Generation

Tenaska Generation is an industry leader with unmatched performance and a proven history of safety and operational excellence. We manage a fleet of 6,622 MW generation capacity across 16 facilities in 8 states. Our portfolio includes natural gas, wind and solar.

As a physical asset owner with decades of experience, we bring expertise across the full spectrum of generation management. Our team has extensive knowledge in strategic planning, commercial optimization, plant operations, technical services, engineering, risk management and financial structuring.

Committed to safety

We are committed to ensuring our assets are high performing and safe. Year after year our fleet is recognized for going beyond what’s expected, evident in our participation in the U.S. Department of Labor Occupational Safety and Health Administration’s (OSHA) Voluntary Protection Program (VPP) and the National Safety Council (NSC).

Community investment

Tenaska’s commitment to the communities where we operate goes beyond generating power. Our facilities contribute significant tax revenue to local governments and schools, and for more than 20 years, we’ve supported high school students through the Tenaska Scholarship Program, providing more than $1 million in scholarships to college-bound students. We also provide resources to local first responders, build lasting relationships with neighbors, and show up as engaged members of the communities where we live and work.
