Oncor 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 ensures 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
