Getting to know us Our company is named after the Otter Tail River, which provided our first source of electricity when we became an operating utility in 1909. Hundreds of years ago the Ojibwe noted that a large sandspit follows the contour of the shoreline of a lake where the river flows into it. Because they thought this sandspit resembled the tail of an otter, the Native Americans named the lake Nigagwanoe, Otter Tail. By doing so, they also named a river, a village, a township, a county, and a power company.

Operations
ottertail.com
Otter Tail Corporation In the late 1980s, faced with limited growth opportunities in our electric utility operations, Otter Tail Power Company implemented a diversification strategy designed to provide shareholders with dependable long-term earnings growth. In 1989 we formed Mid-States Development, later named Varistar, to own and oversee the new diversified businesses. In 2001, to better recognize our new enterprises while preserving our well-established brand, we changed the corporate name to Otter Tail Corporation. In 2009 Otter Tail Corporation restructured as a holding company, a business-asusual change for shareholders, customers, and employees. In the restructuring, Otter Tail Corporation became the parent company of Otter Tail Power Company, which operates the regulated utility business, and Varistar, which holds our diversified businesses. This legal structure mirrors historical and ongoing operating structure. Otter Tail Corporation’s objective is to derive 75 percent to 85 percent of earnings from Otter Tail Power Company and between 15 percent and 25 percent from its diversified businesses. This is consistent with the corporation’s strategy to optimize its portfolio of companies, reduce risk, and create a more predictable earnings stream to support the dividend and future growth.

Generation mix
otpco.com/generation
We balance resources to provide our customers with reliable, affordable, environmentally responsible energy.
Integrated Resource Plan In December 2014 we received an order from the Minnesota Public Utilities Commission (MPUC) approving our 2014-2028 integrated resource plan (IRP) with modifications. The IRP grants the authority to add approximately 200 megawatts (MW) of natural gas capacity, up to 300 MW of wind additions, and approximately 28 MW of solar additions. It identifies the most cost-effective combination of resources for meeting our customers’ needs for reliable electric service during the next 15 years. To develop the IRP, we evaluate available electric generation resources and select a plan based on reliability, affordability, achievability, and environmental responsibility. We continue to make existing generating facilities as efficient and economical as possible. But because existing resources alone cannot meet our customers’ future energy needs, the IRP provides a mix of additional resources. While this filing is required only in Minnesota, we develop a strategy for our system as a whole and provide copies of the plan to the North Dakota and South Dakota regulatory commissions.
Hoot Lake Plant retirement and planned replacement In 2012 the MPUC ordered us to complete a baseload diversification study with focus on evaluating retirement and repower options for our aging Hoot Lake Plant. Our study results showed that the lowest-cost option would be to add equipment to comply with Mercury and Air Toxics Standards by 2015 and subsequently retire the plant in 2021. That was our recommendation, and the MPUC approved it. We plan to replace Hoot Lake Plant with a new 200-MW natural gas facility within our service area.

Solar power and renewable energy standards In 2013 Minnesota legislators enacted a solar energy standard that requires investor-owned utilities to supply 1.5 percent of their Minnesota retail electric sales with solar energy by 2020. Our IRP calls for 28 MW of installed solar generation, which is enough to comply with this standard. We’ll meet most of the standard with a utility-scale solar installation. As required, we expect to meet at least 10 percent of the 1.5 percent with solar photovoltaic installations that are 20 kw or smaller. Minnesota also has a renewable energy standard that requires 25 percent of retail sales be generated from renewable resources by 2025 with stepped implementation of 17 percent by 2016 and 20 percent by 2020. North Dakota and South Dakota have renewable energy objectives of 10 percent by 2015. With resources already in service and the planned resources included in our IRP, we expect to have renewable energy in excess of these standards.

Environmental stewardship
Known for their work ethic, honesty, and regard for this area’s natural resources, our employees call our service area home, as do many Otter Tail Corporation shareholders. And because a wholesome environment is essential to a satisfying quality of life, we place respect for the environment at the forefront of our operations. We want our communities and their surroundings to have clean air, land, and water resources. We want them to support wildlife, wildflowers, fish, and local parks. Those are some of the reasons why our Environmental Services Department ensures that we comply with all environmental laws.
Our commitment to air quality
Our company has a long-standing commitment to reduce air emissions. Since 1985 we’ve invested approximately $293 million in environmental-control upgrades and efficiency improvements at our fossil fuel plants. By 2020 we project that we’ll invest another $67 million to comply with U.S. Environmental Protection Agency (EPA) regulations. Since 2007 we’ve invested more than $300 million in wind energy, a zero-emission resource that further reduces our emission intensities systemwide.
Big Stone Plant air-quality control system A groundbreaking ceremony in April 2013 launched a three-year $384 million project at Big Stone Plant to install a new air-quality control system (AQCS) to comply with EPA and state requirements. Otter Tail Power Company owns 53.9 percent of the plant, so our share of the investment is approximately $207 million. We plan to have the system operational in mid-2015, almost two years ahead of the spring 2017 compliance deadline. After the project is complete, we expect a 90 percent decrease in sulfur dioxide (SO2) and nitrogen oxides (NOX) emissions and a more than 80 percent decrease in mercury emission.
BigStonePlantAQCS.com Just how big is the AQCS project? To help put the magnitude of this project into perspective, the information below provides some construction numbers from March 18, 2013, to July 18, 2014. • Reinforcement steel placed: 160,000 pounds • Concrete installed: 11,500 cubic yards • Structural steel erected: 5,000 tons • Loads of material: 1,080 semi-trucks • Largest crane lift (to date): 426,000 pounds In April 2015 the project’s total labor hours reached more than two million—with only one lost-time accident. That’s pretty incredible for a project of this scale.

