In no event shall NYISO have any liability whatever to Developer for liquidated damages associated with the engineering, procurement or construction of Attachment Facilities or System Upgrade Facilities or System Deliverability Upgrades.
The Connecting Transmission Owner shall transfer operational control of the Connecting Transmission Owner’s Attachment Facilities and Stand Alone System Upgrade Facilities to the NYISO upon completion of such facilities.
Connecting Transmission Owner shall invoice Developer for such costs pursuant to Article 12 and shall use due diligence to minimize its costs. In the event Developer suspends work by Connecting Transmission Owner required under this Agreement pursuant to this Article 5.16, and has not requested Connecting Transmission Owner to recommence the work required under this Agreement on or before the expiration of three (3) years following commencement of such suspension, this Agreement shall be deemed terminated. The three-year period shall begin on the date the suspension is requested, or the date of the written notice to Connecting Transmission Owner and NYISO, if no effective date is specified.
At Connecting Transmission Owner’s request, Developer shall provide Connecting Transmission Owner with a report from an independent engineer confirming its representation in clause (iii), above. Connecting Transmission Owner represents and covenants that the cost of the Connecting Transmission Owner’s Attachment Facilities paid for by Developer will have no net effect on the base upon which rates are determined.
Connecting Transmission Owner shall not include a gross-up for the cost consequences of any current tax liability in the amounts it charges Developer under this Agreement unless (i) Connecting Transmission Owner has determined, in good faith, that the payments or property transfers made by Developer to Connecting Transmission Owner should be reported as income subject to taxation or (ii) any Governmental Authority directs Connecting Transmission Owner to report payments or property as income subject to taxation; provided, however, that Connecting Transmission Owner may require Developer to provide security, in a form reasonably acceptable to Connecting Transmission Owner (such as a parental guarantee or a letter of credit), in an amount equal to the cost consequences of any current tax liability under this Article 5.17. Developer shall reimburse Connecting Transmission Owner for such costs on a fully grossed-up basis, in accordance with Article 5.17.4, within thirty (30) Calendar Days of receiving written notification from Connecting Transmission Owner of the amount due, including detail about how the amount was calculated.
This indemnification obligation shall terminate at the earlier of (1) the expiration of the ten-year testing period and the applicable statute of limitation, as it may be extended by the Connecting Transmission Owner upon request of the IRS, to keep these years open for audit or adjustment, or (2) the occurrence of a subsequent taxable event and the payment of any related indemnification obligations as contemplated by this Article 5.17.
For this purpose, (i) Current Taxes shall be computed based on Connecting Transmission Owner’s composite federal and state tax rates at the time the payments or property transfers are received and Connecting Transmission Owner will be treated as being subject to tax at the highest marginal rates in effect at that time (the “Current Tax Rate”), and (ii) the Present Value Depreciation Amount shall be computed by discounting Connecting Transmission Owner’s anticipated tax depreciation deductions as a result of such payments or property transfers by Connecting Transmission Owner’s current weighted average cost of capital. Thus, the formula for calculating Developer’s liability to Connecting Transmission Owner pursuant to this Article 5.17.4 can be expressed as follows: (Current Tax Rate x (Gross Income Amount - Present Value of Tax Depreciation))/(1 - Current Tax Rate).
Developer’s estimated tax liability in the event taxes are imposed shall be stated in Appendix A, Attachment Facilities and System Upgrade Facilities and System Deliverability Upgrades.
Connecting Transmission Owner shall keep Developer fully informed of the status of such request for a private letter ruling and shall execute either a privacy act waiver or a limited power of attorney, in a form acceptable to the IRS, that authorizes Developer to participate in all discussions with the IRS regarding such request for a private letter ruling. Connecting Transmission Owner shall allow Developer to attend all meetings with IRS officials about the request and shall permit Developer to prepare the initial drafts of any follow-up letters in connection with the request.
