Duke Energy is firming up plans to add a large natural gas plant at Lake Norman in Catawba County, with construction expected to start in 2026 if approved by regulators.
The two combustion turbines fired by natural gas would produce as much as 900 megawatts, capable of powering more than 700,000 homes. It would also enable Duke to retire the oldest two units, producing 760-megawatts, at the Marshall Steam Station plant, which started in 1965. It has two other units expected to operate through 2031.
The new plant would go into service in 2028, pending approval by the N.C. Utilities Commission. A decision is expected later this year.
The Environmental Defense Fund and other environmental groups are pressing Duke to expand alternative energy generation rather than investing in more natural gas-powered plants. But the third-largest U.S. electric utility, based on stock market value, views natural gas as an essential bridge to meet its promise to reduce greenhouse gas emissions over the next few decades.
