I. EXECUTIVE SUMMARY:

The Coordinated Electric System Interconnection Review (CESIR) is completed for the project described below. The objective of the CESIR Study is to review the proposed interconnection, specify and estimate the cost of the equipment, engineering, procurement and construction work (including overheads) needed to implement the interconnection.

The project has been determined to be viable for proposed project output 2,000 KW.

The project is required meet all the requirements as per this report.

PSEG Long Island’s total Interconnection Cost is estimated to be $97,556. (Note:

This is a very high level estimate and a more accurate estimate will conducted upon approval of the work in support of the project and said estimate will be revised accordingly as design details are developed. In addition please be advised that a 30% down payment will be due with agreement of this study plus progress payments thereafter during construction and any excess will reconciled and invoiced to the Applicant after COD)

II. PROJECT DESCRIPTION:

PSEG Long Island and the Project Applicant are presently engaged in the development of a Cogen project to deliver generation capability by interconnecting to the LIPA distribution system as follows:

Customer Proposed Interconnection: Interconnect with Existing Feeder, Project Information

App Number: PAM-2016-34610 Applicant: Northport VA Medical Center, Address: 79 Middleville Rd, Northport, NY 11768

KW: 2,000

Developer: Stantec Electric acct #: 618-99-2750-1 Grid: 045071779, Feeder: 6P-5H5, Substation: 6P

CESIR Report NVMC December 21, 2016 4

Northport VA Medical Center (NVMC) is a primary metered customer with two (2) 13.2kV LIPA circuit (6RL-765 and 6P-5H5) coming into customer main switchgear. Northport VA Medical Center is currently splitting the campus load into 6RL-765 (Elwood substation) and 6P- 5H5 (Pulaski Substation) feeder.

The interconnection of proposed project for 2MW Cogenerator in parallel with circuit 6P-5H5 would be viable if below requirements are met,

• NVMC campus load cannot be fed from one feeder without PSEG Long island’s permission.

• The two feeders (6RL-765 and 6P-5H5) can never be parallel.

• NVMC cannot switch circuit.

• Reconfigure of campus load such that the NVMC are fed by two circuit normally . The design intent to move one campus feeder, “D”, from Elwood to Pulaski to prevent export of the generation back to LIPA system and to maintain as balanced of a demand around 150 amps on both feeder (6RL-765 and 6P-5H5).

• The generator should only operate in parallel with feeder 6P-5H5 (Pulaski Substation) feeder. The design intent is to operate generator on circuit 6P-5H5 only.

• The generator shall not operate in parallel with LIPA system with circuit 6RL-765.

• When the plant generating equipment is operating in parallel with the LIPA system, it shall produce voltages at the point of interconnect within +/- 5% of 13.2 kV. The facility will automatically disconnect from the LIPA system within one (1) second if the voltage cannot be maintained within tolerances.

• The interconnected facility shall operate between .90 lagging and .90 leading power factor at all times. From time-to-time, the LIPA may request the unit to change its power factor if within these limits.

• The one line diagram is not approved for construction until for the protection requirements are met.

III. Engineering Design Standard and Specifications:

See attached document “PSEG-LI Smart Grid Small Generator Interconnection Screening Criteria for Operating in Parallel with LIPA’s Distribution System”.

IV. TECHNICAL COMMENTS ON THE MATERIALS AND INFORMATION

SUBMITTED WITH THE SGIP APPLICATION:

(Note Following comments are extensive as SGIP submittal documents. Accordingly, the comments must be addressed during preconstruction approval drawing submittals. )

1. Please refer to attached interconnection guideline for requirements called for in the LIPA interconnection guide

2. Identify the transformer winding/grounding configurations of the existing East and West Solar Arrays.

3. Operating Philosophy Note ‘d’ on drawing E-602 indicates that Elwood and Pulaski feeders will never parallel. Is this accomplished by a Procedural Control (i.e. – switching procedure) or an Engineering Control (i.e. – Kirk-key interlocks). Provide details of existing interlocking and any proposed changes due to new generator.

