Duke Energy announced plans to partner with Siemens to test new gas turbine technologies at an expansion of its Lincoln County Combustion Turbine generation site in Denver, North Carolina.
Duke has submitted plans for the turbine proposal to the North Carolina Utilities Commission. Siemens will act as the engineering, procurement and construction contractor.
Though the companies did not specify the capacity of the turbine, Duke said the company will need 400 MW of peaking energy for customers in the Carolinas by 2024, and that early approval will allow Siemens to build and test its technologies in time to meet that need.
Duke estimated the finished turbine would be 25 percent more efficient than the existing Lincoln County turbines.
This unique arrangement with Siemens offers a significant cost savings to our customers while providing one of the most advanced, efficient gas turbine units in the U.S.,” said David Fountain, Duke Energy’s North Carolina president. “This new technology will provide us with flexible peaking power needed to complement intermittent solar energy resources for our customers and lower emissions across our fleet.”
Construction could begin as soon as mid-2018, with gas turbine testing in 2020. The Lincoln County Combustion Turbine currently features 16 gas-fueled, simple-cycle combustion turbines with a combined capacity of 1,200 MW for short-term use during peak consumption.
