System Offset Notes

You cannot generate more than 120% of a year’s usage. It also depends if a certain feeder is oversaturated with PV, then we look at each system individually to determine if there will back feed on our transmission system.

Plans & docs

SLD Reqs

Relay Meter Orientation = Over/Under


REC METER REQUIRED: The wiring from the solar side should be on the top lugs of the meter. The bottom lugs should go to the utility side. 

Electric Service Reqs

Must meet NMPRC Ruling 568 and NMPRC Ruling 570

Install Reqs

We would encourage all interconnections to include the installation of a meter base for a Renewable Energy Certificate (REC) meter. In addition to the benefits of the utility meter registering the net of forward and reverse consumption, the REC meter, installed on the output (AC side) of the inverter, would register everything your unit would generate. Every 1,000 kilowatt-hours generated would create one REC, which for systems 25 kW and smaller, OCEC would then purchase at a defined rate of $1.00 per REC.

Compiled from public records, 2026. Tariffs and interconnection rules change; verify with Otero County Electric Cooperative before you rely on this. The useful move: if an installer says you need a main panel upgrade, ask how these tap and interconnection policies were considered first.