4. The generator is depicted as solidly grounded. A generator neutral reactor is normally used to limit the ground fault currents and protect the generator windings. Please confirm. We

CESIR Report NVMC December 21, 2016 5 have seen instances of developers solidly grounded generators getting damaged due to high fault currents. Developer should be aware of this risk and design for it.

5. If a generator neutral reactor is used then the ground source impedance must be selected so that the DG system remains effectively grounded (per IEEE C62.92.1-2000) when it is islanded with the LIPA 13kV distribution feeder breaker open. If this fails then 3V0 protection (59N) may be required. Results of the study need to be submitted and reviewed by Protection Engineering. (See attached LIPA interconnection guide)

6. The interconnect transformer is Wye-grounded/Wye-grounded. DG is required to perform a study to determine if their ground source contributes more than 400A (at 13kV) of ground fault current for a ground fault at the LIPA substation with the LIPA 13kV distribution breaker closed. Results of the study need to be submitted and reviewed by Protection Engineering. Harmonic requirements must also be met and tested. (See attached LIPA interconnection guide)

7. Provide separate DC schematics and 3-Line diagram that coordinate with One-Line Diagrams.

8. Show all CT ratios on One-Line Diagram E-601.

9. LIPA feeder circuit designations must be shown on One-Line Diagram E-601.

10. The project shall require both SCADA (Supervisory Control and Data Acquisition) RTU (Remote Terminal Unit) and a DTT (Direct Transfer Trip) system.

The DG System shall make provisions adjacent to the Supervisory control cabinet to terminate the supervisory control four (4) wire dedicated telephone lease line(s) on a double pole double throw open blade cut off switch(es) (Refer to attached diagram Appendix C). The lease line(s) shall be ordered by and owned by Customer. All cost for engineering and installation for lease line shall be the responsibility of the DG system owner. Installation, maintenance and subsequent monthly charges shall be the responsibility of the DG System owner.

SCADA RTU Requirements: The required RTU will be purchased, installed and configured by the customer. The DG System shall not be allowed to operate in parallel if the RTU or its associated lease line is out of service.

The SCADA RTU must use DNP 3.0 protocol. Our general requirement for the SCADA line is: IEEE Type 3, SPO Class B characteristics, 16 dB attenuation, basic conditioning, 4 wire, Full duplex, non-critical circuit. Frequencies 300-3000 Hz, Max. Tx. Level (Tot.Pwr)/Time Duration -3dB. It should be an Enterprise 46PRNA type circuit. The Hicksville operations center demark for the circuit must be at the Newbridge 3624 Node. The developer will need to install a Telenetics DSP9612LV Flash poll modem at their site. RTU Points Count. There will be total of 9 points, 1 digital and 8 analog. Digital points will be: Interconnection Breaker Status. Analog points will be: A phase amps, B phase amps, C phase amps, A phase voltage, B phase voltage, C phase voltage, WATTS and VARS. In our applications we typically utilize Telenetics DSP9612LV Flashpoll modem. PSEGLI will provide RTU programming sheet (Function Tab).

CESIR Report NVMC December 21, 2016 6

All costs for additional hardware and software for LIPA's mainframe Supervisory computer that are required for its interconnection shall be charged to the DG System. All future maintenance, maintenance costs and replacement costs of RTU is by the DG system owner.

DTT Requirements: The direct transfer trip (DTT) receiving terminal shall provide two outputs: a trip output and an alarm output to indicate a loss of transfer trip condition. The trip output shall energize a utility type target relay with multiple output contacts. One (1) output contact of the target relay shall trip the interconnection breaker. A second output contact of the target relay and the alarm contact of the DTT terminal shall be wired to the DG’s SCADA system. The alarm for the loss of a DTT lease line must come from the DG’s SCADA sys tem or by having bi-directional tone equipment that can indicate the alarm at the LIPA substation.

For DTT equipment the developer needs to order the DTT equipment that will be installed at their substation. An RFL-9745 is the LIPA standard equipment used to automatically trip interconnection breaker whenever LIPA substation breaker opens. This is the description for use with an Analog Lease Line: The RFL-9745 Logic diagram should be CD46180.

