PGE Wind Asset Overview – Biglow Canyon
PGE’s first fully owned and operated wind farm
One of the biggest wind farms in the Pacific Northwest and PGE’s largest renewable energy project
Total installed capacity of 450 MW
o 76 Vestas V82 Wind Turbines
o 141 Siemens SWT-2.3-93.
Completed in August 2010
Located on 25,000 acres in Sherman County, OR
o Given the variability of wind power, Biglow produces an average of around 150 MW – enough to power about 125,000 homes

LIDAR Biglow Canyon Wind Farm • T-302 and T321 • 200m Forward-looking LIDAR
measuring wind patterns • Goals: increased generation, decreased
yaw error.

Leveraging Pi Historian
Monitor systems such as:
• Generation output
• Balancing area load
• Component
performance
(pumps, valves, etc.)
24
Reliability Performance Monitoring Center
• RPM Center personnel provide diagnostics and actionable alerts • Increased reliability • Planned outage
• PdP - Advanced pattern recognition for anomaly detection • Condition Based Monitoring for assets based on comparing
current plant operational parameters to historical normal behavior • Earlier warning of sensor issues and equipment degradation than
DCS alarming
