RIDER NB-C: Commercial Net Billing Rider for Small Renewable Generation Systems


This Rider is available in conjunction with any of the Cooperative’s Commercial Service schedules where a consumer-owned small renewable generator (wind, photovoltaic, biomass-fueled, hydro) is designed to offset a portion or all of the consumer’s electrical requirements normally supplied by the Cooperative, has been installed on the consumer-side of the meter, is interconnected with and operated in parallel with the Cooperative’s electric distribution system, and the consumer’s intent is to purchase all power requirements from the Cooperative net of any power generated by the consumer’s renewable energy system in any given hour. Any power produced in excess of the consumer’s electrical requirements shall be delivered to the Cooperative.

Service on this Rider shall only be available to consumers who own the property where electrical service is received from and delivered to the Cooperative. The nameplate rating of the small renewable generator must be the lesser of (1) the consumer’s estimated maximum 15-minute integrated demand, (2) the consumer’s Contract Demand, or (3) 500 kW. Small renewable generators connected in parallel with the Cooperative’s facilities must have safety, system protection, and power quality equipment installed and operated in accordance with the rules of the Cooperative. Consumers receiving service under this Rider agree to assign the Renewable Energy Certificates (RECs) and all environmental attributes associated with the small renewable generator to the Cooperative

Service under this Rider shall be available in all territory served by the Cooperative only under written contract and shall be subject to the Cooperative’s established Service Rules and Regulations as filed with the North Carolina Utilities Commission. The provisions of the Schedule with which this Rider is used are modified only as shown herein.

Type of Service

Service under this schedule shall be single-phase at a voltage of 120/240 or three-phase at a voltage of either 120/208 or 240/480, 60 cycles. The type of service supplied will depend upon the voltage available. Prospective consumers should ascertain the available voltage by inquiring at the nearest Cooperative office before purchasing equipment. Three-phase voltage, other than the foregoing, is subject to mutual agreement between the Cooperative and the consumer. Other types of installations may be permitted, subject to approval by the Cooperative.


The following charges and credits will be added to the consumer’s monthly bill:

Supplemental Monthly Basic Facilities Charge: $37.60
Credit for energy delivered to the Cooperative: 2.82 ¢per kWh

The monthly minimum bill for consumers receiving this service shall be no less than the Basic Facilities Charge in the rate schedule with which this rate is used, plus the supplemental Basic Facilities Charge as stated in this schedule, less any credits for energy delivered to the Cooperative’s system.

Metering Requirements

The Cooperative will furnish, install, own, and maintain metering to measure energy (kilowatt-hours) delivered by the Cooperative to the consumer and the energy delivered from the consumer to the Cooperative. When a consumer requests that the Cooperative supply electric service in a manner that requires equipment and facilities beyond those that the cooperative would normally provide, and the Cooperative finds it practical to do so, such excess equipment and facilities will be provided as additional facilities at a cost to the consumer. Costs will be collected through additional facilities charges and/or contributions in aid-to-construction as agreed upon by the Cooperative and the consumer-owner. Due to the complexity and cost of some metering installations, the consumer should contact the Cooperative regarding different metering options prior to the purchase of equipment.

Interconnection Requirements:

The consumer must submit an application to interconnect the small generation system which must be approved by the Cooperative. Upon approval of the application, and prior to interconnection to the Cooperative’s electrical system, the consumer must sign an interconnection agreement certifying:

  1. All renewable energy systems equipped with a voltage inverter shall be manufactured, installed, and operated in compliance with Underwriters Laboratory (UL) standard 1741 for distributed generation and have been identified and listed as “utility-interactive”.

(Note: Induction type generators shall be approved on a case-by-case basis.)

  1. That the system installation complies with the National Electric Code (NEC) and all applicable codes and that the system has been inspected and approved by the electrical inspector having legal
  2. The system shall be installed, operated, and maintained in accordance with the manufacturer’s, government, and industry standards and
  3. The system shall be installed, operated, and maintained in accordance with the Cooperative’s Bylaws Service Rules and Regulations, and the Small Generation Interconnection Agreement at all times.

Contract Term

The contract period for service under this Rider shall be one (1) year and thereafter shall be automatically renewed or successive one-year periods, subject to the availability and terms of the rate of the Small Generation Interconnection Agreement. Service may be terminated by the consumer-owner or the Cooperative in accordance with the terms as stated in the interconnection agreement. The Cooperative reserves the right to inspect the consumer’s small generation system at any reasonable time and to immediately disconnect the consumer’s system without providing prior notice should it be necessary to address a hazardous condition or for failure to comply with any of the specifications and requirements as stated in the Small Generation Interconnection Agreement.
