Turkey Point Extended Power Uprate
Power uprates – modification of existing plants and associated licenses to generate additional electricity – enable a utility or plant owner to produce additional electricity without building a new plant.
The uprate project at Turkey Point Nuclear Generating Station, a half hour south of Miami on Biscayne Bay, as well as at its sister facility, St. Lucie, up the Atlantic coast represents one of the largest uprate projects performed in the history of U.S. commercial nuclear plants. The uprates yielded 30 percent more power than originally anticipated, allowing customer Florida Power & Light to add more than 522 megawatts of capacity without creating greenhouse gases. That’s enough to power more than 300,000 Florida households annually.
Bechtel performed uprates on a total of four nuclear generating units, two at each plant. These major construction activities were performed while one unit―and sometimes both―were in operation. This regimen required highly detailed and complex planning, and much cooperation with Florida Power & Light, to meet tight schedules, while maintaining safety and quality standards.
Bechtel aligns its capabilities to our customers’ objectives. We have completed seven extended power uprate projects since 2009. In addition to the work on the Florida units, the company also completed extended power uprate work at Florida Power & Light's Point Beach nuclear facility in Wisconsin in 2011.
Power Engineering magazine awarded Bechtel and Florida Power & Light its 2013 Nuclear Project of the Year Award. The companies won for the extended power uprates at the Turkey Point and St. Lucie nuclear plants. The combined work at these plants represents one of the largest uprate projects performed in the history of U.S. commercial nuclear plants.
Uprates Provide Additional Power
Uprates modify existing plants and associated licenses to generate additional electricity instead of building a new plant. Bechtel’s work for Florida Power & Light was an extended power uprate, by which we increased the enrichment of the nuclear fuel and then modified equipment to use the additional power.
Typical of extended uprates, including those at Turkey Point and St. Lucie, Bechtel installed new equipment such as high-pressure turbines, low-pressure turbines, generator rotors, moisture separator reheaters, condensers, and startup transformers. In all, the team made more than 120 major modifications to the units.
Such improvements not only boost output, they increase efficiency, reliability, and safety.
