What does “behind the meter” solar batteries mean?

“Behind the meter” is defined in the PDRS Rule as End-User Equipment that is installed and supplies energy to a Site with a National Metering Identifier.

This means batteries on the customer side supplying power to a home, business or industrial facility (not front of meter systems, which are connected at the utility side to supply directly to the grid). Only behind the meter battery systems are eligible for incentives under the PDRS.