Since 1985 our tons of sulfur dioxide (SO2) emissions and our SO2 emissions intensity have declined significantly. Total emissions have decreased by 53 percent, and emissions intensity has decreased by 71 percent. Fuel switches from lignite to low-sulfur subbituminous coal at Hoot Lake Plant and Big Stone Plant contributed to the trend along with other plant efficiency projects. Also, the Coyote Station scrubber removed 60 percent of the SO2 in the exhaust gases during 2014. Completion of the new AQCS at Big Stone Plant and replacing Hoot Lake Plant with natural gas generation will lead to fewer SO2 emissions.

Improving power plant efficiency reduces emissions because it takes less fuel to produce the same amount of energy. Net plant heat rate (NPHR), most commonly expressed as Btu/kwh, represents a measure of the amount of energy it takes to produce one kilowatt-hour of electricity. Our change from burning lignite to subbituminous coal at Hoot Lake Plant in 1988 and at Big Stone Plant in 1995 contributed to our NPHR improvement. Subbituminous coal has higher heat content than lignite, so it takes less subbituminous coal to produce an equivalent amount of energy. From 1985 to 2014 we have improved our system average NPHR by more than 26 percent, from 11,588 Btu/kwh to 8,490 Btu/kwh. That average includes owned generation sources and long-term wind power-purchase agreements. We’ve achieved these efficiency improvements in the midst of an almost 60 percent increase in generation from 2,450 gigawatt-hours (gwh) in 1985 to 3,902 gwh in 2014.

The graphs in this section illustrate our past, present, and future commitment to reducing emissions and improving our power-production efficiency. The graphs reflect the total production rate of our system, which includes all of our fossil fuel plants and renewable energy resources. Emissions data are presented both in terms of emissions intensity (pounds of substance emitted per megawatt-hour of electricity produced) and tons emitted.
Hoot Lake Plant reduced its nitrogen oxides (NOX) emissions by approximately 60 percent by installing low-NOX burners and a separated over-fire air (SOFA) system for Unit 3 in 2006 and Unit 2 in 2008. This led to a clear improvement in our NOX emissions intensity when combined with a new SOFA system at Big Stone Plant in 1997. The AQCS project at Big Stone Plant, planned installation of a SOFA system at Coyote Station by mid-2018, and replacing Hoot Lake Plant with natural gas generation will further enhance these improvements.
Carbon dioxide Our efforts to increase plant efficiency and our early renewable energy additions have reduced our carbon dioxide (CO2) intensity. Between 1985 and 2014 we decreased our overall system average CO2 emissions intensity 30 percent. We plan to reduce it further by replacing Hoot Lake Plant with natural gas generation in the 2020 timeframe.

Using water resources responsibly Steam generation requires access to large volumes of water. Our plants fully comply with regulations governing the use of regional water resources as set forth in our water permits. We take great care to ensure that we do not negatively impact the rights of other users. That policy has served us well and has helped ensure a balance between environmental and economic interests.
Coyote Station Coyote Station appropriates water from the Missouri River under a permit issued by the North Dakota State Water Commission. The plant uses a cooling tower to meet its cooling needs. A small portion of the water appropriated for cooling tower operation is discharged to the Missouri River under a permit approved by the North Dakota Department of Health. The remaining plant wastewater is recycled and used in other plant processes. Most of the water lost is through evaporation. In 2014 Coyote Station appropriated 4,422 acre-feet of water from the Missouri River and discharged 370 acre-feet. Heated water is vital for oil extraction in western North Dakota. An independent company, Central Dakota Water Works (CDWW), obtained its own waterappropriations permit from the North Dakota State Water Commission, and Coyote Station uses a water transfer station built in 2012 to fill trucks with water heated by waste heat from our generation process. Coyote Station provided almost 50 million gallons of heated water to CDWW in 2014.
Big Stone Plant Big Stone Plant withdraws water from Big Stone Lake under a permit granted by the South Dakota Department of Environment and Natural Resources (DENR). The permit includes restrictions that limit water withdrawals when the lake is below prescribed levels. During 2014 we withdrew 2,752 acre-feet of water from Big Stone Lake. Water used at Big Stone Plant is treated and eventually recycled back into the plant and to an adjacent ethanol plant. This unique cooling-water design allows the plant to not discharge heated water or process water into any natural body of surface water.
Hoot Lake Plant The Minnesota Pollution Control Agency (MPCA) oversees water-quality programs and discharge regulations at Hoot Lake Plant. The Minnesota Department of Natural Resources administers water appropriations. Water for the plant comes from nearby Wright Lake and is classified as either consumptive or nonconsumptive. Nonconsumptive water is returned to the Otter Tail River under the plant’s water discharge permit, while consumptive water is consumed within the plant. During 2014 nonconsumptive use totaled 53,683 acre-feet of water, and consumptive use totaled 1.29 acre-feet.
National Pollutant Discharge Elimination System permits National Pollutant Discharge Elimination System (NPDES) permits cover the return of public waters to their watersheds. The states where we do business issue the required NPDES permits. In 2012 we submitted a permit application for Hoot Lake Plant’s industrial waste water and storm water. We expect to receive the renewed permit in 2015. In 2013 Coyote Station’s Industrial Wastewater Permit and Big Stone Plant’s General Storm Water Permit were renewed. In 2014 our company’s General Office Summertime Cooling General Water Permit was renewed. Industrial use of public waters is essential to our operations, and compliance with our permits is critical.

