Section 704.775 - Billing; calculation of net energy measurement; treatment of excess electricity; status of net metering system under portfolio standard1. The billing period for net metering must be a monthly period.2. The net energy measurement must be calculated in the following manner: (a) The utility shall measure, in kilowatt-hours, the net electricity produced or consumed during the billing period, in accordance with normal metering practices.(b) If the electricity supplied by the utility exceeds the electricity generated by the customer-generator which is fed back to the utility during the billing period, the customer-generator must be billed for the net electricity supplied by the utility.(c) Except as otherwise provided in NRS 704.7732, if the electricity generated by the customer-generator which is fed back to the utility exceeds the electricity supplied by the utility during the billing period: (1) Neither the utility nor the customer-generator is entitled to compensation for the electricity provided to the other during the billing period.(2) The excess electricity which is fed back to the utility during the billing period is carried forward to the next billing period as an addition to the kilowatt-hours generated by the customer-generator in that billing period. If the customer-generator is billed for electricity pursuant to a time-of-use rate schedule, the excess electricity carried forward must be added to the same time-of-use period as the time-of-use period in which it was generated unless the subsequent billing period lacks a corresponding time-of-use period. In that case, the excess electricity carried forward must be apportioned evenly among the available time-of-use periods.(3) Excess electricity may be carried forward to subsequent billing periods indefinitely, but a customer-generator is not entitled to receive compensation for any excess electricity that remains if: (I) The net metering system ceases to operate or is disconnected from the utility's transmission and distribution facilities;(II) The customer-generator ceases to be a customer of the utility at the premises served by the net metering system; or(III) The customer-generator transfers the net metering system to another person.(4) The value of the excess electricity must not be used to reduce any other fee or charge imposed by the utility.3. If the cost of purchasing and installing a net metering system was paid for: (a) In whole or in part by a utility, the electricity generated by the net metering system shall be deemed to be electricity that the utility generated or acquired from a renewable energy system for the purposes of complying with its portfolio standard pursuant to NRS 704.7801 to 704.7828, inclusive.(b) Entirely by a customer-generator, the Commission shall issue to the customer-generator portfolio energy credits for use within the system of portfolio energy credits adopted by the Commission pursuant to NRS 704.7821 and 704.78213 equal to the electricity generated by the net metering system.4. A bill for electrical service is due at the time established pursuant to the terms of the contract between the utility and the customer-generator.Added to NRS by 1997, 778; A 2001, 3254; 2005, 1816; 2005, 22nd Special Session, 81; 2007, 3005; 2009, 995; 2017, 4284Amended by 2017, Ch. 589,§31.5, eff. 6/15/2017.Added to NRS by 1997, 778; A 2001, 3254; 2005, 1816; 2005, 22nd Special Session, 81; 2007, 3005; 2009, 995