RFL MODEL 9745, PART # TSHN655000, TELEPROTECTION CHANNEL WITH 4-

TONE AUDIO INTERFACE, 38-150 VDC POWER SUPPLY, FRONT DOOR WITH

TEST PANEL AND ONE 48/125 VDC RELAY/SS TERMINAL BLOCK I/O BOARD.

The DTT terminal and associated target relay shall be mounted indoors.

PSEGLI will order one and be paid for by developer and installed at our substation. The following is information for Verizon analog lease line for DTT with RFL-9745. One four-wire, full duplex lease line IEEE type 4 with Class A protection and no repeaters.

11. Once drawing comments have all been addressed, developer will have to submit relay settings file (.RDB or .MDB file format for SEL relays), relay settings summary sheet, protection system test plan and final test report for review prior to energization. Relay settings summary sheet will provide set points for various protection elements. Protection system test plan must provide details on tests that will be performed on DC circuitry, AC circuitry and relay logic. Final relay protection test report will be based on test plan and relay acceptance testing. Developer’s equipment can be energized via LIPA feeder after review of these documents is completed. We generally look for the following documentation and information:

-Acceptance testing of relay’s protection elements. All pick-ups and operating times.

-Relay serial # and part #.

-Relay visual and mechanical inspection -Trip tests. Test that all wired output contacts of all relays perform their intended function. Test that output contacts intended to trip the breaker perform this function.

-Test that breaker is tripped when relay goes into alarm.

-Test that breaker is locked out when tripped by a protection function.

-Perform load checks.

12. A battery/UPS is required to be used to power the relay. The LIPA interconnection guide requires an 8 hour duty cycle in accordance with IEEE standard 485-1983. At the end of the duty cycle the battery shall be capable of tripping and closing all breakers. The developer should provide a spec sheet and maintenance procedure for the system expected to be used in this application.

CESIR Report NVMC December 21, 2016 7

13. Redundant Protective Relays are required unless the interconnect breaker is tripped when the relay alarms.

14. Lockout function (86) must be shown on functional whether internal to relay or an external separate relay is used.

15. Fuse sizes should be on drawings.

16. Transformer differential relaying is required for interconnections using transformer banks greater than 1500 kVA.

17. The Developer is running DTT into an Ethernet Switch. In the event any of this hardware fails/goes into alarm, it must trip the generator breaker.

18. Rearranging the on-campus load to better work with their Cogen output (2MW

Cogen, moving one campus feeder, “D”, from Elwood to Pulaski) and our peak load restrictions (no more than 150 amps on either feed during normal operation)

19. Existing Metering shall remain. The meter will be detentive meter.

20. Generator shall have outdoor Cogen Disconnect with 24/7 access to PSEG Island.

Refer to SGIP document Section II. E. Disconnect Switch for requirements.

21. Systems greater than 25 kW that do not utilize inverter based interface equipment shall not have automatic recloser capability unless otherwise approved by PSEG Long Island. PSEG-Long Island could approve a NYS type tested and approved device similar to Beckwith 3410A that will “re-parallel” after 5 minutes of restored proper utility voltage and frequency. The equipment shall meet the requirements in accordance with IEEE Std 1547.

V. GENERAL REQUIREMENTS:

The New York State Department of Labor has enacted rules for notification when an excavator plans to use mechanical equipment on public or private property.

Pursuant to Industrial Code Rule 53, which became effective April 1, 1975, the excavator must notify each operator of existing underground facilities (such as Verizon, Water Co., etc.) that are within 15 feet of the proposed work area. This notice must be given within 10 days prior to the planned date of excavation so that facilities can be marked in the field to avoid damage.

You are being advised that LIPA must comply with these requirements and you should take into account the additional lead time this procedure will take in order to meet your service need date.

To notify both LIPA and Verizon for mark out of underground facilities or if you require further information regarding "Rule 53", please call (800) 272-4480.