Protecting wildlife
Hoot Lake Plant wood duck nesting boxes We relocated an ash site near Hoot Lake Plant and restored the area as a flood plain along the Otter Tail River. As part of the restoration project, we worked with the Minnesota Department of Natural Resources to provide suitable spawning and nesting habitat. The Fergus Falls Fish and Game Club provided new wood duck nesting boxes, which we installed along the river to improve the wood duck population.
Osprey nesting platforms About ten years ago a breeding pair of ospreys, large raptors with wingspans of more than 60 inches, began constructing a nest on an electrical pole near Big Stone Plant. To keep these rare birds safe and away from energized lines, employees erected a nesting platform, which has been used for several years. In July 2013 a second pair of ospreys began nesting on an electrical pole near the first nesting platform. So, employees erected another nesting platform. In 2014 ospreys used both nesting platforms. Because ospreys typically return to the area where they were hatched to start their own families, Big Stone Plant employees are looking forward to continuing to watch these beautiful birds.
Addressing spills, fines, and sanctions
Despite our commitment to sound environmental stewardship, rare mistakes and uncontrollable events occur. When they do, we correct them as quickly as possible.
Spills On October 25, 2013, the leachate collection tank at Hoot Lake Plant overflowed, and approximately 718 gallons of coal ash leachate overtopped a containment dike. Some of the leachate absorbed into the surrounding ground, and some made its way into the Otter Tail River. We reported the overflow to the Minnesota Pollution Control Agency (MPCA), took immediate corrective actions, and implemented changes at the plant to prevent similar occurrences. In 2013 and 2014 equipment failures caused minor oil spills. The two most significant spills involved a failed hydraulic oil line on a backhoe and a ruptured diesel fuel line. We promptly report and clean spills.
Fines and sanctions We paid a $2,050 fine to the MPCA in response to the leachate overflow described above. No other fines have been assessed to our company for environmental infractions.

Monitoring regulatory proposals
Coal-fired plants are subject to a multitude of regulations that the EPA either has promulgated recently or is in the process of revising. The exact impact of these rules is difficult to predict because challengers typically question through court action whether the EPA is adhering to key restrictions and obligations. The outcome of these challenges notwithstanding, regulatory uncertainty will continue to impact our planning and operations. We are paying particular attention to the following rules that the EPA is developing or has recently developed.
Coal Combustion Residuals Rule Regulatory background In June 2010 the EPA proposed regulating coal combustion residuals (CCR) as either hazardous or nonhazardous waste. In December 2014 the EPA signed a final rule categorizing CCR as nonhazardous waste under Subtitle D of the Resource Conservation and Recovery Act (RCRA). The new rule is self-implementing, which means the rule relies on citizen and state involvement with no federal enforcement. Highlights of the rule include: Establishing a web page with information about the design, operation, environmental monitoring, and corrective actions required at CCR landfills and surface impoundments. Installing additional environmental monitoring equipment, such as groundwater monitoring wells. Evaluating previously unpermitted sites to ensure their conformance with the new rule. Designing landfill and surface impoundment liners and capping systems to one national standard. Closing unlined surface impoundments if groundwater monitoring indicates a statistically significant increase of chemical concentrations above the background levels for the unit. Even though the EPA has chosen to regulate CCR under Subtitle D, it reserves the right to regulate the material under Subtitle C as more data becomes available. We’ve begun taking the necessary steps to maintain compliance with this new rule and will continue following the EPA’s rule-making process. Otter Tail Power Company impact We’ll evaluate our CCR units, both landfills and surface impoundments, to ensure conformance with the new rule. We’ll develop a new web page that will allow the public to quickly access information about the design, operation, maintenance, and environmental monitoring of our CCR units. Additional environmental monitoring will be required at several sites. As we expand landfills or ponds, we’ll incorporate national standards in their designs.
Challenges The EPA’s withholding of the final classification of CCR is our most significant challenge. The EPA still may propose more stringent and expensive disposal options. Additional challenges include determining applicability of potential CCR units in conformance with the new rule, assessing environmental monitoring systems, installing additional monitoring equipment, and establishing a public web page.

The EPA signed BiggasStone replaced with 211 MW of single-cycle natural gas generation in 2021. a final rulemaking termed the Mercury and Air Toxics Standards (MATS) rule in December 2011. The MATS rule sets standards for mercury and other air toxics that units must attain by monitoring and meeting a 30-day rolling average, quarterly testing, or adhering to work practice standards. Power plants had until April 16, 2015, to comply, although the Clean Air Act does provide that sources may be granted up to one additional year for compliance if such time is necessary for installing controls.
Otter Tail Power Company impact Our units will meet the requirements by installing the AQCS at Big Stone Plant, upgrading the electrostatic precipitators at Hoot Lake Plant, and adding mercury emission-control equipment at all coal-fired plants. Big Stone Plant was granted up to an additional year to comply to align the installation of the MATS control equipment with the AQCS project. Emissions monitoring equipment and/or stack testing also will be necessary to verify compliance with the standards. The graph above shows the anticipated decrease in our mercury emissions after complying with MATS. Challenges Although the rule presents several new complexities and costs, we’re prepared to meet the rule’s compliance deadline.
Transport rule for sulfur dioxide and nitrogen oxides Regulatory background The Clean Air Act requires the EPA to address interstate transport of air pollution. Consequently, in 2011 the EPA issued a rule termed the Cross-State Air Pollution Rule (CSAPR) to reduce SO2 and NOX in 23 states, including Minnesota. After having been reviewed in proceedings at the D.C. Circuit Court and the Supreme Court, the rule applies in 2015 and requires units to manage a new set of SO2 and NOX emission allowances (i.e., a cap-and-trade program). Otter Tail Power Company impact Because the CSAPR region only includes Minnesota, Hoot Lake Plant and the Solway combustion turbine are our only facilities to which the rule applies. Based on the emission allowances that the EPA has allocated, we’ll need to purchase allowances for Hoot Lake Plant. Challenges Allowance purchases will result in additional costs for our customers.

