Coordinated Performance Program & Corporate Culture
What is your #1 Priority in the Power Plant? • Safety • Legal / Environmental Compliance KEEP IT RUNNING! • Capacity # 1 Efficiency
What Determines Efficiency? Efficiency Maintenance Operation Design
What Determines Efficiency? • Design • Cycle • Equipment • Cooling • Emission Controls
AEP Operated Coal-fired Units • First & Largest Operator of Double Reheat Units (worldwide) • 10 Active – 450 to 800 MW • 2 Retired • Largest Coal-fired Units – 6 x 1300 MW • 20 supercritical units • All AEP fossil units built since 1963 were supercritical (does not include units acquired in C&SOE & CSW mergers. Cardinal Plant Gavin Unit 1 – 1300MW
What Determines Efficiency? • Maintenance • Inspection Interval • Level of Refurbishment • Availability for outages
What Determines Efficiency? • Operation • Training • Staffing • Monitoring (availability of Data)
What is Required • Funding ($) • Culture • Will – Dedication – Attitude • Culture is a driving force • Can help offset lack of resources (both $ and staff) • The wrong culture can impair the effectiveness of adequate resources

Infrared Thermography Heat Rate Improvements at Kanawha River Plant Unit 1
Before 2004 GBIR • Managers used the vent stack to determine if the unit was on-line • Average 15,000 #/hr make up to the boiler
Find the Leaks • Steam Cycle places to look • Problem valves • High value valves • Blow down tank • Miscellanous Drain Tank • Condenser Drip Leg • Scans required about 24 hours total (field and reporting). After 2004 GBIR, Average 6,000 #/hr make up to the boiler
Identify Benefits • Make-up Water $ Savings • Fuel $ Savings • Reduced Maintenance $ • Fewer Pulverizers needed for Full Load • Boiler less stressed • Reduced Emissions $ • Culture • Increased Support for the PdM program • Morale Improvements

Formal Testing Program • 1960s • Extensive Program • Faded away by 1970s due to focus on capacity • 1988 • New Test Program Defined in response to Regulatory Interest • Backed by inclusion in the Incentive Compensation Plan • 1990s • Scope Reduced to Mostly Voluntary due to Staffing and Organization Issues Resulting from Restructuring for Competition • 2005 • Revised Voluntary Program to align with Instrumentation and Data Collection Improvements • Future • Full Automation of Collection & Calculation with Station Instrumentation
Formal Testing • Requirements • Corporate Guideline identifies tests and frequency • Instructions for Performing Tests & Calculating Results • In-house developed Performance Test Manual • Type of Instrumentation • Dedicated Test Instrumentation • Installed Plant Instrumentation • PI Data Collection System • Combination of the above
Components of an Integrated Program • Data Evaluation and Test Trends • Automate to the extent possible • Look at trends, do not just accumulate and file • Management and Engineering Reports • Formatting Important • Good Summary • Graphs of trends • Maintenance of Records • Retrievability • Completeness • For Tests, Design Basis, Computer Models, etc.
Heat Rate Deviation Report (HRDR) The Heat Rate Deviation is the difference between the Actual Heat Rate and Baseline Heat Rate. This tool is designed to breakdown the unit deviation into individual equipment and operational components.
HRDR Benefits • Replaces time consuming, manual to semi-automated data collection and calculations requiring a high level of expertise with limited availability of results to others outside of the plant • Engineering or management tool, unlike real time displays that are more of an operations tool • Provides consistent results across the system for easy unit to unit comparison • Widespread data availability