Developer shall pay to Connecting Transmission Owner on a periodic basis, as invoiced by Connecting Transmission Owner, Connecting Transmission Owner’s documented reasonable costs of prosecuting such appeal, protest, abatement or other contest. At any time during the contest, Connecting Transmission Owner may agree to a settlement either with Developer’s consent or after obtaining written advice from nationally-recognized tax counsel, selected by Connecting Transmission Owner, but reasonably acceptable to Developer, that the proposed settlement represents a reasonable settlement given the hazards of litigation. Developer’s obligation shall be based on the amount of the settlement agreed to by Developer, or if a higher amount, so much of the settlement that is supported by the written advice from nationally-recognized tax counsel selected under the terms of the preceding sentence. The settlement amount shall be calculated on a fully grossed-up basis to cover any related cost consequences of the current tax liability. Any settlement without Developer’s consent or such written advice will relieve Developer from any obligation to indemnify Connecting Transmission Owner for the tax at issue in the contest.
(i) Any payment made by Developer under this Article 5.17 for taxes that is attributable to the amount determined to be non-taxable, together with interest thereon,
(ii) Interest on any amounts paid by Developer to Connecting Transmission Owner for such taxes which Connecting Transmission Owner did not submit to the taxing authority, calculated in accordance with the methodology set forth in FERC’s regulations at 18 C.F.R. §35.19a(a)(2)(iii) from the date payment was made by Developer to the date Connecting Transmission Owner refunds such payment to Developer, and
(iii) With respect to any such taxes paid by Connecting Transmission Owner, any refund or credit Connecting Transmission Owner receives or to which it may be entitled from any Governmental Authority, interest (or that portion thereof attributable to the payment described in clause (i), above) owed to the Connecting Transmission Owner for such overpayment of taxes (including any reduction in interest otherwise payable by Connecting Transmission Owner to any Governmental Authority resulting from an offset or credit); provided, however, that Connecting Transmission Owner will remit such amount promptly to Developer only after and to the extent that Connecting Transmission Owner has received a tax refund, credit or offset from any Governmental Authority for any applicable overpayment of income tax related to the Connecting Transmission Owner’s Attachment Facilities.
The intent of this provision is to leave both the Developer and Connecting Transmission Owner, to the extent practicable, in the event that no taxes are due with respect to any payment for Attachment Facilities and System Upgrade Facilities and System Deliverability Upgrades hereunder, in the same position they would have been in had no such tax payments been made.
In the case of Merchant Transmission Facility modifications that do not require Developer to submit an Interconnection Request, the NYISO shall provide, within sixty (60) Calendar Days (or such other time as the Parties may agree), an estimate of any additional modifications to the New York State Transmission System, Connecting Transmission Owner’s Attachment Facilities or System Upgrade Facilities or System Deliverability Upgrades necessitated by such Developer modification and a good faith estimate of the costs thereof. The Developer shall be responsible for the cost of any such additional modifications, including the cost of studying the impact of the Developer modification.
Each Party will promptly advise the appropriate other Party if it detects or otherwise learns of any metering, telemetry or communications equipment errors or malfunctions that require the attention and/or correction by that other Party. The Party owning such equipment shall correct such error or malfunction as soon as reasonably feasible.
In addition:
NYISO and Connecting Transmission Owner shall use Reasonable Efforts to minimize the effect of such actions or inactions on the Merchant Transmission Facility or the Developer Attachment Facilities. NYISO or Connecting Transmission Owner may, on the basis of technical considerations, require the Merchant Transmission Facility to mitigate an Emergency State by taking actions necessary and limited in scope to remedy the Emergency State, including, but not limited to, directing Developer to shut-down, start-up, increase or decrease the real or reactive power output of the Merchant Transmission Facility; implementing a reduction or disconnection pursuant to Article 13.4.2; directing the Developer to assist with blackstart (if available) or restoration efforts; or altering the outage schedules of the Merchant Transmission Facility and the Developer Attachment Facilities. Developer shall comply with all of the NYISO and Connecting Transmission Owner’s operating instructions concerning Merchant Transmission Facility real power and reactive power output within the manufacturer’s design limitations of the Merchant Transmission Facility’s equipment that is in service and physically available for operation at the time, in compliance with Applicable Laws and Regulations.
A Party may change the notice information in this Agreement by giving five (5) Business Days written notice prior to the effective date of the change.