Environmental stewardship
Regional haze Regulatory background The EPA promulgated the Regional Haze Rule in 1999 to address visibility impairment in Class I areas. Class I areas include 156 national parks and wilderness areas, such as the Boundary Waters Canoe Area and Voyageur’s National Park in Minnesota. States have submitted plans detailing their strategies to reduce haze and setting reasonable progress toward the goal of no man-made visibility impairment in Class I areas by 2064. Otter Tail Power Company impact The Regional Haze Rule includes a provision that sources built between August 7, 1962, and August 7, 1977, found to contribute to visibility impairment in Class I areas must install best-available retrofit technology (BART). Big Stone Plant and Hoot Lake Plant Unit 3 were built within this timeframe. Air-dispersion modeling determined Hoot Lake Plant Unit 3 did not significantly contribute to visibility impairment and thus is not subject to BART. However, modeling for Big Stone Plant indicated that its emissions reasonably contribute to visibility impairment in Minnesota, North Dakota, South Dakota, and Michigan. The new Big Stone Plant AQCS will address this impairment. Although not subject to BART, Coyote Station is required to make NOX reductions as part of North Dakota’s need to achieve 2018 reasonable progress goals. Separated over-fire air controls (SOFA) will allow Coyote Station to achieve necessary NOX reductions. Challenges States must revise their regional-haze plans by July 31, 2018, and every ten years thereafter. These revisions may impose additional emissions reductions over time. Because these reductions are determined on a case-by-case basis and require EPA approval, it’s difficult to predict the stringency and timing of future controls.
Carbon dioxide regulations Regulatory background In September 2013 the EPA announced proposed standards under Section 111(b) of the Clean Air Act to limit carbon dioxide emissions from new power plants. In June 2014 the EPA announced a proposed rule under Section 111(d) of the Clean Air Act to regulate carbon dioxide emissions from existing power plants. The 111(d) rule, often termed the Clean Power Plan (CPP), imposes varying CO2 emissions intensity limits on each state. Otter Tail Power Company impact We’re concerned about some of the technical missteps in the proposed CPP. We believe the Clean Air Act assigns states the lawful authority to establish 111(d) standards of performance and unit-specific emission-reduction targets, but not state-specific targets. By failing to allow the states this authority, the proposed CPP results in proposed state targets that often misapply key baselines and require emission-reduction strategies that don’t work under current industry and regulatory constructs.
In 2013 we conducted a largescale drill to test the Pisgah Dam Emergency Action Plan (EAP). During the drill, responders reacted to a preplanned scenario in which a call to the 911 dispatch center reported the dam failing and a fisherman being swept downstream. The fire department search-andrescue crew located a dummy hidden downstream and brought it to safety. Police, ambulance, and other emergency personnel also were deployed in this mock emergency. The drill also included simulations of a traffic accident, traffic rerouting, and closing of Interstate 94. The drill is a requirement of the Federal Energy Regulatory Commission because of the dam’s downstream proximity to a wastewater treatment facility, Interstate 94, and homes. According to hydrological and geological studies, however, an overtopping or failure of the dam would have little or no impact on downstream homes. All parties found the drill beneficial, and the EAP was revised as a result.
Our most significant concerns pertain to the proposed CPP’s impact on South Dakota and Big Stone Plant. The EPA’s proposed redispatching methodology between Big Stone Plant and natural gas generation isn’t technically feasible in South Dakota. And the EPA should not overlook the significant investment being made by the Big Stone Plant co-owners to comply with other EPA rules.
Environmental stewardship
19
Challenges We submitted extensive comments on November 24, 2014, requesting the EPA to address the technical missteps in the proposed CPP. The EPA is evaluating more than 2 million submitted comments and expects to finalize the rule during the summer of 2015. We look forward to a final rule that addresses our concerns.
Cooling water intake structures Regulatory background In May 2014 the EPA signed the final 316(b) rule for cooling water intake structures (CWIS). The rule requires that the location, design, construction, and capacity of a CWIS reflect the best technology available (BTA) for minimizing adverse environmental impact. Adverse impact results from withdrawing cooling water containing aquatic organisms and subsequent impingement of larger organisms on the intake structure or the entrainment of smaller organisms within the plant cooling-water system. The rule only applies to facilities with National Pollutant Discharge Elimination System (NPDES) water discharge permits. Thus, Hoot Lake Plant and Coyote Station will be subject to the rule. Our Put your paper to better use campaign encouraged customers to enroll in ePay, our free electronic billing program. In return for each new customer enrollment, we made a $3 donation to an area nonprofit organization. In 2014 we donated $14,800 to the nonprofits listed below as a result of new customer enrollments. • March through June: The International Music Camp in North Dakota

