NEM 3.0

What is NEM 3.0 in California and how does it impact me?

NEM 3.0 KEY TAKEAWAYS

    • Solar owners under NEM 3.0 will earn around 75% less for the excess electricity they push onto the grid

 

    • Current solar owners will remain under their existing net metering policy (NEM 2.0)

 

    • Californians can be grandfathered into NEM 2.0 by submitting an Interconnection Application for their solar system by April 13, 2023, maintaining status for 20 years

 

  • Energy storage now benefits your Return On Investment (ROI) by avoiding higher energy rates (enable Peak Shaving

NEM 3.0 Final Decision: The California Public Utilites Commission (CPUC) unanimously voted to approve NEM 3.0. Under NEM 3.0, customers of PG&E, SCE, and SDG&E with solar systems will receive an average of 8 cents per kWh for the excess power they push onto the grid. This is roughly 75% less than the average export rate of 30 cents per kWh under NEM 2.0. IOU customers have until April 13, 2023 to be grandfathered into NEM 2.0 by submitting a complete interconnection application for a new solar system.

Even with the federal solar tax credit back at 30% until 2032, Californians have plenty of reason to go solar sooner than later.

On December 15, 2022, The California Public Utilities Commission (CPUC) passed NEM 3.0, a new net metering policy that will ultimately reduce the monthly energy bill savings for new solar owners.

UNBOUND GRID ASSIST

Empower yourself to Live Unbound

Unbound Grid Assist empowers YOU to make your own decisions on how and when you use your energy while remaining connected to the grid.

Grid assist stores your excess produced energy to be used later at your discretion. This allows you to minimize your utility cost by using your stored energy during peak hours (enable Peak Shaving), power outages, and when the sun is simply not shining.

WHAT CAN UNBOUND DO FOR YOU?

Unbound supports you every step on the way

Unbound designs and delivers a functioning and balanced system to you including  PV system components, a plan set, interconnection application and lifetime support. All with the confidence of the Live Unbound® Promise.

Net Energy Metering (NEM)

What has changed from NEM 2.0 to NEM 3.0?

Prior to NEM 3.0 in California (similar policies are currently under development in several other states), it has become common practice to purchase and install the largest Grid-Tie system a rooftop or the electrical infrastructure of a given household can support. This was due to the additional revenue and Net Metering offset that could be accumulated by exporting excess energy to the grid during the day. 

With the implementation of NEM 3.0, that additional revenue incentive is all but gone. Resulting in larger oversized grid-tie PV systems only extending the Return On Investment (ROI) period for the system, with little to no ability to offset the new higher peak utility rates incurred later in the day and night, when PV is not generating energy.

Rethinking your solar investment return.

Under the new NEM 3.0 rate structures. The best way to optimize your ROI is by installing a PV system sized to offset 100% of your utility bill without excess, utilizing only Ideally-placed Modules not affected by shading, poor orientation, or other identifiable inefficiencies. Unfortunately the average residential household does not have enough Ideal area, let alone general area available to accumulate enough daily export (NEM 3.0 rates) to properly offset the peak rates. 

 

What can be done?

But don’t worry, you can overcome this by adding Energy Storage as part of your Grid-Tie system. These Grid-Tie w/ Storage systems, also commonly called Grid-Assist, store the excess PV energy you generate during the day. This stored energy can then be used by household loads later in the day or evening, reducing reliance on utility power, when utility rates are at their highest. Or even eliminate peak rate charges altogether (known as ‘Peak-Shaving’).

 

Sounds complex? It doesn’t have to be!

Introducing Unbound Grid-Assist system (UGA): a Grid-tie w/ Storage system from Unbound allows you to store energy and have it available to your entire grid-connected household without any major alterations to your existing load panel(s) or electrical system. Using integrated sensors to monitor your households real time load demand and fluctuations, just the right amount of  energy is discharged from the battery(s), through the Grid-Tied inverter(s) single connection point, and to your loads. By providing the exact amount of energy needed without exceeding or lagging, your utility meter effectively stops turning during the desired timeframe. If the loads ever exceed what the inverter(s) and battery(s) can support, the utility seamlessly picks up the slack.

You can even purchase the Grid-Tie system now (latest 3/13/23) and Unbound will provide documentation for you to submit your interconnection application before April 13th, 2023, and add your energy storage later. This will ensure you are ‘grandfathered’ into  NEM 2.0 for next 20 years. Reducing initial system costs to meet your budget, while not affecting your (current) NEM status.
