  2. Agenda • Overview of PPM Energy • Business Drivers and Objectives at PPM • Basic Technology Overview • Business Value Achieved • Questions

  3. Who is PPM Energy? • Competitive power and gas storage subsidiary of ScottishPower. • Almost 450 employees in US and Canada, headquartered in Portland, Oregon with offices in Houston, Texas and Calgary, Alberta. • The #2 provider of wind energy in the U.S. with control of ~1,900 MW of wind power. • Recently Acquired By Iberdrola making us the largest provider of Wind in the World. • More than 8,000 MW of wind in our development pipeline. • Goal of more than 3,500 operating megawatts by 2010.

  5. Challenges Associated With Wind • Intermittent Nature of Wind as a Fuel • Wind is considered “energy” not “capacity” • Number of Units required to Monitor and Maintain • Many assets widely geographically distributed • Non Standardization of Assets • Assets and technologies from various vendors • Remote locations • Wind rich areas are usually remote • Complexity of Power Markets • Wind can be “Merchant” • Certain RPS and PTC legislation impact markets

  6. PPM Energy Business Drivers • Improved Forecasting • Ability to more accurately forecast wind improves market performance • Ability to monitor key performance indicators • Massive amounts of data distilled into impactful KPI for rapid understanding of asset performance • Ability to quickly respond • Real time assessments improve market performance • Ability to quickly identify Bad Data • Reducing business decision risks associated with poor information

  7. What’s In Play at PPM • PI Server Components: • PI Server • PI ACE – • PI Client Applications: • PI Process Book • PI Datalink • PI Interfaces: • Modbus • OPC • Loggernet • PI to PI

  12. Availability Tracking Draft based on fabricated Data

  13. PPM Focus on Forecasting • Daily and Hourly feed of Turbine level and Met Tower Data from Pi Historian to Forecasting Service. • Daily 24 Hour Shaped Forecast Produced Based on Climatology and park information • Rolling 6 Hour Forecast Based Mostly on Current • Increase Accuracy can have a significant value in reducing exposure to the Market Imbalance

  14. PPM Focus on Performance Monitoring • Fuel Amount • Capacity Factor • Conversion of Fuel • Availability/Power Curve • Market exposure • Contract • Market Execution • Daily Buying and Selling/forecasting

  15. PPM Business Value Achieved • Conversion of Reliability to Lost Energy • Supports O&M contractual obligations • Quantifies operational Data • Valuation of Lost Output Converted based on Contract Terms • Supports prioritization • Isolation of Market Exposure • Provides an ability to minimize risk of price uncertainty and volatility

  16. PPM Business Value Achieved • Improvement in key indicators • Better Understanding of Market • Better Data For Historical Analysis • Ability to Value performance in terms of MHh and Dollars • Quicker response times to critical issues
