Are you a Sacramento-area homeowner with solar panels? If so, you might be weighing your options amid all the changes in California's net metering rates. With electricity prices from SMUD, PG&E, and other local utilities on the rise, many residents are eager to maximize home energy savings. Adding a home battery is one compelling solution—but there’s a catch: transitioning from the favorable NEM2 rates to the new NEM3 net billing tariffs can impact your bill. Luckily, if you act strategically, you might be able to add battery storage and keep your valuable NEM2 agreement.
How NEM2 Benefits Existing Solar Customers
Homeowners who installed solar panels under California’s Net Energy Metering 2.0 (NEM2) program enjoy substantial benefits. Under NEM2, extra solar power exported to the grid earns high credits—offsetting electricity costs whenever the sun isn’t shining. This made solar a savvy investment from Elk Grove to Roseville and beyond.
But in 2023, California rolled out Net Energy Metering 3.0 (NEM3), sharply reducing export compensation through a new net billing structure. Now, customers considering battery storage wonder: can you keep your NEM2 rates if you add a battery?
Can You Stay on NEM2 After Adding a Battery?
Yes, you generally can—if you follow the proper steps and deadlines.
Submit a Non-Exporting Battery Addition
To preserve your NEM2 status, your battery storage system must be configured as “non-exporting.” This means the energy stored in your battery powers your home but is not sent back to the grid. Utilities like PG&E require signed documentation to confirm your battery won’t export electricity, so it’s critical to work with a solar contractor or battery installer experienced with NEM2 rules. This keeps your entire solar-plus-battery system compliant and eligible for your original NEM2 rates.
Meet Utility Timelines: Act Quickly
Utilities across California, including SMUD, PG&E, and SCE, set strict deadlines for NEM2 add-ons. Most homeowners have a three-year window from their original NEM2 Permission to Operate (PTO) date to gain battery approval while staying on NEM2. If you’re in Folsom, Sacramento, or Roseville and your NEM2 PTO was granted, be sure to check exactly how much time you have left.
Miss the window, and you may be automatically switched to NEM3 rates for your expansion—which may significantly lower your annual home energy savings.
Complete Your Interconnection Application
Before the battery is installed, a supplemental interconnection application must be submitted to your utility. Only after you receive the green light (“PTO” for your battery) can installation move forward. If this paperwork isn’t completed on time and in compliance, you could lose your NEM2 status—and that’s a costly mistake with today’s Sacramento electricity rates.
Why Add a Battery to Your NEM2 Solar System?
Battery storage isn’t just about keeping the lights on during outages. It’s a powerful way to store daytime solar production and use it after sunset, boosting your self-consumption and minimizing grid reliance.
Maximize Home Energy Savings
By storing surplus solar power, you reduce the need to draw expensive electricity from the grid during peak evening hours. This can make a real difference on PG&E or SMUD bills, especially under time-of-use rate schedules.
Enhance Energy Resilience
Sacramento’s summer heat waves or wildfire-related shutoffs can leave entire neighborhoods in the dark. A home battery keeps critical appliances running—offering peace of mind for families throughout Northern California.
Protect Your NEM2 Investment
As long as you follow the non-exporting guidelines, adding a battery lets you enjoy these energy savings and backup benefits without giving up the more generous NEM2 export credits.
Final Tips to Secure Your NEM2 Status
- Always work with a solar and battery installer who’s familiar with NEM2 processes and requirements in your utility area.
- Double-check utility application deadlines and keep documentation for your records.
- Monitor your utility’s policy updates—California’s net metering landscape is still evolving.
Engaging a local expert pays off, whether you’re in Elk Grove, Folsom, or anywhere near Sacramento.
Conclusion: Take the Next Step for Maximum Solar Savings
You’ve invested in solar panels—now maximize your system’s value with battery storage while protecting your NEM2 status. The rules are clear, but timing and paperwork are crucial. Don’t let the transition to NEM3 cut your savings short. Contact a reputable local installer or energy consultant today for a free consultation or a quick tariff comparison. Secure your electricity savings and energy independence for years to come!
