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
