Net Metering
and Interconnection
PNM is open to allowing its customers to interconnect customer-owned
generation systems to the PNM electric distribution system. There are currently more than 400 customer-owned generation systems of various
sizes interconnected with PNM's distribution system.
Having customer-controlled distributed generation operating
throughout PNM's system is a new consideration in how PNM
operates its distribution system. As a result, PNM has developed
an interconnection procedure and some minimal interconnection
and safety standards to ensure that PNM's distribution system
and the customer-owned generation are compatible and safe
for both the generation owner and PNM employees.
The procedure is easy. In fact, working with PNM up front
can minimize the cost of interconnection.
Interconnection rules and The N.M. Interconnection Manual
Rule 17.9.568 (.pdf) - covers interconnections for qualifying and non-qualifying facilities as large as 10 MW.
The New Mexico Interconnection Manual (.pdf) - to be used in conjuction with Rule 17.9.568 to establish common requirements and a common process for interconnection of generating facilities to a utility.
Rule 17.9.569 (.pdf) - covers interconnections for qualifying and non-qualifying facilities larger than 10 MW.
Rule 17.9.570 (.pdf) - provides guidelines for metering qualifying facilities.
PNM's interconnection process
The interconnection process varies slightly depending on
the type and size of the generating system being installed.
The differences are due in part to the rules and definitions
set forth by the Federal Energy Regulatory Commission rule
that governs cogeneration and small power production.
Summary of definitions
FERC Rule 18 CFR Section 292.203 qualifications (gpoaccess.gov)
Read the following descriptions and select the option that
best describes the facility to be interconnected to the PNM power grid.