Environmental stewardship
Otter Tail Power Company impact Under the rule, all regulated facilities will need to comply with one of several BTA alternatives for reducing mortality of aquatic organisms due to impingement and entrainment. To comply, Coyote Station will use the closed-cycle cooling option, and Hoot Lake Plant plans to use the de minimus option. With the de minimus option, facilities with very low levels of impingement aren’t required to employ any additional impingement controls. State permitting authorities ultimately will determine the compliance option most appropriate on a site-specific basis. States also will decide site-specific BTA for entrainment. Closed-cycle cooling is considered a possible BTA for reductions in entrainment mortality. Regardless of which BTA option a facility chooses for compliance, all facilities with NPDES permits must submit numerous studies with their next permit renewal application to support the determination of site-specific BTA. Challenges Each impingement compliance alternative comes with its own set of sampling and monitoring requirements. As a facility with closed-cycle cooling, Coyote Station likely will need to monitor only intake, makeup, and blowdown flows on a daily basis as well as cycles of concentration of its cooling towers. Requirements for Hoot Lake Plant are less clear. If the State of Minnesota agrees to the de minimus option, Hoot Lake Plant may not need to do anything further to demonstrate compliance. Compliance deadlines Compliance deadlines are largely dependent on NPDES permit renewal dates. In general, the rule requires that we submit an application during the next renewal cycle for permits that expire more than 45 months after the final rule becomes effective, which is around July 2018. Coyote’s current permit expires in March 2018, so it’s eligible for an alternate compliance timeline at the discretion of the State of North Dakota. If North Dakota doesn’t grant us an alternate timeline, we may need to submit all studies by September 2017. Hoot Lake Plant’s NPDES permit expired in 2012 and has been in renewal status for the last three years, so it’s unclear when we’re required to submit its permit application studies.
Promoting energy efficiency
We believe that an electric utility should share employee expertise with its customers and communities. We offer customers proven energy-efficient technology options, rate information to help them calculate their operating costs, and energyefficiency programs to meet customers’ goals and needs. We continue to pursue aggressive energy-conservation goals and in 2014 again offered a portfolio of conservation programs in Minnesota and South Dakota.
Minnesota Conservation Improvement Program Our Minnesota Conservation Improvement Program (CIP) offers customers the opportunity to save energy and money. Benefits extend to all customers through deferred utility infrastructure investments and less energy consumed. We designed our 2014 CIP programs to comply with The Next Generation Energy Act of 2007. The Act sets an aggressive statewide energy-conservation goal of 1.5 percent of average annual Minnesota utility retail sales. We introduced new programs and focused additional resources on implementing the CIP programs to achieve this goal. During 2014 we invested more than $5.18 million in CIP and returned more than $31.2 million in lifetime benefits to customers. Savings reached an estimated 33.8 million annual kilowatt-hours (kwh) of energy and more than 10.5 MW of demand. For the year, that is 1.62 percent of our annual retail sales. At a lifetime cost of less than 2 cents per kwh conserved, our energy-efficiency programs continue to be a cost-effective resource for customers. In addition to designing programs to meet conservation goals, we’re working to ensure that savings estimates are measurable and verifiable to meet stringent state program requirements. While 2014 savings results had not yet been approved when this report went to press, we highlight a few of the more than 30 Minnesota programs offered in our CIP portfolio. Energy-efficient lighting Our commercial lighting retrofit program continues as one of our most successful commercial energy-efficiency programs. In 2014 more than 582 participants installed systems that are expected to save approximately 8.09 million kwh annually during the life of the technology. In new-construction lighting applications, 128 participants saved 2.17 million kwh by selecting high-efficiency lighting options. With our Be Bright program, we partner with local retailers to offer our residential customers point-of-sale rebates on Energy Star-qualified compact fluorescent lightbulbs (CFLs) and LED lighting. As part of a new program, we donated CFLs to local nonprofit organizations, including schools, community theaters, and fire departments, to sell to our residential customers in targeted communities. The organizations retained 100 percent of the proceeds. Together, our Be Bright and nonprofit fundraising programs resulted in distributing 111,329 CFLs and LEDs that we estimate will save more than 4.38 million kwh annually during the life of the bulbs. Heat pump rebates Rebates encourage customers to replace their less efficient heating and cooling systems with air-source or geothermal heat pumps. The program, which saved nearly 2.2 million kwh in energy sales for the year, is designed to reduce both winter and summer peak demands as well as overall energy use. Approximately 139 residential and 59 commercial high-efficiency and Energy Star-rated equipment installations qualified for rebates. Environmental stewardship

Energy-efficient equipment grants Our Custom Grant Program taps the conservation and efficiency potential of commercial and industrial operations by partially funding cost-effective energyconservation projects. We make customized grant awards based on our analysis of the projected energy-saving benefits to be derived from proposals developed and submitted by customers. During 2014 we provided 37 custom grants to customers for industrial and manufacturing installations of energy-efficient process improvements with a total projected savings of about 2 million kwh of energy and 466 kw of demand. Motor and adjustable-speed drive rebates Motors can account for up to 75 percent of the total electricity costs in industrial plants and up to 50 percent of electricity costs in commercial buildings. Replacing used or burned-out standard-efficiency motors with energy-efficient motors reduces energy use and operating costs. One method to manage motor operation is installing adjustable-speed drives (ASDs) that improve system performance and energy efficiency. During 2014 our customers installed and received rebates for 161 efficient new, replacement, or retrofit motors and 150 ASDs with projected savings of 6.2 million kwh of energy and 1,054 kw of demand.
Barrel O’Fun®, a division of KLN Family Brands, participated in our Industrial Process Efficiency program. After benchmarking internal energy-management practices, an engineering study identified ten energy-saving projects. The first project implemented was upgrading the facility’s lighting to LED technology. The company expects the upgrade to reduce its annual energy costs by $27,000 and expects a return on investment in less than two years.
Industrial Process Efficiency We’re now offering an Industrial Process Efficiency program to help our largest customers identify opportunities to reduce their energy use. We work with these customers to benchmark their energy-management practices, identify efficiency improvements through an engineering study, and provide rebates and incentives for implementing efficiency measures. The potential energy savings of this program are significant with just 1.3 percent of our customers using nearly half of the retail energy we sell.
CoolSavings Residential customers who enroll in CoolSavings earn a $7-a-month bill credit June through September in exchange for permitting us to cycle their central air conditioners 15 minutes on and 15 minutes off during peak periods. We offer this program to residential customers across our service area because of its combined energy savings and summer-season load-management benefits. During 2014, 111 of our Minnesota customers, including 39 units for commercial customers, were enrolled. We’ve expanded the commercial option to other parts of our Minnesota service area to increase participation. Across the three states we serve, approximately 1,366 customers are enrolled. Appliance Recycling Our Appliance Recycling program encourages customers to recycle working but inefficient refrigerators and freezers to receive a $50 rebate. Providing this service across our large, wide-spreading service area was a challenge met by our service provider, Appliance Recycling Centers of America. By working with a service provider that also serves other utilities, we’ve been able to maintain cost-effectiveness. In 2014 the program recycled and rebated 449 appliances. House Therapy Our House Therapy program continues to offer income-qualified customers compact fluorescent lightbulbs, controlled water heating, and refrigerator and freezer replacement. Customers with electricity as their primary heat source are eligible for home weatherization services, including weather stripping and insulation. Offered through a partnership with Minnesota Community Action Agencies, this program served 34 homes in 2014.

