Expanded NEM – Net Energy Metering

Expanded NEM is a Net Energy Metering program for residential, commercial, agricultural, or industrial solar, wind or hybrid systems that are 1 megawatt or less and do not qualify for Standard NEM or Wind Energy Co-Metering. Remember that you cannot interconnect your system with the grid until you have been authorized in writing by PG&E.
