WESTAR ENERGY 2014 Annual Report Westar Energy.

Taking energy to heart.

WESTAR ENERGY 2014 ANNUAL REPORT Table of Contents Letter to Shareholders 1 2014 Financial Measures 6 Form 10-K 7 Shareholder Information and Assistance 80 Corporate Information 80 Directors and Officers 81 Westar Energy is a power company. We're also Kansans who work every day to create a strongerfuture for our state.

We provide electricity to more than halfour state's population.

That electricitypowers their lives, charges the technology that drives innovation, and empowers them to build a better place

,br everyone. That's how we push Kansasjorward.

Our role in pushing Kansas forward starts with generating electricity, but grows with action in our communities.

We're proud of our commitment to our communities,from supporting science, technology, engineering and math education to the 70 community projects our Westar Energy Green 7eiam tackles each year. This is what it means to take energy to heart and it all starts with our employees. They are the faces of Westar Energy in our communities and play a vital role in making Kansas better.

Dear Shareholders,

We all take for granted the reliability and convenience of electricity. Lights come on at the flip of a switch.

Cell phones, tablets and laptops are charged and ready to keep us connected. Our milk stays cold and our coffee is hot, all thanks to the convenience of electricity. The electricity we generate, distribute and serve has real, tangible value for our shareholders and customers. But we're not in business just to provide electricity, we have a greater purpose. Electricity is what we make but it's not our "why."

Why are we in business? To help push Kansas forward while being good stewards of your investment.

How do we do that? By providing safe, clean, affordable and reliable energy that supports the health and well-being of Kansas communities. We are proud of where we work, where we live and the role we play in Kansas' future, and this translates into a good investment for our shareholders.

Our mission is simple: We power lives - one home, one business, one community at a time - with safe, clean, reliable electricity and the highest dedication to our customers.

We take it to heart every day because we know being a good neighbor isn't just about providing power, it's about the lives we touch and the decisions we make to move our company and your investment forward.

I'm pleased to share our accomplishments in 2014 and plans for 2015.

TAKING CUSTOMERS TO HEART We're honored to be our customers' energy partner.Our goal always is to treat customers with respect, genuinely caring for them. If given a choice, we want them to choose us.

We must continually improve our customers' satisfaction. To get there, our employees have mapped every point where we interact with our customers, from our meter readers to our linemen to our call center representatives. Every month, we bring employees together from across the company to review those interactions, identify pain points for our customers and make immediate improvements as we look at our service through our customers' eyes.

We also leverage technology to make our customer experience better. Everyone is living busier on-the-go lives, so we launched a mobile app this year. The ability to pay bills and change service is at our customers' fingertips with the device of their choice. Our efforts will focus on providing options through which our customers choose how they want to do business with us.

On those occasions where a storm knocks out the power, nothing is more frustrating than being in the dark, not knowing when the lights will come on. Our customers now have access to a new interactive outage map on their phones or tablets, allowing them to hone in on outage areas, right down to their street. Those who

WESTAR ENERGY 2014 ANNUAL REPORT choose can sign up to have us text them to let them know when their power is out, when we expect it will be restored, and then confirming for them that their lights are back on, in case they're not home at the time.

We're installing digital meters to provide customers with more choice and control. Digital meters let customers track and manage their energy purchases and even alerts them when they meet their defined energy budget criteria. These digital meters also alert us to power outages, helping restore service more quickly and efficiently. They also save money and resources by allowing us to perform tens of thousands of service calls without having to send out a crew or service truck.

These changes make our business easier for our customers. If given a choice, we want our customers to choose us because we listen and adapt to changing needs Meet Javier Garcia, a chemical engineer at our that power their lives - one home, one business and one community at a time.

to nature at our power plants. Together, we make Kansas a betterplace to live.

At our Jeffrey Energy Center, we recently rebuilt systems to remove almost all the sulfur dioxide emissions. Recognizing the need to release clean water from our power plants, we sought a natural and cost-effective way to ensure our water releases met our high environmental standards. Our engineers determined a wetlands project could likely fit the bill, so they built a small, pilot wetland to test their analysis. When they were proved right, they expanded the idea with a full-scale wetlands - and earned Westar the Edison Electric Institute's Edison Award, the electric power industry's honor for innovation. We're incredibly proud of our employees' creativity and ingenuity to develop a natural solution that will save our customers tens of millions of dollars, and help conserve the environment.

