the telephone, of
the existence of the Force Majeure Event. The notification must specify in
reasonable detail the circumstances of the Force Majeure Event, its expected
duration, and the steps that the Affected Party is taking to mitigate the effects of
the event on its performance. The Affected Party shall keep the other Parties
informed on a continuing basis of developments relating to the Force Majeure
Event until the event ends. The Affected Party will be entitled to suspend or
modify its performance of obligations under this Agreement (other than the
obligation to make payments) only to the extent that the effect of the Force
Majeure Event cannot be mitigated by the use of Reasonable Efforts. The
Affected Party will use Reasonable Efforts to resume its performance as soon as
possible.

7.6 Breach and Default

7.6.1 No Breach of this Agreement shall exist where such failure to discharge an
obligation (other than the payment of money) is the result of a Force Majeure
Event or the result of an act or omission of the other Parties. Upon a Breach, the
non-breaching Party shall give written notice of such Breach to the Breaching
Party. Except as provided in article 7.6.2, the Breaching Party shall have sixty
(60) calendar days from receipt of the Breach notice within which to cure such
Breach; provided however, if such Breach is not capable of cure within sixty (60)
calendar days, the Breaching Party shall commence such cure within twenty (20)
calendar days after notice and continuously and diligently complete such cure
within six months from receipt of the Breach notice; and, if cured within such
time, the Breach specified in such notice shall cease to exist.

7.6.2 If a Breach is not cured as provided in this article, or if a Breach is not capable of
being cured within the period provided for herein, a Default shall exist and the
non-defaulting Parties acting together shall thereafter have the right to terminate
this Agreement, in accordance with article 3.3 hereof, by written notice to the
defaulting Party at any time until cure occurs, and be relieved of any further
obligation hereunder and, whether or not those Parties terminate this Agreement,
to recover from the defaulting Party all amounts due hereunder, plus all other

SERVICE AGREEMENT NO. 2975

damages and remedies to which they are entitled at law or in equity. The
provisions of this article shall survive termination of this Agreement.

7.6.3 In cases where the Interconnection Customer has elected to proceed under
Section 32.3.5.3 of the SGIP, if the Interconnection Request is withdrawn or
deemed withdrawn pursuant to the SGIP during the term of this Agreement, this
Agreement shall terminate.

SERVICE AGREEMENT NO. 2975

Article 8 Insurance

8.1 The Interconnection Customer shall, at its own expense, maintain in force general
liability insurance without any exclusion for liabilities related to the interconnection
undertaken pursuant to this Agreement. The amount of such insurance shall be sufficient
to insure against all reasonably foreseeable direct liabilities given the size and nature of
the generating equipment being interconnected, the interconnection itself, and the
characteristics of the system to which the interconnection is made. Such insurance
coverage is specified in Attachment 7 to this Agreement. The Interconnection Customer
shall obtain additional insurance only if necessary as a function of owning and operating
a generating facility. Such insurance shall be obtained from an insurance provider
authorized to do business in New York State where the interconnection is located.
Certification that such insurance is in effect shall be provided upon request of the
Connecting Transmission Owner, except that the Interconnection Customer shall show
proof of insurance to the Connecting Transmission Owner no later than ten (10) Business
Days prior to the anticipated commercial operation date. An Interconnection Customer
of sufficient creditworthiness may propose to self-insure for such liabilities, and such a
proposal shall not be unreasonably rejected.

8.2 The NYISO and Connecting Transmission Owner agree to maintain general liability
insurance or self-insurance consistent with the existing commercial practice. Such
insurance or self-insurance shall not exclude the liabilities undertaken pursuant to this
Agreement.

8.3 The Parties further agree to notify one another whenever an accident or incident occurs
resulting in any injuries or damages that are included within the scope of coverage of
such insurance, whether or not such coverage is sought.

SERVICE AGREEMENT NO. 2975

Article 9 Confidentiality

9.1 Confidential Information shall mean any confidential and/or proprietary information
provided by one Party to the other Party that is clearly marked or otherwise designated
“Confidential.” For purposes of this Agreement all design, operating specifications, and
metering data provided by the Interconnection Customer shall be deemed Confidential
Information regardless of whether it is clearly marked or otherwise designated as such.
Confidential Information shall include, without limitation, information designated as
such by the NYISO Code of Conduct contained in Attachment F to the ISO OATT.

9.2 Confidential Information does not include information previously in the public domain,
required to be publicly submitted or divulged by Governmental Authorities (after notice
to the other Party and after exhausting any opportunity to oppose such publication or
release), or necessary to be divulged in an action to enforce this Agreement. Each Party
receiving Confidential Information shall hold such information in confidence and shall
not disclose it to any third party nor to the public without the prior written authorization
from the Party providing that information, except to fulfill obligations under this
Agreement, or to fulfill legal or regulatory requirements.

