Utility Rate

Oncor (TDU): Estimated $0.14/kWh residential rate. McLennan County is in the deregulated ERCOT market. Oncor delivers power as the wires-only Transmission and Distribution Utility (TDU), but you choose your own Retail Electric Provider (REP) which sets your solar buyback rate. Solar export rates vary widely by REP and plan -- shop for a REP with a competitive solar buyback plan to maximize your savings. Illustrative residential rate range: $0.12-$0.16/kWh depending on REP and plan choice.

Why Solar + Battery Storage in McLennan County?

Homeowners in McLennan County are served by Oncor (TDU), which has seen significant residential rate increases in recent years. Residential solar + battery storage offers a way to lock in energy costs at installation prices and protect against future rate hikes.

A solar + battery system combines rooftop panels, battery storage, and inverters to power your home's biggest loads — heating, cooling, and major appliances — while maximizing the power you make and use yourself, plus backup power during grid outages. A licensed local installer sizes and installs the system.

Most of Texas is a deregulated ERCOT market, so solar export (buyback) rates depend on the Retail Electric Provider and plan you choose — they can vary widely. In McLennan County, the reliable value is in storing and using your own power rather than depending on a favorable buyback rate. Ask your local installer about current interconnection and buyback options for your utility.