Last summer, we worked closely with landowners, communities, government leaders and environmental organizations as we constructed a high-capacity transmission line in southcentral Kansas. We built the line as part of a joint venture: Prairie Wind Transmission. The line will serve as an electric energy super highway between eastern and western Kansas, promoting renewable energy in Kansas, providing greater access to lower-cost electricity and improved reliability throughout the region. We completed the project several months ahead of schedule and $60 million under budget.

While more energy companies seemingly double down on just one or two ways to make electricity, we continue to believe in the merits of a diversified energy portfolio. In December, we announced we will add another 200 megawatts (MW) of wind energy to our renewable energy portfolio, bringing the total to nearly 1100 MW. Diversification contributes to increased reliability and more stable prices for our customers.

It's been four years since we last filed a general rate application. This year we filed a request with the Kansas Corporation Commission to increase our prices to reflect the costs of meeting tough new environmental mandates and to provide more reliable service.

Upgrades and ongoing maintenance are much less expensive than building new plants and are among the many ways we keep our costs under control.

Making these upgrades maintains the diversity of our power plant portfolio, and preserves hundreds of jobs - jobs vital to our Kansas communities and that infuse the local tax bases with nearly $125 million a year, much of which funds our schools. Meet Naomi Peterson,a Westar Energy retiree from Emporia.She has been a Westar Green Our customers depend on their electricity being reliable. While our ReliabiliTree* Team volunteer since the Green Team began tree trimming program has cut tree-related outages by two-thirds - even more in 1989. In 2014, the Green Team celebrated in some communities - we also must maintain our equipment. We want to be 25 years of giving back to the communities we proactive and replace outdated equipment that causes power outages, particularly serve. Completing about 70 projectsper year in storms. For some of our business customers, even a blink in their electricity on weekends and evenings, the Green Team can cost them thousands of dollars in lost inventory and productivity. In addition collaborates with conservationgroups, non-profit to the inconvenience, power outages also create health and safety risks to our agencies and schools to enhance and foster an communities. Taking a proactive approach helps keep those to a minimum. understandingof Kansas' natural resources.

Our customers also tell us they would like choices in how they use and pay for their electricity. Today our customers have only one rate plan, so we are asking our regulators for permission to offer new pricing plans that give customers choice in how they budget for and use electricity. One of the plans is designed specifically to reduce the volatility associated with higher summer bills. Another rewards customers who can spread out the power they use instead of using a lot of it at once, which reduces demand on equipment.

Even with a necessary increase in prices, our electricity provides tremendous value: not only economic - most of our customers can power their entire home for a full day for about the cost of a gallon and a half of gas - but also because of what it provides us and our communities in terms of safety, security, comfort, productivity and convenience.

WESTAR ENERGY 2014 ANNUAL REPORT TAKING EMPLOYEES TO HEART We're proud of our people and our positive culture. We applaudtheir dedicationto safety, diversity, leadership,innovation and doing what is right.

Safety continues to be at the forefront of everything we do. In 2014, Westar Energy was selected by EHS Today as one of America's Safest Companies. EHS Today highlighted our commitment to protecting our employees, the environment and the communities we serve.

Focusing on the future is another theme that runs deep at Westar Energy. In the

In Topeka, we had five substations that had reached obsolescence and could be replaced by a single modern substation. Replacing infrastructure in an urban area is always a challenge, but our employees, working with education leaders, developed a plan to hide the new state-of-the-art substation right in plain sight by designing it as Westar's Education Station, an outdoor classroom where students learn the science behind electricity. It provides customers with more reliable electric service and supports economic growth in our community as demand for electricity continues to grow.

We also completed our first full year supporting the Westar Energy Power Lab at Wichita State University, an expanded and updated laboratory where WSU College of Engineering students learn about power systems.

Ultimately, ours is a business that can only be as successful as the communities we have the privilege of serving. Providing time and resources for our employees to demonstrate leadership through volunteer service not only builds greater job satisfaction and fulfilling careers for our dedicated staff, but also helps push Kansas forward.