9.2.1 Each Party shall employ at least the same standard of care to protect Confidential
Information obtained from the other Parties as it employs to protect its own
Confidential Information.

9.2.2 Each Party is entitled to equitable relief, by injunction or otherwise, to enforce its
rights under this provision to prevent the release of Confidential Information
without bond or proof of damages, and may seek other remedies available at law
or in equity for breach of this provision.

9.3 Notwithstanding anything in this article to the contrary, and pursuant to 18 CFR §
lb.20, if FERC, during the course of an investigation or otherwise, requests
information from one of the Parties that is otherwise required to be maintained in
confidence pursuant to this Agreement, the Party shall provide the requested
information to FERC, within the time provided for in the request for information.
In providing the information to FERC, the Party may, consistent with 18 CFR §
388.112, request that the information be treated as confidential and non-public by
FERC and that the information be withheld from public disclosure. Each Party is
prohibited from notifying the other Parties to this Agreement prior to the release
of the Confidential Information to FERC. The Party shall notify the other Parties
to this Agreement when it is notified by FERC that a request to release
Confidential Information has been received by FERC, at which time either of the
Parties may respond before such information would be made public, pursuant to
18 CFR § 388.112. Requests from a state regulatory body conducting a
confidential investigation shall be treated in a similar manner if consistent with
the applicable state rules and regulations.

9.4 Consistent with the provisions of this article 9, the Parties to this Agreement will
cooperate in good faith to provide each other, Affected Systems, Affected System

SERVICE AGREEMENT NO. 2975

Operators, and state and federal regulators the information necessary to carry out
the terms of the SGIP and this Agreement.

SERVICE AGREEMENT NO. 2975

Article 10 Disputes

10.1 The NYISO, Connecting Transmission Owner and Interconnection Customer agree to
attempt to resolve all disputes arising out of the interconnection process according to the
provisions of this article.

10.2 In the event of a dispute, the Parties will first attempt to promptly resolve it on an
informal basis. The NYISO will be available to the Interconnection Customer and
Connecting Transmission Owner to help resolve any dispute that arises with respect to
performance under this Agreement. If the Parties cannot promptly resolve the dispute on
an informal basis, then any Party shall provide the other Parties with a written Notice of
Dispute. Such notice shall describe in detail the nature of the dispute.

10.3 If the dispute has not been resolved within two (2) Business Days after receipt of the
notice, any Party may contact FERC’s Dispute Resolution Service (“DRS”) for assistance
in resolving the dispute.

10.4 The DRS will assist the Parties in either resolving their dispute or in selecting an
appropriate dispute resolution venue (e.g., mediation, settlement judge, early neutral
evaluation, or technical expert) to assist the Parties in resolving their dispute. The result
of this dispute resolution process will be binding only if the Parties agree in advance.
DRS can be reached at 1-877-337-2237 or via the internet at

http://www.ferc.gov/legal/adr.asp.

10.5 Each Party agrees to conduct all negotiations in good faith and will be responsible for
one-third of any costs paid to neutral third-parties.

10.6 If any Party elects to seek assistance from the DRS, or if the attempted dispute resolution
fails, then any Party may exercise whatever rights and remedies it may have in equity or
law consistent with the terms of this Agreement.

SERVICE AGREEMENT NO. 2975

Article 11 Taxes

11.1 The Parties agree to follow all applicable tax laws and regulations, consistent with FERC
policy and Internal Revenue Service requirements.

11.2 Each Party shall cooperate with the other Parties to maintain the other Parties’ tax status.
Nothing in this Agreement is intended to adversely affect the tax status of any Party
including the status of NYISO, or the status of any Connecting Transmission Owner with
respect to the issuance of bonds including, but not limited to, Local Furnishing Bonds.
Notwithstanding any other provisions of this Agreement, LIPA, NYPA and Consolidated
Edison Company of New York, Inc. shall not be required to comply with any provisions
of this Agreement that would result in the loss of tax-exempt status of any of their Tax-
Exempt Bonds or impair their ability to issue future tax-exempt obligations. For
purposes of this provision, Tax-Exempt Bonds shall include the obligations of the Long
Island Power Authority, NYPA and Consolidated Edison Company of New York, Inc.,
the interest on which is not included in gross income under the Internal Revenue Code.

11.3 LIPA and NYPA do not waive their exemptions, pursuant to Section 201(f) of the FPA,
from Commission jurisdiction with respect to the Commission’s exercise of the FPA’s
general ratemaking authority.

