Oncor Fixed-Rate Plans

After February's 2021 winter storm decimated Texas's electricity system, many Texans saw extraordinary increases in their electricity bills. For many of them, the cause of this was their variable-rate electricity plan.

Variable-rate electricity plans have rates that change from month to month, with no promises to keep your rate low and no real cap on how high they can go. These plans are also influenced by wholesale prices (what electricity providers pay for electricity). That's why when wholesale prices increased during that winter storm, customers on variable-rate plans felt it too.

To ensure you get a plan that protects you, only features fixed-rate plans. These plans lock in your electricity supply rate for the duration of your electricity plan, which is why they are more likely to save you money than a variable-rate plan. Plus, fixed-rate plans protect you against the unexpected massive electricity bill for as long as you're under contract.

Oncor Power to Choose History

Oncor can trace its roots to TXU Electric. TXU Electric owned three Texas utility companies, including Dallas Power & Light (DP&L), Texas Electric Service Company (TESCO) and Texas Power and Light (TP&L).

In 2007, a number of private equity firms purchased TXU Electric. All three Texas utility companies (DP&L, TESCO and TP&L) now operate together under the name Oncor.

The company that owned Oncor was called Energy Future Holdings. Oncor was its electricity distribution arm, but it also had other businesses in electricity generation. Since TXU utilities were already a part of Texas's deregulated electricity market, Oncor was automatically a part of it as well.

By the end of 2017, Oncor swapped assets with Sharyland utilities. By early 2018, all of Sharyland's retail distribution customers were now to be served by Oncor.

Oncor Delivery (TDU) Charges

Deregulated utilities in Texas have delivery (sometimes called TDU) charges set by the Public Utilities Commission of Texas. These are charges that go directly to Oncor and ensure that Oncor can keep delivering electricity reliably. Since the state sets these charges, they don't change no matter who your electricity provider is.

TDU charges generally change twice a year, on March 1st and September 1st. The charges consist of a monthly base charge and a charge based on your electricity usage (by the kilowatt-hour). You can find these charges by looking at a plan's Electricity Facts Label (EFL). The EFL can be found in the "plan details" section under any Texas plan on
