A MESSAGE FROM OUR PRESIDENT AND CEONorthWestern Energy’s mission is to deliver safe, reliable and innovative energy service for our 726,400 customers across Montana, South Dakota, Nebraska and Yellowstone National Park in Wyoming. We are proud to be a valued member of the 318 communities in Montana and South Dakota we supply with electrical service, along with Yellowstone National Park in Wyoming, as well as the 180 communities in Montana, South Dakota and Nebraska we supply with gas service.

These cities and towns are much more than places on a map. They are home to our 1,500 employees, who are active in their communities. They volunteer, they serve and they lead. NorthWestern Energy encourages employees to give back, and as a company we do the same. We are a responsible and active corporate citizen.

About 80 percent of our employees regularly volunteer, a remarkable statistic. NorthWestern Energy supports our employees’ dedication by investing more than $1.7 million in 2018 in charitable donations and sponsorships, economic development opportunities, United Way, chambers of commerce, scholarships and professional association dues. When our employees volunteer, NorthWestern provides a grant to the non-profit organizations they serve. I have the privilege of sending out letters to our employee volunteers, thanking them for their service and notifying them of grants for their favorite organizations. It is something I look forward to because it conveys the range of our employees’ commitments to serving our communities.

Community Works is our report to you, our customers. While we regularly report to our shareholders, our three state regulatory commissions and other agencies, I always look forward to sharing our Community Works Report with our customers and all of our stakeholders in the outstanding part of the country we are privileged to serve.

OUR COMMITMENT TO SAFETYEvery year, NorthWestern Energy promotes pipeline awareness and safety through mailings, trainings, booklets, flyers and education materials.

We also conduct on-going inspections of our natural gas infrastructure, looking for signs of leaks and corrosion.

NorthWestern owns and operates 9,373 miles of natural gas pipelines. The safety and integrity of these pipelines is our top priority.

OUR ENVIRONMENTAL STEWARDSHIPNorthWestern Energy is committed to protecting the environment. We are vigilant in monitoring the impacts of our operations on the environment and managing the natural resources under our stewardship.

In 2019, NorthWestern Energy is providing $1.59 million to support 57 fisheries, wildlife and habitat improvement projects within the 550‑mile corridor of the Madison‑Missouri River from Yellowstone National Park to the headwaters of Fort Peck Reservoir.

RECREATIONNorthWestern participates in a public-private partnership to provide public recreation opportunities along the Missouri and Madison rivers. The Missouri-Madison River Fund is a $6.7 million trust fund for public recreation, the earnings from which fund recreation improvement projects.

Since 2007, the River Fund has awarded nearly $4.5 million that NorthWestern has matched partially with a $1.25 million contribution in support of 126 projects. In addition to this amount, agencies and private partners have made contributions of $3.4 million resulting in more than $9 million in recreation enhancements in the Missouri-Madison Corridor.

In April 2018, NorthWestern Energy purchased the Two Dot Wind Farm, a 9.7-megawatt wind project in central Montana. In addition to lowering customers’ costs, the purchase also complies with the Community Renewable Energy Project component of Montana’s Renewable Portfolio Standard.


2019 RIVER FUND PROJECTS INCLUDE: 6 Replace the ADA-access ramp to the administrative building at Devil’s Elbow Recreation Area on Hauser Lake.

6 Replace the boat ramp at Rainbow Point Boat Launch on Hebgen Lake.

6 Install a shade sail over an outdoor use area at the Lewis & Clark Interpretive Center in Great Falls.

6 Remove a large, unstable dock piling at the White Sandy Recreation Area boat launch.

6 Construct a bridge to allow for storm water drainage on the River’s Edge Trail in Great Falls.

6 Purchase an off-highway utility vehicle for Montana Fish, Wildlife & Parks to perform patrols and visitor rescue on a conservation area in Great Falls.

6 Repair the canoe launch and extend the launch dock at West Bank Park in Great Falls.

6 Add gravel to new campsites at Spring Creek Campground on Hebgen Lake.

6 Construct an ADA-accessible fishing pier at Black Sandy State Park on Hauser Lake.

6 Repair damage to the Roe Island wall and sidewalk at Giant Springs State Park in Great Falls.

6 Install wildlife viewers at West Bank Park in Great Falls.

6 Construct a host site in the camp area at Craig Fishing Access Site on the Missouri River.

6 Support site clean-up and road rehabilitation at Ulm Bridge Fishing Access Site on the Missouri River.

6 Purchase and permanently display a dugout canoe at Missouri Headwaters State Park.

The O’Dell Creek restoration and preservation project, near Ennis, Mont., has been a long-time initiative of area ranchers. With the financial support of NorthWestern Energy, the creek now delivers cleaner, colder water into the Madison River and provides important wetlands for birds and fish.