11.4 Any payments due to the Connecting Transmission Owner under this Agreement shall be
adjusted to include any tax liability incurred by the Connecting Transmission Owner with
respect to the interconnection request which is the subject of this Agreement. Such
adjustments shall be made in accordance with the provisions of Article 5.17 of the LGIA
in Attachment X of the ISO OATT. Except where otherwise noted, all costs, deposits,
financial obligations and the like specified in this Agreement shall be assumed not to
reflect the impact of applicable taxes.

SERVICE AGREEMENT NO. 2975

Article 12 Miscellaneous

12.1 Governing Law, Regulatory Authority, and Rules

The validity, interpretation and enforcement of this Agreement and each of its provisions
shall be governed by the laws of the state of New York, without regard to its conflicts of law
principles. This Agreement is subject to all Applicable Laws and Regulations. Each Party
expressly reserves the right to seek changes in, appeal, or otherwise contest any laws, orders, or
regulations of a Governmental Authority.

12.2 Amendment

The Parties may amend this Agreement by a written instrument duly executed by the
Parties, or under article 12.12 of this Agreement.

12.3 No Third-Party Beneficiaries

This Agreement is not intended to and does not create rights, remedies, or benefits of any
character whatsoever in favor of any persons, corporations, associations, or entities other than the
Parties, and the obligations herein assumed are solely for the use and benefit of the Parties, their
successors in interest and where permitted, their assigns. Notwithstanding the foregoing, any
subcontractor of the Connecting Transmission Owner or NYISO assisting either of those Parties
with the Interconnection Request covered by this Agreement shall be entitled to the benefits of
indemnification provided for under Article 7.3 of this Agreement and the limitation of liability
provided for in Article 7.2 of this Agreement.

12.4 Waiver

12.4.1 The failure of a Party to this Agreement to insist, on any occasion, upon strict
performance of any provision of this Agreement will not be considered a waiver
of any obligation, right, or duty of, or imposed upon, such Party.

12.4.2 Any waiver at any time by a Party of its rights with respect to this Agreement
shall not be deemed a continuing waiver or a waiver with respect to any other
failure to comply with any other obligation, right, duty of this Agreement.
Termination or default of this Agreement for any reason by Interconnection
Customer shall not constitute a waiver of the Interconnection Customer’s legal
rights to obtain an interconnection from the NYISO. Any waiver of this
Agreement shall, if requested, be provided in writing.

12.5 Entire Agreement

This Agreement, including all Attachments, constitutes the entire agreement between the
Parties with reference to the subject matter hereof, and supersedes all prior and contemporaneous
understandings or agreements, oral or written, between the Parties with respect to the subject
matter of this Agreement. There are no other agreements, representations, warranties, or
covenants which constitute any part of the consideration for, or any condition to, any Party’s
compliance with its obligations under this Agreement.

SERVICE AGREEMENT NO. 2975

12.6 Multiple Counterparts

This Agreement may be executed in two or more counterparts, each of which is deemed
an original but all constitute one and the same instrument.

12.7 No Partnership

This Agreement shall not be interpreted or construed to create an association, joint
venture, agency relationship, or partnership between the Parties or to impose any partnership
obligation or partnership liability upon any Party. No Party shall have any right, power or
authority to enter into any agreement or undertaking for, or act on behalf of, or to act as or be an
agent or representative of, or to otherwise bind, another Party.

12.8 Severability

If any provision or portion of this Agreement shall for any reason be held or adjudged to
be invalid or illegal or unenforceable by any court of competent jurisdiction or other
Governmental Authority, (1) such portion or provision shall be deemed separate and
independent, (2) the Parties shall negotiate in good faith to restore insofar as practicable the
benefits to each Party that were affected by such ruling, and (3) the remainder of this Agreement
shall remain in full force and effect.

12.9 Security Arrangements

Infrastructure security of electric system equipment and operations and control hardware
and software is essential to ensure day-to-day reliability and operational security. FERC expects
the NYISO, the Connecting Transmission Owner, Market Participants, and Interconnection
Customers interconnected to electric systems to comply with the recommendations offered by
the President’s Critical Infrastructure Protection Board and, eventually, best practice
recommendations from the electric reliability authority. All public utilities are expected to meet
basic standards for system infrastructure and operational security, including physical,
operational, and cyber-security practices.

12.10 Environmental Releases

Each Party shall notify the other Parties, first orally and then in writing, of the release of
any hazardous substances, any asbestos or lead abatement activities, or any type of remediation
activities related to the Small Generating Facility or the Interconnection Facilities, each of which
may reasonably be expected to affect the other Parties. The notifying Party shall: (1) provide the
notice as soon as practicable, provided such Party makes a good faith effort to provide the notice
no later than 24 hours after such Party becomes aware of the occurrence, and (2) promptly
furnish to the other Parties copies of any publicly available reports filed with any governmental
authorities addressing such events.

