AVAILABILITY
This rider is available to customers served under the following service classifications, Residential “R”, Small
Commercial “C and C1”, Medium Commercial “C2 and C3", Large Commercial “C5", Primary “P”, and
Transmission “T” who own and operate an electric generation facility on the Customer’s premises. The primary
intent of this installation is to offset part or all of the Customer’s electricity requirements. Capacity cannot be
more than 25 kW for residential customers and 500 kW for non-residential customers. The primary source of fuel
must be solar, wind, hydro, or another approved source of renewable energy. This rider is applicable to
generation interconnected and operated in parallel with the City of Dover’s transmission and/or distribution
facilities. Application for the installation of any generation system in excess of 500 kilowatts shall be made under
a special contract.
Any customer who elects this rider must apply by filling out the City of Dover Generator Interconnection
Application at least 60 days in advance of the proposed activation date. Approval of the application by the City
must be granted prior to activation of the electric generation facility.
CONNECTION TO THE CITY’S SYSTEM
The electric generation system cannot be connected to the City’s system unless it meets all applicable safety
and performance standards set forth by the following: The City of Dover Technical Considerations Covering
Parallel Operations of Customer Owned Generation of 500 kW or less dated July 1, 2008, National Electric
Code, the Institute of Electrical and Electronic Engineers, Underwriters Laboratories, and the City of Dover
Electric Service Handbook. The Customer must, at his/her expense, obtain any and all necessary permits,
inspections, and approvals required by any local public authorities and any other governing regulations in effect
at that time.
DELIVERED VOLTAGE
The delivered voltage and delivery point of the Customer’s electric generation shall be at the same delivered
voltage and delivery point that would be supplied by the City if the Customer purchased all of its electricity from
the City.
CONTRACT TERM
The contract term shall be the same as the Customer’s applicable rate tariff.
RATE
The monthly billing shall be as stated in the applicable rate tariff. Under this rider, only the per kWh charge for
electricity delivered by the Customer is affected. The Customer will pay for all kWh delivered by the City of
Dover. If the Customer has delivered electricity to the City’s system a credit will be issued equal to the City’s
current kWh rate for that particular class of customer (equal to the Delivery Service Charges and Supply Service
Charges). This credit will be applied to subsequent billing periods to offset a customer’s consumption (City
delivered kWh) in those billing periods until all credits are used or until the end of a twelve month period. After a
12 month period ending either on December 31 or July 31, to be chosen at the discretion of the customer, any
excess kWh credits shall be forfeited to the City for use solely to augment existing funding for the Green Energy
Fund. The payment to the Green Energy Fund shall be equal to the avoided cost of wholesale power. Any
excess kWh credits from the customer shall not reduce any fixed monthly customer charges, taxes or
other components of the electric bill imposed by the City.
METERING
Paj 34
City of Dover Effective July 1, 2008
Electric Tariffs
A bi-directional watt-hour electric meter will be installed at the Customer’s location to measure the energy
consumed and the energy delivered to the City system. The City will furnish, install, maintain, and own all bi-
directional revenue meters. However, where a large capacity meter is required to serve a customer, or a larger
capacity meter is requested by the customer, the customer shall pay the City the difference between the larger
capacity meter and the meter normally provided under the customer’s applicable rate tariff. Cost will be
determined under the Additional Costs and Responsibilities clause below.
ADDITIONAL COSTS AND RESPONSIBILITIES
The customer will be required to pay for any additional transmission and distribution costs, transformation,
system protection, and any related safety/protective equipment in excess of what would normally be paid for by
the City. Protective equipment will be installed by the Customer to provide safety for personnel, provide
adequate protection for the City’s electric utility system and to the Customer’s property, and to prevent any
interference with the City’s supply of energy to other utility customers. This equipment will be owned, installed,
and maintained by the Customer.
FAILURE TO COMPLY
The City may disconnect the Customers service from the City’s electric system if the Customer fails to comply
with any of the stipulations of this rider, The Technical Considerations Covering Parallel Operations of Customer
Owned Generation of 500 kW or Less dated July 1, 2008, National Electric Code, the Institute of Electrical and
Electronic Engineers, Underwriters Laboratories, the Generator Interconnection Application and the City of

subsequent approved revision thereof.
