  15. CLIC 36 kV Double Loop (End Section) Machine Network Service Network

  16. Major Cost Drivers • Power requirements • Connection to 400 kV Grid via new transmission line? • Centrally located main substation (distribution voltages, number of transformers, switchgear, protection, monitoring, etc.) • Remote substations (transformers, switchgear and 400 V panel-boards) • Cables in the tunnel (?) using loop configuration • Transformers (?), panel-boards in tunnel • Emergency generators, cabling, transformers, etc. associated with safety system

  17. What’s Next? • Preliminary design (chronologically) • Loads (voltage, apparent power, power factor, harmonics, locations, etc.) • Network topology (choice of variants, machine and service networks, redundancy, safety networks, underground facilities, etc.) • Main substation preliminary design • Remote substations preliminary design • System simulations • Cost estimate

  18. What’s Next? • June 2010 • Preliminary Design Report • Cost Estimate • Available Resources - discussion
