Duke Energy is now generating more than 25 percent of its electricity from natural gas in North Carolina and South Carolina, Duke CEO Lynn Good said in an Aug. 4 quarterly earnings conference call.
“So if you go back to 2008, 2009, 2010, the Carolina companies had very little generation coming from natural gas,” Good told financial analysts during the call. “That, today, is in the range of 25 percent to 30 percent of our energy is coming from natural gas,” Good said.
“So we made an investment in the Atlantic Coast pipeline, [a] $2 billion investment, to bring more infrastructure into the state to provide infrastructure for further development of generation and also services to customers,” Good said, according to a transcript of the call from Seeking Alpha.
Duke is investing in both new natural gas power plants as well as interstate natural gas pipelines, Good said.
Duke is in advanced development, or actual construction, of new gas generation in Asheville, North Carolina (as part of the Western Carolinas modernization project), the Lee combined-cycle plant in South Carolina, the Citrus County combined-cycle plant in Florida, the Osprey combined-cycle plant in Florida and the Hines chiller project, which is expected to enter service around Oct. 1.
“We made an investment in Sabal Trail, which is important to Florida, which is already a very gas-heavy area,” Good said. Sabal Trail is a 515-mile interstate natural gas pipeline to provide transportation services for natural gas power plants in Florida.
Duke has a 7.5 percent stake in the Sabal Trail pipeline, which is targeted to be in-service in mid-2017. The project is fully subscribed and will, among other things, served the planned Duke Citrus County combined-cycle gas plant in Florida.
In addition, Duke is acquiring Piedmont Natural Gas, which will become a Duke unit. Duke (40 percent) and Piedmont (10 percent) are among the owners in the 550-mile Atlantic Coast pipeline that will stretch from West Virginia into eastern North Carolina.