Except as stated below, the Indemnifying Party shall have the right to assume the defense thereof with counsel designated by such Indemnifying Party and reasonably satisfactory to the Indemnified Party. If the defendants in any such action include one or more Indemnified Parties and the Indemnifying Party and if the Indemnified Party reasonably concludes that there may be legal defenses available to it and/or other Indemnified Parties which are different from or additional to those available to the Indemnifying Party, the Indemnified Party shall have the right to select separate counsel to assert such legal defenses and to otherwise participate in the defense of such action on its own behalf. In such instances, the Indemnifying Party shall only be required to pay the fees and expenses of one additional attorney to represent an Indemnified Party or Indemnified Parties having such differing or additional legal defenses.
The Indemnified Party shall be entitled, at its expense, to participate in any such action, suit or proceeding, the defense of which has been assumed by the Indemnifying Party. Notwithstanding the foregoing, the Indemnifying Party (i) shall not be entitled to assume and control the defense of any such action, suit or proceedings if and to the extent that, in the opinion of the Indemnified Party and its counsel, such action, suit or proceeding involves the potential imposition of criminal liability on the Indemnified Party, or there exists a conflict or adversity of interest between the Indemnified Party and the Indemnifying Party, in such event the Indemnifying Party shall pay the reasonable expenses of the Indemnified Party, and (ii) shall not settle or consent to the entry of any judgment in any action, suit or proceeding without the consent of the Indemnified Party, which shall not be unreasonably withheld, conditioned or delayed.
If requested by a Party receiving information, the Party supplying the information shall provide in writing, the basis for asserting that the information referred to in this Article warrants confidential treatment, and the requesting Party may disclose such writing to the appropriate Governmental Authority. Each Party shall be responsible for the costs associated with affording confidential treatment to its information.
If the Developer’s data is different from what was originally provided to Connecting Transmission Owner and NYISO pursuant to an Interconnection Study Agreement among Connecting Transmission Owner, NYISO and Developer and this difference may be reasonably expected to affect the other Parties’ facilities or the New York State Transmission System, but does not require the submission of a new Interconnection Request, then NYISO will conduct appropriate studies to determine the impact on the New York State Transmission System based on the actual data submitted pursuant to this Article 24.3. Such studies will provide an estimate of any additional modifications to the New York State Transmission System, Connecting Transmission Owner’s Attachment Facilities, or System Upgrade Facilities or System Deliverability Upgrades based on the actual data and a good faith estimate of the costs thereof. The Developer shall not begin Trial Operation until such studies are completed. The Developer shall be responsible for the cost of any modifications required by the actual data, including the cost of any required studies.
Developer shall provide the Connecting Transmission Owner and NYISO validated test recordings showing the responses of its Merchant Transmission Facility.
Subsequent to the Commercial Operation Date, the Developer shall provide Connecting Transmission Owner and NYISO any information changes due to equipment replacement, repair, or adjustment. Connecting Transmission Owner shall provide the Developer and NYISO any information changes due to equipment replacement, repair or adjustment in the directly connected substation or any adjacent Connecting Transmission Owner substation that may affect the Merchant Transmission Facility or Developer Attachment Facilities equipment ratings, protection or operating requirements. The Developer and Connecting Transmission Owner shall provide such information no later than thirty (30) Calendar Days after the date of the equipment replacement, repair or adjustment.
IN WITNESS WHEREOF, the Parties have executed this LGIA in duplicate originals, each of which shall constitute and be an original effective Agreement between the Parties.

NYISO Agreements --> LGIA Among NYISO, Con Edison, and HTP
MERCHANT TRANSMISSION FACILITY AND DEVELOPER ATTACHMENT FACILITIES PERFORMANCE SPECIFICATIONS
The Merchant Transmission Facility and DAF shall be designed for continuous delivery to the POI as described under the following system conditions:
Developer shall design the Merchant Transmission Facility to operate within the voltage guidelines as specified in Article 9.5.2.
The nominal frequency of the New York State Transmission System is 60 Hz. The frequency may deviate by ± 0.05Hz from the nominal value during normal steady-state conditions. During extreme system disturbances, the system frequency may deviate from the nominal value by ± 0.07Hz. For very extreme disturbances such as system separation, frequency deviations may be ± 1.5Hz.
