US power utility Duke Energy has received the approval from the North Carolina Utilities Commission (NCUC) to build two 280 MW gas-fired CCGT units on the site of its Asheville coal-fired power plant in North Carolina (United States).
The coal-fired power plant consists of two units commissioned in 1964 (191 MW) and in 1971 (185 MW), while two gas turbine units were added in 1999-2000 (327 MW). In May 2015, the company announced that it would retire its 376 MW Asheville coal-fired power plant by 2020 and would invest US$750m in the construction of a 650 MW gas-fired power plant (including solar generation capacity) on the site. Duke Energy has now decided to replace the coal-fired units by two 280 MW gas- and oil-fired CCGT units (instead of a single 605 MW unit) by 2020; a third, simple-cycle, 190 MW unit could be added in 2023 or later. Total investment is estimated at US$1.1bn. Construction is expected to start in 2016 for commissioning in late 2019.
