7. P.M. Grant/W. Hassenzahl DOE Peer Review26 July 1999 Cryoplant Cost vs Power

8. P.M. Grant/W. Hassenzahl DOE Peer Review26 July 1999 Net CryoPower/Cost 30 % !

9. P.M. Grant/W. Hassenzahl DOE Peer Review26 July 1999 Conclusions Tangible energy/cost savings accrue from systems matching and cryo- integration of individual components (e.g., eliminate 300 K terminations) Commercial HTS power components will be emerging from DOE SPI System integration of HTS could play key role in addressing the President’s Critical Infrastructure Directive

10. P.M. Grant/W. Hassenzahl DOE Peer Review26 July 1999 Proposal DOE SPES sponsor design study on integrated HTS power facility (e.g., “Super Substation”) Two SPI teams solicited/selected competiviely as additions to FY00/01 $500 K ea. ($1M total), 1 Year
