  1. 1. 1 Infigen Reliability Program James Snelson August 13, 2013
  2. 2. 2 • Infigen Energy ("Infigen") is a leading independent renewable energy business with interests in 24 wind farms (1,646 MW installed capacity) across the United States and Australia. • The name Infigen is derived from the words infinite and generation • infinite, reflecting the unlimited availability of renewable fuel sources • generation, relating to a core function of our business • Founded in June 2003 and listed on the Australian Securities Exchange (ASX) in October 2005. • A leading US renewable energy business • Large operational wind energy business (1,089MW) with 18 operating projects in 9 states • Actively developing utility scale wind and solar projects • Headquartered in Dallas, Texas – 150 US employees • >75% of capacity post warranty – most with in-house operations & maintenance • Australia’s leading specialist renewable energy business • Leading operational wind energy business (556MW) • Diversified, high quality wind energy development pipeline Introduction to Infigen Energy
  3. 3. 3 Engineering Performance Analytics • 1 Meteorologist and 2 Mechanical Engineers • Power Curve / Reliability Evaluations • P50 Resource Assessments • Downtime / Availability / Production Reporting • LiDAR Testing/Evaluations Infigen Technical Services Engineering • 2 Mechanical and 1 Electrical Engineer • Investigate / Design Solutions to Identified Reliability Issues • Work with Wind Farms on Root Cause Analyses • Manage any BETA Testing of New Products and Services being Evaluated for Deployment at the Wind Farms
  4. 4. 4 • Established an internal Gearbox Working Group • Consists of executive management, finance/commercial, field operations, engineering, and engineering performance analytics • Will yield the implementation of purchasing, inspection, and repair specifications • Education of engineering staff: Gearbox Failures and Root Cause Analysis • Joined GRC in Fall 2012 • Added photography equipment to Engineering tool kit • Joined AGMA in December 2012 • Further involvement and participation in both AGMA events and technical committees Infigen Reliability Approach
  5. 5. 5 • Develop Reliability Engineering approach to address and resolve problems, to include: • Failure database • Lubricant data trending and database • Implementation of an RCA program in collaboration with counterparts in Australia • Establishing relationship with metallurgical labs for analysis • Establishing relationships with Universities to provide additional resources • Collaborating with other industries to help resolve common and often similar problems On Going Work
  6. 6. 6 Gearboxes • High Speed and Intermediate Speed Bearing Axial Cracks • Collaborating with other industries to help resolve common and often similar problems Main Bearings • Implementing improvements to current main bearings: auto lubrication, temperature monitoring Yaw Drives • Applying lessons learned from gearbox work into issues with yaw drives Condition Monitoring • Investigating multiple alternatives from a technical and financial perspective On Going Work
  7. 7. 7 Gearbox Problems •Seeing all common issues • Implementation of maintenance practices to identify problems • Investigation of condition monitoring systems (vibration, temperature, oil particle counters) • “Beta Testing” of new and/or innovated technologies Gearbox Problems, Investigation, and Repair
  8. 8. 8 Gearbox Problems, Investigation, and Repair • If a failure occurs we begin an information dump. This involves: • Discussions with site personnel • Retrieving SCADA data • In Situ photographs • Measurements are taken if necessary • Parts are retained or an engineer is present at the gearbox teardown • All efforts made to catch failures early and perform as much work up tower as possible. • Investigating innovated component options and repair procedures
