Solar Battery for Oncor Customers in Texas
If you’re in Oncor territory and your solar savings changed, storage may be the missing piece.
What Oncor Customers Need to Know
Oncor is the transmission and distribution utility in much of North Texas.
That means:
Oncor delivers electricity to your home
Your retail electric provider sets your energy rate
Delivery charges are applied regardless of provider
Even if your retail plan changes, Oncor delivery charges remain part of your bill.
For solar homeowners, this creates an important reality:
You may still pay delivery charges even if you export energy.
Why Some Oncor Solar Customers See Higher Bills
Common issues include:
Reduced solar buyback rates
Lower export credits than expected
Continued delivery charges
Retail rate volatility
If you’re exporting power at 3–4¢ per kWh but buying back at 14–18¢ per kWh, the spread affects your savings.
Your system may be producing properly.
But the compensation structure changed.
Production and profitability are not the same thing.
How a Solar Battery Helps Oncor Customers
Adding battery storage allows you to:
Store excess daytime solar production
Reduce low-value exports
Use stored energy during high-rate periods
Lower grid imports
Reduce exposure to fluctuating retail rates
Instead of sending excess energy to the grid at reduced credit rates, you keep it.
More self-consumption.
Less dependence on export math.
Greater control over your savings.
Can a Battery Reduce Oncor Delivery Charges?
Delivery charges apply when you draw electricity from the grid.
If battery storage reduces your grid imports, it may reduce:
Kilowatt-hour delivery charges
Exposure to peak usage periods
While you cannot eliminate all delivery charges, reducing grid reliance improves overall bill stability.
The less you import, the less you depend on rate structures you can’t control.
A Battery Upgrade May Be Right If You:
Live in Oncor service territory
Installed solar without storage
Recently saw savings decline
Switched retail electric providers
Export large amounts of daytime energy
Want backup protection during outages
North Texas homeowners often face both rate changes and severe weather.
Battery storage addresses both.
