The NM Industrial Revenue Bond Act (Section 3-32-1 et seq. NMSA 1978) and County Industrial Revenue Bond Act (Section 4-59-1 et seq. NMSA 1978) provide that any county or municipality may issue IRBs for the purpose of financing electric generating plants, other than one for which both location approval and a certificate of convenience and necessity are required prior to commencing construction or operation of the facility, pursuant to the Public Utility Act [62-13-1 NMSA 1978].
There's also an exemption from the gross receipts tax for certain wind equipment, provided the project is financed with IRBs (Section 7-9-54.3 NMSA 1978).
