Transmission is a small component of total energy charges. Renewables are emphasized in my comment as they drive down the cost of power (solar is the cheapest form of power currently, batteries firm solar so as it ensure it can be called upon by ERCOT; “dispatchable” is the term of art). Not political.

I don’t live in Texas, but have friends and family that do, so I’ve been there to install renewables and batteries for them and am very familiar with the situation (and also monitor grid stability remotely where their equipment touches the utility); Victoria Electric Cooperative is particularly on my shit list for making public statements that renewables are the cause of ERCOT instability (for political purposes in direct contradiction of the data).