Student energy kits We worked with Great Plains Natural Gas and Lake Region Electric Cooperative on a program to distribute 500 energy kits to middle school students. The kits contained CFL and LED bulbs, engine block heater timers, faucet aerators, and low-flow showerheads, as well as information about these products and installation instructions. After the students took the kits home, we asked them to complete and return a survey about their installations. The classes with the highest percentage of returned surveys won a pizza party. Through this program, the three participating utilities overall saved more than 500,000 kwh, and our customers saved about 337,657 kwh and 24.5 kw of demand. Energy Feedback Personalized energy-use information drives behavior, and behavioral changes produce energy savings. Built on those facts, our Energy Feedback program delivers energy-use information to customers by mail through Opower Home Energy Reports and online through the AclaraŽ Home Energy Analyzer tool. The program is a successful and significant part of our residential portfolio of conservation programs. Approximately 31,000 residential customers were selected for inclusion in the Home Energy Report program. Throughout 2014 each household received up to seven reports that outlined how its energy use compared with similar homes in the area. Customers may opt out if the information doesn’t interest them, but about 1 percent have done so. Customer savings averaged 162 kwh per household. Home Energy Analyzer is an online service that customers opt to use. It incorporates bill history and calculator tools that help customers find personalized ways to save. In 2014, 2,829 Minnesota customers saved an average of 692 kwh per household. Overall savings with these two Energy Feedback programs totaled almost 7.6 million kwh in 2014.
Energy efficiency is a component of our IRP Because the Minnesota PUC recognizes energy efficiency as a resource in planning to meet future energy needs, our Minnesota CIP supports our 2014-2028 integrated resource plan (IRP). Approved in October 2014, our IRP calls for 55 MW of new conservation and 15 MW of new summer-season demandresponse capacity through 2028. See page 7 for more information about our IRP.
South Dakota Energy Efficiency Plan Our South Dakota residential and business customers continue to require less electricity because of energy-efficient technologies available to them through our Energy Efficiency Plan (EEP). This conservation plan encourages businesses to install energy-efficient lighting, motors and drives, air-source and geothermal heat pumps, and custom efficiency improvements. The program encourages our residential customers to take advantage of our CoolSavings air-conditioning control program and offers incentives for installing energy-efficient lighting and air-source and geothermal heat pumps.
Our company won the E Source 2014 Demand-Side Management (DSM) Achievement Award for the most energy savings per customer for an electric utility. With average savings of 598 kwh per customer, our Minnesota CIP savings far outpaced other studied utilities, which averaged 255 kwh per customer. Senior Market Planning Specialist Brenda Sandahl (right) accepted the award on behalf of our company from Rachel Reiss Buckley, E Source DSM services director.
Preliminary results for 2014 show that we invested $351,483, returning more than $7.2 million in lifetime benefits for customers. Customer energy savings reached 3.38 million kwh, which was 121 percent of our 2014 EEP goal.
North Dakota energy conservation We continue to offer demand-response programs and incentives to our North Dakota customers. North Dakota regulators have not approved an energyefficiency program.

Social stewardship One element of Otter Tail Power Company’s mission is to improve the quality of life in the areas in which we do business. To that end, we work to have open and timely communication with customers, regulators, employees, shareholders, and others. We engage in our communities to strengthen the viability of our region. We place reliability, cost-effectiveness, and environmental responsibility at the forefront. We are active in the processes that shape utility industry changes. And we have fair business practices that comply with regulatory and legislative policy.
Open involvement
We continue to work with regulatory agencies on the local, state, and federal levels to obtain required project approvals. Through agency and public meetings, project teams make a unified effort to implement processes that are transparent. We hope that one-on-one relationships and communication with our customers and local governing officials help to simplify processes and encourage customer participation. For example, in 2014 interested stakeholders participated in public meetings related to the following projects: Fargo-to-St. Cloud 345-kv transmission line. Big Stone South-to-Brookings County 345-kv transmission line. Big Stone South-to-Ellendale 345-kv transmission line.
Customer information
To help ensure safe and reliable electric service, we provide customers with information about using electricity wisely. Our websites otpco.com and conservingelectricity.com, advertising, bill inserts, and news releases emphasize safe, efficient energy use. Our goal is to ensure that our customers have convenient access to this information. We also use these methods to inform customers about rate options, available financing and rebates, and the services they can obtain from our customer service centers. Our conservation and demand-response programs are cornerstone messages in our advertising. Our 2014 campaigns included: CoolSavings, which encouraged customers to allow us to cycle their air conditioners to help manage summer’s high energy-use periods. More than Ever, which encouraged our business customers to make energysaving improvements by taking advantage of our many rebates and programs. Attic Survivor, which encouraged customers to keep heat where it belongs through insulation and weatherization. Regulatory commissions in the three states we serve require that we share certain information about rates and rate changes with our customers through bill inserts, advertisements, or special mailings. We work closely with the commissions to ensure that we meet their expectations. In 2014, as in previous years, we complied with all regulatory notification requirements. Of course, throughout all communication with us, customers can be assured that their private information is kept confidential. We have a privacy plan that complies with national Red Flags rules, and we regularly train employees about this plan.

