The Challenge: Transitioning from Coal to Clean Natural Gas
The Cumberland Fossil Plant, built in 1973, has been the largest generating asset in the Tennessee Valley Authority (TVA)’s coal fleet for over 50 years. However, changing grid dynamics, environmental regulations and operational challenges made replacement essential.
TVA needed to retire this 2,470-megawatt coal facility while maintaining reliable power for 840,000 Tennessee Valley homes with zero tolerance for grid instability during the transition.
Project Challenges
- Replacing the largest coal plant in TVA’s fleet while maintaining grid reliability
- Meeting the aggressive 2026 deadline to replace the first coal unit before retirement
- Chemical cleaning is critical to ensure plant components meet stringent cleanliness standards
- Complex coordination across 1,900+ workers on an active power generation site
- Navigating the EPA’s environmental concerns while delivering on schedule
- Building alongside operational coal units requires extreme safety protocols
B&W’s Role: Critical Chemical Cleaning Services
B&W Energy Services was selected to provide essential chemical cleaning services for this landmark energy transition project. Our work ensures that piping systems and other critical systems meet the cleanliness standards required for reliable combined-cycle operation.
Why B&W for This Project
TVA and contractor Kiewit needed a chemical cleaning partner with:
- Proven experience in large-scale power generation projects
- Ability to work safely on occupied sites alongside active coal operations
- Advanced chemical cleaning protocols for combined-cycle plants
- Track record of on-time delivery for mission-critical infrastructure
- Expertise in pre-commissioning natural gas power facilities

Project Overview: A Historic Energy Transition
The Cumberland Natural Gas Plant represents one of the most significant energy infrastructure projects in the Tennessee Valley. This $2.1 billion facility will replace one of the aging Cumberland Fossil Plant’s units.
The new state-of-the-art natural gas plant will deliver 1,450 megawatts of firm, dispatchable power capable of serving 840,000 homes while reducing carbon emissions by up to 60% compared to the coal facility. Construction began in 2023, with commercial operation scheduled for late 2026.
The project includes the construction of 12 pre-engineered metal buildings and supporting infrastructure, a 32-mile natural gas pipeline and extensive transmission upgrades. Nearly 1,900 workers are currently on-site, making this one of the largest active construction projects in Tennessee.
