Title: Performance of Generating Plant


1
Performance of Generating Plant
  • Using Benchmarking for Competitive Advantage
  • Presented by
  • Robert R. Richwine

Agenda
  • Benchmarking Background
  • Unit Level Benchmarking
  • Component Benchmarking
  • High Impact Low Probability Benchmarking
  • Optimum Economic Availability Benchmarking

3
Benchmarking Background
  • From a 2006 Wall Street Journal article
  • Business today is awash in data and data
    crunchers
  • Only a few companies use data as a strategic
    weapon
  • The ability to collect, analyze and act on data
    is the essence of a companys competitive
    advantage

4
Survey Results in WSJ
  • 450 executives 370 companies 35 countries 19
    industries
  • Identified a strong link between extensive and
    sophisticated use of analytics and sustained high
    performance
  • Top performing companies were 5 times more likely
    to single out analytics as critical to their
    competitive edge

5
WEC PGP Case Studies
  • Over 30 case studies published on WEC website
  • www.worldenergy.org
  • Focus is on practical use of data, including
    benchmarking, to improve plant performance

6
Benchmarking - Why?
  • Set realistic, achievable goals
  • Identify opportunities for improvement
  • Give advance warning of threats
  • Determine appropriate incentives
  • Trade knowledge/experience with peers
  • Quantify and manage performance risks
  • Estimate supply adequacy risks
  • Close the gap between actual and potential plant
    performance

7
The Gap
Potential Performance
Actual Performance
8
Worldwide Value of Closing the Gap(WEC Estimate)
  • Economic
  • US80 Billion per Year
  • Environmental
  • 1 Billion Tonnes of CO2e Reduction per Year and
    Proportional Reductions of Other Emissions

9
Primary Causes of the Gap
  • May 2002 Case Study
  • From Analytical Studies Plus Practical
    Experiences
  • Only 20 - 25 of the Gap is Due to Technology
    Issues
  • 75 - 80 is Due to Management Practices

10
Benchmarking plays a key role
  • Many companies have applied benchmarking in
    their performance improvement efforts to
  • 1) Identify gaps in their units performance
  • 2) Identify areas with best opportunity for
    cost-effective improvement initiatives
  • 3) Quantify the economic value of closing those
    gaps

11
Benchmarking Process
  • Identify performance variables to measure and the
    databases required
  • Select peer power plants having similar design or
    mode of operations characteristics
  • Compare the candidate power plants performance
    and cost against these peer plants

12
WEC Data Base
  • Reliability data from around the world
  • Web-based analytical tools

Peer Selection Criteria

Performance Benchmarking Results -- 30 Peer
Units
  • Peer unit selection criteria
  • Subcritical
  • Base-loaded
  • Natural boiler circulation
  • Primary fuel - coal
  • Net output factor greater than 85.6

Conclusions
  • Benchmarking is helping utilities
  • Set goals
  • Develop incentives
  • Identify improvement opportunities
  • Proper peer group selection is essential
  • August 2002 Case Study
  • September 2003 Case Study
  • Benchmarking is a key first step
  • The WEC is actively providing support

22
Component Benchmarking
  • Similar to unit level benchmarking but focused on
    individual
  • Systems
  • Sub-systems
  • Components

23
Component Benchmarking
  • Still need to ensure that the peer selection
    process results in as close a match as possible
    while keeping sufficient units in the population
    for statistical accuracy
  • The component peer selection criteria is likely
    to be different from the unit criteria (e. g. the
    turbine is likely to be indifferent to fuel type)

24
HILP Benchmarking
  • February, 2002 Case Study

25
What is a HILP?
  • High Impact Low Probability Event
  • Happens infrequently but results in extended
    unplanned outages
  • Sometimes called First Time Event
  • (at least the first time it has happened at your
    plant)
  • Includes turbine water induction, boiler
    explosions, generator winding failure, etc.

26
HILP Reduction Program
  • Step 1 Select the best peer group for
    benchmarking against your unit
  • Step 2 Find the peer groups HILP contribution
    to EFOR and compare to your units HILP
    contribution
  • Step 3 Prioritize the peer groups HILP problem
    areas
  • Step 4 Review root cause information
  • Step 5 Assess your plants susceptibility to
    HILPs
  • Step 6 Identify options to avoid, detect and/or
    mitigate HILPS
  • Step 7 Evaluate and select HILP reduction
    options
  • Step 8 Track results of implemented options,
    compare to expectations and feedback into program
    to improve the process

27
HILPs Happen!!
  • No power plant in immune to HILPs
  • While a plants staff must react to the problems
    of the day some resources should be devoted to
    searching for cost-effective ways to prevent,
    detect or mitigate HILPs
  • Benchmarking HILP unreliability, addressing HILP
    causes and seeking solutions before a HILP
    occurs is a proven way to move from a
    fire-fighting to pro-active style of management

BENCHMARKING CONCLUSIONS
  • Benchmarking has been an integral part of many
    successful Performance Improvement Programs
    worldwide (WEC JanApril 2003 May 2004 Case
    Studies)
  • Proper peer selection is vital (WEC August 2002
    September 2003 Case Studies)
  • While traditional performance metrics can show
    important trends, new advanced concepts such as
    Optimum Economic Availability are becoming
    increasingly important in the evolving
    market-driven business environment (WEC July
    2002)
