A generator owner may operate 60 Hertz, three phase or single phase generating equipment, in parallel with the borough’s system pursuant to an approved interconnection application provided that the equipment and generator owner meet or exceed the requirements of these guidelines and that the borough has approved the generator owner’s application to interconnect. This division (P) describes typical interconnection requirements. Certain specific interconnection locations and conditions may require the installations of additional protective settings or hardware, especially when exporting power to the system. If the borough, in the borough’s sole opinion, concludes that an application for parallel operation requires additional protective settings or hardware, the borough shall make those requirements known after all pertinent studies are completed.
(2) Approval to connect to the borough system indicates only that the minimum borough electrical requirements for a safe proper interconnection have been satisfied. Such approval does not imply that the generator owner’s facility meets land use, zoning, planning or federal, state and other borough standards or regulations.
(a) General interconnection and protection requirements.
1. The generator owner’s generation and interconnection installation must meet all borough land use, zoning, planning and applicable national, state and local construction and safety codes.
2. The generator owner’s generator shall be equipped with protective hardware and software designed to prevent the generator from energizing the borough’s de-energized circuits. The generator must automatically disconnect from the borough’s system if the grid source is lost, irrespectively of connected loads or other generators.
3. The generator shall be equipped with the necessary protective hardware and software designed to prevent sustained parallel operation of the generating equipment with the borough system unless the system service voltage and frequency are within acceptable magnitudes.
4. The generator owner will be responsible for protecting its own generating and interconnection equipment in such a manner so that borough system outages, short circuits, single phasing conditions or other disturbances including zero sequence currents and ferroresonant over-voltages do not damage the generator owner’s generating equipment. The protective equipment shall also prevent excessive or unnecessary tripping that would adversely affect the borough’s service reliability to other generator owners and customers.
5. The generator and interface protection schemes shall be continuously monitored and functioning and the generator shall immediately disconnect from the borough’s system for any condition that would make the protection scheme inoperable.
6. The operating power required for the protection and control schemes for the generator and the control power used to disconnect the generator from the borough must not be dependent on local borough power.
7. Where multiple generators are connected to the system through a single point of common coupling, the sum of the ratings of the generators will be used to determine the applicability of these guidelines. Protection scheme performance with one or more units off line will be considered.
8. Applicable circuit breakers or other interrupting devices at the generator owner’s facility must be capable of interrupting the maximum available fault current at the site, including any contribution from the owner’s generator(s).
9. The generator owner will furnish and install a manual disconnect switch which, when opened, will have the effect of isolating the generator from the borough’s system. The disconnect device shall have a visual break appropriate to the voltage level, and shall be mounted on the exterior of the building adjacent to the borough revenue meter accessible to the borough’s personnel at all times, and shall be capable of being locked in the open position via a borough padlock. The borough shall use reasonable efforts to utilize padlocks of a size consistent with typical manufacture’s specifications. The generator owner shall follow the borough’s switching, clearance and tagging procedures.
10. The design, procurement, installation and maintenance of the equipment at the generator owner’s site shall be the responsibility of the generator owner at the generator owner’s expense.
11. Any necessary enhancements or improvements needed, in the opinion of the borough, within the borough’s system and/or at the customer sites to accommodate the parallel interconnection of the generator owner’s generation will be at the generator owner’s expense.
12. The generator owner has full responsibility and liability for the safe and proper operation of their equipment and the power originating from their generator. The generator owner is also responsible for synchronizing their generator(s) with the borough’s system and maintaining a synchronous operation.
13. The generator owner must immediately cease parallel operation upon notification by the borough if such operation is determined to be unsafe, interferes with the supply of service to other customers, or interferes with the borough’s system maintenance or operation.
14. The borough reserves the right to specify the type of transformer connection that will be employed for all multiphase interface transformers consistent, where reasonable, with the generator owner’s power system.
(b) Prevention of generator owner generation interference with the borough system. To eliminate undesirable interference caused by operation of the generator owner’s generating equipment, the generator owner’s generator shall meet the following criteria.
1. Voltage. The generating equipment will be operated in such a manner that the voltage levels on the borough’s system are in the same range as if the generating equipment were not connected to the borough’s system. The generator owner shall provide an automatic method of initiating a disconnect sequence of his or her generating equipment from the borough system with set points noted in the table below.

