Workers also prepared Unit 2 for installation of a new steam generator in 2013, a significant investment to support plant operations to 2034, when the unit’s extended operating license expires.
Each Prairie Island reactor is refueled approximately once every 18 months. During refueling outages, Xcel Energy purchases power from the Midwest Independent Transmission System Operator or other utilities or increases electricity production at its other generating plants to ensure an adequate power supply for its customers.
