Oncor is the utility TexPTO lists for Parker County, but other utilities may serve parts of the area — for a specific address, confirm the utility with your meter or a recent bill (the utility is the company that delivers power to this address, which may not be the one that bills you). Residential solar systems typically need both a permit from the permitting authority (where one is required) AND an interconnection agreement from the serving utility before the utility grants Permission to Operate (PTO).