Connecting Transmission Owner typically operates the 345kV AC bus at a higher voltage than 1.0pu. Under infrequent operating conditions the system voltage may be reduced to less than 1.0pu and the system reactive requirements may be such that the Merchant Transmission Facility may reduce import levels during such conditions.
Detailed control system capabilities and features will be developed and agreed upon by the Developer, Connecting Transmission Owner, NYISO and PJM at the conclusion of the detailed equipment design of the Merchant Transmission Facility.
The primary control components, including their power supply and communications involved in the control of real power, reactive power, AC current, AC voltage, DC voltage, and DC current will be redundant with an active and standby system. The active and standby control components will be continuously monitored for proper operation and will transfer automatically from active to standby when faults are detected in the active system. The active and standby components will be continuously updated to minimize disturbances during and after transfers between the active and standby systems.
Transfer of DC or AC power supplies for the control system will not cause a disturbance to the operation of the Merchant Transmission Facility. Disturbances to or the loss of control of telecommunications channels will not cause unstable operation of the Merchant Transmission Facility.
General control features will include the following:
The converter station will be equipped with a supervisory control and data acquisition (“SCADA”) hardware I/O to interconnect with the Connecting Transmission Owner SCADA remote terminal unit (“RTU”) and dispatch system. Detailed SCADA I/O and RTU specifications will be mutually developed and implemented at a later date.
The Merchant Transmission Facility shall provide data to the Connecting Transmission Owner SCADA system for the purpose of monitoring key parameters such as 345kV voltage, bus frequency, real and reactive power flow into the AC system, line current, real-time indication of loading, and reactive bank status. Requirements for the communications between the Merchant Transmission Facility operators, NYISO, PJM, PSE&G, and Connecting Transmission Owner will be mutually developed and implemented at a later date, as necessary.
A local and remote operator control and communications conceptual diagram will be developed and included in the Merchant Transmission Facility design reports.
The Merchant Transmission Facility shall be designed and operated in accordance with Article 9.5 of this Agreement. In addition, the Merchant Transmission Facility shall maintain stable power transfer within a tolerance which is the lesser deviation of 3.0% or 6MW when the AC voltages and frequency vary.
The reactive compensation control system shall allow the AC bus voltage at the West 49th Street 345kV Substation 345kV bus to be regulated to within 0.02p.u relative to the voltage regulation set point when in AC bus voltage regulation mode, at any power transfer within the Merchant Transmission Facility system normal capacity, and subject to the constraints of the total installed reactive supply and reactive absorption capability. Reactive absorption capacity comprises 1 shunt reactor. The voltage set point shall be selectable between 0.95pu and 1.05pu.
Continuous operation of the Merchant Transmission Facility system shall not be disrupted by the following minor disturbances.
Disruption of continuous operation shall be defined as an inverter commutation failure, or as any deviation from the pre-disturbance power transfer greater than 50% of the pre-disturbance value for a duration in excess of 0.02 seconds. The above shall apply for the normal range of short-circuit capacity.
Operation of the Merchant Transmission Facility may be temporarily suspended for disturbances more severe than defined in Minor AC Voltage Disturbances above. Unless the voltage disturbance at either terminal of the Merchant Transmission Facility exceeds the extreme disturbance criteria listed in Criteria for Permanent Blocking and Tripping below, the Merchant Transmission Facility shall commence recovery within one cycle of the recovery of the PJM and New York State Transmission System voltage to a value greater than 0.8pu in all phases.
The Merchant Transmission Facility system shall be permitted, but not required, to trip for the following extreme system conditions:
Figure G-1 Voltage thresholds for permanent blocking and converter station tripping
Figure G-2 Voltage imbalance (negative sequence component) threshold for permanent blocking and converter station tripping.
Figure G-3 Fundamental frequency deviation threshold for permanent blocking and converter station tripping
The response of the power controls to manual or automatic modifications in power order shall be prompt and stable. Any oscillatory performance of the power transfer shall be well damped with an overshoot no more than 10% of the requested change. Reactive power balance shall be maintained during routine power ramping operations. If discrete changes in active power are necessary while ramping between power levels the discrete changes will not exceed 25MW.
