N.M. Admin. Code § 17.7.4.13
The utility may submit under seal any portions of its IRP that reveals its contracted portfolio, its major suppliers, transportation volumes, or its contract pricing, on a contract-by-contract basis, to the extent the utility deems specific information to be confidential. The utility also may seek a protective order under Subsection B of 17.1.2.8 NMAC for other portions of its IRP it considers confidential, but the utility shall have the burden of proving its right to such protection. Any information submitted under seal pursuant to this paragraph shall remain under seal for a period of two (2) years, after which time it shall become public unless the utility seeks and obtains further protection from the commission. Information submitted under seal shall be available for review by the commission and its designated representatives and by any person who has entered into a confidentiality agreement with the utility in a form approved by commission order.
