>ERCOT is a membership-based 501(c)(4) nonprofit corporation,[11][12] and its members include consumers, electric cooperatives, generators, power marketers, retail electric providers, investor-owned electric utilities (transmission and distribution providers), and municipally owned electric utilities.[13]
You are uninformed. ERCOT is heavily influenced (“owned”) by Investor Owned Utilities (IOUs) and market makers that are profit seeking entities. This is true of all ISOs for all intents and purposes. It is the primary reason why the U.S. grid is slow to innovate/change, e.g., implementing distributed generation participation in wholesale markets, etc.
And who are those? Wikipedia says:

It's not "owned" by anyone.
