That is not correct. Every 10 years by law every community that is served by OGE is offered an election to select who their electrical provider will be. Most times there is no company that wants to compete, so the resolution is passed without vote, just like a city council person that has no person opposing them.It's called a monopoly. They don't give a damn because they know you can't choose another electric company.
I have sympathy with those that lose their electrical power, but a lot of it comes from aging infrastructure that needs to be updated. The only way it can be updated is with short customer outages to replace switches, transformers, etc.
When that is complete, the service reliability should improve.
Nothing can be done when natural disasters take out entire blocks or cities. The electrical grid is an amazing thing if you know how it works with redundancy and the ability to switch around troubled areas that will get electricity back to areas that are suffering losses from natural disasters or auto's hitting poles.
I certainly recommend generators in everyone's home. I live in the country so when an Ice storm hits, we are the last to get service restored. First Priorities are Hospitals, and nursing homes and then businesses that support the community or local government offices, then residential areas. If they can fix an area with 500 homes with one fix, that takes priority over one block of 10 homes.
