Company Overview

The energy industry is in a state of perpetual motion. A steady stream of innovations change the way energy is produced, delivered and consumed. But one thing remains constant: Tenaska’s ability to succeed in the present even as we shape the future.

As an industry leader, Tenaska doesn’t just react to change; we leverage it to find new and unique opportunities to create value. We drive. This is a company that began as a five-person operation in 1987 with plans to build just one or two power plants. Today’s Tenaska is one of the largest privately held companies in the United States, a 700-person-strong organization that’s adept in natural gas marketing, power management, development and acquisition of generation assets, operation of power plants and more.

The same entrepreneurial spirit behind our success thus far continues to propel our evolution within and beyond industry changes. We develop forward-looking solutions to fit customer needs and meet market demands, priding ourselves on adding value for customers, partners and investors.

We’ve created a culture where our people are free to build the future of the energy industry on a decades-strong foundation of ethics, expertise and entrepreneurship.

It’s in our mission statement: To be an ethical, highly respected, socially responsible company that provides outstanding customer service and value in marketing natural gas and electricity and in owning and operating energy assets safely and reliably.

Operating ethically is as important to our company’s leaders as providing outstanding service and value. That may explain why we have relationships with customers and partners that stretch back many years, even as the energy industry undergoes rapid and continuous evolution. They know what we know – that Tenaska puts a premium on conservative business practices, unwavering honesty, professional expertise and responsible commitment to the environment, safety and the communities where we operate.
