EPRI and the Tennessee Valley Authority successfully test largest ever use of renewable diesel in power production

In Tennessee, EPRI and the Tennessee Valley Authority (TVA) announced the successful demonstration of renewable diesel as a combustion turbine fuel for power generation. The demonstration—the first U.S. test and the largest conducted in the world—was performed on a 76-megawatt dual-fuel natural gas/diesel unit at TVA’s Johnsonville site in Tennessee.

EPRI collaborated with TVA’s Innovation & Research and Johnsonville Operations teams to evaluate the gas turbine across a full range of operating conditions, including at full load with no turbine or control system modifications. The test demonstrated how renewable diesel could support near-term decarbonization of dispatchable thermal power generation assets, providing on-demand power with up to 75 percent fewer lifecycle greenhouse gas emissions compared to conventional diesel.
