LAFOX, Ill., Aug. 20, 2025 (GLOBE NEWSWIRE) -- Governor JB Pritzker, the Illinois Department of Commerce and Economic Opportunity (DCEO), and Richardson Electronics, Ltd. (NASDAQ:RELL),– a leading global manufacturer of engineered solutions, green energy products, power grid and microwave tubes and more – today announced the Company will expand its operations at its manufacturing headquarters in La Fox, Illinois. Richardson Electronics plans to make a capital investment of more than $8.5 million over the next four years with support from the Reimagining Energy and Vehicles in Illinois (REV Illinois) program. The Company plans to expand its operations, retain nearly 200 skilled employees, and create 54 new full-time jobs in the region.

“Here in Illinois, we’re committed to building a clean energy economy to help power our planet while supercharging the state’s economy,” said Governor JB Pritzker. “With unmatched infrastructure, a qualified workforce, and competitive incentives, Illinois continues to attract clean energy investments from companies like Richardson Electronics, creating new jobs for Illinoisans and strengthening our reputation as a leader in the clean energy economy.”

“Illinois continues to lead the way in clean energy innovation and advanced manufacturing, and Richardson Electronics’ expansion is a testament to that momentum,” said DCEO Director Kristin Richards . “Through the REV Illinois program, we support companies that are growing their footprint in our state, creating high-quality jobs, and advancing our transition to a clean energy economy here in Illinois.”

Richardson Electronics will build upon its existing alternative energy business to develop next-generation energy storage products that support electric grid stability. The Company will invest in equipment and structural upgrades in order to research, develop, and produce next-generation battery energy storage system (BESS) technologies at the Company’s Illinois manufacturing facility. These technologies are designed to address brownouts, reduce electricity costs, and support renewable energy integration, while demonstrating the commercial viability of long-duration energy storage (LDES). The Company’s BESS technology is being developed for industries such as manufacturing, healthcare, and critical infrastructure operations.

"We are proud to launch this energy storage system initiative, which reflects our continued commitment to innovation, community impact, and long-term growth," said Greg Peloquin, Executive Vice President and General Manager of Power & Microwave Technologies and Green Energy Solutions . "We extend our sincere thanks to Representative Dan Ugaste, Kane County board member Rick Williams, and the team at DCEO, for their leadership and steadfast support. Their partnership has been instrumental in making this project a reality for Richardson Electronics, our customers, and the people of Illinois.”

Richardson Electronics’ decision to expand their operations within Illinois builds upon the numerous manufacturing companies that have also recently chosen to establish or expand their business in the state, including Pure Lithium and Adient , due to the state’s skilled workforce, strong infrastructure and commitment to clean energy.

Guided by Illinois’ Economic Growth Plan , the REV Illinois program supports a targeted industry for the state – clean energy production and advanced manufacturing – which continues to grow with assistance from Illinois' leadership and their support of innovative technologies that reduce costs and emissions. As part of the State's incentive package, Richardson Electronics received a REV Illinois tax credit for their capital investment and commitment to job creation. The REV agreement also specifies the retention of 190 jobs for the entirety of the agreement period. A link to the full Richardson Electronics agreement can be found here .