During contingency conditions power transfers may need to be reduced substantially and rapidly. The action of reducing the power transfer in response to an externally provided trigger is called power runback. The design of the Merchant Transmission Facility shall allow for pre‑programmed power runback levels. Runback execution shall not require a reversal of power direction.
When transition to a specified or predetermined runback level is requested, power shall be reduced to the programmed runback level at a programmable rate no less than 500 ms. The available runback rates shall allow runback to be completed as fast as 500 ms from the receipt of the runback signal by the Merchant Transmission Facility system. (The runback levels are maximum power limits; if the Merchant Transmission Facility is dispatched to less than the runback level at the time of runback command, no power change is necessary.) If a runback level of less than 60MW is specified, the Merchant Transmission Facility will be allowed to trip upon receipt of the runback signal.
To the extent runback or special protection systems are required; Developer shall be responsible for obtaining the appropriate approvals and is responsible for all systems costs including maintenance. Any runback or special protection systems shall conform to applicable Connecting Transmission Owner, NYISO, and NPCC standards, as applicable.
Following any disturbance that causes the Merchant Transmission Facility to deviate from the initial equilibrium AC and DC conditions, the Merchant Transmission Facility shall be controlled toward an acceptable equilibrium as rapidly as possible. The post-disturbance equilibrium conditions shall be identical to the pre-disturbance conditions if there is no change in the AC system state. If there are changes to the AC system state, such as opening of a line, then the post-disturbance Merchant Transmission Facility equilibrium condition may or may not be identical to the pre-disturbance conditions. Recovery performance, as used within this Technical Specification, refers to the action of resuming the pre-disturbance equilibrium conditions or successfully readjusting Merchant Transmission Facility operation to accommodate changes in the AC system caused by the disturbance. The actual values and set points for the performance characteristics described in this section will be determined as part of Merchant Transmission Facility final design.
Recovery time is defined as the elapsed time from the instant of disturbance initiation until the Merchant Transmission Facility is within 10% of the lesser of the dispatched power order or the achievable power transfer as limited by the AC voltage magnitude, and the reactive power interchange with the AC system at the West 49th Street 345kV Substation 345kV bus is within ±100MVAR of the expected post-disturbance value. If the initiating disturbance is a fault causing any phase voltage at either the PSE&G Bergen 230kV AC bus or the West 49th Street 345kV Substation 345kV AC bus to decrease below 80% of the pre-disturbance value, then recovery time shall be measured from the time of fault clearing.
5.6.3 Commutation Failure Recovery
The Merchant Transmission Facility shall recover from commutation failures, other than those caused by faults reducing inverter AC bus voltage to less than 80% of the pre-disturbance value, within 250 ms without subsequent commutation failures or sustained oscillations.
The Merchant Transmission Facility system operation, if disrupted by an AC system fault, shall recover from such faults in 350 ms without subsequent commutation failures or sustained oscillations.
5.6.5 Irrecoverable Faults
The Merchant Transmission Facility shall not be required to recover from the following:
Developer shall take immediate action to correct any situation causing the Merchant Transmission Facility system to fail to meet the disturbance recovery performance requirements.
Developer shall ensure that the Merchant Transmission Facility’s control performance is stable for all foreseeable AC system conditions, including any single or double contingencies on either the PJM or NYISO systems. Developer is responsible for determining the range of short-circuit capacities at the terminals, for any single or double contingency outages including failure of special protective systems. Developer shall ensure that harmonic instabilities, including core saturation instability, will not occur.
Stable control performance shall be defined as adequately damped performance, free of persistent oscillations in real or reactive power into the West 49th Street 345kV Substation 345kV AC bus. In addition, stable control performance shall require that the Merchant Transmission Facility system shall not suffer repetitive commutation failures.
If system conditions are found to create system control or harmonic instability in the Merchant Transmission Facility control system, including those reducing the short-circuit capacity below the calculated minimum post-contingency short-circuit capacity at the West 49th Street 345kV Substation 345kV AC bus, or the PSE&G Bergen 230kV AC bus, then adequate protective functions shall be included in the Merchant Transmission Facility system design to detect the instability and promptly trip the Merchant Transmission Facility system or take other effective corrective action.
