Concerns

• Storage of indoor pre-purchased equipment• To be received around the time it can be installed• Indoor Storage Space is available in C-AD complex if needed

• Work in 69 kV yard• Needs to be coordinated around the Lab’s operating schedule• Needs to be coordinated around LIPA’s summer demands• Need to be able to de-energize a portion of the 69 kV bus• Construction scheduled extended to incorporate two summer/fall

periods to allow ample time for shutdowns and coordination with site operating schedules
