Section R746-312-15 - Aggregation of Meters for Net Metering Interconnection(1) To measure electricity usage under the net metering program, a public utility must, upon request from an interconnection customer, aggregate for billing purposes a meter to which the net metering facility is physically attached, the designated meter, with one or more meters, the additional meter, in the manner set out in Section R746-312-15. This rule applies only if:(a) the additional meter is located on or adjacent to the premises of the electrical corporation's customer, subject to the electrical corporation's service requirements;(b) the additional meter is used to measure only electricity used for the interconnection customer's requirements;(c) the designated meter and the additional meter are subject to the same rate schedule; and(d) the designated meter and the additional meter are served by the same primary feeder.(2) An interconnection customer must give at least 30 business days' notice to the utility to request that additional meters be included in meter aggregation. The specific meters must be identified when the request is made. If more than one additional meter is identified, the interconnection customer must designate the ranking order for the additional meters to which net metering credits, as defined in Subsection 54-15-104(3) and approved by the governing authority, are to be applied.(3) The aggregation of meters will apply only to charges that use kilowatt-hours as the billing determinant. Other charge applicable to each meter account shall be billed to the interconnection customer.(4) If in a monthly billing period the net metering facility supplies more electricity to the public utility than the energy usage recorded by the interconnection customer's designated meter, the utility will apply credits, as defined in Subsection 54-15-104(3) and approved by the governing authority, to the next monthly bill for the excess kilowatt-hours first to the designated meter, then to additional meters that are on the same rate schedule as the designated meter.(5) If an additional meter changes service to a rate schedule that is different than the designated meter, the additional meter is not eligible for net metering credits, as defined in Subsection 54-15-104(3) and approved by the governing authority, for the rest of the billing year and until the additional meter receives service on the same rate schedule as the designated meter.(6) If the designated meter changes service to a different rate schedule, aggregation of net metering credits is not allowed for the rest of the billing year and may not occur until the additional meters receive service on the same rate schedule as the designated meter.(7) With the governing authority's earlier approval, a public utility may charge the interconnection customer requesting to aggregate meters a reasonable fee to cover the administrative costs of this provision.Utah Admin.
