SCE Net Metering Guide 2024: Everything You Need to Know

Understanding SCE Net Metering (NEM 2.0)

If you're a Southern California Edison customer in Anaheim, Irvine, Santa Ana, or other SCE service areas considering solar installation, understanding net metering is crucial. Net metering determines how you're credited for the excess solar energy your system produces, directly affecting your savings.

What Is Net Metering?

Net metering is the billing mechanism that credits solar system owners for the electricity they add to the grid. When your solar panels produce more electricity than your home uses, the excess is sent to the grid, and SCE credits your account. Use our solar calculator to estimate your potential credits.

NEM 2.0 vs NEM 3.0: Which Applies to You?

NEM 2.0 (Grandfathered Customers):

Applied to customers who submitted applications before April 14, 2023
Retail rate credits for excess solar production
20-year grandfathering period from interconnection date
Much more favorable economics than NEM 3.0

NEM 3.0 (Current Program):

Applies to applications submitted after April 15, 2023
Export rates approximately 75% lower than NEM 2.0
Time-of-use rates matter more than ever
Battery storage becomes more attractive

How NEM 2.0 Works (For Grandfathered Customers)

If you're fortunate enough to be on NEM 2.0, here's how it works:

1. Real-Time Credit Banking:

Excess solar production during the day creates credits
Credits are used automatically when you consume more than you produce
Credits carry forward month-to-month

2. Annual True-Up:

Once per year, SCE reconciles your account
If you have excess credits, they're typically forfeited (no cash payment)
If you've used more than you produced, you pay the difference
Goal: Size your system to zero out annually without significant excess

3. Time-of-Use (TOU) Rates:

Credits are valued at the rate in effect when energy is exported
Energy consumed is charged at the rate in effect when used
Peak hours (typically 4-9 PM) have highest rates

How NEM 3.0 Works (Current Customers)

NEM 3.0 fundamentally changed the solar economics in California:

Key Differences:

Export compensation reduced by approximately 75%
Export rates vary by time of day (8-9 PM highest value)
Self-consumption is now critical—use what you produce
Oversizing your system provides diminishing returns
Battery storage often makes economic sense

Maximizing Your Savings Under NEM 2.0

If you're on NEM 2.0, you're in an excellent position. Here's how to maximize savings:

Size Your System Correctly: Aim to offset 95-105% of annual usage
Don't Over-Size: Excess annual production is forfeited at true-up
Shift Usage When Possible: Use appliances during peak solar hours
Add an EV: EVs are perfect for using excess daytime solar
Plan for Future Usage: Consider upcoming EVs, pools, hot tubs

Maximizing Your Savings Under NEM 3.0

NEM 3.0 requires different strategies:

Maximize Self-Consumption: Use energy when the sun is shining
Time Your Usage: Run pool pumps, charge EVs, do laundry during solar hours
Right-Size Your System: Larger isn't always better anymore
Consider Battery Storage: Store excess for evening use
Change Habits: Shift usage patterns to align with solar production

SCE Time-of-Use Schedules

SCE offers several TOU rate schedules. The most common for solar customers:

TOU-D-4-9PM:

Peak: 4-9 PM every day
Off-Peak: All other hours
Most common for residential solar customers

TOU-D-5-8PM:

Peak: 5-8 PM every day
Shorter peak window
May be better for some usage patterns

What Happens During Grid Outages?

Important: Standard grid-tied solar systems shut down during power outages for safety reasons. Your solar panels won't power your home during an outage unless you have battery backup with islanding capability.

Net Metering Meter and Monitoring

When you go solar with SCE:

SCE installs a bidirectional (net) meter
Meter tracks energy sent to and received from the grid
You can monitor production through your inverter app
SCE's website shows your net usage and credits

The True-Up Process Explained

Your true-up period begins when your system is interconnected:

Months 1-11: Monthly statements show energy credits/debits, minimal charges
Month 12: Annual true-up reconciles your year
Payment Due: If you consumed more than produced, you pay the difference
Excess Credits: Extra production credits are typically forfeited

Common SCE Net Metering Mistakes to Avoid

Oversizing Your System: Generates credits that are forfeited annually
Wrong Rate Plan: Not all TOU plans are equal for solar
Ignoring Usage Timing: Using energy during peak hours reduces savings
Not Planning for Growth: EVs, pools, and expansions should be considered

Is Battery Storage Worth It?

Under NEM 2.0: Generally not economical unless you need backup power

Under NEM 3.0: Often makes economic sense because:

Store excess daytime solar for evening use
Avoid buying peak-rate electricity
Maximize self-consumption
Provides backup power during outages

Future of Net Metering in California

California's net metering policies continue to evolve. Key trends:

Emphasis on grid-friendly solar adoption
Incentives for battery storage
Time-of-use rates becoming more granular
Focus on self-consumption over export