(a) A detailed Dynamic Performance Study (“DPS”) shall be performed to verify that the response to disturbances does not cause instability in the Merchant Transmission Facility, does not cause conditions that will damage the equipment and does behave according to the Merchant Transmission Facility design.
The DPS report shall provide descriptions of the performance to the cases listed below where applicable. The case descriptions shall include the simulation setup and plots of relevant AC and DC quantities. System data needed for the simulations described below shall be obtained from Connecting Transmission Owner.
1. DPS Case
2. Simulation Setup
Certain design verification studies, including, but not limited to the following, require use of cycle-by-cycle simulation using a transient network analyzer, special purpose simulator or a digital computer program equivalent:
Reactive power support shall be provided as specified in Article 9.5 concurrently with meeting all harmonic performance requirements.
Energization/de-energization of the Merchant Transmission Facility system terminal equipment, including AC cables, and routine switching of supplemental reactive compensation equipment (capacitors and reactors) must not cause transients and sustained changes in the voltage that may be considered power quality violations.
The limitation to voltage change on switching specified above shall not apply to station energization. During station energization, voltage change will be limited to 3.5% or 0.035pu. At no time will the fundamental-frequency voltage be raised above 1.05pu of 345kV, or lowered below 0.95pu at the West 49th Street 345kV Substation 345kV bus by any reactive bank or cable switching, including banks or cables switched during energization.
In order to reduce the impact of reactive bank and AC cable switching on sensitive loads, the severity of voltage transients due to switching shall be minimized. Equipment switching at the converter station or the 345kV AC cable interconnecting this terminal with West 49th Street 345kV Substation, including switching of capacitor banks, harmonic filters, AC cables, and shunt reactors, shall be performed using point-on-wave synchronous switching. Switching of the Merchant Transmission Facility at the West 49th Street 345kV Substation shall be performed using pre-insertion resistors. The closing time tolerance for synchronous switching shall be 1 ms. However, the closing time tolerance may be as high as 1.5 ms for operation during ambient temperature conditions of less than -10 C .
Switching of a reactive compensation bank, if required, at either converter terminal shall not interfere with the control and continuity of power transfer on the Merchant Transmission Facility system or disrupt normal control of power transfer or voltage regulation at the converter terminals.
Binary switching, which is the approximately simultaneous switching of more than one reactive compensation bank or cable, shall not be used to achieve voltage change on switching requirements.
To maintain real and reactive power levels within the range set forth in Article 9.5.1, an automatic reactive power control system including discrete reactive bank switching shall be provided with the following two control modes:
1. AC bus voltage regulation. In this mode, an incrementally switched or continuously controlled source of reactive power is adjusted to maintain the AC bus voltage at the West 49th Street 345kV Substation 345kV bus within the range set forth in Article 9.5.1. The set points this control mode will be adjustable, and shall be set according to directives from the responsible Connecting Transmission Owner system dispatcher. The design of the reactive compensation system shall allow the AC bus voltage at the West 49th Street 345kV Substation 345kV bus to be regulated to within 0.02pu relative to the voltage regulation set point at any power transfer within the Merchant Transmission Facility system normal capacity, subject to the constraints of the total installed reactive supply and reactive absorption capability.
2. Reactive power exchange regulation. In this mode, the incrementally switched or continuously controlled source of reactive power is adjusted to maintain the reactive power exchange with the AC system at the West 49th Street 345kV Substation 345kV bus within the range set forth in Article 9.5.1. This control mode shall be effective only if the West 49th Street 345kV Substation 345kV AC bus voltage is within the prescribed range of 0.95pu to 1.05pu. If the converter station is operating in reactive power exchange regulation mode, and the AC voltage at the West 49th Street 345kV Substation 345kV bus either falls below a low-voltage threshold, or increases above a high-voltage threshold, the control mode shall automatically switch to the AC bus voltage regulation mode. Reactive power exchange limits shall be adjustable based on real time system conditions.
The reactive power controls shall ensure at all times that the harmonic filters, required to meet the performance specified in accordance with IEEE Standard 519, are energized. The harmonic filter requirement shall take precedence over the automatic voltage and reactive power exchange control modes, unless the minimum equipment to meet harmonic requirements cause the voltage at the POI to exceed 1.05pu of 345kV. For the expected range of normal conditions, sufficient reactive absorption shall be installed to avoid this situation.
