Xcel Energy

Using AVEVA™ PI System™ to improve wind forecasting

Xcel Energy has been generating wind power since 2005. But strong winds would often die down unexpectedly, requiring operators to ramp up generation at coal and gas plants at short notice to compensate for the loss in wind power. So, Xcel now uses AVEVA PI System to predict slow wind speeds hours in advance. Now coal and gas plants have plenty of time to turn on and pick up the slack.

“Savings and efficiencies are roughly estimated over the last six years at $46 million.”
