Assembly Bill 1139 Fact Sheet

Dear Solar Partner,

Thank you for looking into our fact sheet about Assembly Bill 1139 which will be put forward on 4.22.21. AB1139 attempts to kill California’s rooftop solar market by:

  • Mandating $50-$90 monthly grid access charges for any and all solar systems regardless of customer type or system configuration.
  • Slashing export credits down to 3 cents per kilowatt hour, a greater than 80% reduction in value.
  • Residential solar would go from a 6 to 8-year payback today to a 20 to 50-year payback under AB 1139.
  • Commercial solar would be equally hard hit.
  • Solar systems paired with energy storage would not escape the negative economics proposed by this bill.
  • The bill makes no exceptions for low-income consumers and would kill the market for schools, farms and many other customer types.
  • The bill would make changes retroactively, impacting the vast majority of NEM 1 and NEM 2 customers.
  • The bill is being sponsored by the California Association of Electrical Workers and the Coalition of Utility Workers. It is being supported by the utilities. It is being authored by Lorena Gonzalez, chair of the assembly appropriations committee, the second most powerful person in the assembly.

Net Energy Metering 3.0 (NEM 3.0) is the incoming law created by the California Public Utilities Commission (CPUC). The new tariffs and fees will impact both residential and commercial solar systems built in California. 

As this notice is posted in November of 2022, the Proposed Decision from the CPUC outlining the proposed NEM 3.0 terms is expected soon. This comes after a year’s delay. Once the new agreement is finalized and passed into law, there will exist a designation of the deadline under which new systems will continue to qualify for NEM 2.0 rates. 

The new NEM 3.0 rates will be designed to lower the value of electricity during the daytime hours, when solar is producing, and increase the value of electricity during the evening hours, when solar homes and businesses purchase electricity. In short, NEM 3.0 will create a “sell low, buy high” proposition to new solar system owners. 

To Californians looking to install a solar system on their home or commercial building, the NEM 2.0 rates will be preferred. As of this post, the solar industry does not know the details of how different the NEM 3.0 rates will be from the NEM 2.0 rates.
