If you're considering solar in North Carolina, you've probably heard about Duke Energy's changing net metering rules. You may have also come across two important schedules: the Net Metering Bridge Rider (NMB) and Residential Solar Choice (RSC).
At first glance, they can seem confusing. Both allow homeowners to install solar and reduce their reliance on the grid. Both provide compensation for excess solar production. Both can generate significant savings over the life of a solar system.
So, which one is better?
The answer depends on your goals, your energy usage habits, and how much control you want over your long-term energy costs.
For most homeowners considering solar before the end of 2026, the Net Metering Bridge Rider offers greater simplicity and predictability. However, Residential Solar Choice can create unique opportunities for homeowners who are willing to actively manage their energy use, particularly when paired with battery storage.
Let's take a closer look at how each schedule works and what the differences could mean for your solar savings.
What Is the Net Metering Bridge Rider (NMB)?
The Net Metering Bridge Rider was created as a transitional schedule between North Carolina's legacy net metering program and Duke Energy's long-term Residential Solar Choice schedule.
Homeowners who install solar and qualify for the Net Metering Bridge Rider before December 31, 2026 can maintain that schedule for up to 15 years from their eligibility date.
For many homeowners, the biggest advantage of NMB is its simplicity.
Under NMB:
- Solar energy offsets your electricity usage throughout the billing cycle
- Net excess production is compensated at Duke Energy's wholesale rate
- There are no time-of-use rates
- There are no critical peak pricing events
- The schedule remains relatively straightforward to understand and predict
While NMB is different from the legacy net metering structure that many early solar adopters enjoyed, it still provides a familiar framework that most homeowners can easily understand.
What Is Residential Solar Choice (RSC)?
Residential Solar Choice is Duke Energy's long-term schedule for residential solar customers.
Unlike NMB, Residential Solar Choice introduces time-of-use pricing, meaning the cost of electricity varies depending on when you use it.
Under RSC:
- Electricity costs change throughout the day
- Peak demand periods carry higher prices
- Critical Peak Pricing events may occur during periods of unusually high grid demand
- Energy management becomes more important
- Battery storage can provide additional financial benefits
For homeowners who are willing to adapt their energy consumption habits or integrate battery storage with their solar panels, Residential Solar Choice can create opportunities to maximize savings. However, it also introduces more variables that can affect your monthly bill.
Net Metering Bridge Rider vs. Residential Solar Choice
The easiest way to understand the differences is to compare the two schedules side by side.
| Feature | Net Metering Bridge Rider (NMB) | Residential Solar Choice (RSC) |
|---|---|---|
| Availability | Available to qualifying customers through Dec. 31, 2026 | Ongoing schedule for new solar customers |
| Billing Structure | Traditional monthly netting | Time-of-use pricing |
| Net Excess Energy Compensation | Wholesale credit | Wholesale credit |
| Time-of-Use Rates | No | Yes |
| Critical Peak Pricing | No | Yes |
| Billing Simplicity | High | Moderate |
| Predictability | High | Moderate |
| Benefits of Battery Storage | Moderate to High | High |
| Energy Management Required | Minimal | Moderate to High |
| Best Fit For | Homeowners seeking certainty and simplicity | Homeowners willing to actively manage or automate energy use |
At first glance, the schedules may appear similar. The most important difference is not how solar panels work under each schedule. It's how electricity is valued and when that value changes.
Why Many Homeowners Are Choosing the Net Metering Bridge Rider
One word came up repeatedly during discussions surrounding Duke Energy's net metering transition: certainty.
The biggest advantage of NMB is not necessarily that it produces the highest possible savings in every scenario.
The biggest advantage is that homeowners know what to expect.
Under NMB:
- Electricity costs remain relatively straightforward
- There are fewer variables affecting savings
- You don't need to track peak pricing periods
- You don't need to shift major household loads to specific times of day
- Future savings projections are easier to model
For homeowners making a significant investment in solar, that predictability can be valuable.
The ability to lock in a known schedule for up to 15 years provides confidence in an environment where utility rates continue to evolve.
Key Takeaway: The biggest advantage of the Net Metering Bridge Rider isn't necessarily higher savings. It's greater certainty about how your solar investment will perform over time.
