STANDARD METERING AND BILLING AGREEMENT FOR QUALIFYING FACILITIES WITH A DESIGN CAPACITY OF GREATER THAN 10 KW AND LESS THAN OR EQUAL TO 10 MW[1]

 

Graphical Analysis of interconnection rules by Erik Hawkes
 

 

 

  • Large 570 Load Displacement (LD) option is shown above.
    • Utility buys no energy and no RECs. Utility will bill customer at retail rate if he does not produce enough energy to cover his full load.
    • Displaced load is valued at retail rate (that would have been paid to PNM).
    • Customer retains all RECs, but must find buyer on open market. Assume half of  retail rate for RECs. [2]
 

  • Large 570 Net Metering option.
    • Displaced load is valued at retail
    • RECs associated with displaced load are purchased by PNM @ 15 cents/REC
    • Net + associated RECs are purchased at PNM’s avoided cost (for Brown Power); meaning they get those RECs for free.
 

  • Large 570 Simultaneous Buy/Sell option.
    • Utility buys all energy produced and associated RECs at utility’s avoided cost (for Brown power); meaning they get the RECs for free.
    • Customer is billed for all usage at standard retail rate.


[1] 17.9.570.15

[2] Current retail rate is about 4.3 cents/REC. Assume you could sell your RECs for about 2 cents/REC.
