Oncor Electric Delivery Company is Texas's largest transmission and distribution electric utility, the 6th largest in the USA, serving more than 10 million Texans living in 401 cities and 91 counties in the state. Their service territory includes east, west and north-central Texas, including Dallas, Fort Worth, Midland, Odessa, Killeen, Waco, Wichita Falls, and Tyler and other surrounding cities in Texas.

It was formerly known as TXU Electric Delivery and TU Electric. Predecessor companies include Dallas Power & Light (DP&L), which served the city of Dallas; Texas Electric Service Company (TESCO), which served areas surrounding Fort Worth and west Texas; and Texas Power and Light (TP&L), which served other areas of northern and east-central Texas.

Oncor and Energy Future Holdings[edit]

Oncor is privately held by a limited number of investors including Energy Future Holdings Corporation. Oncor is separate from its owners and separately managed by a majority independent board of directors. While a majority owner, EFH is not involved in the management of Oncor. On March 24, 2016, the Texas Public Utility Commission (PUC) granted the request to convert Oncor into a real estate investment trust (REIT) with the reservation that the PUC would consider the treatment of potential tax savings, which could account to $250M, from the REIT structure in a separate proceeding to be held at a future date. The subsequent proceeding's focus is to determine how the potential tax savings attributable to the REIT format would be shared with utility ratepayers.[1] On 7th July 2017 it was announced that Berkshire Hathaway had agreed a deal to buy the whole of energy future holdings and ultimately Oncor.

Major projects[edit]

Oncor Electric Delivery Company is working in partnership with Siemens Power Technologies to build a smart grid.[2] The company is exploring the use of storage batteries and micro-grids. The Competitive Renewable Energy Zone (CREZ) project improved the transmission of wind power to Oncor's grid.[3]
