Net Billing Tariff

The Net Billing Tariff (NBT), sometimes referred to as Net Metering 3.0 (NEM 3), is the new California solar billing policy that went into effect on April 15, 2023. It applies to all new solar systems sold after April 15, 2023 in the PG&E utility territory.

The Net Billing Tariff (NBT) defines how PG&E customers with solar can earn credits for energy exports. Under NBT, export credits are now valued at the avoided cost to the utility, similar to the wholesale cost of a large power plant. Credits are typically around $0.05 per kWh for most of the year but spike up to $2.87 per kWh when electricity demand is high during September evenings.

Under NBT, homeowners who install a backup battery integrated to their solar power system can achieve greater return on their solar+battery investment by taking advantage of “Time Shifting.”  A battery allows you to store your solar energy and use it later in the day when utility rates are higher, instead of exporting it to the grid for minimal credit, and plan to export during peak electricity demand in September when export credits are 75 times higher.

With a solar + battery system from Cinnamon Energy Systems, you can boost your lifetime savings, and have the added convenience and safety of backup protection during power outages and PG&E public safety shutoffs.
