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

All rights reserved 28 “Roll-up” Mechanism: Net KWh Roll-Up Load on meter data All AMI meters summed to one distribution transformer All distribution transformers summed to circuit segment Circuit segment summed up to feeder Total feeders summed to sub Key Points Each trend shown is aggregated load (kWh) up to the next higher trend from an individual meter, transformer, line segment, breaker and sub. 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
