How do I know which policy my system was installed under?

Please contact us to obtain your grid connection agreement. Your grid connection agreement should indicate either the NEM 2.0 agreement or the NBT agreement (2025, 2024, or 2023).

Look for your interconnection application on your records. The utility company likely emailed it as an attachment. The application should show either a NEM 2.0 application or an NBT application.

How are my export compensation rates determined?

Homeowners with solar systems are subject to different export compensation rates depending on their interconnection application date and PTO date.

NEM 2.0 Eligibility: Systems with applications filed before April 15, 2023, and receiving PTO before April 15, 2026, qualify for the NEM 2.0 tariff, which offers fixed rates determined by each utility’s residential rate schedule.
NBT Eligibility: Applications submitted on or after April 15, 2023, fall under California’s Net Billing Tariff (NEM 3.0). Under NBT, export compensation rates are determined by the year in which you receive PTO, referred to as the “vintage year,” and are locked in for 9 years based on the California Avoided Cost Calculator (ACC) for that year.
ACC Vintage Details: Systems with PTO in 2023 and 2024 use the 2022 ACC values for their export rates. Those with PTO in 2025 and 2026 use the updated 2025 ACC values, which reflect changes in energy market conditions, while the overall net billing structure remains unchanged.