b. The generator owner may reconnect to the grid when the system voltage returns to normal range and is stabilized as defined in the definitions.
2. Flicker. The generator equipment or operation of equipment shall not cause voltage flicker on the borough’s system or to any other borough customer. This flicker shall not exceed the borderline of irritation curve, as defined in IEEE Standard 519-1992, Recommended Practices and Requirements for Harmonic Control in Electric Power Systems. Lower levels of flicker may be required in areas where equipment such as computers and instrumentation are impacted.
3. Frequency.
a. The operating frequency of the generating equipment shall not deviate more than the values noted in the table below.
Generating Systems with Inverters up to 30 KW | Generating Systems with Inverters Greater than 30 KW | Non-Inverter or Rotating Machine Generating Systems |

b. The generator owner may reconnect when the system frequency returns to normal range and is stabilized.
4. Harmonics.
a. Non-linear circuit elements such as inverter can produce harmonics. Per IEEE Standard 519, Recommended Practices and Requirements for Harmonic Control in Electric Power Systems, the total harmonic distortion (THD) voltage shall not exceed 5% of the fundamental 60 Hz frequency nor 3% of the fundamental for any individual harmonic as measured at the location where the customer interfaces with the borough’s system (point of common coupling). In addition, the level of harmonic current that the customer is allowed to inject into the borough’s system shall not exceed that specified in IEEE Std 519. Furthermore, any communication notch shall be limited as defined by IEEE Std 519. The preceding requirements apply to all types of generation systems.
b. The generator owner is responsible for the installation of any necessary controls or hardware to limit the voltage and current harmonics generated by his or her equipment to defined levels.
5. Power factor.
a. The generator must not adversely impact the power factor of the generator owner site. Inverters shall be designed to operate close to unity power factor. The operating power factor of the generator shall be contained within the limits defined in the table below.
Generating Systems with Inverters up to 25 KW | Generating Systems with Inverters Greater than 25 KW | Non-Inverter or Rotating Machine Generating Systems |
0.85 lagging or leading when output exceeds 10% of inverter rating. (From IEEE 929-2000) | 0.85 lagging or leading when output exceeds 10% of inverter rating | 0.85 lagging or leading |
b. However, to the extent that a generator owner’s power factor at the point of common coupling falls below 0.985 lagging, the generator owner must obtain, install and maintain, at his or her expense, corrective apparatus that compensates for the drop in power factor caused by the installation of the generator.
6. Current.
a. In some cases, directional over-current protection may be required to limit fault current flowing onto the grid in the event of a line fault. DC inverters that are incapable of producing fault current do not require directional over-current protection.
b. Inverter systems shall not inject DC current greater than 0.5% of rated inverter output in the AC interface point under either normal or abnormal conditions.
7. Fault and line clearing. The generator owner shall automatically disconnect from the borough’s system during electrical faults on the borough’s electrical system and upon loss of the borough’s electric source. The generator owner may reconnect when the system voltage and frequency return to normal range and is stabilized. Detection of the loss of the borough’s primary electric system, where the generator owner is operating in an island with other customer load, becomes increasingly difficult as the level of dispersed generation on a feeder approaches the connected load. The over/under voltage and over/under frequency settings described previously along with the anti-islanding provisions of IEEE 929/UL 1746 inverters, shall be sufficient to satisfy this provision.
8. Automatic reclosing. The generator owner is responsible for protecting his or her equipment from the effects of switching or automatic reclosing of the borough’s feeder circuits.
(3) Control, protection and safety equipment requirements specific to generators of 25 KW or less. All generators 10 KW or less can be single phase. The following table describes necessary control, protection and safety equipment specific to generator of 25 KW or less connected to secondary or primary voltage systems:

(4) Control, protection and safety equipment requirements specific to three phase synchronous generators, induction generators, and inverter systems. Generators greater than 25 KW must be three phase machines connected to three phase circuits.
(a) Three phase synchronous generators. Generator circuit breakers shall be three-phase devices with electronic or electromechanical control. The generator owner is solely responsible for properly synchronizing his or her generator with the company’s system. For a synchronous generator, the excitation system response ratio shall not be less than 0.5. The generator’s excitation system(s) shall conform, as near as reasonably achievable, to the field voltage vs. time criteria specified in American National Standards Institute Standard C50.13-1989 in order to permit adequate field forcing during transient conditions.
(b) Three phase induction generators and inverter systems. Induction generation may be connected and brought up to synchronous speed (as an induction motor) if it can be demonstrated that the initial voltage drop measured on the company ‘s side at the point of common coupling is within the visible flicker limits. Otherwise, the generator owner may be required to install hardware or other techniques to bring voltage fluctuations to acceptable levels. Line-commutated inverters do not require synchronizing equipment. Self-commutated inverters whether of the utility-interactive type or stand-alone type shall be used in parallel with the company system only with synchronizing equipment.

Testing and testing intervals shall be in accordance with manufacturers’ and industry recommendations. Testing shall verify all protective set points and relay/breaker trip timing. The borough, at it discretion, may witness the testing of installed switchgear, protection systems, and generator. The generator owner is responsible for all maintenance of the generator, control and protective equipment. The generator owner will maintain records of such maintenance activities which the borough may review at reasonable times. Annual inspection of each generator installation shall be required at the discretion of the borough.
(9) Revenue metering. Revenue metering requirements will be reviewed on each specific installation. A single net meter shall be provided by the borough for each generator installation. The customer shall be responsible for all costs associated with the borough revenue metering.
