NESolar Savings Explained: How Solar Credits Appear on NES Bills
A complete visual breakdown of how solar energy production, self-consumption, and wholesale export credits are itemized on your monthly Nashville Electric Service bill.
Key Nashville Electric Service (NES) Solar Rules at a Glance
How Your Nashville Electric Service Bill Changes With Solar
One of the most common questions Nashville homeowners ask is: “What does my actual electric bill look like after going solar?”
Understanding the difference between direct self-consumption and grid export credits is key to understanding your true return on investment.
The Two Channels of Your NES Smart Meter
After your solar installation is approved, NES technicians configure your digital AMI meter with two separate registers:
- Delivered (Grid to Home): Measures electricity your home pulls from the Nashville power grid when your appliances need more power than your panels are making (at night, during heavy cloud cover, or when running high-load devices like central heat pumps).
- Received (Home to Grid): Measures surplus clean solar electricity that your home didn’t use at the moment of generation, which flows out to help power neighborhood homes.
Calculating Your Monthly Savings
Here is an example for an 8 kW system in Davidson County producing ~900 kWh in a typical spring month:
- Total Solar Generated: 900 kWh
- Home Direct Consumption (65%): 585 kWh (Saves ~$76 at $0.13/kWh retail rate)
- Surplus Grid Export (35%): 315 kWh (Credits ~$13 at $0.041/kWh export rate)
- Total Monthly Financial Benefit: ~$89 saved in month one
- With Home Battery Storage: Up to 95% self-consumption, boosting monthly savings to ~$115+ by eliminating evening peak grid purchases.
Maximizing Your NES Solar Payback
To get the shortest possible payback timeline on the NES grid:
- Run high-draw appliances during peak daylight: Schedule dishwashers, clothes dryers, and EV chargers to run between 10:00 AM and 3:00 PM when solar production is highest.
- Size appropriately for daytime baseload: Avoid massively oversizing a solar-only system without a battery, because wholesale export credits yield lower returns than direct self-consumption.
- Consider a modular battery: Adding 10 to 13.5 kWh of storage captures daytime excess to power heat pumps, air conditioning, and lights through the night.
How Solar Billing Flows Through Your Meter
How Solar Savings Work in Middle Tennessee (NES / MTE)
How using your own solar power saves money compared to sending power back to the grid
Using solar energy as it's made saves 100% of normal power prices (~13.5¢/kWh). Running appliances during sunny hours saves 3x more than sending electricity back.
Any extra power you don't use is sent to the grid for a smaller credit (~4¢/kWh) applied directly to your monthly electric bill.
Adding a home battery stores extra daytime sunshine, powering your home well past sunset without buying expensive grid power.
Home Battery Backup During Grid Outages
How Solar + Battery Backup Works
Keeps your lights and essential power running automatically during storms and blackouts
Switches from grid to battery power in a split second, so your computers, Wi-Fi, and lights never blink or reboot.
While gas generators quickly run out of fuel, your solar panels recharge your battery system every sunny morning during long power outages.
Clean and whisper-quiet battery mounted neatly on your garage or exterior wall. No engine noise, exhaust fumes, or messy gas cans.
