  1. Electrical Procurements Thomas C. Nehring, PE Lead Electrical Engineer Conventional Facilities Advisory Committee - Review March 10-11, 2009

  2. Outline Substation Expansion 69 kV to 13.8 kV Substations Expansion Pre-Purchased Equipment Estimated Costs Construction/Procurement Schedule Construction Package Management/Oversight Secondary Unit Substations – for Ring Building Contract Pre-Purchased Equipment Estimated Cost Procurement Schedule Concerns

  3. 69 -13.8 kV Substation Expansion • Scope • Modify 69 kV Yard and Tower @ B 603 • Add 69 kV Breaker • Install 20 MVA Transformer and oil retention pit • Install 15 kV Switchgear and bus duct • Install new ductbank to vicinity of NSLS-2 Site

  4. Overall Electrical Utility Plan Substation expansion and new ductbank

  5. Pre-Purchased Equipment • Pre-Purchased Equipment • 69 kV Breaker • 20 MVA Transformer • 15 kV Switchgear

  6. Estimated Costs • Estimated Costs • $1,975K Construction Contract • $80K 69 kV Breaker • $1,200K 20 MVA Transformer • $445K 15 kV Switchgear

  7. Construction/Procurement Schedule • Construction Package ScheduleBaselineCWE • Bid Package available 3/20/09 3/23/09 • Bid Solicitation 4/14/09 4/13/09 • Bids Returned 5/6/09 4/28/09 • Contract Award 6/17/09 5/29/09 • Notice to Proceed (Construction Start) 6/24/09 6/17/09 • Construction Complete 4/14/11 4/14/11

  8. Construction/Procurement Schedule • Equipment Procurement Schedule • ProcurementEst. Delivery • 69 kV Breaker 4/14/09 2/05/10 • 20 MVA Transformer 5/18/09 7/01/10 • 15 kV Switchgear 5/05/09 2/12/10

  9. Construction Package Management/Oversight • Design • Design by HDR • Design review by NSLS-II • Procurement • Bid solicitation by NSLS-II Procurement & Property Management Group (PPM) • Review by NSLS-II Conventional Facilities (CF) • Construction • Construction management/oversight by NSLS-II CF

  10. Pre-Purchased Equipment for Ring Bldg • Secondary Unit Substations (SUS) • 8 SUS’s that include: • 15 kV Switching • 15 kV Circuit Breaker • 2.5 MVA Transformer • 480 Outdoor Switchgear • 480 Indoor Switchgear

  11. Site Plan Substations

  12. Construction/Procurement Schedule • Equipment Procurement Schedule • ProcurementEst. Delivery • SUS outdoor portion(1,5,RF-1, RF-2) 4/15/09 12/16/09 • SUS outdoor portion(2,3,4,LB) 4/15/09 1/13/10 • SUS indoor portion(1,5,RF-1, RF-2) 4/15/09 2/10/09 • SUS indoor portion(2,3,4,LB) 4/15/09 3/10/10

  13. 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

  14. 69 kV Gas Insulated Circuit Breaker

  15. 20 MVA Main Transformer

  16. 15 kV Switchgear

  17. Main Substation Installation

  18. Secondary Unit Substation
