(A) Customer has elected to operate, at its own expense, a customer-owned, utility-interconnected generation facility. Systems shall be limited in size to not more than five kWh per customer aggregated for a combined total of 53 kWh at the service interconnection point. The generating system is intended to offset either part of or all of the customer’s electrical requirements.
(B) Customer’s generation shall supply alternating current power, 60 Hertz, at a voltage and phase of the town’s established secondary or primary distribution system
(C) If the customer’s generation system full output capacity is larger than 10% of the substation, feeder, or distribution line tap minimum load at the point of interconnection, additional studies and equipment may be required to provide proper line protection and voltage regulation. The customer is responsible for the cost of any studies and or upgrades required to allow safe interconnection of the customer-owned generation.
(D) Standard town retail rates for meter installation may not apply for net metering meters along with possible secondary meters as defined by the town’s fee schedule, except as modified by this chapter or applicable state or federal law.
(E) Any cost or expenses incurred by the town due to modifications made to town’s existing electrical system as a result of the interconnection of customer’s generating system shall be paid by the customer.
(F) Customer will be the owner of the renewable attributes of the electricity that is generated, to include any and all credits, certificates, benefits, environmental attributes, emission reductions, offsets, and allowances, however entitled, attributable to the generation of electricity from the customer-owned renewable generation and its displacement of conventional energy generation. With the above considerations noted the town will not buy back the unused metered electricity but a monthly credit would apply.
(G) Town may require customer to interrupt or reduce deliveries, when necessary, in order to construct, install, maintain, repair, replace, remove, investigate, or inspect any of its equipment or part of its system.
(H) Customer shall comply with all the latest applicable National Electric Code (N.E.C.) requirements (N.E.C. Articles 690 and 705), N.E.S.C. requirements, state requirements, international building codes for roof placements, and shall obtain electrical permits from the town’s Maintenance Superintendent for the equipment installation. Installation shall comply with local requirements.
(I) The meter and transformer or transformer pole serving the customer-generator shall be labeled to indicate potential electric current back feed.
(J) Customer shall provide space for metering equipment and meter base as per town’s requirements.
(K) Customer’s over-current device at the service panel shall be marked to indicate the type of back feed power source.
(L) Customer assumes full responsibility for all maintenance of generators, inverters, and associated equipment including protective equipment. Customer shall keep records of maintenance activities and provide such records to the town for inspection at all times.
(M) Customer’s generation control systems shall comply with N.E.C. Articles 690 and 705 and applicable and current Institute of Electrical and Electronics Engineers (I.E.E.E.) standard including Standard 1547 “Interconnection Distributed Resources with Electric Power Systems” for parallel operation with the town’s electric system. In particular.
(1) Power output control system shall automatically disconnect from the town’s source upon loss of voltage and not reconnect until town’s voltage has been restored for at least five minutes continuously;
(2) Power output control system shall automatically initiate a disconnect from the town’s power source within six cycles (0.1 second) if the customer’s voltage falls below 50% of nominal on any phase;
(3) Power output control system shall automatically initiate a disconnect from the town’s power source within two seconds if the customer’s voltage falls below 88% of nominal or rises above 120% of nominal on any phase.
(N) Customer shall provide a written description of how the protection devices will achieve compliance with the requirements of this chapter as part of the permit application.
(O) (1) Customer shall furnish and install on customer’s side of meter, a UL-approved safety disconnect switch which shall be capable of fully disconnection the customer’s generating facility from the town’s electric system.
(2) The disconnect switch shall be located adjacent to the town’s meter(s) and shall be of the visible break type in a metal enclosure which can be secured in the “off” position with a padlock. The disconnect switch shall be accessible to town personnel at all times.
(P) For systems up to five kWh, the customer shall, at its own expense, maintain in force general liability insurance in the amount of $1,000,000 without any exclusion for liabilities related to the interconnection.
(Q) Additional metering: For purpose of gathering research data, the town may, at its expense, install and operate additional metering and data-gathering devices.
(R) Customer shall pay all cost incurred by the town to have a qualified engineer study, inspect, and approve the customer’s plans and installation.
