1.8

Reactive Power and Primary Frequency Response

1.8.1 Power Factor Design Criteria

4


SERVICE AGREEMENT NO. 2544

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 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

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

5

 



SERVICE AGREEMENT NO. 2544

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

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.

6

 



SERVICE AGREEMENT NO. 2544

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.

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.

7

 



SERVICE AGREEMENT NO. 2544

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.

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.

18

 



SERVICE AGREEMENT NO. 2544

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.

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 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 60 calendar days,

the Breaching Party shall commence such cure within 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

20

SERVICE AGREEMENT NO. 2544

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 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

8.3

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.

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.

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

OTHER SYSTEM UPGRADE FACILITIES

The interconnection of the Small Generating Facility will require the following System

Upgrade Facilities at the Connecting Transmission Owner’s Meco and Rotterdam Substations.

1. Meco Substation

All modifications shall be completed in the Meco Substation yard and control house. (It

is assumed that all existing wiring trays and panels have sufficient capacity to accommodate the

changes.)

6-1

 



SERVICE AGREEMENT NO. 2544

a) Line 22 Protection Packages

The existing Line 22 protection packages and breaker control relays at Meco Substation

cannot accommodate the Small Generating Facility and shall be replaced. The "A" package will

be converted to a POTT scheme consisting of an ERL Phase LPRO 4000 and GARD 8000 using

leased fiber, and the “B” package protection will be a step distance scheme consisting of SEL-

311C. Panel 8 will be reskinned and all new relays along with 43PT and 43TT switches will be

installed in this panel. The “A” and “B” Package line protection shall perform breaker failure

protection, and the existing reclosing relay will be replaced with a SEL 351-6. The existing PT

throwover relay (HGA) between breakers R22 and R15 will be moved from Panel 8 to Panel 9.

DTT will be sent to Interconnection Customer for a line relay operation, R22 breaker failure and

if R22 is open. DTT for breaker failure will be received from the Pattersonville Collector

Substation. An SEL-351-6 will be added for DTT receive and will be used to trip and drive

reclosing to lockout. The GARD 8000 installed for POTT has spare channels which will be used

for DTT.

b) Controls and Integration

The existing RTU is sufficient for the scope of this Small Generating Facility. Spare I/O

points shall be used to accommodate the additions required. However, the existing SEL-2020

communications processer at the station does not have any spare ports, therefore a SEL2032

shall be installed to interface the microprocessor relays with the RTU and allow for remote

retrieval of fault records.

c) Telecommunications

The Meco Substation has an existing Frontier Communications copper facility terminated

in an outdoor high voltage protection (HVP) Positron Telecom shelf. One (1) DS1 circuit from

the Meco Substation to the Pattersonville Collector Substation will be ordered on the Frontier

Communications copper facility to support Line 10 DTT. The DS1 will be extended from the

Positron Telecom demarcation to the GARD 8000 rack location using Cat 6 cable. The DS1

circuit will go from Frontier Communications territory to Pattersonville Telephone Company

territory. In addition, one (1) DS1 circuit from Connecting Transmission Owner’s Meco

Substation to its Rotterdam Substation will be ordered on the Frontier Communications copper

facility to support the Line 22/10 POTT. The DS1 will extend from the Positron Telecom

demarcation to the GARD 8000 rack location using Cat 6 cable. The DS1 circuit from

Connecting Transmission Owner’s Meco Substation to its Rotterdam Substation will go from

Frontier Communications territory to Verizon territory.

2.

Rotterdam Substation

All modifications shall be completed in the Rotterdam Substation yard and control house.

(It is assumed that all existing wiring trays and panels have sufficient capacity to accommodate

the changes.)

6-2

 



SERVICE AGREEMENT NO. 2544

a) Line 10 Protection Packages

The existing Line 10 protection packages and breaker control relays at Rotterdam

Substation cannot accommodate interconnection of the Small Generating Facility and shall be

replaced. The existing line relays for Line 10 in panel 68 and reclosing relays on panel 16 will

be removed, and the asbestos panels in control house 2 shall be replaced with sheet metal panels.

The "A" package will be converted to a POTT scheme consisting of an ERL Phase LPRO 4000

and GARD 8000 using leased fiber. The “B” package protection shall be a step distance scheme

consisting of SEL-311C. The new “A” and “B” relays along with 43PT and 43TT switches shall

be installed in panel 12. The “A” and “B” Package line protection shall perform breaker failure

protection. Sync check and reclosing (ACR) relays in panel 16 will be replaced with a SEL 351-

6. The addition of “B” relaying to Line 10 shall require the spare CT to be wired into the relay.

DTT will be sent to the Pattersonville Collector Substation for a line relay operation, R10

breaker failure and if R10 is open. DTT for breaker failure will be received from the

Pattersonville Collector Substation. An SEL-351-6 will be added for DTT receive and will be

used to trip and drive reclosing to lockout. The GARD 8000 installed for POTT has spare

channels which will be used for DTT.

b) Controls and Integration

The existing RTU is sufficient for interconnection of the Small Generating Facility and

spare I/O points shall be used to accommodate the additions required. The existing RE-01

control switches and 43 latch switch relays for both R10 and R63 breakers shall be replaced with

RE-01 control switches and RE-43/A/M latch switch relays as specified by Connecting

Transmission Owner’s current standard due to asbestos panel 16 being replaced by a sheet metal

panel. (Currently, the switches for R10 and R63 all reside in panel 16.) The new protection

relays shall be connected to spare serial ports on the SEL-2020 communications processor to

allow for remote retrieval of faults records.

c) Telecommunications

Connecting Transmission Owner’s Rotterdam Substation has an existing Verizon fiber

facility terminated in control building 2. This facility is operational and no upgrades are required

to order additional circuits. One DS1 circuit from the Rotterdam Substation to the Pattersonville

Collector Substation will be ordered on the Verizon fiber facility to support Line 22/10 DTT.

The DS1 will be extended from the Verizon telco demark in Control Building 2 to the GARD

8000 rack location using Cat 6 cable. The DS1 circuit from the Rotterdam Substation to the

Pattersonville Collector Substation will go from Verizon territory to Pattersonville Telephone

Company territory. One DS1 circuit from Connecting Transmission Owner’s Rotterdam

Substation to its Meco Substation will be ordered on the Verizon fiber facility to support Line

22/10 POTT. The DS1 will be extended from the Verizon demarcation in control building 2 to

the GARD 8000 rack location using Cat 6 cable. The DS1 circuit from Connecting Transmission

Owner’s Rotterdam Substation to its Meco Substation will go from Verizon territory to Frontier

Communications territory.
