Universal Citation: NV Admin Code 704.8927

Current through September 16, 2024

1. Except as otherwise provided in NAC 704.8893, electricity generated by a renewable energy system which is authorized to participate in the system of portfolio energy credits must be metered and the renewable energy system shall submit meter readings quarterly to the Commission.

2. Except as otherwise provided in subsections 3 to 13, inclusive, the Administrator shall certify portfolio energy credits to a portfolio energy system or efficiency measure for:

(a) The net output of electricity in kilowatt-hours delivered to the transmission system or the distribution system and sold to a provider of electric service. The net output must be provided to the Administrator by the entity that owns, operates or controls the meters used to monitor the net output of electricity of the renewable energy system.

(b) The amount of electricity used by the portfolio energy system for its basic operations as set forth in NRS 704.78215, if the system:
(1) Is placed into operation on or before December 31, 2015; or

(2) Is placed into operation on or after January 1, 2016, and the provider entered into a contract for the purchase of electricity generated by the portfolio energy system on or before December 31, 2012.

(c) The amount of electricity used by a portfolio energy system that generates electricity from geothermal energy for the extraction and transportation of geothermal brine or used to pump and compress geothermal brine.

Unless otherwise provided for in a contract for renewable energy, the portfolio energy credits certified by the Administrator pursuant to paragraphs (b) and (c) must be awarded to the owner of the renewable energy system.

3. The Administrator shall certify portfolio energy credits for the line loss factor of:

(a) A customer-maintained distributed renewable energy system placed into operation on or before December 31, 2015, by multiplying the metered number of kilowatt-hours generated and used by the customer who is served by the customer-maintained distributed renewable energy system by a factor of 1.05; and

(b) An energy efficiency measure by multiplying the number of kilowatt-hours saved by the energy efficiency measure by a factor of 1.05.

4. For a solar energy system, as defined in NRS 701B.150, placed into operation on or before December 31, 2015, the Administrator shall certify portfolio energy credits for participants in the Solar Energy Systems Incentive Program created in NRS 701B.240 by multiplying the actual kilowatt-hours produced by the solar renewable energy system by a factor of 2.4.

5. For a solar photovoltaic system, as described in NRS 704.7822, placed into operation on or before December 31, 2015, the Administrator shall certify portfolio energy credits by multiplying the actual kilowatt-hours produced by the solar renewable energy system by a factor of 2.4.

6. The Administrator shall certify portfolio energy credits for a system that uses a reverse polymerization process described in NRS 704.7823 by multiplying the actual kilowatt-hours produced by the renewable energy system by a factor of 0.7.

7. The Administrator shall certify portfolio energy credits for electricity saved by a provider during its peak load periods, as defined in the applicable approved tariffs, from energy efficiency measures described in NRS 704.7802, by multiplying each kilowatt-hour of electricity saved by the provider during its peak load period from energy efficiency measures by a factor of 2.0.

8. A solar thermal energy system may use a thermal energy meter to measure the amount of energy generated by the system. The system will be credited with 1 kilowatt-hour of electricity generated for each 3,412 British thermal units of heat generated by the solar thermal energy system.

9. Except as otherwise provided in this subsection, the energy, measured in British thermal units, generated by a geothermal energy system providing heated water to one or more customers must be calculated as (F x T) x 500, less the system losses as calculated by a professional engineer and accepted by the Administrator, where:

(a) "F" equals the flow rate, measured in gallons per minute; and

(b) "T" equals the change in temperature across a heat exchanger or system, measured by the difference in temperature of the incoming fluid in degrees Fahrenheit and the temperature of the outgoing fluid in degrees Fahrenheit after it has passed through the heat exchanger or system.

For heat exchangers used by end-use customers, it is assumed that no system losses occur, and no calculation of system losses by a professional engineer is required.

10. A net metering system will be credited annually with portfolio energy credits based upon the amount of metered electricity generated by the system or, if metering is not used, upon an estimate of the electricity generated by the net metering system by using the method of calculation designated by the Regulatory Operations Staff of the Commission for a solar energy system which does not use a meter to measure the generation of electricity of the system.

11. The portfolio energy credits generated by a net metering system must be assigned to the owner of the net metering system, unless the provisions of paragraph (a) of subsection 3 of NRS 704.775 apply, or another allocation of the portfolio energy credits is provided for in a written agreement between the utility provider and the owner of the net metering system.

12. If the Administrator is required by subsections 4 to 7, inclusive, to apply a multiplier in certifying portfolio energy credits for a portfolio energy system or efficiency measure and he or she determines that more than one multiplier may be applicable to the portfolio energy system or efficiency measure, the Administrator shall only apply the largest applicable multiplier in certifying the portfolio energy credits.

13. The Administrator shall certify portfolio energy credits for electricity saved from energy efficiency measures only for the period during which a provider may use energy efficiency measures to comply with its portfolio standard in accordance with NRS 704.7821 or 704.78213.

14. For the purposes of:

(a) Paragraph (b) of subsection 2, the date on which a portfolio energy system is placed into operation shall be deemed to be the date on which the system is placed into commercial operation and the system's capacity and estimated yearly generation must be measured by the system's capacity and estimated yearly generation on that date.

(b) Subsection 3, the date on which a customer-maintained distributed renewable energy system is placed into operation shall be deemed to be the date on which the system is installed on the premises of the customer and energized and the system's capacity and estimated yearly generation must be measured by the system's capacity and estimated yearly generation on that date.

(c) Subsection 4, the date on which a solar energy system is placed into operation shall be deemed to be the date on which the system is installed on the premises of the participant in the Solar Energy Systems Incentive Program and energized and the system's capacity and estimated yearly generation must be measured by the system's capacity and estimated yearly generation on that date.

(d) Subsection 5, the date on which a solar photovoltaic system is placed into operation shall be deemed to be the date on which the system is installed on the premises of a retail customer and energized and the system's capacity and estimated yearly generation must be measured by the system's capacity and estimated yearly generation on that date.

15. As used in this section:

(a) "Customer-maintained distributed renewable energy system" means a facility or energy system which:
(1) Is used and maintained by an end-use customer;

(2) Uses renewable energy to generate electricity;

(3) Does not use the utility's system to transmit or distribute electricity; and

(4) Uses a meter and other equipment to:
(I) Measure the electricity generated by the energy system; and

(II) Reduce part, but not more than all, of the electrical load of the customer.

(b) "Geothermal energy system" means an energy system that provides geothermally heated water to one or more customers and reduces the consumption of electricity or any fossil fuel.

(c) "Reverse polymerization process" has the meaning ascribed to it in NRS 704.7823.

(d) "Solar thermal energy system" means a renewable energy system that uses solar energy for the purpose of producing heat to reduce directly the consumption of electricity, natural gas or propane.
