Duke Energy's New Citrus Combined-Cycle Natural Gas Plant Up and Running
LCG, December 7, 2018--Duke Energy recently announced that its new gas-fired power generation facilities at the Crystal River Energy Complex are now operational and delivering power to the grid in Florida. The newly completed $1.5 billion project adds 1,640 MW of new capacity and will replace generation from plant retirements, including two 1960s-era coal-fired units and a nuclear plant.
The new Citrus Combined-Cycle Natural Gas Station includes two combined-cycle power blocks, each with an electric generating capacity of 820 MW. The first power block commenced operations on October 26, and the second power block commenced operations on November 24. Duke Energy broke ground on the project in March 2016.
Each power block employs a two-on-one design, with two combustion turbines and one steam generator. The combustion turbines are G-series from Japan's Mitsubishi Hitachi Power Systems.
The new facilities are co-located at the 5,100-acre Crystal River Energy Complex on Florida's Gulf Coast, about 85 miles north of Tampa. The natural gas-fired facilities will generate power with low emissions; sulfur dioxide, nitrogen oxides and other emissions are expected to drop by 90 percent in comparison to the operation at Crystal River coal-fired units 1 and 2.
Duke Energy announced the decision to retire these coal units in May 2014 due to changing federal environmental regulations. The coal-fired units will formally retire in December, and the demolition process is expected to last through 2023.
"The high-tech facility represents a $1.5 billion investment in Citrus County, surrounding communities and Florida - underscoring our continued commitment to our customers and the environment," said Duke's vice president of fossil/hydro operations in Florida. "The station will provide a smarter energy future for Floridians by generating cleaner, more efficient energy."
The new station receives natural gas through the new 515-mile Sabal Trail pipeline. The $3.2 billion pipeline starts in Alabama, extends through Georgia and ends in central Florida. Duke Energy is a 7.5-percent owner of the pipeline.