Any equipment de-energized for any reason except for protective tripping or removal from service for maintenance shall be available for re-energization within five minutes.
The following performance indices are to be met by the Merchant Transmission Facility during normal operation. All performance indices reflect the incremental contribution of the Merchant Transmission Facility. Normal operation is defined as follows:
The AC harmonic filters shall be designed in accordance with the performance criteria below, as measured at the POI for the frequency range from 60 to 3kHz.
The performance criteria for normal operation shall be met over the entire normal power transfer range in rectifier and inverter operation.
The performance criteria shall be met considering combined detuning effects on tuned filters caused by frequency and temperature variations.
The voltage distortion caused by the Merchant Transmission Facility at the Connecting Transmission Owner 345kV bus of the West 49th Street Substation shall be:
Telephone interference shall be limited by the telephone influence factor (“TIF”) as defined in Section 13.2 of the “Electric Power Research Institute High-Voltage Direct Current Handbook.” Power quality of the associated filtering systems shall be such that the incremental contribution of TIF associated with the Merchant Transmission Facility at the Points of Interconnection shall be based on a design goal not to not exceed 40.
Developer shall determine the Merchant Transmission Facility operating conditions which produce worst case harmonic generation.
Imbalances leading to non-characteristic harmonics shall be considered as follows:
Developer shall provide a procedure to measure the harmonic voltages and currents at the interconnection with the West 49th Street 345kV Substation 345kV bus as part of the commissioning test program.
Developer may implement independent monitoring of the performance indices at its own discretion.
The Merchant Transmission Facility will include AC high frequency filters. The following four general frequency ranges shall be considered in the design of the filters:
PLC systems exist on the Connecting Transmission Owner System. In addition to potential interference due to noise injected by the converters in the PLC channel frequency range from 30kHz to 400kHz, PLC receiver input overload due to energy in the 4kHz to 10kHz region shall be avoided. The proposed equipment comprising the Merchant Transmission Facility system shall be designed to avoid interference with PLC systems due to any injected electrical noise or harmonics, even if this interference is outside of the PLC channel frequency range. Interference in the frequency range of 30kHz to 200kHz should be especially avoided.
Harmonic and electrical noise conducted or radiated from the Merchant Transmission Facility system shall not interfere with any PLC system, including interference to PLC operation via input stage overload due to energy outside of the carrier frequency range. The contribution to voltage across the drain coils of PLC coupling capacitors shall be less than 5% of their design maximum.
Developer shall predict maximum PLC interference voltage on the West 49th Street 345kV Substation 345kV bus.
The temporary overvoltages (“TOV”) potentially caused by the Merchant Transmission Facility system shall be defined to include, but not be limited to, all voltage components resulting from the following causes:
1. Fundamental-frequency voltages resulting from capacitive compensation in excess of the system requirements, or excess uncompensated AC cable charging capacitance;
2. Harmonic voltages caused by saturation of any transformer or reactor within the Merchant Transmission Facility system, including both symmetric saturation caused by excess applied voltage, and asymmetric saturation resulting from flux offset during disturbances or from direct current injected by any power electronic device or converter included in the Merchant Transmission Facility,
3. Harmonic voltages caused by characteristic and non-characteristic harmonics injected into the AC system by any component of the Merchant Transmission Facility, particularly during unbalanced faults on the interconnecting AC systems, and
4. Overvoltages caused by control failure or other mis-operation of the Merchant Transmission Facility.
5. Overvoltages caused by Very High Frequency (“VHF”) surges resulting from switching West 49th Street 345kV Substation GIS equipment.
The magnitude and duration of temporary overvoltages shall be quantified by the temporary overvoltage envelope. The temporary voltage envelope for a given bus is defined as the plot of voltage versus time, for which the voltage value at any instant of time is the maximum instantaneous pu value of any phase-to-ground or phase-to-phase voltage magnitude (absolute value) during the preceding 16.6666 milliseconds. The crest voltage base for per-unitization of phase-to-ground voltages is times the nominal line-to-line rms voltage, and the base for phase-to-phase voltages is
times the nominal line-to-line rms AC bus voltage.
