INTERCONNECTION STANDARDS:
Issued by
General Conditions - The following states the general conditions and
requirements and technical specifications for the safe and reliable operation of
interconnected Customer-owned generating facilities, 25 kW or less in capacity,
that are intended to generate energy to serve all or apart of the Customer s load
or for purchase by the Company.
(A) Electrical Generation Systems (25kW and Smaller)
Any electrical generating facility with a maximum electrical generating
capacity of 25 kW or less , including rotating machines (synchronous or
induction generators) with nameplate rating of no more than 25 kVA, must
comply with these standards to be eligible to connect and operate in
parallel with the Company s distribution system.
Application
Each Customer seeking to interconnect qualifying generation will fill out
and submit an application, available on the Company s website or by
contacting the Company. Information must be accurate, complete, and
approved by the Company prior to installing the generating facility.
Customers will be charged an interconnection application fee of $100.
Application Prioritization
All generation interconnection requests for facilities 25 kW or less from
Customers will be prioritized by the Company the same as any new load
requests. Preference will not be given to either request type. The
Company will process the application and provide interconnection in a
time frame consistent with the average of other service connections.

Interconnection Agreement
Prior to interconnection all qualifying Customers will obtain a Certificate of
Completion and sign an appropriate Interconnection Agreement
(documents available on the Company s website or by contacting the
Company). This Agreement between the Company and the Customer
outlines the interconnection standards, billing and revenue agreements,
and on-going maintenance and operation requirements.
Unauthorized Connections
For the purposes of public and working personnel safety, any non-
approved generation interconnections discovered will be immediately
disconnected from the Company s system.
Dedicated Distribution Transformer
To ensure reliable service to all the Company s Customers and
minimize possible problems for other Customers, the Company will review
the need for a dedicated-to-single-customer distribution transformer.
Interconnecting generation under 25kW may require a separate
transformer. If the Company requires a dedicated distribution transformer
the Customer shall pay for all costs of the new transformer and related
facilities.
Metering
(i) Net Metering: The Company shall install, own and maintain a kilowatt-
hour meter, or meters as the installation may determine, capable of
registering the bi-directional flow of electricity at the Point of Common
Coupling at a level of accuracy that meets all applicable standards
regulations and statutes. The meter(s) may measure such parameters
as time of delivery, power factor, voltage and such other parameters
as the Company shall specify. The Customer shall provide space for
metering equipment. It will be the Customer s responsibility to provide
the current transformer enclosure (if required), meter socket(s) and
junction box after the Customer has submitted his/her drawings and
equipment specifications for the Company s approval. The Company
may approve other generating sources for net metering but is not
required to do so.
(ii) Production Metering: The Company may require separate metering for
production. This meter will record all generation produced and may be
billed separately from any net metering or customer usage metering.
The Customer will pay all costs associated with the installation of
production metering.

generating facility, the Customer will obtain the Company s review and
approval. The Company reserves the right to require the Customer, at the
Customer s expense, to provide corrections or additions to existing
electrical devices in the event of modification of government or industry
regulations and standards.
The Company s System Capacity

be limited to 10% of the feeder s peak capacity. However, it is at the
discretion of the Company to allow additional generation interconnection
beyond these stated limits.
Customer-Owned Equipment Protection
It is the responsibility of the Customer to protect their facilities, loads and
equipment and comply with the requirements of all appropriate standards,
codes, statutes and authorities.
Interconnection Costs
Additional costs above and beyond the application fee, if any, will be cost
based and applied as appropriate. For example costs may be incurred for
transformers, production meters, and the Company s testing, qualification
and approval of non-UL 1741 listed equipment.

INTERCONNECTION STANDARDS:
(1)General Conditions The followinq states the qeneral conditions and
requirements and technical specifications for the safe and reliable operation of
interconnected Customer-owned qeneratinq facilities, 25 kW or less in capacity,
that are intended to qenerate enerqy to serve all or apart of the Customer s load
or for urchase b the Com
(A)Electrical Generation Systems (25kW and Smaller)
Any electrical qeneratinq facility with a maximum electrical qeneratinq
capacity of 25 kW or less. includinq rotatinq machines (synchronous or
induction qenerators) with nameplate ratinq of no more than 25 kVA. must
comply with these standards to be eliqible to connect and operate in
parallel with the Company s distribution system.
(B)Application
Each Customer seekinq to interconnect Qualifyinq qeneration will fill out
and submit an application. available on the Company s website or by
contactinq the Company.Information must be accurate, complete. and
approved by the Company prior to installinq the qeneratinq facility.
Customers will be charqed an interconnection application fee of $100.
(C)Application Prioritization
All qeneration interconnection requests for facilities 25 kW or less from
Customers will be prioritized by the Company the same as any new load
requests.Preference will not be qiven to either request type. The
Company will process the application and provide interconnection in a
time frame consistent with the averaqe of other service connections.

(D)Interconnection Aqreement
Prior to interconnection all Qualifyinq Customers will obtain a Certificate of
Completion and siqn appropriate Interconnection Aqreement
(documents available on the Company s website or by contactinQ the
Company). This Aqreement between the Company and the Customer
outlines the interconnection standards, billinq and revenue aqreements,
and on-qoinq maintenance and operation requirements.
(E)Unauthorized Connections
For the purposes of public and workinQ personnel safety. any non-
approved qeneration interconnections discovered will immediately
disconnected from the Company s system.
(F)Dedicated Distribution Transformer
To ensure reliable service to all the Company Customers and to
minimize possible problems for other Customers. the Company will review
the need for ded icated-to-sinq Ie-customer distribution transformer.
Interconnectinq qeneration under 25kW may require a separate
transformer.If the Company requires a dedicated distribution transformer,
the Customer shall pay for all costs of the new transformer and related
facilities.
(G)Meterinq
(i)Net Meterinq: The Company shall install. own and maintain a kilowatt-
hour meter. or meters as the installation may determine. capable of
reqisterinq the bi-directional flow of electricity at the Point of Common
Couplinq at a level of accuracy that meets all applicable standards,
requlations and statutes. The meter(s) may measure such parameters
as time of delivery. power factor. voltaqe and such other parameters
as the Company shall specify.The Customer shall provide space for
metennq equipment.It will be the Customer s responsibility to provide
the current transformer enclosure (if required), meter socket(s) and
junction box after the Customer has submitted his/her drawinqs and
equipment specifications for the Company s approval.The Company
may approve other qeneratinq sources for net meterinq but is not
required to do so.
(ii) Production Meterinq: The Company may require separate meterinq for
production. This meter will record all Qeneration produced and may be
billed separately from any net meterinq or customer usaqe meterinq.
The Customer will pay all costs associated with the installation of
production meterinq.
