A. Upon request of an investor-owned utility in any general rate case, the commission shall approve interconnected customer rate riders to recover the costs of ancillary and standby services pursuant to this section only for new interconnected customers, except that a utility may seek approval of interconnected customer rate riders in the utility's renewable energy procurement plan filing before January 1, 2011, to be in effect until the conclusion of the utility's next general rate case. In establishing interconnected customer rate riders, the commission shall assure that costs to be recovered through the rate riders are not duplicative of costs to be recovered in underlying rates and shall give due consideration to the reasonably determinable embedded and incremental costs of the utility to serve new interconnected customers and the reasonably determinable benefits to the utility system provided by new interconnected customers during each three-year period after which new interconnected customer rate riders go into effect. The benefits to the utility system, as applicable, include avoided renewable energy certificate procurement costs, reduced capital investment costs resulting from the avoidance or deferral of capital expenditures, reduced energy and capacity costs and line loss reductions.

B. In a filing made pursuant to Subsection G of Section 62-8-7 NMSA 1978, a rural electric cooperative may implement rates or rate riders by customer class, giving due consideration to reasonably determinable costs and benefits of interconnected systems, that are specifically designed to recover from interconnected customers the fixed costs of providing electric services to those customers.

C. Nothing in this section shall be interpreted as preventing the utility from charging rates designed to recover all of its reasonable costs of providing service to customers.

D. As used in this section:

1. (1) "ancillary and standby services" means services that are essential to maintain electric system reliability and are required by or are a consequence of interconnecting distributed generation facilities to a utility's system and may include, among other services, regulation and frequency response, regulation and voltage support, spinning reserves and supplemental reserves;
2. (2) "interconnected customer" means a utility customer that is also interconnected to non-utility distributed generation facilities; and
3. (3) "new interconnected customer" means a customer that became an interconnected customer after December 31, 2010 or a customer whose renewable energy certificate purchase agreement entered into prior to January 1, 2011 is no longer in effect.
