Are you really trying to rely on an argument that is totally based off semantics here? TX gave ERCOT the job of running the grid. TX is the entire co-op. No other states but TX are using ERCOT. You can't get TX being anymore involved than they are literally involved.

"The Electric Reliability Council of Texas (ERCOT) manages the flow of electric power to more than 26 million Texas customers -- representing about 90 percent of the state’s electric load. As the independent system operator for the region, ERCOT schedules power on an electric grid that connects more than 46,500 miles of transmission lines and 680+ generation units. It also performs financial settlement for the competitive wholesale bulk-power market and administers retail switching for 8 million premises in competitive choice areas.
ERCOT is a membership-based 501(c)(4) nonprofit corporation, governed by a board of directors and subject to oversight by the Public Utility Commission of Texas and the Texas Legislature. Its members include consumers, cooperatives, generators, power marketers, retail electric providers, investor-owned electric utilities, transmission and distribution providers and municipally owned electric utilities."
ALL of the members are from TX. The funding comes from TX. The employees are Texans. The municipally owned utilities they oversee are built in and power TX. WTF argument are you trying to make??
Governance
The Public Utility Commission of Texas (PUCT) has jurisdiction over activities conducted by the Electric Reliability Council of Texas (ERCOT). ERCOT is governed by a board of directors made up of independent members, consumers and representatives from each of ERCOT's electric market segments.
The Technical Advisory Committee (TAC) makes policy recommendations to the board of directors. The TAC is assisted by five standing subcommittees as well as numerous workgroups and task forces.
The board of directors appoints ERCOT's officers to direct and manage ERCOT's day-to-day operations, accompanied by a team of executives and managers responsible for critical components of ERCOT's operations areas.
