Catlettsburg Refining
 Complex and energy intensive processes
 Continuous operation 24/7
 Energy is second largest operating cost
 Natural gas – 75%
 Electricity – 25%
 Managing energy is imperative to remaining competitive/viable
 Resources and systems in place to monitor and improve
 Daily operational
 Medium-term activities
 Long-term strategy and projects
 Significant investments made and planned

Catlettsburg Refining
 Expansive electrical infrastructure required
 Refinery footprint is 600+ acres
 There are 130 electric substations and approximately 2,000 electric motors
 120-130 MW of demand to operate refinery
 Largest Kentucky Power customer
 >95% of consumption is for continuously running process equipment
 Significant people resources monitor and maintain electricity infrastructure
 13 engineers
 25 electricians
 60-80 electrical contractor personnel onsite daily
5
Improving Energy Efficiency
 Part of our standard work practices
 Short-term – daily operational monitoring
 Medium-term – maintenance planning activities
 Long-term – strategic projects
 Effective energy management is an “all-above” approach
6
Monitoring Daily Operations
 Significant benefits from daily attention to process operations
 Tuning process heaters
 Optimizing utilization of energy from process operations
 Monitoring sources and uses of steam
 Controlling the operation of large electrical users
7
Monitoring Daily Operations
 Formal assessment program - Focus On Energy initiative – “FOE”
 To accomplish – set standards for performance
 Measure actual performance in real time
 Communicate deviations from standards
8
Monitoring Daily Operations
 Supported by technical, operations, and management personnel
 Completed process unit reviews and identified 148 individual monitoring
points
 Each point assigned a dollar value, tracked and reported
 35% reduction with no investment
9
Medium-Term Activities
 Equipment maintained to perform at optimum efficiency
 Equipment upgrades and major maintenance efforts normally require a unit
shutdown
 Cycle times between shutdowns can be 5-7 years
 Data from routine equipment monitoring is used to develop shut down work
scope
10
Long-Term Strategy/Projects
 On-going efforts to identify and implement energy reduction opportunities
 Energy specific projects – Insulation upgrades, steam leak repairs and
upgrades, on-line analyzers, exchanger bundle upgrades
 Energy assessment for other projects
 Crude unit project example
 Significant investment currently underway
 Process and energy efficiency improvements incorporated into scope
 Redesign of heat integration system to reduce consumption
 Improvements to fired heater for improved efficiency
 Fuel reduction of 720 MMBTU/day
 Electricity reduction of 3,000 kwh/day
11
Long-Term Strategy/Projects
 All projects reviewed for energy efficiency improvement opportunities
 Standard practice to consider high efficiency motors
 Participate in industry benchmarking studies
 Identifies opportunities for improvement
 Share and implement best practices across all MPC sites
12
Summary
 Efficiently using all energy sources is a business imperative
 Resources employed to manage and maintain energy infrastructure
 Programs in place to monitor and improve performance
 Efforts range from daily optimization to large multi-year, multi-million dollar
projects
