DISCUSSION:
The existing emergency backup generator at the Police Facility is 75 kW and only backs
up a limited number of key Police Department operations. A large number of items are not
currently tied to the existing generator, including some lighting, air conditioning and
computer terminals. The proposed 300 kW generator is sized to allow the Department to
be fully operational during a power outage. There is sufficient excess capacity in the
proposed generator to allow some additional connections to be made, should the
Department require them.
The work necessary for the completion of this contract consists of procuring and
installing a new diesel powered emergency backup generator including removing