COMMUNITY PROJECTSLED StreetlightsNorthWestern Energy is in the process of replacing existing street lights with new, energy-efficient LED lights. We will replace some 43,000 company-owned streetlights in Montana with LED lights by 2022.

LED streetlights use about 50 percent less electricity than traditional high-pressure sodium lights, and last two to three times longer. NorthWestern Energy will recycle all parts of the old streetlights, including the metal heads, the glass lenses and the bulbs, which contain mercury.

For more information on all our environmental programs and initiatives, see our Environmental Stewardship Report.

Missoula schools solar projectNorthWestern Energy is working with Missoula County Public Schools and the city of Missoula to install solar panels at Hellgate, Sentinel, Big Sky and Willard high schools. The $1 million pilot project, to be entirely funded and maintained by NorthWestern Energy, is part of the company’s large-scale studies around creating renewable energy solutions that can meet the demands of the national energy grid.

MCPS students and teachers will play a key part in these studies, providing for hands-on learning experiences that will prepare students for jobs and help ensure a sustainable future.

Smart metersNorthWestern Energy is in the process of installing approximately 65,000 electric smart meters in South Dakota and 95,000 smart gas modules in South Dakota and Nebraska. Smart meters meet changing customer expectations by providing two-way communications between electric and gas meters and NorthWestern Energy, allowing better management of individual customer’s energy needs and overall improved customer service. They also allow for quick detection of outages and faster responses to those outages.

ENERGY CONSERVATION OVERVIEWFor the past 40 years, NorthWestern Energy has worked with customers to promote wise and efficient use of electricity and natural gas. We offer programs and energy efficiency information under the NorthWestern Energy sub-brand of Efficiency Plus, or E+. Current programs include rebates and custom incentives for qualifying commercial and industrial facilities, and free energy audits for qualifying homes and small businesses.

Through a contract with the Montana Department of Public Health and Human Services, homes of income-qualified customers receive free weatherization services. A few small-scale renewable projects at non-profit and government/public buildings also receive incentives funded through the USBC.

61,927,680 KWH total electric energy savings in 2018*

868,699 THERMStotal gas energy savings in 2018*

$13.7 MILLIONsaved through energy conservation*

*We base all savings and expenditures on a July 1, 2017 – June 30, 2018, tracker year to Montana. Currently, we do not offer energy efficiency program to our South Dakota or Nebraska customers and rebates are not available to Montana residential customers. Savings and expenditures include Montana small‑scale renewables, energy audits for homes and businesses, and low‑income weatherization funded through the Universal System Benefits (USB) program. We fund additional Montana activities for local conservation, market transformation, research and development, and low‑income bill and energy assistance with USB dollars but those expenditures are not included in this total.

NorthWestern Energy offers free Home Energy Audits to our Montana customers. Energy auditors perform appliance inspections, look for areas of air leakage and offer customers education on how lifestyle and habits affect energy use. Qualifications apply. Montana customers only.


RELIABILITYWhile power outages are unavoidable, we are dedicated to keeping the disruption to a minimum. As such, we monitor and measure the frequency and duration of outages through industry-accepted performance standards called SAIFI and SAIDI.

2015 2016 2017 2018

SAIFI (occurrences) 1.214 1.080 1.289 1.08

SAIDI (minutes) 123.15 107.09 133.49 101.98

Avg. wait (CAIDI) (minutes to get power back)

101.42 99.18 103.54 94.12

OUR RELIABILITY TERMS:

SAIFI (System Average Interruption Frequency Index) - The number of sustained outages (a power outage lasting longer than 5 minutes) experienced by the average customer in a year.

SAIDI (System Average Interruption Duration Index) - The cumulative duration of sustained outages experienced by the average customer in a year.

ADVISORY PANELSNorthWestern Energy actively seeks collaborative input from stakeholders.

In early 2018, we formed the Customer Vision Stakeholder Group to discuss the Montana rate review and the vision for success for NorthWestern Energy in coming years. The group includes representatives from renewable energy groups, the Montana Public Service Commission, the Montana Chamber of Commerce, state and local government, and businesses from across the state.

NorthWestern launched a comprehensive community engagement process to select a site and design for a new substation in the Big Sky service area. That process resulted a site and substation design that met the community’s concerns and desires, as well as the company’s needs.

No matter the weather, anytime there is a power outage, our crews respond quickly to fix the problem and keep disruption to a minimum.


We have continued five years of progress in residential customer satisfaction scores, with our overall customer satisfaction score increasing 14 points from 696 to 710 in 2018, as measured by J.D. Power; once again our highest score to-date.
