Lincoln Combustion Turbine Station Expansion

To ensure reliability and provide energy when customers need it the most, Duke Energy is investing in a new 402-megawatt simple-cycle unit at the existing Lincoln Combustion Turbine Station near Denver, N.C. 

The 16-unit, 746-acre site is ideal for expansion because of available land and access to existing transmission and natural gas connections. 

The North Carolina Utilities Commission approved the project in December 2017, and construction started in September 2018.

Siemens delivered the generator and combustion turbine to the site in May and November 2019 respectively, and construction is expected to be completed in 2020 followed by four years of unit testing.


When fully operational in 2024, the new unit will be the most efficient simple-cycle combustion turbine in Duke Energy’s fleet and about 34% more efficient than the existing combustion turbines at the Lincoln site. 

Innovative agreement and customer benefits

Duke Energy and Siemens have an innovative agreement that allows Siemens to build and test its newest advanced natural gas combustion turbine technology at the Lincoln site. 

Duke Energy customers will receive the unit’s energy during the four-year testing period while only paying some fuel costs. 

When testing is completed in 2024, Duke Energy will begin operating the unit, which will supply enough energy to power more than 300,000 homes in the Carolinas. 

The new unit can also start quickly, giving Duke Energy more flexibility to support its growing portfolio of solar generation, helping the company to continue its plan to close older coal-fired units. 

Expanding the Lincoln Combustion Turbine Station represents an investment in a smarter, more efficient energy future that is providing millions in work to local subcontractors, creating more than 400 temporary jobs during the height of construction and increasing the local tax base.
