How can I Sell Solar Energy in Napa County?

Solar owners in Napa County can sell solar energy through net metering (NEM). This involves giving the electrical grid excess energy in exchange for bill credits.

Bill credits help solar panel owners save money on electricity costs. Since the launch of net energy metering, the California Public Utilities Commission (CPUC) has initiated three NEM policies in Napa County:

  • NEM 1.0 (created in 1996)
  • NEM 2.0 (created in 2016)
  • NEM 3.0 (created in 2022)

Customers selling solar energy under NEM 2.0 pay a one-time interconnection fee. Individuals with solar systems under 1 MW will pay between $94 and $145. The interconnection fee for systems over 1 MW costs $800.

Additionally, customers pay non-bypassable fees and take service on TOU rates. Per D.14-03-041, individuals can remain on the NEM 2.0 tariff for 20 years from when they are interconnected or switch to NEM 3.0..

NetMetering 3.0

NEM 3.0 is a new version of the net energy metering policy introduced by the CPUC. All the benefits NEM 1.0 and NEM 2.0 customers enjoy have been grandfathered into this new system for 20 years.

The major difference between NEM 2.0 and NEM 3.0 is the value of export rates. The export rates of NEM 3.0 is 75% lower than that of NEM 2.0. This means that customers will enjoy more extended payback periods and fewer cost savings.

Under NEM 2.0, solar payback periods are between 5 and 6 years but are about 9 to 10 years in NEM 3.0. Also, the NEM 3.0 cost saving is 60% less than NEM 2.0.

NEM 3.0 excludes solar taxes and has an average net export rate of 7.5 cents/kWh. Customers can enjoy reductions in rates if they are eligible for export credit adders. This allows people who apply for NEM 3.0 before the end of 2027 to enjoy higher export credits locked in for nine years. This adder will reduce by 20% annually until the end of the five years.
