The emergency generators located in buildings B27-601 (near Guard Gate #1) and B8-601 (near Guard Gate #4) are no longer operating and need to be replaced. Both generators are O'Brien model OB 30K-DW61 generators with 61 horsepower Cummins model 4B-3.9 diesel engines. The generator in building B27-601 has not operated since the 2007 timeframe, and the B8-601 generator was reactivated in 2014; however, it recently stopped working, and repairs are not practical. These generators supply power to the nearby guardhouses (B27-602 and B8-602) during loss of commercial power. The proposed project would replace the generators with two Cummins C30 D6, 30kW, 60HZ, diesel gensets powered by Cummins model 4BT3.3-G5 (50 hp full standby) diesel engines. The new generators would be wired to the distribution system, tie into the stacks and use the current diesel tanks for fuel storage and supply. The proposed action would take place during spring and summer 2016. Approximate Cost is $50,000.
