The purpose of these Operating Instructions is to provide for the coordinated parallel operation of the Long Island Power Authority’s (LIPA) system through LIPA’s agent, Long Island Electric Utility Servco LLC (“T&D Manager”) and NORTHPORT VA MEDICAL CENTER whose facilities are located at 79 Middleville Rd, Northport, NY 11768 operated and maintained by NORTHPORT VA MEDICAL CENTER, as provided for in the Interconnection Agreement (IA) dated April 04, 2016. If these Instructions conflict with the IA, IA prevails, LIPA reserves the right to modify these Operating Instructions from time-to-time, upon reasonable prior notice to NORTHPORT VA MEDICAL CENTER, as may be required in response to any changes in LIPA's Electric Operating Procedure.

ARTICLE II — OPERATING PROCEDURES

The Distribution System Operator (DSO) of Long Island Electric Utility Servco LLC as agent for and acting on behalf of Long Island Lighting Company d/b/a LIPA’s distribution system connecting the NORTHPORT VA MEDICAL CENTER Photovoltaic system with the LIPA system. Any communication concerning the operation of the related electric system should be with the DSO (Eastern Suffolk). The telephone number of the DSO is 631-233-8216. This number is available on a 24-hour basis.

The NORTHPORT VA MEDICAL CENTER Cogen Facility, the operators of the generation, is responsible for the operation of the associated electrical equipment. Any communication relative to the operation and/or access of that system should be made with NORTHPORT VA MEDICAL CENTER personnel at the telephone numbers in Appendix I. These contact telephone numbers are to be available on a 24-hour basis.

NORTHPORT VA MEDICAL CENTER shall adhere to all LIPA & T&D Manager’s safety and clearance procedures in accordance with Appendix V, when working on LIPA premises.

ARTICLE III – INTERCONNECTION

NORTHPORT VA MEDICAL CENTER is a primary metered customer with two (2) 13kV circuit feeds (6RL-765 and 6P-5H5) coming into their existing and new outdoor switchgears. The Cogeneration system shall only operate in parallel with feeder 6P-5H5. If the generation facility is disconnected as a result of the operation of a protective device, the generator-owner’s equipment shall remain disconnected until LIPA’s service voltage and frequency have recovered to acceptable voltage and frequency limits for a minimum of five (5) minutes. The generator needs manual restart if generator breaker is tripped.

The interconnected facility contains 2000 kW AC Cogen system. The facility is interconnected to a

13.2 KV LIPA distribution feeder 6P-5H5. The interconnection includes customer owned primary cable from the primary meter (detented meter) to the new Primary metering enclosures and customer owned new switchgear house, there is also a 2500kva customer owned transformer.

The system includes a SEL 351-A relay and a SEL-700 generator protection relay. The line of demarcation of operating responsibility is as shown on the attached one-line diagram (Appendix II).

A utility disconnect switch has been installed, to provide LIPA with a disconnect point from feeder 6P-5H5.

ARTICLE IV - MAINTENANCE OF INTERCONNECTION AND RELATED FACILITIES

The attached "Ownership and Responsibility Matrix", Appendix IV, indicates the party responsible for making repairs to equipment and who will incur cost of necessary repairs.

ARTICLE V — LIPA REVENUE METER ACCURACY

LIPA will maintain the electric metering equipment in accordance with prudent electric utility practice.

ARTICLE VI - MAINTENANCE PROPER VOLTAGE AND FREQUENCY

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 clearing times provided below.

The interrupting device shall automatically initiate a disconnect sequence from the LIPA system within time specified in table below if the voltage or frequency are in specified range.

Under- and over-voltage trip functions, implemented by utility-grade relays, shall be provided by three (3) single phase voltage elements in the relay. The PT’s shall be connected phase to ground to perform these functions.