H. Interconnection – the physical connection of distributed generation to the
Company’s system in accordance with these guidelines so that parallel operation
can occur.
I. Interconnection Application - the standard form of application which must be
submitted by the Generation Owner to the Company for permission to
interconnect with the Company system. The approved Interconnection
Application sets forth the contractual conditions under which the Company and
Generator Owner agree that one or more generating units whose aggregate
generation at the Point of Common Coupling is less than or equal to 500 kW may
be interconnected at 34.5 kV or less with the Company’s system.
J. Inverter – a static power converter with control, protection and filtering functions

transfer of electric power between the Generator Owner and the Company System
takes place (such as switchgear near the meter).
N. Pre-Approved Equipment - specific generating and protective equipment
system or systems that have been approved by the Company as meeting the
applicable parts of this document.
O. Pre-Interconnection Study - a study or studies which may be undertaken by the
Company in response to its receipt of a completed application for parallel
operation with the Company’s system submitted on the Interconnected
Application form prescribed by these guidelines. Pre-Interconnection Studies
may include, but are not limited to service studies, coordination studies and
facilities impact studies.
P. Qualifying Facility (QF) - an electric generation facility which is a qualifying
facility under Subpart B, Section 201 of the Federal Energy Regulatory
Commission’s regulations per the Public Utility Regulatory Policies Act of 1978.
Q. Stabilized - the Company’s system following a disturbance which returns to the
normal range of voltage and frequency for at least 5 minutes or longer as
coordinated with the Company. The Company may require a longer period upon
a reasonable showing that the reconnection after 5 minutes will adversely affect
the safety and reliability of the electric system.
R. Unit – a distributed generation facility.
S. Utility System or Electric Distribution Facility - Company’s distribution
system operating at 34.5 kilovolts or below to which the generation equipment is
interconnected.
IV Interconnection Application - A proposed Generator Owner will make a formal
application to the Company for the interconnection of a generator to the Company system. The
application will be made on an Application Form provided by the Company.
V Designation of Company Contact Persons for Matters Relating to Distributed
Generation Interconnection – The Company’s Electric Engineering Department will be the
designated point of contact for all matters related to interconnected generation. The Company
will maintain records concerning applications received for interconnection and parallel operation
of distributed generation. Such records will include the date of receipt of each such application,
documents generated in the course of processing such applications, correspondence regarding
such applications and the final disposition of such application.
VI Pre-Interconnection Studies – In many instances the Company will wish to conduct a
service study, coordination study, or facilities impact study prior to interconnection of a
distributed generation unit. In instances where such studies are deemed necessary the scope of
such studies shall be based on the characteristics of the particular distributed generation unit to
be interconnected and the proposed point of interconnection.
A) Completion of Pre-interconnection Study - Upon completion of the
interconnection study, the Company will notify the Generator Owner that his
application has been approved or indicate insufficient detail why the application
Paj 38
cannot be approved. The conducting of such pre-interconnection studies shall not
unduly delay the interconnection of the distributed generation. In no event shall
such studies take longer to complete than 4 weeks after receipt of signed customer
application and customer submittal of all required data.
B) Pre-interconnection Study Fee - The Company will do a pre-interconnection
study without charge up to the typical and customary cost that the Company
would expend for study work of similar type of customer interconnection. If the
cost to the Company is expected to exceed this typical and customary amount, or
if multiple submittals by the Generator Owner are necessary, the Company will
advise the Generator Owner of the expected cost of such study work by the
Company before such work begins. The Generator Owner will be responsible for
payment of all costs above the typical and customary amount.
VII Network Interconnection of Distributed Generation – Where generation is to be
connected to a network system and capable of exporting power to the Grid, the interconnection
study may result in more stringent interconnection requirements.
