U.S. Nuclear Regulatory Commission Greenlights Constellation’S $167 Million Digital Modernization Plan for Limerick Clean Energy Center; State-Of-The-Art Technology Upgrades Will Enhance Reliability, Diagnostic Capability and Cyber Resilience Constellation announced the U.S. Nuclear Regulatory Commission (NRC) has approved a License Amendment Request for the Limerick Clean Energy Center’s Digital Modernization Project, a first-of-its-kind upgrade across major control and protection systems that will enhance reliability, diagnostic capability and cyber resilience at one of the nation’s top-rated nuclear facilities. This approval comes at a critical time as Constellation works to preserve and expand nuclear generation in Pennsylvania.
The Digital Modernization Project replaces select analog instrumentation and control equipment with state-of-the-art digital platforms designed to improve equipment monitoring, provide a broader range of automation and support additional operational flexibility with enhanced reliability. These upgrades will help Limerick deliver around-the-clock, carbon-free electricity to power homes, businesses and new data-driven industries that are creating jobs in the region. This is the first large-scale demonstration of a digital safety system upgrade at an operating U.S. nuclear plant, supported by the U.S. Department of Energy’s (DOE’s) Light Water Reactor Sustainability Program. The Digital Modernization Project installation will be done in phases and carefully managed to ensure safety and operational continuity. Physical installation of the digital control rooms is planned to occur during upcoming refueling outages. During these scheduled outages, Limerick will welcome thousands of additional skilled craft workers to support the work, providing a boost to the local economy through a surge in spending on lodging, dining and services. Located along the Schuylkill River in Montgomery County, Pennsylvania (about 35 miles northwest of Philadelphia), Limerick’s two nuclear units provide up to 2,317 megawatts of reliable, carbon-free electricity, enough to power more than 1.7 million homes. The station supports local jobs and economic activity, while contributing to regional clean-energy goals. Tillkännagivande • Dec 17
the Nuclear Regulatory Commission Approves 20-Year Initial License Renewal for Constellation's Clinton Clean Energy Center The Nuclear Regulatory Commission (NRC) has approved a 20-year initial license renewal for Constellation's Clinton Clean Energy Center and a 20-year subsequent license renewal for its Dresden Clean Energy Center, following a rigorous review of maintenance activities, plant equipment and safety systems at the two Illinois facilities. The approvals allow Clinton to operate through 2047 and the Dresden reactors to operate through 2049 and 2051. Constellation, the nation's largest operator of clean, reliable nuclear power, is investing more than $370 million to relicense the plants, installing upgrades to increase efficiency and ensure safety and reliability for decades to come. At Clinton, two new auxiliary transformers and two advanced equipment chillers are delivering higher system reliability, while upgrades to the plant's condensate polisher system offer greater protection from component degradation. At Dresden, operators are now using next-generation feedwater level control technology to enhance reactor safety, while a new main power transformer purchased for the plant will deliver electrical system monitoring and control. With these and other upgrades in place, Clinton and Dresden continue to operate at higher levels of safety, reliability and efficiency than the day they came online. While these license renewals give Constellation the regulatory approval needed to operate Clinton and Dresden for another two decades, actual operation is contingent on each plant's financial viability. At Clinton, the facility's carbon-free energy is secure as a result of the 20-year agreement with Meta announced in August. The deal supports the continued operation, expansion and relicensing of the 1,121-megawatt Clinton facility following the expiration of the state's Zero Emission Credit (ZEC) program in May 2027.

Constellation Energy Corporation Receives Regulatory Approval from the New York State Public Service Commission Constellation announced it has received regulatory approval from the New York State Public Service Commission (PSC) for its previously announced acquisition of Calpine Corporation. The approval represents the most recent key step forward in Constellation’s plans to combine the nation’s largest zero-emissions nuclear fleet with Calpine’s premier portfolio of low-emission natural gas and geothermal assets. The deal will establish a coast-to-coast platform capable of supporting growing demand for around-the-clock, sustainable power. Earlier this month, the deal cleared regulatory review with Texas’ Public Utilities Commission. The transaction — expected to close in the fourth quarter of 2025 — now awaits approval from the Federal Energy Regulatory Commission and the Department of Justice, along with other customary closing conditions.
