1.0 General
This document standardizes the technical requirements for interconnection of
Distributed Generation ( DG ) equipment to PSE&G Distribution facilities in all
sizes to 5000 KW. In addition, this document also contains a standardized
application process and a standardized interconnection license for facilities
with distributed generation.
This document deals with various modes of Distributed Generation operation:
Simple load offset systems without export capability.
Load offset systems with partial export capability.
Pure merchant installations with full export capability.
Generation not operating in parallel, i.e. isolated from PSE&G grid, is not
subject to these requirements.
2.0 Scope
This set of interconnection requirements defines the application process,
technical interconnection requirements and license elements for
interconnecting new distributed generation facilities to Primary Distribution
Circuits and to Customer Secondary Services.
1
This document addresses
only those points in which the customer, developer, operator, equipment
manufacturer and the utilities have a mutual interest and is primarily directed
toward the safety aspects of the interconnected distributed generator. This
document also provides for an expedited / streamlined approval process for
small Distributed Resources (less than 100 KW) that utilize Solar
Photovoltaic or Wind Technology and qualify for Net Metering under Section
38-e-1&2 of the New Jersey "Electric Discount and Energy Competition Act"
for rate classes RS - Residential Service and GLP General Power and
Light (See Step 1A on Page 6).
If the Applicant is proposing the interconnection of equipment that would
normally qualify under the Net Metering program but the tariffed service is
not RS or GLP, PSE&G will permit the filing of the expedited application form
(Appendix B) and will waive the Insurance Requirements described in
Section 5.0.
The Distributed Generator may also need to get approval from other entities,
including but not limited to the PJM Interconnection, NJ Department of
Environmental Protection (NJDEP), and the Federal Energy Regulatory
Commission (FERC) depending on size and power export plan. This document
does not address the policies and procedures of any organization outside of
PSE&G.

3.0 Application Process
Key Steps in the Application Process for the Interconnection of New
Distributed Generation Connected to Primary Distribution Circuits and to
Customer Secondary Services Operating in Parallel with the PSE&G Grid
(General Guidelines)
Introduction
This section outlines a framework for processing interconnection applications
and ensuring that applicants are aware of the PSE&G Standardized
Interconnection Requirements (SIR), as described in Section 5. This section
Provides applicants with an understanding of the process and information
required to permit PSE&G to review and accept the applicants equipment for
interconnection in a reasonable and expeditious manner.
The time required to complete the process will reflect the complexity of the
proposed project. Projects using previously submitted designs that have been
satisfactorily Type tested
2
will move through the process more quickly, and
several steps may be satisfied with an initial application depending on the
detail, completeness of the application, and supporting documentation
submitted by the applicant. Applicants submitting Type tested systems,
however, are not exempt from providing PSE&G with a complete design
package necessary to verify the electrical characteristics of the generator
system, the interconnecting device, and the impacts of the applicants
equipment on the utilities systems.
The application process and associated services are offered by PSE&G on a
non-discriminatory basis. The applicant is responsible for those costs that
PSE&G would not have incurred but for the applicants interconnections.
Application Process
STEP 1 - Initial Communication From the Applicant.
Communication will range from a general inquiry to a completed
application. The applicant should supply as much technical information
as possible. At this point in the application process PSE&G shall make
the determination on whether the proposed installation is an application
for State of New Jersey Qualified Net Metering (See Section 4.2.1 and
STEP 1A) or is an application for a conventional form of Distributed
Generation. If the Applicants proposed unit is not a State of New Jersey

2
See Glossary for definition. 5
Qualified Net Metering unit of 100 KW or less and it is the intention of the
applicant to export power or to sell power to PSE&G under an existing
tariff, then the Non-Utility Generation Group shall also review the
application.
Applications for small residential, commercial or industrial distributed
generation systems less than 100 KW shall strictly adhere to the
requirements outlined in the National Electrical Code NFPA-70-1999, list
all proposed equipment and for Non Net Metering Qualified Systems
also include an interconnection diagram signed and sealed by a
licensed New Jersey Electrical Contractor.
Applications for all commercial or industrial distributed generation
systems greater than 100 KW shall strictly adhere to the requirements
outlined in the National Electrical Code NFPA-70-1999, where
applicable, the National Electrical Safety Code IEEE C2-2002, include a
listing of all proposed equipment and include a one line control /
interconnection diagram signed and sealed by a licensed New Jersey
Professional Engineer.
STEP 1A Expedited Application Process for Qualified Net Metering
Installations 100 KW or Less.
1) Prior to installation of a qualified net metered system (100 kW or less),
applicants must submit a fully completed first page of the Net Metering
Application (see Appendix B) to PSE&G, with the $100 application fee,
to the address noted on the application.
2) After PSE&G receives the completed application and conducts the
appropriate review, it will inform the applicant if it can proceed with the
interconnection, or if a more detailed interconnection study is required
(see Step 4 below).
3) After the applicant has received permission to interconnect from PSE&G,
has completed the installation and has received the appropriate municipal
inspection, the applicant must submit a fully completed and signed
application
(all pages) to PSE&G. This application must include the signature of the
local'
inspection official, or a copy of the approved municipal inspection certificate.
4) The following sections apply to Net Metering 100 KW or less installations:
a) 4.2
Metering
b) 4.2.1
Net Metering
c) 4.3 Grounding
d) 4.6 Disconnect switch or device 6
e) 4.7
Power Quality
f) 4.10.1 A Compliance with IEEE 929-2000
g) 4.10.2
Verification Testing
h) 4.12
Connections to Network Systems
STEP 2 - The Inquiry is Reviewed by PSE&G to Determine the Nature of the
Project.
A PSE&G representative shall discuss the scope of the project with the
potential applicant (either by phone or in person) to determine what
specific information and documents (such as an application, license,
technical requirements, specifications, listing of qualified Type tested
equipment/systems, application fee information, applicable rate
schedules and metering requirements) will be required by the applicant.
The preliminary technical feasibility of the project at the proposed
location may also be discussed at this time. All such information, and a
copy of this application, will be sent to the applicant in no more than five
(5) business days following the initial communication from the