VIII Pre-approval of Generation units, Devices and Systems - Upon approval by the
Company that certain generating unit’s protective devices and/or system(s) meet the standards
set out in these guidelines, such approval shall be made available to the appropriate manufacturer
upon written request. For subsequent applications using some or all of the identical generating
unit’s protective devices and/or systems, the manufacturer may submit a copy of the approval
with the application as proof that its equipment has already been approved for use on the
Company’s system. Use of pre-approved equipment will not eliminate any applicable
requirement for a pre-interconnection study to determine the suitability of the equipment for each
application, given the unique arrangements and characteristics of both the Generator Owner and
Company systems at the point of the interconnection.
IX Connection Approval – The Generator Owner can connect their generation to the
Company system only after the Interconnection Application has been approved and the
Generation Owner has received approval notification. The Company will provide notification
within four weeks after the receipt of the Interconnection Application and all required data.
X Interconnected Generation Site Warning Label – The Generator Owner will install a
warning label in a conspicuous place on their electric meter or meter box to notify the Company
personnel that there is a generator source installed on the load side of the meter. The warning
label shall not be placed in a location that would interfere with the ability of Company personnel
to read the electric meter. The Company will provide the warning label to the Generator Owner.
The warning label must be placed before the generation can be interconnected.
XI Disconnection and Reconnection.
The Company may disconnect a distributed generation unit under the following conditions:
1) Application Termination – Upon termination of the approved Interconnection
Application.
2) Non Compliance – For non-compliance with the technical guidelines specified in
this document or other requirements contained in the applicable Customer Tariff,
provided that the Company has given notice to the Generator Owner and provided
Paj 39
the Generator Owner reasonable time (consistent with the condition) to correct
such non-compliance. The Company will reconnect the unit only upon receipt of
certification from the Generator Owner and verification by the Company that the
unit is in compliance. The Company will provide verification within a reasonable
time period.
3) In Case of a system emergency outage of the Company’s Primary Electrical
Sources – The Generator Owner’s generation equipment must be installed and
configured so that parallel operation must automatically cease immediately and
automatically during outages or loss of the Company’s electric source in
accordance with these guidelines. The Generation Owner must also cease parallel
operation upon notification by the Company of a system emergency, abnormal
condition or in cases where such operation is determined to be unsafe, interferes
with the supply of service to other customers or interferes with the Company’s
system maintenance or operation. In addition, the Company may disconnect the
generator from the system for system emergencies without notice. However, the
Company will use reasonable efforts to notify the Generation Owner prior to
disconnecting.
4) For Routine Maintenance and Repairs – The Company may disconnect a
Customer/Generation Owner for routine maintenance and repairs on the
Company’s system consistent with applicable tariffs and agreements. The
Company will make reasonable efforts to provide advance notice to the
Customer/Generation Owner of service interruptions resulting from routine
maintenance.
The Company will reconnect the Customer/Generation Owner as quickly as
possible under reasonable operations constraints following any such service
interruption.
XII Termination – The Generation Owner may terminate the approved Interconnection
Application at any time upon thirty (30) days of providing written notice to the Company.
The Company may terminate the Interconnection Application for cause after 60 days
written notice to the Generator Owner of a material violation of the terms of the approved
Interconnection Application and after the Generator Owner has had a reasonable
opportunity to remedy the violation. The Generator Owner must give the Company notice
that it intents to permanently shut down his generation.
XIII Privileged Communications Concerning Proposed Distributed Generation Projects
– In the course of processing applications for parallel operation and in the conduct of pre-
interconnection studies, the Generation Owner shall provide the Company with detailed
information concerning the proposed distributed generation project. The Company shall
not use such knowledge of proposed distributed generator projects submitted to it for
review to prepare competing proposals to the Generator Owner whereby the Company, or
its affiliate, offers either discounted rates in return for not installing the distributed
generation, or offers competing distributed generation projects.
