NorthWestern extending deadline to build gas unit

NorthWestern Energy (NYSE:NWE) is getting close to an approval from the Montana Department of Environmental Quality for extended deadline to build a fourth natural gas-fired units at the Dave Gates Generating Station (DGGS) at Mill Creek in Deer Lodge County.

The department is taking public comment until April 2 on a plan to approve requests by NorthWestern Energy for two main things within an existing air permit. On April 7, 2011, NorthWestern Energy contacted the department to notify that the facility’s name had changed from Mill Creek Generating Station (MCGS) to DGGS at Mill Creek.

And on Jan 20, NWE submitted a permit application to request an extension for the construction of Unit #4. The original January 2009 permit allowed NWE phased in construction of up to four simple-cycle, dual fueled generating units each rated at 49.6 MW. The permit had a three-year construction period. Because NWE chose not to construct the fourth unit within three years, NWE is requesting an extension on the construction of the fourth unit. In addition, the permit action updates the current rule references, permit format and the emissions inventory.

The NWE website said the company plans to build DGGS at Mill Creek in two stages. Three 50 MW turbines were scheduled to be completed by the end of 2010. “An additional 50 MW turbine generator will be added later, depending upon the company’s need for additional regulation service,” the website said.
