Net Excess Generation Notes
  • A dual register meter will record both the kWh purchased and the kWh generated onto our system. Both registers are read at the beginning of the month and the kWh purchased are calculated at your current rate while the kWh generated onto our system are calculated at our avoided cost.
  • If the dollar amount of credit is greater than the dollar amount of your energy charge, the difference will be put into your “cogen bank” to be applied in future months as needed. The bank resets on April 30th of each year. Any remaining balance will be cleared on this date.

SLD Reqs
  • A lockable disconnect is to be provided in close proximity (within 10') of the revenue meter so we can disconnect the inverter, if necessary. The disconnect will need to be visible from the meter
  • Must include size in AC and DC, disconnect location from the meter (in ft), and location of signage.
  • Singular Point of Interconnection: All generation sources must be able to be shut off by a singular lockable, knife-handled disconnect.
Install Reqs
  • The disconnect is required to have a visible open point.
  • Breaker type disconnects are not allowed.
  • Disconnects are not allowed to be attached to SWECI transformer poles or meter poles.
  • The inverter is not to be interconnected to the utility until it has passed commissioning and a dual register meter has been installed.
Placards
  • Label the disconnect as an interconnected generation source.
  • If panels are on a different building than the utility meter, the label must also show the disconnect’s location.

Compiled from public records, 2026. Tariffs and interconnection rules change; verify with Southwestern Electric Coop 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.
