Who is in charge of the state power grid?
The deregulated power grid in Texas means no one company owns all the power plants, transmission lines and distribution networks, and about 60% of Texas customers choose between dozens of power retailers on an open market.
Electricity generators, such as NRG and Vistra, produce power, while retail electric providers, such as Tara Energy and Griddy, sell it to residents and businesses.
The transmission companies, such as Oncor, transport the power and are compensated by a fee on customerās bills from their electric provider.
A Texas Tribune and ProPublica investigation found that Texas regulators and lawmakers knew about the gridās vulnerabilities for years, but repeatedly prioritized the interests of large electricity providers rather than force expensive changes.
