13 of top 15 Owner/Operators using PI to Manage Wind Farms Source: Emerging Energy Research

Value Propositions 1.Turbine Manufacturer Warranty Management – “Fox Watching the Hens” – “Bathtub Curve” Implications for LTSA Concept – Need: Focus on Top-Ten Sources 2.Increasing kWh produced – Wind Farm Operations – Turbine Availability – Turbine Operating Efficiency 3.Increasing value of kWh produced – Utility Operations – Improving utility integration (forecasting and scheduling) – Improving market value of power (real-time info to power marketing/trading floor) – VAR/Grid Stability Management 4.“Intangibles” – Corporate Requirements – Enterprise Integration, – Separation of Process Control Network from User/Enterprise – Regulatory & Reporting – Technology Risk Management – Perception and Reality

NPV over 5 Years = 18% Discount Rate Based on US prices, power rate in Spain is.07 to.10/kWh produced For a Single Wind Farm of 150MWs: In a 1 st year ROI of $185,000 NPV over 5 years = 18% Discount Rate

If you overlay the Distribution SCADA load, the difference would be losses or leakage The physical model (CIM) allowing the aggregation and roll-up of individual loads End to end visibility – integrating meter and distribution system(s) operational data