12.11 Subcontractors

Nothing in this Agreement shall prevent a Party from utilizing the services of any subcontractor as it deems appropriate to perform its obligations under this Agreement; provided,

SERVICE AGREEMENT NO. 2975

however, that each Party shall require its subcontractors to comply with all applicable terms and
conditions of this Agreement in providing such services and each Party shall remain primarily
liable to the other Parties for the performance of such subcontractor.

12.11.1 The creation of any subcontract relationship shall not relieve the hiring
Party of any of its obligations under this Agreement. The hiring Party
shall be fully responsible to the other Parties to the extent provided for in
Articles 7.2 and 7.3 above for the acts or omissions of any subcontractor
the hiring Party hires as if no subcontract had been made; provided,
however, that in no event shall the NYISO or Connecting Transmission
Owner be liable for the actions or inactions of the Interconnection
Customer or its subcontractors with respect to obligations of the
Interconnection Customer under this Agreement. Any applicable
obligation imposed by this Agreement upon the hiring Party shall be
equally binding upon, and shall be construed as having application to, any
subcontractor of such Party.

12.11.2 The obligations under this article will not be limited in any way by any

limitation of subcontractor’s insurance.

12.12 Reservation of Rights

Nothing in this Agreement shall alter the right of the NYISO or Connecting Transmission
Owner to make unilateral filings with FERC to modify this Agreement with respect to any rates,
terms and conditions, charges, classifications of service, rule or regulation under Section 205 or
any other applicable provision of the Federal Power Act and FERC’s rules and regulations
thereunder which rights are expressly reserved herein, and the existing rights of the Interconnection Customer to make a unilateral filing with FERC to modify this Agreement under
any applicable provision of the Federal Power Act and FERC’s rules and regulations are also
expressly reserved herein; provided that each Party shall have the right to protest any such filing
by another Party and to participate fully in any proceeding before FERC in which such
modifications may be considered. Nothing in this Agreement shall limit the rights of the Parties
or of FERC under Sections 205 or 206 of the Federal Power Act and FERC’s rules and
regulations, except to the extent that the Parties otherwise agree as provided herein.

12.13 Modifications Related to NYISO’s Compliance with Order No. 2023

If, as part of the NYISO’s compliance proceeding at the Commission in response to
Order No. 2023, the Commission directs that the NYISO modify the pro forma Standard Small
Generator Interconnection Agreement located in Appendix 7 of Attachment Z of the ISO OATT,
the Parties shall amend and restate this Agreement to incorporate the modifications; provided,
however, the Parties may agree to include in the amended and restated agreement non-
conforming changes to any terms of the pro forma Standard Small Generator Interconnection
Agreement that have been modified to comply with the Commission’s order, which non-
conforming modifications must be filed with the Commission for its acceptance.

Sunny Central inverters each paired with a pad mounted 2750 kVA transformer (34.5 kV wye-
grounded, 600V Delta, 5.75 impedance, X/R 10.6). The output of the eight (8) step-up
transformers is aggregated into two (2) 34.5 kV medium voltage collection circuits (“Collection
Feeder Lines”). The Collection Feeder Lines run to a collector station (the “Beutel Road Collector
Station”) where the power is stepped up to 115 kV via a 15/20/25MVA 115 kV/34.5 kV/13.8k
transformer.

The Point of Interconnection (“POI”) for the Small Generating Facility is Connecting
Transmission Owner’s 115 kV Coffeen-West Adams Line 2 via tap located approximately 3.8
miles from Connecting Transmission Owner’s Coffeen Substation and 10.2 miles from Connecting
Transmission Owner’s West Adams Substation. The Small Generating Facility will interconnect
to the Connecting Transmission Owner’s115 kV Coffeen-West Adams Line 2 via a tap (the “Line
2 Tap”). The Point of Change of Ownership (“PCO”) shall be at the line side connection of the
Interconnection Customer’s disconnect switch located on the Interconnection Customer’s
termination structure inside the Beutel Road Collector Station. The Connecting Transmission
Owner shall own the insulators, whips and hardware connections to the Interconnection
Customer’s disconnect switch. The POI and PCO are detailed on Figure 1 in Attachment 3.

B. INTERCONNECTION CUSTOMER’S INTERCONNECTION FACILITIES

The Interconnection Customer’s Interconnection Facilities (“ICIF”) include all of the
facilities between the Interconnection Customer’s side of the PCO and the Small Generating
Facility, except the Connecting Transmission Owner-owned revenue metering described in Section
