New Mexico Administrative Code › Title 17 - PUBLIC UTILITIES AND UTILITY SERVICES › Chapter 9 - ELECTRIC SERVICES › Part 570 - GOVERNING COGENERATION AND SMALL POWER PRODUCTION › Section 17.9.570.14 - NET METERING OF CUSTOMER-SITED QUALIFYING FACILITIES WITH A DESIGN CAPACITY UP TO AND INCLUDING 10KW

Current through Register Vol. 35, No. 13, July 16, 2024
A.
				Relationship to other commission rules. The standards and procedures for the
				interconnection of qualifying facilities subject to this section (17.9.570.14
				NMAC) are set forth in 17.9.568 NMAC.
B. Use of a single meter. When the customer
				is billed under a rate structure that does not include time-of-use energy
				pricing, a single energy meter shall be used to implement net metering of a
				qualifying facility unless an alternate metering arrangement is agreed to by
				the customer and utility. If either the utility or the customer requests an
				alternate form of metering or additional metering that is not required to
				accomplish net metering or is for the convenience of the party, the party
				requesting the change in metering shall pay for the alternate or additional
				metering arrangement. If the customer elects to take electric service under any
				rate structure, including time-of-use, that requires the use of metering
				apparatus or a metering arrangement that is more costly than would otherwise be
				necessary absent the requirement for net metering, the customer shall be
				required to pay the additional incremental cost of the required metering
				equipment. Within ten days of receiving notification from the customer of the
				intent to interconnect, the utility will notify the customer of any metering
				costs. Charges for special metering costs shall be paid by the customer, or
				arrangements for payment agreed to between the customer and utility, prior to
				the utility authorizing interconnected operation.
C. Net metering calculation. The utility
				shall calculate each customer's bill for the billing period using net metering
				and with the following conditions:
(1)
				Customers shall be billed for service in accordance with the rate structure and
				monthly charges that the customer would be assigned if the customer had not
				interconnected a qualifying facility. Net energy produced or consumed on a
				monthly basis shall be measured in accordance with standard metering
				practices.
(2) If electricity
				supplied by the utility exceeds electricity generated by the customer during a
				billing period, the customer shall be billed for the net energy supplied by the
				utility under the applicable rates.
(3) If electricity generated by the customer
				exceeds the electricity supplied by the grid during a billing period, the
				utility shall credit the customer on the next bill for the excess
				kilowatt-hours generated, by:
(a) crediting or
				paying the customer for the net energy supplied to the utility at the utility's
				energy rate pursuant to this 17.9.570 NMAC; or
(b) crediting the customer for the net
				kilowatt-hours of energy supplied to the utility. Unused credits shall be
				carried forward from month to month; provided that if a utility opts to credit
				customers and the customer leaves the system, customer's unused credits for
				excess kilowatt-hours generated shall be paid to the customer at the utility's
				energy rate pursuant to this 17.9.570 NMAC.
