  3. How to Estimate Reliability ? What is reliability? • Forced outage rate (probability of failures) • System reliability v/s Equipment reliability v/s Component reliability Failure rate Age

  4. How to Measure Reliability and use it for outage scheduling ? • Percent Reserve Evaluation • Capacity exceeding peak load • Loss-of-Load-Probability (LOLP) Method • No. of days / yr of capacity deficiency • Considers probability of simultaneous outages of equipment & daily peak-hr loads • Most popularly used by utilities

  5. A Tool for Operations Monitoring & Improvement: Statistical Quality Control (SQC) • A simple but powerful statistical tool to monitor, diagnose and reduce variation of operating performance of an equipment • Operators and engineers need to be trained in drawing QC charts

  6. SQC helps in Operations Monitoring & Improvement (Mean of X-bar) + (3 Sigma) Mean of X-bar X-bar (Mean of X-bar) – (3 Sigma) Sample points R Sample points

  7. Pre-requisites for Implementing Modern O&M Management tools • Build discipline of data collection • Extensive real time data collection • Updation of static data • Deploy IT for effective data collection, analysis and decision-support • Change mindsets • Greater coordination between functions (e.g. O and M) • Relevant training • New HR systems and Incentive schemes • Move from Standard costing to Activity based costing (ABC)

  8. O&M Challenges When Markets become Competitive & Uncertain • Analytical modeling methods for scheduling will become a necessity to account for • Price volatility (bidding strategies) • Uncertain demands (a function of prices and market rules) • Real-time dispatch • Appropriate technology-mix will become relevant

  9. Enhanced Role of O&M Besides deploying modern management techniques and IT support to increase efficiency (reduce costs) and reliability (service),.. O&M must be seen as playing a strategic role by: • Ensuring lateral consistency with other functions like Materials, HR, Costing/Finance, etc, • Ensuring vertical consistency with Corporate Planning & Strategy • Enabling and helping formulate Business Strategy • Building cumulative capabilities (e.g. methods of reducing outage durations, incremental upgradations, etc) • Sustaining capabilities that cannot be easily copied
