They said POCO wants a switch installed so they don't get shocked.
In plain English: They're talking about a transfer switch, which can be automatic or manual, and allows the service to receive power from only one source at a time. This prevents the possibility of the generator being connected to the utility supply, which is illegal and extremely dangerous.
Such an interconnection can allow the generator to (attempt to) feed power back into the service conductors. Because transformers work in reverse, too, the high-voltage lines could reach nearly their operating voltage just when the power company repairmen are expecting it to be dead.
This is something you don't want to skimp on with permitting and inspecting, not to mention experience and expertise.