Temporary overvoltage duration limitations in this specification are cumulative for a related sequence of events. A related sequence of events is defined to be all events occurring as a consequence of an initiating AC or DC system contingency, including failure of primary TOV control equipment. Repeated faults caused by unsuccessful reclosing into a faulted line or other AC system component, however, shall be considered as individual fault events.
9.4 Temporary Overvoltage Limits
The Merchant Transmission Facility is not expected to cause unacceptable fundamental-frequency overvoltages on the interconnected 345kV transmission system.
Overvoltage duration shall be defined as the total cumulative period of time that the TOV envelope is at or above the given magnitude as a result of any single event or related sequence of events. This requirement shall be met for events and conditions including, but not limited to the following:
1. AC faults and fault recovery, including faults in the PJM transmission system, faults involving the Merchant Transmission Facility system itself, as well as faults in the NYISO AC transmission system;
2. Tripping radial AC circuits that tie the Merchant Transmission Facility to the PJM or NYISO transmission systems. This includes interruptions that only last for the dead time prior to automatic line reclosing, as well as lockouts for which the Merchant Transmission Facility can be shut down;
3. Events for which the Merchant Transmission Facility is tripped; and
4. Transformer energization.
The strategy for temporary overvoltage limitation must not limit post-disturbance AC reactive compensation capabilities to less than specified in Appendix G, Section 9.1. If reactive equipment tripping is used for TOV control, the equipment shall be available for re-energization in accordance with Appendix G, Section 6.7.3. If AC faults, on the Connecting Transmission Owner or PJM system reduce the AC voltage at either the POI or the 230kV PJM interconnection to a magnitude less than 50% of nominal positive sequence voltage for a duration longer than 100 ms this requirement shall not apply.
Any reactive power equipment tripping shall be performed using switchgear rated to perform the switching at the maximum voltage present prior to de-energization.
The HVDC converter may be used to control temporary overvoltages. If operation of the converter during and after disturbances is critical to meeting the temporary overvoltage specification, the Developer shall provide the following information:
1. Study results showing the temporary overvoltage performance considering direct current discontinuities which may occur, including those caused by distortion and mis-synchronization of valve firing following bolted AC faults at either converter.
2. Explanation and demonstration of temporary overvoltage performance for all cases where converters are to be blocked, including tripping of the PSE&G 230kV line in New Jersey, from which the AC connection to the converter station is made, converter faults, and DC cable faults; with due consideration of all telecommunication delays, signal processing times, relay operating times, and breaker operating times.
Failure of a single temporary overvoltage control equipment, including the Converter Station, shall not cause the overvoltage criteria to be exceeded.
Operation shall not be permitted without the Connecting Transmission Owner AC system protected from temporary overvoltages by a redundant overvoltage control scheme. This shall be interpreted as allowing power transfer with either or both the primary or backup temporary overvoltage control equipment unavailable, only up to the transfer for which the required reactive compensation cannot cause fundamental frequency overvoltage in excess of 1.05pu at the West 49th Street 345 kV Substation 345kV bus.
Overvoltage protective devices at the converter station and at the POI shall be coordinated with the overvoltage protective devices (surge arresters) installed such that overvoltages, caused by excess reactive power flow from the Merchant Transmission Facility system into the Connecting Transmission Owner AC power system, and switching transient overvoltages, caused by switching of reactive banks or switching of the Merchant Transmission Facility system itself shall not cause duty in excess of the capability of any existing surge arresters. Details of the existing surge arresters in the West 49th Street Substation will be obtained from Connecting Transmission Owner.
Insulation levels of the Merchant Transmission Facility shall include minimum margins above surge arrester protection levels as follows:
Developer shall provide to NYISO , PJM, and Connecting Transmission Owner the results of the insulation coordination study for review as specified in Appendix C, section 6(f). The study shall assure that the equipment as described in Appendix C, section 1(b)(4), the DAF and the West 49th Street Substation are properly insulated and that the insulation systems are properly coordinated. The study shall include the insulation coordination philosophy, the limiting cases, surge arrester currents for coordination purposes, equipment insulation levels, surge arrester locations, and the resulting protection margins.
