| theflyonthewall.com: | NorthWestern Energy announces outage of generating station | | NorthWestern Corp., d/b/a NorthWestern Energy, announced that its Dave Gates Generating Station will be down for a period of up to several months following the discovery of a problem within the gas turbines on each of the three generation units. One of the 50-megawatt units was taken off-line in mid-January due to a vibration alarm. One of the turbines has been removed and sent back to the manufacturer, Pratt & Whitney, for repair. Inspections of the other two units, each of which is fitted with two gas turbines, indicated similar concerns. Although functional at the time, NorthWestern took the remaining units out of service this week to prevent further damage. The turbines, which are under warranty, will be removed and repaired. The plant had a full year of successfully keeping the Montana electric network in balance and operating reliably, as loads on the system and resources available to meet those loads continually move up and down. NorthWestern plans to resume production on each unit as the turbines are inspected, reinstalled, and tested with the first unit back in production perhaps within 45 days. The plant is anticipated to resume full production within 90 – 180 days, barring any unforeseen circumstances. :theflyonthewall.com |
