27.BUY-BACK OF CUSTOMER POWER-Pumping Service:
This offer is available to customers presently taking service under Pumping Service
Schedules 31 or 32 who have historically used at least 50,000 kilowatt-hours of electricity
for the period of May through September and who can provide a minimum of 25 000
cumulative kilowatt-hour savings during the period of May through September in 2001.
Eligible customers will be notified by the Company and must respond to the Company in
writing by April 15 , 2001 if they wish to participate. Participants must acknowledge that
this tariff influenced their decision to reduce their energy consumption. The Company will
pay participants who exceed 50 000 kilowatt-hours of reduced energy usage ten (10)
cents for each kilowatt-hour of reduced energy usage. Participants who do not achieve
000 kilowatt-hours of savings but exceed 25 000 kilowatt-hours will be paid five (5)
cents for each kilowatt-hour of reduced energy usage. Participants who do not achieve
25,000 kilowatt-hours of reduced energy usage will not receive any payment for energy
saved.
The amount of reduced energy usage will be determined by subtracting the
customer s total energy usage for May through September, 2001 from the annual average
of the customer s total energy usage during May through September for the preceding five
years. If the customer does not have five prior years of billing history, the Company will
utilize the billing history available for all prior May through September periods. The
customer must have at least one prior billing history period of May through September
available in order to be eligible. The customer s May through September usage will be
determined based on the customer s first five normal monthly billings occurring on or after
May 15th and ending prior to October 31 st. Verification of energy savings and payment to
customers will occur after October 31 , 2001. This rule expires on October 31, 2001.

27.BUY-BACK OF CUSTOMER POWER-Pumping Service:
This offer is available to customers presently taking service under Pumping Service
Schedules 31 or 32 who have historically used at least 50 000 kilowatt-hours of electricity
for the period of May through September and who can provide a minimum of 25 000
cumulative kilowatt-hour savings during the period of May through September in 2001.
Eligible customers will be notified by the Company and must respond to the Company in
writing by April 15, 2001 if they wish to participate. Participants must acknowledge that
this tariff influenced their decision to reduce their energy consumption. The Company will
pay participants who exceed 50 000 kilowatt-hours of reduced energy usage ten (10)
cents for each kilowatt-hour of reduced energy usage. Participants who do not achieve
000 kilowatt-hours of savings but exceed 25 000 kilowatt-hours will be paid five (5)
cents for each kilowatt-hour of reduced energy usage. Participants who do not achieve
000 kilowatt-hours of reduced energy usage will not receive any payment for energy
saved.
The amount of reduced energy usage will be determined by subtracting the
customer s total energy usage for May through September, 2001 from the annual average
of the customer s total energy usage during May through September for the preceding five
years. If the customer does not have five prior years of billing history, the Company will
utilize the billing history available for all prior May through September periods. The
customer must have at least one prior billing history period of May through September
available in order to be eligible. The customer s May through September usage will be
determined based on the customer s first five normal monthly billings occurring on or after
May 15th and ending prior to October 31 st. Verification of energy savings and payment to
customers will occur after October 31 , 2001. This rule expires on October 31 , 2001.
28.INTERCONNECTION STANDARDS
A. 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 a part of the Customer s load
or for purchase by the Company.(1) Electrical Generation S stems 25 kW 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.
(2) A lication -
Each Customer seeking to interconnect qualifying generation must fill out
and submit an application , available on the Company s website or by
contacting the Company. Information must be accurate, complete, and the
application must be approved by the Company prior to installing the
generating facility. Customers will be charged an interconnection
application fee of $100.
(3) A lication 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 other service connections.(4) Interconnection A reement-
Prior to interconnection all qualifying Customers must 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.(5) 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.(6) Dedicated Distribution Transformer -
To ensure reliable service to all the Company s Customers and to minimize
possible problems for other Customers , the Company will review the need
for a dedicated-to-single-customer distribution transformer. Interconnecting
generation under 25 kW 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.

(7)Meterin
(a) Net Meterin : The Company shall install , own and maintain a
kilowatt-hour meter, or meters, as the Company may deem
necessary, 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 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.
(b) Production Meterin : 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 shall pay all costs
associated with the installation of production metering.(8) Labelin
Common labeling furnished or approved by the Company and
accordance with National Electric Code (NEC) requirements must be posted
on meter bases, disconnects, and transformers informing working personnel
that generation is operating at or is located on the premises.(9) Insurance & Liabilit
Generation facilities permitted under these standards may require additional
insurance and indemnification. Qualifying generation must meet these
interconnection standards and maintain compliance with these standards
during operation.
(10) Future Modification or Ex ansion-
Prior to any future modification or expansion of the customer-owned
generating facility, the Customer must 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.
