Gas Compression Implementation: Economic Systems Comparison Josh Malouf Energy Transfer Technologies, L.P.
Energy Transfer Technologies, L.P. Started in 2001 Energy Management by Means of TM Currently 42 Compressor Units in Operation, accounting for 20 Million KWHrs of Monthly Usage ~32 MW of Installed Compression Capacity
This is ESelectTM TM
The Changing Industry Environmental Regulation Cap and Trade?? Tightening Electric Markets Continued Decline in Generating Capacity?? Increasing Horsepower Requirements Decreasing Reserves?? Increasing System Efficiency What metric??
Historical Advantages to Electric Compression Electric Motor Reliability No combustion emissions End User does not have to permit typically Low Capital Cost Substantial increase as compared to a gas engine Motors are much cheaper than engines Low Cost of Maintenance Substantial Savings as compared to a gas engine
Historical Detractors from Electric Compression Starting Current Requires Over-Building the System Fuel Value Electricity Demand Electrical System Reliability Increased and Energy Costs Exposure to Outage No Leasing Market Requires direct capital investment
Four Types of Compression Systems Gas Powered Electric Powered Single Unit, Mutually Exclusive Gas and Electric Powered Units Train Two Unit, Mutually Exclusive Gas and Electric Powered Units
Model Parameters 1500 HP of CDP Gathering HP Two Stage Application, 15 MMscf/d Nominal Throughput Utilized 100% of the Hours Available at 100% Loading Leased Equipment Heat Rate Spread of 2,000 Btu/Hp-Hr for Gas Value and Electric Value Equivalency The Values Presented are for Discussion Purposes only
Capital Cost Electric Package Cost is Lowest However Requires more non-asset cost Train is Highest due to Level of Redundancy Gas Capital Cost is Lowest at TurnKey Level