XIV Technical Guidelines for Parallel Operation of On-site Distributed Generation Units
– This subsection describes minimum requirements and procedures for safe and effective
connection and operation of distributed generation. A Generator Owner may operate 60
Hertz, three phase or single phase generating equipment, whether a QF or non-QF, in
Paj 40
parallel with the Company’s system pursuant to an approved Interconnection Application
provided that the equipment and Generator Owner meet or exceed the requirements of
these guidelines or the NEM Rider Tariff requirements and that the Company has
approved the Generator Owner’s application to interconnect. This subsection describes
typical interconnection requirements. Certain specific interconnection locations and
conditions may require the installation of additional protective hardware or special
protection settings, especially when exporting power to the system. If the Company
excludes that an application for parallel operation requires additional protective hardware
or special protection settings, the Company shall make those requirements known to the
Generator Owner within 14 days after all pertinent studies are completed.
Approval to connect to the Company system indicates only that the minimum
requirements for a safe proper interconnection have been satisfied. Such approval does
not imply that the Generator Owner’s facility meets all federal, state and local standards
or regulations.
A) General Interconnection and Protection Requirements.
1) The Generator Owner’s generation and interconnection installation must meet all
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 one of the Company’s
de-energized circuits. The Generator Owner’s generator must automatically
disconnect from the Company’s system if the Grid source is lost, irrespectively of
connect 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 Company’s system unless the system service voltage and
frequency are within acceptable magnitudes as defined in Section XIV.B.
4) Pre-approved equipment shall be accepted as part of an interconnection proposal
without the need to re-review the equipment itself. However, the application,
design and setting of pre-approved units and/or equipment must be reviewed and
coordinated according to the unique needs of the specific location of the proposed
installation. Where a complete unit or system has been pre-approved, only
location-specific issues will typically need to be reviewed.
5) The Generator Owner will be responsible for protecting its own generating and
interconnection equipment in such a manner so that Company 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 Company’s
service reliability to other Generator Owners and Customers.
6) The generator and interface protection schemes shall be continuously monitored
and functioning and the generator shall immediately disconnect from the
Company’s system for any condition that would make the protection scheme
inoperable.
Paj 41
7) The operating power required for the protection and control schemes for the
generator and the control power used to disconnect the generator from the
Company must not be dependent on local Company grid power.
8) 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 have to be considered.
9) Applicable circuit breakers or other interrupting devices at the Generator Owner’s
facility must be capable of interrupting the maximum available local utility
Company fault current at the site, including any contribution from the Owner’s
generator(s).
10) The Generator Owner will furnish and install a manual disconnect device which,
when opened, will have the effect of isolating the generator from the Company’s
system. The disconnect device shall have a visible break (a disconnect switch, a
draw-out circuit breaker, fuse block, etc. as appropriate to the voltage level), will
at all times be accessible to the Company’s personnel, and shall be capable of
being locked in the open position via a Company padlock. The Company shall use
reasonable efforts to utilize padlocks of a size consistent with typical
manufacture’s specifications. The Generator Owner shall follow the Company’s
switching, clearance and tagging procedures which the Company shall provide
and attach the Warning Label noted in Section X.
11) The design, procurement, installation, and maintenance of the equipment at the
Generator Owner’s site are the responsibility of the Generator Owner and at the
Generator Owner’s expense.
12) Any necessary enhancements or improvements needed within the Company’s
system and/or at the Customer site(s) to accommodate the parallel interconnection
of the Generator Owner’s generation will be at the Generator Owner’s expense.
13) 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
Company’s system and maintaining synchronous operation.
14) The Generator Owner must immediately cease parallel operation upon
notification by the Company if such operation is determined to be unsafe,
interferes with the supply of service to other customers, or interferes with the
Company’s system maintenance or operation.
15) The Company reserves the right to specify the type of transformer connection
(e.g. delta-delta, wye-delta, wye-wye) 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 Company System.
To eliminate undesirable interference caused by operation of the Generator Owner’s
Paj 42
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 Company’s system are in the same range as if the generating
equipment were not connected to the Company’s system. The Generator Owner
shall provide an automatic method of initiating a disconnect sequence of his
generating equipment from the Company system with set points noted in the table
below.

taken directly from IEEE (Specific voltage and time

determined for each
installation.)
