  1. Montana Ambassadors Helena, Montana February 25, 2011

  2. Our Operations • Service territory includes Montana, South Dakota, Nebraska, and Wyoming • 661,000 customers • Electric • 31,700 miles of transmission & distribution • 297 communities • Natural Gas • 8,400 miles of transmission and distribution • 168 communities • Employees – 1,354

  3. Montana Operations • Service territory includes western 2/3 of Montana (107,600 square miles) • Electric • 21,400 miles of distribution • 7,000 miles of transmission • Peak load -1,766 MW Average load – 1,216 MW • Natural Gas • 4,100 miles of distribution • 2,000 miles of transmission • Total delivered – 40 BCF Peak Daily – 335,000 dkt • Employees – 1,037

  4. Our transmission developments… Why Transmission Growth?

  5. Western States RPS Requirements 5

  6. Opportunities - Potential Wind Distribution 6

  7. Montana is between resources & loads

  8. Purpose, Benefit, and Need Our transmission developments… • Meets NWE’s Federal Energy Regulatory Commission (FERC) requirement to respond to new transmission service requests • Provides transmission for new generation development • Enables the development of high quality MT wind power to reach market • Provides and enables positive economic impact to Montana, Idaho and the region • Improves electric system performance and flexibility • Meets the needs of regional electrical demand

  9. NWE proposed transmission projects Collector System Colstrip Upgrade MSTI

  10. Mountain States Transmission Intertie (MSTI) Project 500 kV AC line from Townsend MT to Midpoint Substation near Twin Falls ID Approximately 430 miles depending on final route 1130 miles of alternatives 80+% on State and Federal Public Lands Advanced Stages of Public Siting and Review – began in 2007 1500 MW Path Rating Capacity Expected Current Project cost is $1 billion 10

  11. Montana Renewable Collector System • Currently 4,000 MW in generation interconnection queue • Radial lines to Townsend • Access to MSTI, 500 kV and NWE network • MT-RCS defined by this Open Season • Target in service date is 2016 New Townsend Substation Potential Collector Lines High Wind Area

  12. Colstrip Upgrade • The project is currently being developed primarily by BPA and NWE with the other owners having various levels of interest. • Initially identified in transmission study as being a piece of “low hanging fruit” • No new linear facilities required

  13. Gas Operations

  14. Gas Facts • Four major pipelines cross from Canada into Montana • Carway, Aden, Canadian Montana Pipeline and TransCanada (CMPL is owned by NWE) • Havre – Havre Pipeline and Chinook pipelines tie to Many Islands Pipeline • Morgan/Monchy – Northern Border cross Montana heading to the Mid-West • 485 BCF per year of imports

  15. Gas Facts Carway and Aden come into NorthWestern’s transmission line, and the 15 BCF of imports equals about 38% of our 40 BCF annual market. 15 BCF at the average price of $3.90/mcf in 2010 would be $58.5 million Montana produces about 95 BCF and consumes 76 BCF with most of the difference going into Canada or Northern Border.