Emergency procedures covered in the guidelines include medical, fire, tornado, workplace violence, building evacuation, bomb threat, and suspicious mail and objects. Our Safety Services Department periodically reviews the emergencyresponse guidelines.
Crisis-management plan Our crisis-management plan is a thorough, step-by-step checklist that includes a first-hour response plan, key contacts, and situation-specific procedures for major crises. This plan is reviewed annually by the executive team, area managers, plant managers, attorneys, Otter Tail Corporation, and representatives from our Public Relations, Safety Services, System Operations, Regulatory Services, Environmental Services, and Delivery Engineering Departments.
System-restoration plans In the spring and fall of each year we and our neighboring utilities run drills based on our respective system-restoration plans. The purpose is to exercise the procedures and processes required to restore the bulk electric system from a blackout condition. By understanding system behavior and having jointly developed and proven procedures in place, Otter Tail Power Company and neighboring utilities help ensure continued system reliability for the region. Because reliability is one of our primary concerns, we also maintain a backup control center, which would allow us to work with neighboring utilities if our primary control center were to become unusable.
Enterprise Incident Response Plan Our Enterprise Incident Response Plan is an organized approach to address and manage the aftermath of an incident that may range from a system failure to a cybersecurity attack or a physical security breach. It defines what constitutes an incident and provides a process to follow in a way that limits damage and reduces recovery time and costs.

Reliability
We work hard to minimize the frequency and duration of service interruptions. As part of a long-term reliability strategy, we perform critical analyses of our transmission and distribution systems to identify areas requiring proactive maintenance. Here are our 2013 and 2014 storm-normalized reliability results as recorded by our interruption monitoring system. System Average Interruption Frequency Index (SAIFI): The number of interruptions lasting five minutes or more that an average customer experienced during the year. SAIFI

Cybersecurity Compromises to cybersecurity pose a serious threat to the reliable operation of the bulk power system. To mitigate risk, the Federal Energy Regulatory Commission approved Version 5 of the Critical Infrastructure Protection Cybersecurity Standards (CIP Version 5) in late 2013. To comply with these standards, we’re securing software tools, identifying impacted facilities, and drafting supporting policies. CIP Version 5 requires us to categorize our cyber assets as high, medium, and low impact. Our high- and medium-impact cyber assets need to be in compliance by April 1, 2016, and the low-impact assets must be in compliance when the final CIP Version 5 standards become enforceable on April 1, 2017.
Vegetation management We prune and remove trees on a five-year systemwide cycle, thereby reducing vegetation- and animal-related outages. In 2014 we spent about $1.52 million on vegetation management for our transmission system and about $1.78 million for our distribution system.
Asset Replacement Plan We’re developing a proactive Asset Replacement Plan for our critical assets to improve system reliability, reduce the median age of our assets, and establish adequate funding for the plan to be successful. These critical assets include substation transformers and voltage regulators, circuit breakers, poles, and underground cable. Social stewardship

Customer satisfaction Relationship survey
Since 2004 we’ve engaged the American Customer Satisfaction Index (ACSI) research program to conduct an independent survey among random residential customers. ACSI asks them about all aspects of their service relationships with our company and compares our customer satisfaction ratings with those of the largest energy utilities in the country which, combined, serve more than 75 percent of the nation’s residential customers. We added a few components to our 2014 survey to expand customer feedback, including website satisfaction questions, email surveys in addition to the traditional phone surveys, and a separate survey for our business customers. Our overall relationship satisfaction score among residential customers for 2014 was 85 points out of 100. This was 4 points higher than the highest-rated electric or dual electric/gas investor-owned utility (IOU) and meets our company’s goal of being in ACSI’s top-five-rated utilities. We scored high in every key driver that ACSI measures, including satisfaction, meeting customer expectations, quality, perceived value, customer loyalty, reliability, and service restoration. The overall satisfaction score for our website was 79, which was 4 points higher than the Energy Utilities score of 75, equal to other IOUs, and slightly higher than the National Website Index score of 78.2. Our website loyalty score of 86 compared favorably with other consumer industry scores. 2014 ACSI Relationship Survey results Otter Tail Power Company

Our overall relationship satisfaction score from our business customers is 83 points out of 100. Although ACSI doesn’t have a national benchmark for business customers, as they do for residential, this research will provide us a broader view of all customers’ satisfaction.
Transaction survey We conduct transaction surveys with customers who have contacted our company within a defined period of time. The survey measures transaction-specific customer satisfaction and issue resolution. The survey targets all customer contacts— phone, web, mail, in-person visits, and after-hours calls—and measures the specific aspects of service provided. In 2014 our customers were satisfied with their contact experiences, rating us 9.1 on a 10-point scale. 2014 Transaction Survey results Overall contact experience satisfaction (10-pt scale) - Mean