How Residential Solar Choice Actually Works
Residential Solar Choice uses time-of-use pricing, which means electricity costs more during periods when demand on the grid is highest.
This changes the way homeowners think about energy consumption.
Under NMB, the timing of your energy use matters less.
Under RSC, timing becomes much more important.
Summer Schedule (June Through September)
During summer months, Duke Energy's highest-cost period occurs in the evening.
Summer On-Peak Hours: Weekdays from 6:00 PM to 9:00 PM
Summer Off-Peak Hours: All other hours
This timing creates an interesting challenge for solar homeowners.
Most solar systems produce their highest output between late morning and mid-afternoon. By the time the most expensive hours arrive, solar production is declining or has stopped altogether.
Without battery storage, homeowners may need to purchase electricity from the grid during the most expensive period of the day.
Winter Schedule (October Through May)
In winter, the peak period shifts to the morning.
Winter On-Peak Hours: Weekdays from 6:00 AM to 9:00 AM
Winter Off-Peak Hours: All other hours
These hours coincide with increased demand from heating systems, water heaters, lighting, and morning household activities.
Unlike the summer peak period, solar production is typically minimal during these early morning hours.
As a result, homeowners may rely more heavily on grid electricity during the highest-cost period unless they have battery storage available.
Understanding Critical Peak Pricing
Residential Solar Choice also includes Critical Peak Pricing events.
These events occur when demand on the grid is exceptionally high and Duke Energy needs to encourage customers to reduce consumption.
Examples may include:
- Extreme summer heat waves
- Severe winter cold snaps
- Other periods of unusually high grid demand
Customers receive advance notice before a Critical Peak event occurs, during which electricity costs are substantially higher than normal.
This is one of the reasons batteries and energy management tools become increasingly valuable under RSC.
Reducing consumption during a handful of high-cost events can have a meaningful impact on annual electricity costs.
Where Residential Solar Choice Can Shine
While NMB may be the better fit for many homeowners today, Residential Solar Choice shouldn't be viewed as a disadvantage.
In fact, some homeowners may thrive under RSC.
This is particularly true for those who:
- Own battery storage systems
- Drive electric vehicles
- Use smart thermostats
- Have flexible energy usage habits
- Actively monitor household energy consumption
These homeowners can strategically shift energy use away from higher-cost periods and take advantage of lower-cost times throughout the day.
For households that enjoy optimizing their energy usage, RSC can create opportunities that don't exist under more traditional schedules.
Why Battery Storage Changes the Conversation
Battery storage is one of the most important variables in this entire discussion.
Under both schedules, batteries provide valuable backup power during outages. But, their financial value becomes especially significant under Residential Solar Choice.
| Without a Battery | With a Battery |
|---|---|
| Excess solar production is exported to the grid during the day | Excess solar production is stored on-site |
| Credits are received based on the applicable rate structure |
Stored energy can be used during peak periods |
| Electricity may need to be purchased during higher-cost periods |
Grid purchases can be reduced during higher-cost periods |
| Savings depend more heavily on utility compensation structures | More of your solar production stays under your control |
A battery charged by solar production during the afternoon can later power your home during:
- Summer peak periods (6 PM–9 PM)
- Winter peak periods (6 AM–9 AM)
- Critical Peak Pricing events
This allows homeowners to maximize the value of the energy their solar system already produces.
As net metering rules evolve, batteries are increasingly becoming an energy management tool rather than simply a backup power solution.
Which Schedule Is Best for You?
Every homeowner's situation is different, but there are some general guidelines.
|
Net Metering Bridge Rider (NMB) May Be Best For |
Residential Solar Choice (RSC) May Be Best For: |
|---|---|
| Homeowners who value simplicity | Homeowners adding battery storage |
| Customers seeking predictable long-term savings |
Electric vehicle owners |
| Families with typical usage patterns |
Smart home enthusiasts |
| Homeowners who prefer a straightforward billing structure | Customers willing to shift energy use away from peak periods |
| Customers who want to lock in a known schedule before 2027 | Homeowners who actively monitor and manage energy consumption |
Key Takeaway: The right choice depends on your goals, your lifestyle, and how involved you want to be in managing your home's energy usage.
The Bottom Line
The question isn't whether solar works under the Net Metering Bridge Rider or Residential Solar Choice.
