Understanding California's Net Energy Metering (NEM) Changes & How to Adapt
If you've been following California's solar energy policies, you've likely heard about the major changes to Net Energy Metering (NEM). The transition from NEM 2.0 to NEM 3.0 has sparked many questions among San Luis Obispo County homeowners who rely on solar power to offset their electricity costs. Here’s a breakdown of what’s changed, why it happened, and what you can do next to maximize your energy savings.
What Has Changed with NEM?
Under NEM 2.0, homeowners with solar panels were able to send excess electricity back to the grid and receive near-retail rates as a credit. However, with the shift to NEM 3.0, those compensation rates have dropped significantly—by nearly 75% in many cases. Instead of earning retail value for excess energy, homeowners are now credited at a much lower “avoided cost” rate, which varies based on the time of day and energy demand.
Why the Change?
California regulators argue that the old system disproportionately benefited solar owners while placing financial strain on utility companies and non-solar customers. NEM 3.0 aims to incentivize energy storage and electrification by encouraging homeowners to use or store more of their generated power rather than exporting it to the grid. This shift helps balance electricity supply and demand while supporting grid reliability.
What Can Homeowners Do Now?
With the reduced export rates under NEM 3.0, homeowners need to rethink their approach to solar energy. Here are some key strategies:
1. Install Battery Storage (Tesla Powerwall 3)
Pairing your solar system with a battery like Tesla Powerwall 3 allows you to store excess energy for use when the sun isn’t shining, instead of sending it back to the grid at reduced rates. This means:
Increased self-consumption of your solar energy
Protection against power outages
Lower reliance on grid electricity during peak-rate hours
2. Electrify Your Home
With NEM 3.0 reducing the financial benefits of exporting solar energy, it makes more sense than ever to use your solar power on-site. Electrification upgrades can help, such as:
Electric vehicle (EV) charging: Charge your car using your own solar power.
Heat pump water heaters and HVAC systems: Replace gas appliances with efficient electric alternatives.
Induction cooktops: Reduce dependence on natural gas and maximize solar use.
3. Optimize Energy Consumption with Smart Technology
Smart energy management systems can help you maximize your savings by controlling when and how you use electricity. Features like load shifting, time-of-use optimization, and demand response can make your home more energy-efficient and cost-effective under NEM 3.0.

Final Thoughts
While the shift to NEM 3.0 may feel like a challenge, it also presents an opportunity to rethink energy usage. Californians have invested into solar for a reason, cleaner energy for a better future, and that reason still applies. This is just the next step. Investing in battery storage and electrification can make your home more self-sufficient, resilient, and cost-effective in the long run.