Note: Trip time refers to the time between when the abnormal voltage condition occurs and
the generator being completely disconnected from the utility Company.
On three phase generator installations, full three phase voltage sensing should be
employed. Voltages must be sensed on the high side of any interface transformer if the
transformer high voltage winding is ungrounded.
The Generator Owner may reconnect to the grid when the system voltage returns to
normal range and is stabilized as defined in Section III, Definitions.
2) Flicker – The Generator Owner shall not cause excessive voltage flicker on the
Company’s system. This flicker shall not exceed the “Borderline of Irritation”
curve, Fig. 10.3, as define in IEEE Std 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 – The operating frequency of the generating equipment shall not
deviate more than the values noted in the table below.

Systems with Inverters Greater than Machine Generating

Note: Trip time refers to the time between when the abnormal frequency condition occurs and
the generator being completely disconnected from the utility Company.
The Generator Owner may reconnect when the system frequency returns to
normal range and is stabilized as defined in Section III, Definitions.
4) Harmonics – Non-linear circuit elements such as inverter can produce harmonics.
Per IEEE std 519, Recommended Practices and Requirements for Harmonic
Control in Electric Power Systems, Table 11.1, 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 Company’s system (Point of Common Coupling).
In addition, the level of harmonic current that the customer is allowed to inject
into the Company’s system shall not exceed that specified in Table 10.3 in IEEE
Std 519. Furthermore, any communication notch should be limited as defined by
Table 10.2 in IEEE Std 519. The preceding requirements apply to all types of
generation systems.
The Generator Owner is responsible for the installation of any necessary controls
or hardware to limit the voltage and current harmonics generated by his
equipment to defined levels.
5) Power Factor – The generator must not adversely impact the power factor of the
Generator Owner site. Most inverters are 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 Generating Systems with Non-Inverter or Rotating
Systems with Inverters Greater than 500kW Machine Generating
Inverters Up Systems
to 500kW
0.95 Lagging 0.95 Lagging or Leading 0.95 Lagging or Leading
or Leading When output exceeds 10%
when output of inverter rating.
exceeds 10%
of inverter
rating.
(From IEEE
929-1999)
However, to the extent that a Generator Owner’s power factor at the Point of
Common Coupling falls below 0.95 lagging as a direct result of the installation of the
generating unit(s), the Generator Owner must obtain, install and maintain, at his
Paj 44
expense, corrective apparatus that compensates for the drop in power factor caused by
the installation of the generator. Penalties will be assessed for power factors that fall
below 0.95 lagging or leading.
6) Current – 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.
Inverter systems should not inject DC current greater than 0.5% of rated inverter
output into the AC interface point under either normal or abnormal conditions.
7) Fault and Line Clearing – The Generator Owner shall automatically disconnect
from the Company’s system during electrical faults on the Company’s electrical
system and upon loss of the Company’s electric source. The Generator Owner
may reconnect when the system voltage and frequency return to normal range and
is stabilized as defined in Section III, Definitions. Detection of the loss of the
Company’s primary electric system, where the Generator Owner is operating in
an island with other customer load, becomes increasingly difficult as the level of
distributed generation on a feeder approaches the connected load. For generating
units 500kW and below, the over/under voltage and over/under frequency settings
described previously along with the anti-islandizing provisions of IEEE 929/UL
1746 inverters, should be sufficient to satisfy this provision.
8) Automatic Reclosing – The Generator Owner is responsible for protecting his
equipment from the effects of switching or automatic reclosing of the Company’s
feeder circuit. The Generator Owner may request the Company to delay high
speed reclosing on the Company’s feeder to allow the interconnected generator
sufficient time to remove itself from an islandized or de-energized feeder prior to
automatic reclose. Since delaying the automatic reclose time degrades the level of
service provided to other customers on the circuit, the Company will limit the
automatic reclose time delays to a few seconds or less. The Generator Owner may
also request that a direct transfer trip scheme be added to remove the
interconnected Generator from service prior to automatic reclosing by using
communications equipment between the generator site and the Company.
