FY10 Cost Rate FY11 Rate $1.034 $0.892 CCF $1.800 Where We are Going A Three Step Solution AFFILIATED ENGINEERS, INC. Step One Go Away from Buried Steam Pipe After 2 years the water is gone but … CORROSION FROM THE SALT WATER LEAKS Move to Buried Hot Water With Corrosion Resistant Valves and Fittings AFFILIATED ENGINEERS, INC. Step Two Elevate the Boilers and Chillers Impact of Ike…It could have been far worse ! AFFILIATED ENGINEERS, INC. Step Three Produce On-Site Electricity via Combined Heat & Power (CHP) Combined heat and power systems are approximately 50% more efficient than traditional systems AFFILIATED ENGINEERS, INC. 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 Production On-Site Equipment Power Production Clinical Core Critical Buildings AFFILIATED ENGINEERS, INC. 5.0 MW 15 MW 30 MW X X X X X X Summary of CHP Economic Analysis Note: Variance between all CHP options is within the accuracy of the estimates. AFFILIATED ENGINEERS, INC. CHP Option Five (Recommended) AFFILIATED ENGINEERS, INC. Summary of Pros and Cons Option 1 Option 1A Option 2A Option 3 2 Taurus 60s, 600 psi 2 Taurus 60s, 250 psi 2 Taurus 60s, 250 psi 2 Mercury 50s with combined cycle with combined cycle with HRSG with one Heat Recovery amd one 150 psi steam one 250 psi steam steam turbine all electric chillers turbine driven chiller turbine driven chiller driven chiller Flexible 12,400 tons off grid 12,400 tons off grid Lowest life cycle cost Combined cycle can Lowest life cycle cost be added in the future Electric capacity is Electric capacity is limited by campus heat limited by campus load heat load Higher first cost Cons Complex Operation Requires dematerialized water 600 psi steam system requires higher skilled operators AFFILIATED ENGINEERS, INC. Higher first cost Complex Operation 12,400 tons off grid Electric capacity is limited by campus heat load Recommended Option 5 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 Lowest first cost Flexible Simple operation Simple operation Most Flexible Electric capacity is independent of campus heat load Simple operation 9,600 tons off grid 13,000 tons off grid 13,000 tons off grid Allows the option of an electric heat pump Low life cycle cost Higher first cost Requires stand-by boilers Higher first cost Least flexible More maintenance than turbines Lowest first cost turbine option Pros Option 4A Subject to heating load profile risk More noise and vibration than turbines Will use more ammonia AFFILIATED ENGINEERS, INC.
