Byron Generating Station Celebrates 4,500 Consecutive Days of Carbon-Free Nuclear Power Production & 45th AnniversaryByron Generating Station Celebrates 4,500 Consecutive Days of Carbon-Free Nuclear Power Production & 45th Anniversary<div><strong>BYRON, Ill.</strong> — Today the Byron Generating Station in Northern Illinois is celebrating an impressive 4,500 consecutive days producing carbon-free energy for Illinois and beyond, while also marking 45 years on site. Employees, retirees and local leaders will be on hand today for a 1 p.m. cake cutting to mark the occasion. Oregon’s own O’s Bakery has designed an incredible edible replica of the plant for the occasion.<br></div><div><br></div><div>Construction work started at the Exelon Generation location in Byron in 1975, with the Unit 1 reactor coming online in 1985 and Unit 2 in 1987. Nuclear reactors like the ones at the dual-unit Byron Station are very reliable, running around the clock. Every 18 months, operators shut down a reactor for only few weeks to support refueling and maintenance. Over the past 13 years, when one reactor shut down for maintenance, the other unit stayed online allowing the facility to continuously provide electricity to the region. The nuclear plant’s 700-plus workforce prides itself on precision monitoring and maintenance programs, which help the plant sustain its status as a model of reliability.</div><div><br></div><div>The plant generates enough carbon-free electricity to power more than 2.3 million homes and businesses while preventing the release of nearly 12 million metric tons of carbon dioxide annually. Over the lifetime of both units’ operation, that’s the equivalent of taking approximately 2.5 million cars off of the road every year.<br></div><div><br></div><div>“Clean power-generating facilities like Byron Station are on the front lines of combatting climate change,” said Byron Station Site Vice President Mark Kanavos. “Americans want carbon-free electricity, which our nuclear plants deliver to millions every day. They also want reliability, and nuclear plants are the unquestioned champion of reliable electricity production in this country.”</div><div><br></div><div>The average nuclear plant in the United States operated at full power about 92 percent of the time of 2019. On average, Exelon’s nuclear plants ran at full power more than 95 percent of the year. Byron Station topped the company’s and country’s average run time by operating at full power more than 96.9 percent of the time in 2019. The always-on aspect of nuclear power isn’t lost on its residents.</div><div><br></div><div>“Living in this area my whole life, I can attest to the importance of the station for both its important part in electricity distribution and its positive effect on the economy,” said Sarah Downs, executive director of the Byron Area Chamber of Commerce. “When one reactor goes offline for a maintenance project, there’s still a positive outcome as local businesses see a big uptick in sales. With hundreds of contractors temporarily staying in the area during refueling projects, our business owners are staffing up – with some even extending their hours – to take care of the workers visiting our shops, restaurants and stores.”<br></div><div><br></div><div>Byron Generating Station is in Ogle County, Ill., about 20 miles southwest of Rockford. With both units at full power, the site produces almost 2,500 megawatts, enough electricity to power more than 2.3 million average American homes.</div><div><br><br></div><p><br></p> 10:00:00 PM
Calvert Cliffs Refueling Outage Powers Local EconomyCalvert Cliffs Refueling Outage Powers Local Economy<p>Operators at Exelon Generation’s Calvert Cliffs Nuclear Power Plant removed Unit 1 from service just after midnight Sunday to begin a planned refueling outage, capping a run of 702 consecutive days of power generation for the unit.  This reliable operation enabled the station to generate more than 15 million MWh of carbon-free electricity for customers. That amount of clean energy has the emissions avoidance equivalent of taking more than 2.3 million passenger cars off the road for one year. <br></p><p>Work completed during the refueling outage will help the unit deliver zero-emission, reliable power to almost a million homes and businesses during the next two-year operating cycle. <br></p><p>To support the refueling outage, approximately 1,000 additional workers will travel to Calvert for several weeks, filling nearby hotels to capacity and increasing foot traffic in restaurants and shops at a time when tourism is usually slow.<br></p><p>“The refueling outage at Calvert Cliffs Nuclear Power Plant is a welcomed addition to our local economy each and every year,” said Kelly McConkey, President, Calvert County, Maryland Board of County Commissioners. “We welcome the skilled workforce to our community to support Calvert Cliffs and greatly appreciate the influx of spending at our local business establishments during the winter months.”<br></p><p>While the unit is offline, technicians will replace nearly one-third of the reactor’s fuel and perform more than 7,500 inspections, tests, maintenance activities and modifications. Many of the tasks performed during the outage cannot be accomplished while the unit is online. <br></p><p>“We are proud to produce almost a third of Maryland’s power with, safe, reliable, carbon-free nuclear generation,” said Calvert Cliffs Site Vice President Mark Flaherty. “These investments in state-of-the art equipment and new technologies will help ensure safe, reliable operations for years to come.”  <br></p><p>Calvert Cliffs is located on the western shore of the Chesapeake Bay in Calvert County and is Maryland’s only nuclear energy facility. The station is home to two pressurized water reactors capable of generating more than 1,800 megawatts combined, providing approximately 80 percent of Maryland’s clean energy and powering more than 30 percent of all homes and businesses in the state. <br></p> 2:00:00 PM
LaSalle Generating Station Refueling Outage Powers the CommunityLaSalle Generating Station Refueling Outage Powers the Community<p>Operators at Exelon Generation’s LaSalle Generating Station removed the Unit 1 generator from service early this morning to begin a planned refueling outage. Work completed during the nuclear plant’s outage will help deliver reliable, carbon-free electricity to Illinois customers during the next two-year operating cycle.</p><p>To support the work, the station will use the talents and expertise of more than 1,000 additional workers, many of whom travel to LaSalle County from outside the area. For several months preceding and following the outage, the influx of workers provides a significant boost to the local economy.</p><p>“When the extra workers come to LaSalle Station for the refueling outage, it means additional business for our community,” said Jeff Hettrick, executive director of the Ottawa Chamber of Commerce. “Ottawa and LaSalle County appreciate the additional workers who take advantage of all the services we have to offer, whether it’s our restaurants, hotels or shopping.”</p><p>During the outage, technicians will complete testing, maintenance and modifications that can only be done when the station is not generating electricity. LaSalle Unit 2 will continue to operate at 100 percent power while Unit 1 is offline.</p><p>“It is our goal here at LaSalle Station to continue operating at world-class levels of safety and reliability,” said John Washko, LaSalle Generating Station site vice president. “The work completed during our refueling outages helps us meet that goal and enables us to power a cleaner and brighter future for the communities we serve.”</p><p>LaSalle Generating Station is a nuclear power facility located about 75 miles southwest of Chicago near Marseilles, Ill. At full power, the facility’s two reactors produce more than 2,200 megawatts of carbon free electricity, enough to power 2.3 million typical homes.<br></p> 2:00:00 PM
