LOUISVILLE, Ky. (AP) -- A pair of prisons in western Kentucky are operating on generators after the winter storms knocked out power to the facilities.

Kentucky Department of Corrections spokeswoman Lisa Lamb says the Kentucky State Penitentiary in Eddyville and the Western Kentucky Correctional Complex in Fredonia are expected to be without electricity for another four to five weeks.

Lamb says the 858 inmates at the maximum security penitentiary and 678 inmates at Western Kentucky Correctional are on lockdown as generators and kerosene heaters are being used to keep the inmates warm.

Lamb says extra blankets have been shipped from other prisons to the penitentiary and the department is trying to lease more generators for the prison.
