2 Agenda About UTMB Galveston Hurricane Ike Where We Were September 12, 2008 Where We Are Going A Three Step Solution CHP Options Evaluated New East Plant

3 About UTMB Established in 1891 as the University of Texas Medical Department with one building, 23 students and 13 faculty members is the oldest medical school west of the Mississippi River. 84 acre campus with seven hospitals, more than 70 major buildings, 13,000 employees, 2,500 students and more than 1,000 faculty. Emergency Room at John Sealy Hospital is one of only three Level 1 Trauma Centers in the Greater Houston area.

7 Hurricane Ike, September 13, 2008 Water/Storm Surge Approximately 17 ft to 18 ft based on the information gathered to date. NOAA Timing at High Tide Landfall at approximately 2:10 AM, 2 hours and 4 minutes before the scheduled morning high tide on September 13, 2008 at 4:14am. Image courtesy: noaa.gov

13 Unique Debris Removal Challenges

14 Hurricane Ike, September 12, 2008

15 UTMB Hospital Main Corridor Cleaning of Library Pumping out flood water

16 Back to Work Open 12 Clinics Students back to classes Staff relocations Temporary kitchen, tent cafeteria Temporary sterile processing, pharmacy, and other ancillary facilities

17 Impact of Ike Cost of stabilization: $14,000,000 Unable to operate hospital: 90 Days Lost business revenue: $2,000,000/day Cost of evacuation Steam distribution systems a complete loss Chilled water pits a complete loss Lost research materials Over 1 million sf of campus buildings damaged Estimated 1 billion dollars in damages

18 Where We Were Inability to provide firm supply

19 Impact of Ike (Operating Expense) Natural Gas 7,000,000 6,000,000 5,368,746 5,514,348 6,481,437 6,228,236 $2.000 $1.800 $ ,000,000 4,637,969 $ ,000,000 $1.034 $1.200 CCF 3,000,000 $0.892 $5,701,467 $0.727 $1.000 $0.800 Rate 2,000,000 1,000,000 $4,786,249 $3,370,844 $0.575 $0.588 $3,727,228 $3,663,606 $0.600 $0.400 $ FY07 FY08 FY09 FY10 FY11 $0.000 Use CCF Cost Rate

20 Where We are Going A Three Step Solution

21 Step One Go Away from Buried Steam Pipe CORROSION FROM THE SALT WATER After 2 years the water is gone but LEAKS Move to Buried Hot Water With Corrosion Resistant Valves and Fittings

22 Step Two Elevate or Protect the Boilers and Chillers Impact of Ike It could have been far worse!

23 Step Three Produce On Site Electricity via Combined Heat & Power (CHP) Combined heat and power systems are approximately 50% more efficient than traditional systems

24 Options Given Consideration On October 28, 2010 the Facility Steering Committee directed UTMB Infrastructure Team to proceed with increasing the energy security of the UTMB Campus OPTION 5.0 MW 15 MW 30 MW On Site Power Production Production Equipment Clinical Core X X X X X Critical Buildings X

25 Summary of CHP Economic Analysis Note: Variance between all CHP options is within the accuracy of the estimates.

26 CHP Option Five (Recommended) 5.5 mw Electricity 2 30,000 lb steam/hr 30 psi steam 25,000 lb/hr 75,000 lb/hr Hot Water Convertor 25 MMBtuh Hot Water 75 MMBtuh Hot Water Gas Turbine Heat Recovery Steam Generator Extraction/ Condensing Steam Turbine Generator 30,000 lb/hr 2.5"Hg Surface Condenser 10,810 Btu/kWh Supplemental Fire Gas 250 psi steam (90 95% Efficient) 25,000 lb/hr unfired Fresh Air Firing 75,000 lb/hr fired 75,000 lb/hr fresh air fired

27 Summary of Pros and Cons Recommended Option 1 Option 1A Option 2A Option 3 Option 4A Option 5 2 Taurus 60s, 600 psi combined cycle with one 150 psi steam turbine driven chiller 2 Taurus 60s, 250 psi combined cycle with one 250 psi steam turbine driven chiller 2 Taurus 60s, 250 psi HRSG with one steam turbine driven chiller 2 Mercury 50s with Heat Recovery amd all electric chillers 2 mw gas Engines with Heat Recovery and 4 2mW diesel engines with SCRs and all electric chillers 2 Taurus 60s, with backpressure condensing STG and all electric chillers Pros Flexible Flexible Most Flexible Electric capacity is Lowest first cost Lowest first cost independent of turbine option campus heat load Simple operation Simple operation Simple operation 12,400 tons off grid 12,400 tons off grid 12,400 tons off grid 9,600 tons off grid 13,000 tons off grid 13,000 tons off grid Lowest life cycle cost Lowest life cycle cost Combined cycle can be added in the future Allows the option of an electric heat pump Low life cycle cost Cons Electric capacity is limited by campus heat load Electric capacity is limited by campus heat load Electric capacity is limited by campus heat load Higher first cost Higher first cost Higher first cost Least flexible Complex Operation Complex Operation Subject to heating load profile risk Requires stand by boilers More maintenance than turbines More noise and vibration than turbines Higher first cost Requires dematerialized water 600 psi steam system requires higher skilled operators Will use more ammonia
