The Louisiana Public Service Commission(LPSC) was established by the Louisiana Constitution in 1921 in order to ensure that people in Louisiana are provided with utilities at a just and economically efficient rate such that most people can stand to benefit from it.
The five Commissioners who serve in the LPSC are not appointed but are rather elected by the people and they serve a term of six years. This ensures that the independence of the body is maintained for the good of Louisianans.
A president can be impeached for "high crimes and misdemeanors" or an abuse of power. President Trump was recently impeached for breaking a law stated in the constitution about giving aid to foreign countries.