Under- and over-voltage trip functions, as specified in IEEE 1547, shall be set with the following thresholds and such as to achieve the following clearing times (The clearing time is the time between the start of the abnormal condition and the DER System ceasing to energize the LIPA system - interrupting device operating time plus relay time):

Voltage Range (% of base voltage)

Clearing Time (seconds)

Clearing Time

(cycles) V ≤ 50 0.16 9.6 V ≤ 88 5.0 300 V ≥ 110 1.0 60 V ≥ 120 0.16 9.6

Under- and over-frequency trip functions, as specified in IEEE 1547, shall be set with the following thresholds and such as to achieve the following clearing times (The clearing time is the time between the start of the abnormal condition and the DER System ceasing to energize the LIPA system - interrupting device operating time plus relay time):

Frequency Range Hz

Clearing Time (seconds)

Clearing Time

(cycles) f ≤ 56.5* 0.16 9.6 f ≤ 58.0* 180 10800 f ≥ 61.0 180 10800 f ≥ 62.0 0.16 9.6

* The under frequency setting is a recommended setting based on NERC standard PRC-006- NPCC-1 Automatic Under frequency Load Shedding curve Figure 1.

ARTICLE VII - REAL AND REACTIVE POWER REQUIREMENTS

The interconnected facility shall operate between .90 lagging and .90 leading power factors at all times. For circumstances when the Cogen output goes beyond 126 V or below 122 volts the CHP system should have the settings to modify the power factor to maintain operation.

Over time we will monitor operation to ensure proper voltage and adjust as may be needed. From time-to-time, the LIPA DSO may request the unit to change its power factor between the limits of .90 lagging and .90 leading power factors.

ARTICLE VIII- MAINTENANCE PROCEDURES

NORTHPORT VA MEDICAL CENTER personnel shall conform to the following procedures in the event of scheduled maintenance. The attached “Ownership and responsibility Matrix”, Appendix III, indicates the party responsible for repairs to equipment and the associated costs of these repairs. During an unscheduled maintenance, DTT signal from LIPA will trip the interconnection breaker at the customer site to deenergize the producer’s generation. Please see below for unscheduled maintenance.

A. UNSCHEDULED MAINTENANCE

1. The producer's protection and interconnection equipment shall be designed and maintained to automatically disconnect the producer's generation from LIPA's system in the event that the portion of LIPA's system that interconnects with the producer's facilities is de-energized, regardless of the duration.

2. The producer's protection and interconnection equipment shall be designed and maintained to automatically disconnect the producer's generation from LIPA's system if an equipment failure or other condition on the producer's equipment occurs, that would create a condition that has a significant potential to:

A. Result in a disruption of the operation of LIPA's system.

B. Result in a disruption of service to other LIPA customers.

C. Endanger life or property.

3. LIPA may, without prior notification, disconnect the producer's generation from

LIPA's system in the event of:

A. A LIPA system emergency or pre-emergency.

B. Where it is deemed necessary by LIPA to insure the safety of the general public, LIPA’s and T&D Manager’s employees, or the integrity of LIPA’s system. T&D Manager will notify the producer as quickly as possible, the expected duration of such disconnection.

4. LIPA may, upon reasonable prior notice, disconnect the producer’s generation from

LIPA’s system in the event of:

A. A need to de-energize LIPA system (or portion thereof) to permit work on the system.

B. Failure of the producer to fulfill any design, operation, or maintenance responsibilities required to insure satisfactory parallel operation.

C. Evidence of interference of the producer's generation system with the quality of service rendered by LIPA to its customers.

D. NORTHPORT VA MEDICAL CENTER Facility shall not be allowed to operate in parallel with the LIPA system in the event that the DTT and/or SCADA system is inoperable due to equipment or lease line failure(s).

B. SEQUENCE OF EVENTS DURING MAINTENANCE, REPAIR OR EMERGENCY

NORTHPORT VA MEDICAL CENTER’s Cogen system is currently connected to a LIPA distribution feeder. In case of a maintenance, repair, or emergency event, LIPA/T&D Manager will either trip the Feeder automatically or request NORTHPORT VA MEDICAL CENTER to trip the Cogen system. NORTHPORT VA MEDICAL CENTER should request the approval from Distribution System Operator (DSO) to re-energize Cogen system.

In the event that the interconnection is separated/disconnected for any reason, the NORTHPORT VA MEDICAL CENTER will immediately notify the Distribution System Operator (DSO) of the separation/disconnection, its cause and expected duration, if available.

Under no circumstances will NORTHPORT VA MEDICAL CENTER re-establish, or attempt to re-establish/ re-energize the interconnection system until approval to do so has been obtained from the Distribution System Operator (DSO). Failure to do will constitute grounds for termination of the IA.
