The parent company of a power plant near Franklin has announced the layoffs of about 500.
How many are affected at Luminant’s Oak Grove facility was not revealed.
A company spokesman says Oak Grove is a small part of what is described as a reduction in force, which primarily represents support services.
No changes are planned to Oak Grove’s operation.
Most of the layoffs were in north Texas and also affected employees at TXU Energy and TCEH Corporation.
The layoffs targeted overlapping positions at the three companies, which emerged from bankruptcy earlier this month as a single organization.
