fpl reads your meter and issues a bill which is due 21 days from the meter reading.
if the bill isn`t paid due date,
your account will become past due.
the system can issue a final notice anytime after a balance becomes past due.
once the notice expires,
your account is eligible for disconnection at anytime.
there are cases where you may go days or weeks without being field selected and other cases where as soon as you become eligible,
your account is field selected.
its a system generated thing though.
it randomly makes selections from all accounts that are eligible for disconnection.
once that happens,
all payment options are suspended and you can either pay the field collector or pay at a pay agent.