Similarly the Generation Owner may request that a synchronizing check, or
reclose blocking scheme be installed on the Company’s feeder to prevent out of
phase reclosing. The Generation Owner is responsible for all costs associated with
the installation and maintenance of these requested modifications.
C. Control, Protection and Safety Equipment Requirements Specific to Generators
of 500 kW or less.
All Generator Owners 500 kW or less can be single phase. Customer owned generators
greater than 10 kW must be evaluated by the Company to determine if it can be single phase.
The following table describes necessary control, protection and safety equipment specific to
generator of 500kW or less connected to Secondary or Primary Voltage Systems:

2. For synchronous and other type of generators with stand-alone capability.
D) Control, Protection and Safety Requirement Specific to Three Phase
Synchronous Generators, Induction Generators, and Inverter Systems.
Generators greater than 500 kW must be three phase machines connected to three phase
circuits.
1) Three Phase Synchronous Generators. Generator circuit breakers shall be three
phase devices with electronic or electromechanical control. The Generation Owner
is solely responsible for properly synchronizing his generator with the Company’s
system. For a synchronous generator, the excitation system response ratio shall not
be less than 0.5 (five-tenths). The generator’s excitation system(s) shall conform, as
closely 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.
2) 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 stated in Section
XIV.B.2. Otherwise, the Generator Owner may be required to install hardware use
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.

2. Selection depends on grounding system, if required by the Company.
3. For synchronous and other types of generators with stand-alone capability.
4. Required only if generator size is greater than Generator Owner’s minimum load and thus capable
of exporting. The relay will operate if the power flow from the generator into the Grid exceeds a
predetermined level. A time delay will have to be incorporated into this relaying scheme to
prevent it from operating during synchronous swings.
5. May be required as part of any necessary transfer tripping/reclose blocking protection scheme.
a. Requirements Specific to Generators paralleling for 0.1 second or less (Closed
Transition Switching)
The table below shows the protective functions required by this requirement for generators
less than 500kW which parallel with the Company’s system for 0.1 second or less such as
during source or load transfers.

2. Scheme will trip generator if closed transition parallel mode remains in effect longer than 0.1
second.
F) Inverter Type – DC Generation installations using inverters for interconnection with the
Company must use non-islanding type inverters as defined in IEEE 519, Recommended
Practices and Requirements for Harmonic Control in Electrical Power Systems, IEEE
929, IEEE Recommended Practices for Utility Interface of Photovoltaic (PV) Systems
(including Annex B, D, E & G) and UL Subject 1741, May 1999, Standard for Static
Inverters and Charge Controllers for use in Photovoltaic Power Systems.
G) Inspection and Start-Up Testing – the Generator Owner shall provide the Company
with reasonable prior notice at least 2 weeks before the initial energizing and start-up
testing of the Generator Owner’s generating equipment and the Company, at its
discretion, shall witness the testing of any equipment and protective systems associated
with the interconnection. The Generator Owner shall revise and re-submit the application
Paj 47
information for any proposed modification that may affect the safe and reliable operation
of the Company’s system. The generator may be reconnected to the Company system
only after the modified application has been reviewed, testing has been confirmed and the
Company has given approval to reconnect.
H) Site Testing and Commissioning - Testing of protection systems shall include
procedures to functionally test all protective elements of the installation up to and
including tripping of the generator and interconnection point. Testing and testing
intervals should be in accordance with manufacturers’ and industry recommendations.
Testing will verify all protective set points and relay/breaker trip timing. The Company
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 Company may review at reasonable times.
I) Metering - Metering requirements will be reviewed on each specific installation.
J) Dedicated Transformer – A dedicated transformer will be required where the
generating Generator Owner is served from the same transformer secondary as another
Company customer and inverter-based technology not meeting IEEE 929-1999 and IEEE
519-1992 specifications is used. In addition, a dedicated transformer or other current-
limiting device is needed for any type of generator installation where the increase in
available short circuit current could adversely impact other Company customers on the
same secondary circuit.
