Solar Battery for TNMP Customers in Texas
If you’re in TNMP territory and your solar savings changed, storage may be the missing piece.
What TNMP Customers Should Know
Texas-New Mexico Power (TNMP) operates as the transmission and distribution utility in parts of:
Coastal Texas
Smaller municipalities
Rural and suburban communities
That means:
TNMP delivers electricity
Retail providers set energy rates
Delivery charges apply to grid imports
Even if you switch providers, TNMP delivery charges remain part of your bill.
Solar production does not eliminate grid delivery structure.
Why Some TNMP Solar Customers See Reduced Savings
Common factors include:
Lower solar buyback rates
Retail rate changes
Continued delivery fees
High seasonal cooling usage
If you export at 3–5¢ per kWh but purchase electricity at much higher retail rates, the gap directly impacts your ROI.
Your panels may still be working properly.
The compensation model shifted.
For homeowners in smaller or coastal TNMP regions, that shift can feel significant.
How Solar Battery Storage Helps TNMP Customers
Adding a battery allows you to:
Store excess daytime solar production
Reduce low-value exports
Use stored energy during high-rate hours
Lower grid imports
Maintain power during outages
Instead of sending excess power back at reduced credit rates, you keep it.
More self-consumption.
Less exposure to fluctuating retail plans.
Greater control over your long-term savings.
Why Backup Power Is Especially Relevant in TNMP Territory
Many TNMP customers live in:
Coastal storm zones
Hurricane-prone areas
Smaller cities with longer restoration timelines
Rural communities
When outages occur:
Standard grid-tied solar shuts off
Homes without storage lose power
A properly configured battery system:
Detects outages automatically
Disconnects from the grid
Powers critical circuits or the entire home
If paired with solar, it can recharge during daylight.
This transforms your solar system from a savings tool into a resilience system.
A Battery Upgrade May Be Right If You:
Live in TNMP service territory
Installed solar without storage
Recently saw buyback credits decline
Export significant daytime energy
Want backup protection
Live in a storm-prone or rural area
If your system is producing but your results changed, storage often restores balance.
Adding a Battery in TNMP Territory
Battery installation typically takes 1–2 days, depending on configuration.
Most modern solar systems in TNMP areas can be retrofitted with storage.
Many homeowners qualify for the 30% Federal Tax Credit on battery installations.

-
TNMP is a delivery utility. Retail electric providers determine buyback plans and credit rates.
-
Delivery charges apply when importing electricity from the grid. Reducing grid imports may reduce variable charges.
-
In many cases, yes. Compatibility depends on inverter and electrical configuration.
-
With proper sizing and configuration, whole-home or large-load backup is possible.
-
Interconnection requirements may apply. Professional installation includes coordination where necessary.
