Net metering is intended to allow customers to generate enough energy for their own use, but not to exceed their own use. Therefore, by state law, excess net metering credits that are more than one year old will expire. Working with your solar installer to make sure your energy consumption is well matched to your solar generation will help prevent losing your credits.
State net metering rules allow some systems to reallocate, or donate, extra net metering credits to a group. If your system application was filed with the state December 31, 2025 or earlier, you may establish a group or add members to an existing group to allocate credits. Net metering groups share extra credits as they’re generated. Adding members to an existing group is as simple as the group designee notifying GMP of new members and allocations by sending an email to [email protected]. Allocation changes will take effect within 30 days and apply to credits generated after that. Changes can be made up to 4 times in a calendar year.
By state law, systems that filed their application with the state on or after January 1, 2025, cannot form a group to reallocate credits.