Community commitment Public safety
Helping keep customers and the public safe always has been paramount to our company. Our Safety Services Department staff, field personnel, and power plant employees give electrical safety presentations for schools, fire departments, and other organizations throughout our service area. These presentations educate the public about the hazards of electricity and about proper electrical safety measures. We also distribute several public service notices related to electrical safety throughout the year to raise awareness. 2014 messages included: Portable electric space heater safety. Ground fault circuit interrupter testing. Call Before You Dig reminder. Summer storm preparation. Electrical safety and flooding. Harvest safety. Hunting safely near electrical facilities. Holiday safety. Winter storm preparation.
Contributions and volunteer work We volunteer our time and skills to make our communities better places to live. Our employees volunteered for a wide range of nonprofit organizations and charitable causes in 2014. They served on boards of directors, organized volunteer projects, and made financial contributions. Power of Two matching gifts program Our Power of Two program furthers this volunteer spirit. Each employee who contributes a minimum of 24 hours of personal volunteer time within the year to a single nonprofit organization is eligible for a $100 donation to that organization. Otter Tail Power Company contributed $5,500 to 41 different organizations in 2014 on behalf of our employees. Community Connections giving program While we provide financial support to a broad array of activities and organizations, we focus our resources on the rural communities we serve. Please read page 37 in the “Economic stewardship” section of this report to learn more about this giving program.
Our company, along with 12 other Minnesota utilities, launched “Slam the Scam” to raise customer awareness about scams aimed at utility customers. The coalition encourages customers who think they are being targeted by a scammer to simply end the conversation and “slam” down the phone if it just doesn’t feel right.

Employee health and safety
We have a comprehensive safety program because the safety of our employees is of utmost importance. We provide safe working conditions, extensive safety training, and appropriate protective equipment. We inspect and upgrade equipment and continue to upgrade work methods. We investigate accidents to determine causes and preventive measures. And we encourage managers to begin meetings with a safety reminder. With these principles and practices, we make safety a commitment on every job site and a focus for every employee. We established a formal safety department in 1949—one of the nation’s first among electric utilities. We consistently have received awards from safety councils in the states we serve for exceptional workplace safety performance. These awards represent the achievements of all employees across all three states. We are proud of our safety tradition, which continues to yield a lower accident and injury rate than our industry peers. Safety performance comparisons Otter Tail Power Company

Hoot Lake Plant partnered with the Minnesota Department of Natural Resources (DNR) to establish a new canoe and recreational tubing portage on the Otter Tail River. Due to its natural bends, a turbulent stretch of the river had been a challenge for recreational users near Hoot Lake Plant. At times of high water, whitewater conditions exist. In September 2014 the team constructed a new portage and added more signage to make the stretch easier to navigate for those who don’t want the thrill of whitewater action.

Cost projections
Weâ&#x20AC;&#x2122;re taking proactive steps to keep the price our customers pay for electricity as economical as possible. New technologies and infrastructure investments, which cost less than other options to produce and move low-cost electricity, will help to keep the price our customers pay among the lowest in the region. And our programs, some of which are mentioned on pages 21-23, can help customers use electricity wisely and save even more. While weâ&#x20AC;&#x2122;ve selected low-cost options to meet customer needs, they still come with a price. Since 2010 weâ&#x20AC;&#x2122;ve been encouraging customers to plan for an overall average bill increase of about 5 percent a year through 2020. We now anticipate that all customers averaged together will see a bill increase of about 3 to 4 percent a year from 2010 through 2020. The increases will vary by state, year, and size. For example, in 2014 customers saw an overall average price increase of about 5 percent.

Commodity costs Maintaining a reliable electrical system requires the ability to access financial markets to finance increasing costs associated with system repairs and updates. Costs for crucial commodities are on the rise nationwide, yet our company has worked to ensure that the electricity we provide remains a value to the homes and businesses we serve.

Load management
Customer participation in our direct load-control rates makes our company unique among utilities. An unmatched one-third of our customers partner with us in load management, allowing us to curtail a portion of their electrical load during periods of high demand, high energy prices, or system maintenance. Participating customers save on their heating and cooling bills with rates that are less than our standard electric price. We accredited with MISO a portion of our direct load-control capacity, making it available on a limited basis during MISO system peaks. The amount accredited varies monthly and is set as 90 MW in January, February, and December; 55 MW in March, April, and November; 25 MW in October; 18 MW in July, August, and September; and 15 MW in May. Accrediting a portion of the demand resources is a step to further enhance regional transmission reliability. Our 2014-2028 IRP calls for demand-side management resources to increase annually through 2028 to reach approximately 15 MW of additional summer-season peak-load-reduction capability. To achieve this, we connected an additional 11 MW of controlled winter-season load and 2.2 MW of controlled summer-season load.
New Customer Information System
Our Customer Information System (CIS) performs billing, processes payments, and manages customer account information such as account balances, payment programs, and participation in demand-side management (load control). We are researching newer systems that are capable of billing increasingly complex rates, providing better workflow, integrating more easily with other systems, and ultimately offering more electronic options to our customers. Weâ&#x20AC;&#x2122;ll select a CIS vendor in the first half of 2015 with the aid of a consultant. If given approval to proceed with implementation from the Otter Tail Corporation Board of Directors, weâ&#x20AC;&#x2122;ll work with the selected vendor to reach a targeted in-service date roughly 2.5 years after implementation begins.
